Startup Job Titles Explained: Who Does What at a Startup

Startup job titles describe a problem the company needs owned more than a rung on a ladder. A founding engineer builds the first product, a chief of staff extends a founder's reach, BizOps fixes whatever is most broken, an SDR books meetings and an AE closes them. The same title can mean a very different job at seed than at Series B, so read the responsibilities, not the label.

Definition: A startup job title is the name a young company gives a role, usually based on the main problem the person will own. Because startups are small and change fast, titles tend to be broader, looser and sometimes more senior-sounding than the same work would earn at a large company.

At a big company, a title tells you your level, your manager and roughly your pay.

At a startup it tells you what's on fire.

So "Head of Growth" can mean a solo marketer at a 6-person company or a director with a team of twelve. This guide is a glossary of the titles you'll meet most often, grouped by function, with what each tends to mean at different stages. For the full job-search process, see our playbook on how to get a job at a startup.

What jobs exist at a startup? It depends on the headcount

Before titles, size. Per Carta's State of Startup Compensation for the second half of 2025 (published May 2026), the median seed-stage company on its platform has just four employees, and average Series B headcount fell from 53 to 45 between 2023 and 2025.

Four people can't have a marketing department. So in practice, the jobs that exist look roughly like this, in our read:

Pre-seed and seed (2 to 10 people). Founders, engineers, maybe one generalist for operations or go-to-market. Titles are often "founding" something.
Series A (roughly 15 to 50). The first specialists: a first sales hire, a first marketer, a first designer, a first PM, a recruiter. "Head of" titles appear.
Series B and later (50+). Functions split into teams. SDRs and AEs separate, product marketing splits from growth, RevOps and BizOps show up, managers manage managers.

Engineering dominates the earliest hires. Carta's December 2025 analysis of tech startups found that roughly 70 percent of first hires are engineers, and at least 45 percent of the first five hires are in engineering. If you aren't technical, that's not a closed door, just a later one. Our guide to the best startup jobs by stage covers which of those roles tend to build a career fastest.

Leadership and early-team titles

Founder and co-founder. The people who started the company and usually hold the largest equity stakes. "Co-founder" is sometimes given to an early hire who joins before funding; ask what it means for equity and decision rights before you value it.

CEO, CTO, COO. At seed, the CEO is often the founder who sells and raises; the CTO is the founder who builds. A seed-stage CTO writes code most days. A Series C CTO mostly manages engineering leaders. Same title, different job.

Founding engineer. One of the first engineers, hired to build the product with the founders, usually with more equity and less process than later hires. Per Carta's data on grants over the two years to December 2025, the median first engineer at a tech startup received 1.54 percent of the company, with a wide middle half of grants starting at 0.61 percent (the post puts the top of that range at 3.5 percent in its summary and 4.13 percent in its body), and the median dropped to 0.61 percent within two more engineering hires. "Founding" is a timing word, not a level: it signals you joined early, not that you're senior.

Chief of staff. A senior generalist who makes a founder or executive more effective: running the operating cadence, driving cross-team projects, prepping board materials, filling gaps. First Round Review's guide to the role, written by a working chief of staff, notes that part of the job is figuring out what the job is. At seed, it often leans operational; at later stages, strategic. Our guide on how to become a startup chief of staff covers the path in.

"Head of" titles. Head of Sales, Head of Marketing, Head of People. At a startup this often means "first person in this function," not "leads a team." It can turn into a VP role if the company grows and you grow with it, or you can end up reporting to a new VP hired above you. Both are common.

Engineering and product titles

Software engineer (backend, frontend, full-stack). Builds the product. At early startups, "full-stack" is the default because nobody can afford specialists.

AI engineer or ML engineer. Builds features on top of models: retrieval, agents, evaluation, fine-tuning. In Carta's H2 2025 compensation report, the median initial equity grant for AI and ML engineers rose 31 percent from January 2024 to February 2026, against nearly 11 percent for individual contributors overall, which hints at demand.

Forward-deployed engineer (FDE). An engineer who embeds with customers and writes production code inside their systems, then feeds what they learn back into the product. Palantir, which popularized the role, contrasts it with product engineering as "one customer, many capabilities." The Pragmatic Engineer's explainer separates FDEs from solutions engineers, who mostly advise and build proofs of concept rather than shipping code on a customer's infrastructure.

Solutions engineer or sales engineer. The technical partner on sales deals: demos, technical questions, pilots. The BLS puts the median pay for sales engineers at $124,900 in May 2025.

Product manager (PM). Decides what to build and why, and works with engineering and design to ship it. The first PM at a startup often arrives around Series A, when founders can no longer hold the roadmap in their heads. "Product owner" sometimes means a narrower, delivery-focused version.

Product designer. Usually covers research, interaction design and visual design at once. Larger companies split those apart.

Go-to-market titles: growth, PMM, SDR, AE, CS

Growth (growth marketer, growth lead, head of growth). Owns getting more users or revenue through experiments across channels: paid ads, onboarding, referrals, pricing pages, lifecycle email. Growth roles tend to be more numerical and experimental than traditional marketing roles.

Product marketing manager (PMM). Owns positioning, messaging, launches and sales materials: how the product is described and to whom. Growth asks "how do we get more people in?"; PMM asks "what do we say, and to whom?" At a small startup, one person may do both.

SDR and BDR (sales or business development representative). Entry-level sales roles focused on booking meetings: cold email, calls, LinkedIn, following up on inbound leads. Some companies use SDR for inbound and BDR for outbound, others the reverse, and many use them interchangeably. Per The Bridge Group's 2025 SDR report (351 B2B companies, mostly SaaS), median SDR on-target earnings were $80,000, split $55,000 base and $25,000 variable, average ramp was about three months, and average tenure was 1.9 years. Our guide on how to get an SDR job goes deeper.

AE (account executive). Closes deals: runs discovery, demos, negotiation and contracts, carrying a revenue quota. A "founding AE" is the first salesperson after the founder, usually expected to build the playbook as well as sell.

Customer success manager (CSM). Keeps customers happy, adopting the product and renewing. Some CS teams own renewals and expansion revenue; others focus on onboarding and support. Ask which.

Partnerships or business development. Builds relationships with other companies (integrations, resellers, channel partners). At some startups, "BD" is just another word for sales.

Operations and strategy titles: BizOps, RevOps, ops

BizOps (business operations) or strategy and operations. A small team of analytical generalists who work on the company's most pressing cross-functional problems: pricing, planning, a new market, a broken process. Often hired from consulting or banking. Our guide on breaking into BizOps covers that route.

RevOps (revenue operations). Runs the systems and data behind sales, marketing and customer success: CRM, pipeline reporting, territories, comp plans, forecasting. Less strategy than BizOps, more systems.

Operations generalist or ops manager. At an early startup, the person who does everything that isn't building or selling: vendors, payroll setup, office, tools, compliance paperwork. A classic first startup job for organized people.

People, talent or recruiting. The first recruiter often joins around Series A. "Talent partner" usually means recruiting; "people" or "HR" covers benefits, policy and culture. Agency recruiters often fill this seat, and our guide on moving from recruiting into tech shows how.

Startup job titles and title inflation

Title inflation is when the title promises more seniority than the job delivers. It's common at startups for understandable reasons: a big title costs nothing, attracts candidates and flatters customers.

Founders disagree about whether that's a feature. In a 2011 a16z post, Ben Horowitz described two camps: Marc Andreessen, who favored generous titles as a cheap recruiting tool, and Mark Zuckerberg, who kept Facebook's titles deliberately modest to protect fairness and leveling. Horowitz's own conclusion was that either approach needs a disciplined process for levels and promotions behind it, which is a good thing to ask a startup about.

Here's how we'd read inflated titles:

A VP with no reports. At a 10-person company, "VP of Marketing" may mean you are the marketing team. That can be great experience. It's not the same as a VP at a 2,000-person company.
Director at Series A. Often means "senior individual contributor who might hire later."
"Founding" plus anything. Signals timing and equity expectations more than level.
Head of X. Usually the first hire in the function.

"Titles don't matter at a startup"

You'll hear this from founders a lot, and there's real truth in it. Inside a small company, what you own matters far more than what your email signature says, and fighting over titles early can look like the wrong priorities.

But.

Titles matter outside the company. The next employer, a recruiter's search filter and your own salary negotiation all read them. A senior title with junior scope can work against you if you later interview for a true VP role and can't speak to managing managers. In our view, the healthy approach is to accept a modest title if the scope is real, write the scope into your resume in plain numbers, and ask how titles and levels will be set as the company grows. Our guide on moving from a startup to big tech covers how big companies translate startup titles into levels.

How to read a startup job title before you apply

A short checklist that tends to cut through vague titles:

Read the first three responsibilities. They describe the real job. The title describes the hope.
Check the company's size and last round. A "Head of" at 8 people and at 150 people are different roles.
Look for who you'd report to. Reporting to a founder usually means more scope and less support.
Look for a number. Quotas, meetings booked or a growth target tell you how you'll be judged.
Ask how titles and levels are set. In the interview, ask whether the company uses a leveling framework and how promotions happen.
Compare the same title across a few companies. On the startup track of the 1752vc careers board, filter by a level such as Entry or Mid and read five postings with the same title; the spread in responsibilities shows how loose the label is.

A worked comparison: one title, two jobs

An illustrative pair. Both postings are titled "Growth Marketing Manager."

	Company A (seed, 7 people)	Company B (Series B, 90 people)
Reports to	CEO	Head of Growth
Owns	All acquisition, website, email, analytics	Paid search and paid social
Budget	Small, shared with founder	Dedicated channel budget
Measured on	Signups and first revenue	Cost per acquisition, pipeline

Company A is a generalist role closer to "first marketer." Company B is a specialist channel role on a team. Neither is better. They train different skills, and the right one depends on whether you want breadth or depth next.

Where to find startup roles by title

Once you know which titles fit, searching by them gets easier. Our roundup of the best startup job boards compares the main options. The 1752vc careers board's startup jobs track lists open roles at venture-backed startups with a US focus, refreshed every week, with each employer's own posting date and filters for level, location and time posted.

Common mistakes with startup job titles

Chasing the biggest title. A "VP" offer with no budget and no team may teach you less than a "Manager" role on a strong team.
Ignoring stage. The same title means different work at seed and Series B.
Skipping the level question. Ask how the company maps titles to levels and pay.
Undervaluing "ops" and "generalist" roles. They often give the widest view of how a company runs.

Where we land

Our take: treat a startup title as a headline and the responsibilities as the story. A modest title with real scope usually ages better on a resume than an inflated one with thin scope. When in doubt, ask what the person in this seat will own in six months.

That's one view. Some people deliberately take a big title early to accelerate a career, and sometimes it works.

The bottom line

A title tells you what the company calls the job.

The first three bullet points tell you what the job calls you to do.

Key takeaways

Startup job titles usually name a problem to own rather than a level in a hierarchy.
Stage changes everything: per Carta, the median seed startup on its platform has four employees, so early titles cover several jobs.
Engineers dominate early hiring; go-to-market, ops and specialist titles appear mostly from Series A onward.
Title inflation is common, so compare responsibilities, reporting lines and team size, not the label.
Before applying, read the first three responsibilities, the company's stage and who you would report to.

Frequently asked questions

What does a founding engineer do at a startup?

A founding engineer is one of the first engineers at a startup, building the product alongside the founders with little process and broad ownership. The role usually comes with more equity than later engineering hires; Carta's data on grants over two years to December 2025 shows a median of 1.54 percent for the first engineer. "Founding" signals timing, not seniority.

What is the difference between an SDR and an AE at a startup?

An SDR (sales development representative) finds and qualifies prospects and books meetings, usually through cold outreach and inbound follow-up. An AE (account executive) runs those meetings through demos, negotiation and closing, and carries a revenue quota. Many AEs start as SDRs, and at very early startups one person or the founder may do both.

What does BizOps mean on a startup job posting?

BizOps, short for business operations, is a small team of analytical generalists who tackle cross-functional problems such as pricing, planning, new markets or broken processes. It is more strategic than RevOps, which runs sales and marketing systems and data. Startups often hire BizOps people from consulting, banking or analytics backgrounds.

Is a VP title at a startup the same as a VP at a big company?

Usually not. At a small startup, a VP title often means the first or only person in a function, with little or no team. At a large company, a VP typically manages several managers and a large budget. When you later interview elsewhere, recruiters tend to weigh team size and scope more than the title itself.

What jobs exist at an early-stage startup?

At pre-seed and seed, most roles are founders and engineers, sometimes plus one generalist covering operations or go-to-market. From Series A, startups usually add a first salesperson, marketer, designer, product manager and recruiter. Specialist roles such as SDRs, RevOps, BizOps and product marketing appear more often from Series B onward.
