About the role
We’re hiring a GTM Engineer to build the systems that power our growth function. This role sits at the intersection of GTM, operations, and Engineering. You’ll own the internal infrastructure behind how we run CRM, outbound, paid acquisition, SEO / GEO, and future growth channels. You’ll help turn a set of tools and workflows into a cohesive, scalable system the team can rely on as we grow.
What they're looking for
- Experience with CRM systems, outbound tools, paid ads, and SEO / GEO workflows
- Experience automating workflows either through workflow automation tools like Zapier or via Claude and other AI tools
- Strong technical fluency, including comfort with SQL, analytics, automation, and systems thinking
- A builder mindset. Practical, adaptable, and excited to create structure in ambiguous environments
- Relentlessly curious. You don't wait to be pointed at the answer - you go find it, and you know when to pull in someone who knows more than you
- Strong communication skills. We work at an extremely fast pace, so clear, concise communication is essential
More about this role
Every breakthrough in trade infrastructure has followed the same pattern: reduce a transaction cost, expand the market. Containerization for goods. SWIFT for money. Stripe for payments. Compliance is one of the last and largest — and the hardest, because trade rules aren't data to be looked up. They're a complex adaptive system with 190+ sovereign jurisdictions, in different languages, changing constantly, reacting to each other.
Sphere built the system that solves it. Our AI (TRAM) ingests global trade law, interprets it, resolves conflicts across jurisdictions, and produces compliance determinations more reliable than human experts. We handle the entire lifecycle — calculation, registration, filing, remittance — at millisecond latency with zero downtime.
Backed by a16z and YC. $21M Series A, 30%+ month-over-month growth, customers include ElevenLabs, Replit, Deel, Runway, and Lovable.
Small team, global surface area . Everyone owns a domain that would be a full team at a larger company. San Francisco, being in office.
The problem keeps compounding. Expanding into input tax, withholding, e-invoicing, tariffs — each multiplies the complexity. Tens of millions of transactions...
