About PropelAuth

Team-based authentication for B2B SaaS. Backed by Y Combinator.

About the role

We pride ourselves on shipping code frequently and learning as we go. We also have critical security, performance, and uptime requirements, so finding the right ways to ship frequently within those requirements is very important. We all love to learn and grow. Our leadership team has experience working with and mentoring engineers at both startups and top companies. We'll work with our hires to craft this role to their interests, skill set, and long term career goals.

What they're looking for

  • Our core product is written in React / Typescript and allows our users to create configurable, but complex auth experiences. You will own both our customer's experience AND their users' authentication experiences
  • Our backend is written in Rust with a few parts in Python
  • Build configurable UIs / component libraries that can be embedded into our customers products. There's a lot of room to be experimental here and make delightful experiences for our customers' users
  • Build client libraries in a variety of different frameworks like React , React Native , Vue , and Svelte
  • Learn and support new auth standards like MCP or biometrics support
  • Be creative! In addition to auth, we want to provide our customers with all the tools they need to be successful. As a small team, we like supporting our employees ideas
More about this role

PropelAuth provides the right level of authentication for all stages of a company. New startups can use our hosted pre-built UIs which provide the simplest possible integration. Out of the box, our customers immediately have the same auth experience as large tech companies like Slack. As those startups grow, they can use our APIs and component libraries to pull aspects of the experience into their product.

We’re also working on auth for AI products and MCP servers. As agents start accessing data and taking actions on behalf of users, developers need to know which user and organization an agent represents, what it’s allowed to do, and how that access can be revoked. It’s a new version of the same problem we’ve always worked on: making powerful authorization models easy for developers to use.
