Summary Generated by Built In

Complete is on a mission to make compensation a winning advantage for the world's highest-impact companies. We are breaking compensation workflows out from spreadsheets and bringing them into the 21st century — think leveling and compensation cycle planning, total rewards statements for employees, interactive candidate offers, and much more!

Why Complete?

We realize that Compensation is a key determinant to a company's success (and their biggest spend!). Yet, enterprises lack the expertise to build and operate a defensible compensation strategy, making it one of the most costly mistakes to their financial and operational efficiency. We believe that companies with creative compensation strategies are winning today and will continue to do so.

Complete is backed by Accel and YC. We're also lucky to count technology leaders and operators like Will Larson (CTO of Carta), Eric Sagar (COO of Plaid), and Mathilde Collin (CEO of Front) as our angels and advisors.

Who we are?
  • 🎯 We’re exceptionally product-minded builders. We obsess over quality and believe that software built in the 21st century should not require product trainings.

  • 💜 Our culture is best described as low ego and painstakingly fast. Companies do not need big teams to prove PMF — they need focus.

  • 🥇We’re a small team of < 10 with exceptional product and business acumen. It’s allowed us to compete and consistently win against competitors and this is your chance to get in on the ground floor!

  • ⭐ Our customers include the likes of startups like Linear and Brex to public companies like Roblox, and we’re adding amazing logos to this list every day...

  • 🏢 We work in person in our SF office near Embarcadero BART, 4-5 days/week. We believe that bringing the most talented folks together in one room (with a lot of whiteboards) is the fastest way to win as a startup.

What are we looking for?

Complete is at an exciting inflection point and we’re looking for Senior or Staff Engineers to help scale us to a $XXM+ in ARR. You'll be a great fit if you like to move with urgency and high agency. We're engineers and builders obsessed with customer outcomes and love challenging the status quo. At a high level, there are three areas you can expect to lean on at Complete:

  • Ownership: We need experienced engineers who can own and grow entire lines of businesses end-to-end.

  • Autonomy: We value autonomy and believe that a small team of highly experienced product engineers can come together to create magic!

  • Scale: We're scaling! To new countries, to X0,000+ users, and to high-profile logos. We’re actively winning in the enterprise segment, which means working on deep and interesting problems like revamping our authorization, customizability, observability, security, and so on.

Tech stack

We believe the best engineers can operate in any tech stack, especially right now. Productivity is at an all-time high and we love our AI tooling (e.g. Claude Code, ChatGPT, Cursor) but here is our core stack:

  • Python (Django) with Postgres

  • GraphQL API (Strawberry)

  • React frontend + React Query

  • Clerk for auth

  • Merge for integrations with ATS and HRIS systems

  • Datadog, Sentry, LaunchDarkly

  • GitHub, Docker, Graphite, Slack, Notion, Linear

We want to see what else YOU might add to this list as we evolve!

Ready? Apply below! We can't wait because you might make us even more "Complete" 😉

Skills Required

  • Significant experience with Python and Django framework
  • Proficiency in PostgreSQL
  • Experience with front-end technologies, especially React
  • Familiarity with GraphQL APIs
