Job description

Full Stack Software Engineer

Corgi is rebuilding financial infrastructure from the ground up. Our vision is to unlock efficiencies in every corner of the financial stack. Anything that is a bottleneck or a genuinely hard foundational problem, we are going after it, beginning with insurance. There are extremely interesting problems throughout the full insurance lifecycle: computing optimal pricing and underwriting, automating policy admin, streamlining claims adjusting workflows etc. We are rethinking everything from first principles. If you think you have ideas about how things should be done and are able to build them, this is the role for you.

We’re well-funded and backed by top investors, with the resources to build aggressively, but we operate like a small, high-output team. We don’t optimize for titles or org charts. We care about people who take ownership, move quickly, and want to build something massive.

What you’ll work on

• Building core platform systems: taking MVPs to production-grade, handling complex state machines and edge cases where mistakes have real financial consequences
• Building data ingestion pipelines - parsing messy real-world formats from third-party systems and turning them into clean, reliable data
• Building automated AI systems that have serious business impacts and consequences
• Shipping across multiple products - features often span multiple user types and systems
• Designing integrations with external platforms - mapping third‑party APIs and building monitoring to catch issues early

What you won’t deal with

• Ticket factories — engineers are involved in product decisions, not just execution
• Slow shipping — we ship daily and prioritize user feedback
• Siloed roles — you’ll work across backend, frontend, and infrastructure
• Process for the sake of process — no story points, no unnecessary ceremonies

You should have

• Strong experience building web applications across the stack
• Ability to work across technologies (Python, Golang, TS, Nextjs, infra, postgres, etc.)
• Comfort with integration-heavy systems and external APIs
• Experience owning production systems end-to-end, including debugging and incident response
• Excellent at utilizing AI to speed up your own workflows
• Ability to question why things are the way they are

Bonus

• Experience in insurance, fintech, or other regulated domains
• Familiarity with AWS (S3, SQS, ECS) and Docker in production environments

About the interview

Please reach out giving examples of end to end projects that you have built previously, and what you would like to build on the team. Then we schedule a quick 30 min interview. If everything seems aligned then you come in person for a work assessment, where you get to work on a test project similar to what the job would actually look like. Then we give out offers and start asap.
