Exigyn is hiring a Senior Full-Stack Engineer to help build the first agentic AI application for FP&A in life sciences. You’ll work closely with the founders to ship quickly, solve real customer problems, and own product decisions from idea to release.
Exigyn is an agentic AI framework that replaces spreadsheets and rigid SaaS platforms with custom, automated solutions for life sciences finance and operations.
We’re looking for senior builders who are comfortable with ambiguity, high ownership, and fast iteration.
Build product features across the stack, from workflows and interfaces to APIs and data systems.
Work directly with founders, users, and design to turn messy problems into simple product experiences.
Help shape engineering standards, architecture, and how we ship as a small team.
Ship customer-facing features end to end.
Design clean, reliable application architecture that can grow with the product.
Debug issues quickly and improve performance, quality, and developer velocity.
Contribute to product thinking, not just implementation.
Strong experience building and shipping software in startup or high-ownership environments.
Comfort moving across frontend, backend, and data layers as needed.
Good product judgment and a bias toward action.
Clear communication and the ability to work through ambiguity.
We value builders who can show real work, sound judgment, and strong ownership.
We care more about what you’ve built and how you think than polished interview answers.
