From the original posting
About the Role
We're looking for a Full Stack Software Engineer to own features end-to-end across Arena's platform — from understanding the problem, through designing and building the solution, to shipping it, measuring its impact, and iterating. This is a hands-on IC role for someone who writes code every day, cares deeply about what happens after launch, and is excited to shape how people interact with cutting-edge AI.
You’ll
Own features from technical scoping through deployment and post-launch iteration — not just build them, but make sure they work
Design and extend schemas, APIs, and business logic to support new product capabilities
Ship high-quality product code across the stack
Incorporate real user feedback — from data, direct user contact, or your own product instincts — to improve what you've shipped
Work closely with ML researchers to turn research services to production, making them consumable for product development
Collaborate across design, product, and engineering to figure out what to build, not just how
Identify and advocate for improvements to development, testing, and deployment practices
You’ll have
3+ years of experience in software engineering, with a focus on enterprise or developer facing product development
Experience building user-facing web applications spanning frontend, backend/API, and database — in any stack. You understand the request lifecycle across layers
Clear, concise communication — you explain technical decisions well, distinguish your work from the team's, and proactively share context
Evidence of shipping and iterating — you can describe the full arc of a feature you owned: problem, solution, code, what happened after launch, and what you'd change now
A product engineering identity — you care about whether the thing you built actually worked for users, not just whether the code was clean
Genuine curiosity about AI evaluation and Arena's mission — you've looked at the product and can articulate why this domain matters to you
Bonus Points
Familiarity with our stack: NextJS, React, TypeScript, Tailwind, ShadCN, HonoJS, Postgres, Vitest
Experience with Supabase or Vercel's AI SDK
You've shipped without PM or design support — determined what to build by talking to users or looking at data
