About Stack AI

Stack AI is democratizing access to Large Language Models through a user-friendly no-code platform integrating the best AI models (OpenAI, Anthropic, Google), data sources (OneDrive, Google Drive, Notion), and SaaS tools. We're backed by Y Combinator and Gradient Ventures, with thousands of users and hundreds of paying customers including public companies and unicorns.

The Role

We're looking for a senior frontend engineer who is incredible at execution. This is not about building flashy new features from scratch—it's about optimizing, refining, and incrementally improving what we've already built. You'll work closely with our Product Design pod to turn detailed visual specs into clean, production-ready code.

Main Mission: Remove the bottleneck in our Product Design pod by taking ownership of incremental UX/UI improvements to existing features and code.

What You'll Do
  • Optimize and refine existing frontend code and features

  • Implement incremental UX/UI improvements from detailed design specs (no design skills required)

  • Work autonomously with minimal code review needed—your code should be clean enough that our other Front Enders can trust it blindfolded

  • Collaborate with Product Designers, Design Engineers, and Front End Engineers on execution

  • Focus on high-impact improvements that elevate our product quality and user experience

  • Clean up and improve legacy code

What We're Looking For

Must-haves:

  • Exceptional code quality: Clean, maintainable, trustworthy code that requires minimal review

  • Strong execution: You ship fast and ship well

  • Senior-level experience: 5+ years with React, TypeScript, Next.js, and modern frontend stack

  • Accountability: You own your decisions and respond when needed

  • Autonomy: You can own features end-to-end without hand-holding

  • Pragmatism: You are willing to engage with detail-oriented and iterative work that is essential to the product's success

  • Technical excellence: Someone who can teach us, not someone we have to teach

Nice-to-haves:

  • Experience with Tailwind CSS

  • Understanding of UI fundamentals (but design skills are NOT required)

  • Experience cleaning up and optimizing existing codebases

  • Comfort working across the stack when needed

Our Tech Stack

React, Next.js, TypeScript, Tailwind CSS, TanstackQuery

What We Value
  • High bar: We only hire people who wow us technically—someone better than us

  • Trust: We've learned that even "boring tasks" require exceptional engineers, because poor execution takes more time to review than to do right the first time

  • Execution over excitement: You're motivated by doing excellent work, not just working on the newest, shiniest features

Why This Role Matters

The Product Design pod has ambitious plans in the roadmap, and we need a frontend engineer who can execute flawlessly to keep pace. You'll be critical to ensuring our product quality and velocity.

This role description captures the team's emphasis on exceptional technical quality, execution, and pragmatism over design skills or working on only the most exciting features.
