Product Engineer

Rubric Labs is a small team of founder-level engineers with our own research lab. We build with teams like Gumloop, Graphite, and E2B, and write up what we learn on the blog.

This is our first full-time engineering hire outside the founding team. You'll work inside client teams and own builds end to end, from the first scoping call to production.

What you'll do

• Scope projects with clients and turn ideas into plans
• Build interfaces, APIs, data models, and agent loops
• Ship AI features to production and test them with evals
• Work directly with client founders and engineering teams
• Write about what you build and learn

What we're looking for

• Several years shipping production software, with work you can point to
• Comfort owning a project without a spec or a manager checking in
• Taste in interfaces. You notice when spacing, motion, or copy is off
• Clear writing. Most client communication happens in docs and threads
• Experience building with LLMs

Benefits

• Competitive health benefits
• Equipment and home-office budget of $1000
• Three weeks of paid vacation
• Annual team trips
• $1000 per month discretionary token spend

How to apply

Email hello@rubriclabs.com with your resume and links to two or three things you've built. Tell us which one you're proudest of and why.

We care about proof of work more than credentials. The quality of what you've built, and what you've worked on, weighs more than where you studied or worked.

We review applications on a rolling basis.
