Grow your career in the new frontier.
Join us as we build the hard but fair gyms that frontier labs trust when they need reliable model improvement.
Work at the edge of the frontier.
Build the evals that will create AGI.
Collinear works with frontier model teams to identify important failure surfaces and build the artifacts needed to move past them. You will work across research and engineering to turn ambiguous problems into task suites, evaluations, and training programs that hold up under scrutiny.
Task suites
Realistic tasks calibrated to expose where today's strongest models still fail.
Benchmarks
Reproducible evaluations that reveal capability gaps, not just a leaderboard number.
Environments
Runnable tools, repositories, and workflows that preserve the complexity of real work.
Verification
Rubrics, graders, and programmatic checks that measure outcomes instead of plausibility.
A small team with a high bar.
We keep the distance between an idea and its impact short. That means real ownership, direct collaboration, and a shared commitment to work that is impactful, innovative, and technically interesting.
-
01
Stay close to the failure.
Start with observed model behavior. Understand what broke, why it matters, and what evidence would demonstrate improvement.
-
02
Own the outcome.
Move from ambiguity to a finished result. Ask questions early, unblock yourself, and own the consequences of your decisions.
-
03
Make the work inspectable.
Clear reasoning, reproducible methods, and bounded claims are how we earn trust with each other and with research partners.
-
04
Raise the bar together.
We challenge ideas directly, share context freely, and care more about arriving at the right answer than defending the first one.
Your work advances research at Collinear and across the AI frontier.
You will work closely with founders, research scientists, and engineering leads. The artifact you build this week will shape the next evaluations, training runs, and benchmark releases for cutting-edge AI models.
