Responsibilities

Build Frontier AI Systems
Define architectural patterns for training, deploying, and operating AI at scale—your decisions shape how the entire team approaches model development
Design agent systems that decompose tasks, invoke tools (compilers, debuggers, test runners), manage state, and recover from failures across multi-hour autonomous workflows
Architect RL pipelines with execution-based rewards (RLVR), process reward models, and self-improvement loops for code generation
Translate cutting-edge research into production: read papers, understand the math, build systems that work at scale
Create evaluation frameworks that measure what actually matters—not benchmark leaderboards, but iteration efficiency, cost, reliability, and generalization to unseen codebases
Understand why SWE-Bench scores don't tell the whole story and define what does
Elevate the team: mentor on ML fundamentals, debugging techniques, and the craft of building reliable AI systems
Lead design reviews ensuring training pipelines are robust and models are production-ready
Align AI capabilities with product needs while maintaining technical integrity

Qualification

Required

8+ years building AI that shipped
End-to-end model development: Data pipelines → architecture design → distributed training → production serving. You've done it all
Frontier systems expertise: Transformers, large-scale training, RLHF, execution-based RL, or agent training—at a depth where you can modify and improve them
Production operations: Inference optimization, model monitoring, and keeping AI reliable under real traffic
Engineering excellence: Code that other engineers can maintain, debug, and extend
Technical leadership: Establishing standards and making architectural decisions that last

Preferred

Trained large models and understand the distributed systems challenges
Built novel architectures or training methods that improved on prior art
Debugged training instabilities or model failures that stumped everyone else
Built agent orchestration: multi-step reasoning, tool invocation, state management across long-horizon tasks
Worked on code understanding at repo scale—retrieval, indexing, context management, or agent memory systems
Read full papers (not summaries) and implemented several from scratch
Open-source work or public implementations demonstrating depth
Research backgrounds welcome—PhDs, research leads, or anyone who built models behind published work
Non-traditional paths from physics, math, or quantitative fields
Learning velocity over tenure: 8 years learning fast beats 15 years coasting
Shipped systems over published papers

Benefits

A company that is always growing, changing, and innovating.
Real career opportunities.
Work colleagues that are as smart, hard-working, and driven as you.
Disrupting the status quo is in our DNA.
We ask 'why' a lot.
