- Owner and improver of reliability, performance, and safety across existing Rust codebases
- Identify bottlenecks, edge cases, and failure modes in complex systems—then implement scalable, elegant fixes
- Collaborate closely with data, research, and engineering teams to accelerate model training and evaluation
- Lead synchronous system design reviews and drive architectural decisions with clarity and confidence
