- Build tools that make model training repeatable, agent-driven, and help engineers evaluate AI systems.
- Evaluate changes against real attack patterns and investigate missed attacks and false positives.
- Improve system reliability and performance within latency and cost limits.
- Write tested, readable code and contribute to technical designs and code reviews.
- Own well-defined features from design through release and monitor their behavior in production.
Must Haves
- A bachelor's degree in Computer Science, Software Engineering, Information Systems, or a related engineering field.
