- Integrate debugging, instrumentation, fuzzing, crash analysis, and related research tools into automated or researcher-directed workflows.
- Develop backend services, REST APIs, data pipelines, and user interfaces for accessible and traceable research capabilities.
- Establish evaluations measuring finding validity, reproducibility, false-positive rates, and the usefulness of AI-assisted analysis.
- Troubleshoot complex issues across application code, AI integrations, research tooling, and execution environments while improving performance, reliability, and observability.
- Lead design and code reviews, document technical decisions, mentor engineers, and communicate progress, risks, and tradeoffs to stakeholders.
Requirements
- Demonstrated experience independently designing, implementing, testing, and delivering complex software features or subsystems.
