- Solid grasp of modern stacks: CI/CD pipelines, containers, Kubernetes, and at least one major cloud provider
- Hands-on use of LLMs / AI models for security tasks, with the judgment to measure where they help and where they fail
- Comfort with large datasets (SQL, BigQuery, or similar) t o drive research and measure detection accuracy
- Takes research ideas from prototype to production with minimal guidance
- Clear written communication - can explain a complex attack path to engineers and product managers
- M.Sc. in Computer Science, Cyber Security, or a related field
Nice to have:
- Published research, CVEs, conference talks, or a bug bounty track record
