Job Description
You will join as a core engineer building an AI engine that prioritizes critical security threats. Working alongside a founder from HackerOne, you will bridge the gap between automated scanning and real‑world attacker logic, developing sophisticated ML pipelines and agentic AI features to help organizations defend themselves at scale.
Why this role is remarkable
- Work directly with a founder who led Hacker R&D at HackerOne and managed programs for the UK Ministry of Defence and FTSE 100 companies.
- Massive ownership in a small team of 6, backed by 6 Degrees Capital and advisors from DeepMind, Cisco, and 1Password.
- Opportunity to shape an AI‑native product in a $17B+ market, moving beyond simple API wrappers to genuine model training and evaluation.
What You Will Do
- Build and maintain full‑stack features using a Python/Prefect backend and React frontend, handling everything from authorization to production debugging.
- Own the ML lifecycle, including training models, building evaluation pipelines, and shipping agentic AI features to automate vulnerability analysis.
- Collaborate directly with customers to identify pain points, rapidly prototype solutions, and ship impactful security tools in a fast‑paced environment.
The Ideal Candidate
- Has 2‑6 years of professional engineering experience with strong Python fundamentals and a proven track record of shipping production software.
- Possesses genuine depth in Machine Learning, understanding model training and evaluation techniques rather than just consuming third‑party APIs.
- Exhibits a growth mindset and curiosity, thriving in high‑autonomy startup environments and valuing engineering craft over rigid processes.
