Job Description

n

Nullify is building the post-human product security program - one harness that drives product security work to closure by continuously allocating AI capacity toward the highest-impact product security work.

n

From detection through to triage, patch generation, assignment and escalation, the harness shares one pipeline shape and one bar for correctness. You'll own real slices of that system, from taint-analysis code graphs to the distributed logic that decides whether a PR is secure to merge.

What you'll do n

n
- Build and extend detection and remediation pipelines across our security services, in Go and Python.
n
- Work on genuinely hard distributed-systems problems: deterministic PR check runs, idempotent scan orchestration, fair queuing across thousands of customer repos.
n




- Ship code that's held to a real bar - typed, tested, reviewed, and deployed by commit sha with no shortcuts.
n
- Work close to the product: what you build shows up as a fix in a real engineer's PR within days, not quarters.
n

What you bring nn
- Strong fundamentals in Go and/or Python, and the judgment to know when to reach for which.
n
- Experience with production distributed systems - queues, state machines, idempotency, failure modes.
n
- A preference for simple, correct code over clever abstractions.
n
- Curiosity about security, even if it's not your background yet.
