Software Engineer - Nullify

Black Nova Venture Capital; Sydney; On-site; AUD 120,000 - 180,000; Full time

Job summary

Black Nova Venture Capital in Sydney is seeking a security-minded engineer to own detection and remediation pipelines, building scalable services in Go and Python. You will work on real distributed-systems challenges and contribute to the product with solid, well-tested code.

You bring strong fundamentals in Go and Python, experience with production distributed systems, a preference for correct code, and curiosity about security.

Qualifications

• Strong fundamentals in Go and Python.
• Experience with production distributed systems — queues, state machines, idempotency, failure modes.
• A preference for simple, correct code over clever abstractions.
• Curiosity about security, even if it's not your background yet.

Responsibilities

• Build and extend detection and remediation pipelines across our security services, in Go and Python.
• Work on genuinely hard distributed-systems problems: deterministic PR check runs, idempotent scan orchestration, fair queuing across thousands of customer repos.
• Ship code that's held to a real bar — typed, tested, reviewed, and deployed by commit sha with no shortcuts.
• Work close to the product: what you build shows as a fix in a real engineer's PR within days, not quarters.

Job description

Every detection service we ship — SAST, DAST, SCA, secrets, cloud posture — 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 safe to merge.

What You'll Do

• Build and extend detection and remediation pipelines across our security services, in Go and Python.
• Work on genuinely hard distributed-systems problems: deterministic PR check runs, idempotent scan orchestration, fair queuing across thousands of customer repos.
• Ship code that's held to a real bar — typed, tested, reviewed, and deployed by commit sha with no shortcuts.
• Work close to the product: what you build shows as a fix in a real engineer's PR within days, not quarters.

What You Bring

• Strong fundamentals in Go and or …
• Experience with production distributed systems — queues, state machines, idempotency, failure modes.
• A preference for simple, correct code over clever abstractions.
• Curiosity about security, even if it's not your background yet.
