## About the role

We are looking for a Security Software Engineer who ships. You will own the research and development of offensive capabilities that power Sybil, working end-to-end from vulnerability discovery through production delivery. This is a role for someone who finds their own problems, builds their own solutions, and raises the bar for everyone around them.

## What they're looking for

- 4 or more years of software engineering experience, with meaningful time in offensive security contexts
- Hands-on experience finding vulnerabilities across a variety of targets, whether through red teaming, bug bounty, CTF, or production pentesting
- Strong Python fundamentals: you have designed, deployed, and maintained backend systems in production
- Comfort with modern JavaScript and React, you can own a feature across the full stack
- Experience building with LLMs or generative AI tools, including prompt engineering and integrating model outputs into real workflows
- A builder's instinct: you default to figuring things out, not waiting for direction
