Security Software Engineer

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.

You will work closely with our engineering and product teams to translate offensive security intuition into repeatable, AI-driven capabilities. If you thrive in ambiguity, move fast, and want your work to have a direct impact on a product customers rely on, this is the role for you.

• Research and develop offensive agentic capabilities that become core Sybil features
• Hunt for real vulnerabilities across a range of target environments and translate what you find into repeatable, automated techniques
• Build and ship end-to-end customer-facing features: from research spike to production deployment
• Design and implement LLM-powered tooling that extends Sybil's reach and depth across attack surfaces
