You're really into code. You enjoy complex systems, pushing the boundaries of performance, and building solid, reliable solutions. You're not just writing code to get the job done—you’re focused on making it better, faster, and stronger with every line. And you know that great code isn’t just smart - it’s secure.

What You’ll Do:

Code. Review. Improve. Repeat.

The engine is the heart of everything we do. It powers tens of thousands of security scans every week and delivers an interface for thousands of security checks that demand speed, precision, and rock-solid reliability.

As part of the team, you’ll write code that fuels this engine - collaborating with passionate engineers to evolve our next-gen web crawler, browser automation, HTTP network injection systems, and v8-based security checks.
