hn-hiring

Come work on my team! (We’re hiring lots of engineers right now, but I’m biased toward my own group today.)
Factory builds software development agents that accelerate the world's largest enterprise engineering teams. We're helping customers including Nvidia, Adobe, Adyen, Klarna, and Ernst & Young turn their engineering organizations into autonomous development systems — shipping code, reviewing PRs, running tests, and deploying continuously.
We're seeking a talented Security Engineer to join our team. In this role, you will play a critical role in developing and maintaining the security foundation of our platform. You will conduct in-depth code reviews, implement security best practices, and influence the overall security strategy. Your expertise in TypeScript, Python, Kubernetes, CI/CD, and terraform orchestration will be crucial in identifying and mitigating potential security vulnerabilities.
