You will be embedded with software engineers, reverse engineers, and vulnerability researchers, hardening the infrastructure, supply chains and pipelines on while guiding their secure development.

The work includes guiding and reviewing build integrity and supply chain review to threat modeling our own tooling. If you have ever looked at a supply chain & development environment and immediately started listing the ways you would secure it, this is the job. You will be the person the team trusts to tell them when something is a real risk and when it is just noise

As an AI Security Integration Engineer on our team, you will bridge the gap between traditional security infrastructure and modern programmatic defense. You will guide the secure development and evolution of software vulnerability tooling. Your primary focus will be working with the development team to maintainmaintaining the tool security posture utilizing continuous ATO. review workflows and pipelines by leveraging Python, assessing robust API integrations, maintained exploring AI/LLM orchestration to rapidly scale threat detection and response capabilities.
