Flow is the iterative requirements and verification platform built for hardware teams to ship complex systems faster. Backed by Sequoia and Air Street.
About the role
Our customers in defense, aerospace and more trust us with sensitive systems requirements. That means security is a first-order part of the product, so we’re looking for a Staff Software Engineer to own it. This is our first dedicated security hire, so you'll define the security architecture, harden the platform, and build out the compliance posture. Since LLMs and agentic workflows sit at the center of what we do, you'll also lead how we secure them. Found on 1752vc Careers, the job board for startup and VC roles.
