Superhuman is building the AI-native future of work: a family of products people and companies rely on to think, write, and get things done faster. We ship AI features and agents at a pace that makes security one of the most interesting problems in the building, and we're looking for a Product Security Engineer to help us solve it. Your job won't be to slow us down; it will be to make moving fast the safe default. You will be building the identity model, guardrails, and secure-by-default platform that lets our engineers and AI systems operate boldly. You'll work on bleeding-edge AI and product security problems: securing AI agents and applications, automating KTLO and toil work away, and empowering our engineers to build quickly and securely because the safe path is the default path. As a Product Security Engineer, you will:

Collaborate with Product Engineering teams throughout the SDLC, creating Threat Models, conducting Design Reviews, Secure Code Reviews, and manual testing to identify vulnerabilities.

Develop and implement end-to-end security solutions to mitigate risks across our product suite.

Help drive improvements across our Product Security tooling, automation, and bug bounty program.

Experiment with and develop AI-based tools to enable the Security team to move even faster.

Be the voice of our customers, actively engaging stakeholders across engineering teams, communicating security risks and trade-offs while keeping customer data secure.
