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.

• Has 5+ years of relevant experience in securing applications at scale.

• Experience working at each touchpoint in a secure SDLC: threat modeling, design reviews, secure code reviews, and web app pentesting.

• Familiarity with the standard Product Security tool suite: SAST, DAST, and SCA.

• Experience with using AI to solve Security challenges at scale.

• Software engineering or programming experience in at least one language, such as Java, Python, JavaScript, or Go.

• Experience managing vulnerability disclosure programs or conducting security research on bug bounty platforms such as HackerOne or Bugcrowd.

• The ability to think like an adversary to identify risk, and then build like an engineer to mitigate those risks.

• Has a demonstrated ability to work independently with minimal guidance, proactively manages tasks and priorities across multiple projects, analyzes and executes work efficiently, collaborates effectively with cross-functional teams, and thrives in fast-paced, results-driven environments.
