We are looking for a Senior Security Engineer with 3–10 years of experience to be the first dedicated security hire and build the security program from the ground up.

  • Conducting threat modeling to identify how client could be attacked and proactively preventing those attacks
  • Performing deep security reviews and hardening of the Python proxy, APIs, and authentication systems
  • Building the security program end-to-end – standing up processes, tooling, and secure development practices across application and CI/CD layers
  • Driving resolution of critical vulnerabilities by partnering directly with engineers to fix issues, not just find them
  • Owning security across IT, cloud infrastructure, and the software supply chain as the sole security engineer
  • 3 - 10 years of experience: in security engineering, with focus on application security
  • Visa Sponsorship Details: Open to visa transfers (e.g. OPT, H1B transfers)
  • Remote work policy US-based working US hours
