Job Description


The team is missioned to build infrastructures, platforms and technologies, as well as to support cross-functional teams to protect our users, products and infrastructures. In this team you'll have a unique opportunity to have first-hand exposure to the strategy of the company in key security initiatives, especially in building scalable and secure-by-design systems and solutions. Our challenges are not your regular day-to-day technical problems; you'll be part of a team that's developing new solutions to new challenges of a kind not previously addressed by big tech. It's working fast, at scale, and we're making a difference.

  • The primary responsibility of this role is to organize and conduct goal-based red team exercises, coordinate external red team engagements, collaborate with the blue team to conduct ongoing purple team exercises based on evolving threats and identify control gaps, and produce high-quality, actionable reporting and recommendations on those activities.
  • Perform penetration testing and realistic security exercises to simulate various attack scenarios, to test and improve our detection and response capabilities, and to identify weaknesses in our infrastructure and products.
  • Collaborate closely with other parts of the security team and product teams to design defense-in-depth controls that limit attackers' ability and improve our security postures.
  • Monitor and analyze emerging cyber threats, vulnerabilities, and exploits relevant to our infrastructure and products.
  • Bring insight into all aspects of modern security issues to our products and rapidly developing prototypes for mitigations.


  • 3+ years of experience in ethical hacking, vulnerability research, exploit development, penetration testing or being a member of a red team.
  • Advanced knowledge and understanding in various disciplines: web application security, mobile app security, network security, operating system internals and hardening, applied cryptography, cloud computing. You're expected to be an expert in at least one of these areas.
  • Strong problem-solving skills and excellent debugging / troubleshooting skills.
  • Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or other relevant majors.
