  • Expertise in cloud platform security, especially securing multi-cloud networks and infrastructure and designing cloud-agnostic systems.
  • Familiarity with container security, orchestration security, authentication, and authorization.
  • Familiarity with internet and web security fundamentals, including web application firewalls, Transport Layer Security, public key infrastructure, and Domain Name System security.
  • Proficiency developing in at least one programming language and using Infrastructure as Code tooling.
  • Prior experience in a safety-related technical role, such as infrastructure security, security operations, threat modeling and prioritization, or digital forensics and incident response.
  • Knowledge of operating system internals and security mechanisms.
  • Knowledge of common networking protocols.
  • Ability to give and process constructive feedback.
  • Ability to work independently and collaboratively.
  • Flexibility to adjust to the dynamic nature of a startup.
  • Ability to take a risk-based approach to building security controls, balancing security expertise and broad technical skillsets with practical, usable solutions.

Responsibilities

  • Design and build security controls across cloud platforms, operating systems, Kubernetes, networks, and continuous integration and continuous delivery systems to defend against sophisticated adversaries and insider threats.
  • Improve Tailscale's security properties by identifying opportunities for security and privacy features, bug fixes, and defense-in-depth, and implementing them across the codebase.
  • Audit Tailscale infrastructure for technical security weaknesses, identify mitigations or solutions, and drive them toward resolution.
  • Support engineering decisions with threat modeling, security analysis, and expertise.
  • Spend 25–50% of the role writing software, rather than focusing purely on operational or governance security responsibilities.
  • Act as a subject matter expert during security incidents, focusing on infrastructure-level containment and remediation.

About the Company

Tailscale

Connects devices through encrypted private networks

Tailscale connects people, servers, and applications through encrypted private networks, giving businesses and individuals access to resources across clouds and physical locations. Its software uses WireGuard to encrypt traffic and connects devices directly where network conditions allow, with encrypted relay paths for harder connections. Administrators use identity services and access policies to manage who reaches each resource, without exposing every system to the public internet. The company sells business subscriptions priced by seats, with additional controls for larger teams and a free plan for personal use. Founded in 2019, Tailscale is headquartered in Toronto, Ontario, Canada.
