What will I be doing? 🚀

  • Define & drive our technical strategy through influencing security engineering team roadmaps, as well as leading & delivering impactful projects.
  • Do hands-on engineering work at every level of our stack, building software components that our engineering teams can use to tackle common software vulnerabilities and raise the security bar across our core infrastructure.
  • Design improvements to the security architecture around our production environment, applying the principle of least privilege to improve our identity and access management for customers, users and applications.
  • Assess the security of planned features and applications as well as our core infrastructure, partnering with the relevant teams to identify and mitigate risks prior to release.
  • Act as the lead in our response to security incidents, working as part of a cross-functional incident response team to rapidly contain and mitigate security incidents.
  • Partner with other engineers in the information security group, providing guidance and technical mentorship for others to help them grow and do the best work of their careers.

What skills do I need? 📖

You need to have professional experience which includes some or all of the following areas of security engineering:

  • Applying security processes as part of the Secure Software Development Lifecycle (e.g. threat modelling, security architecture reviews)
  • Knowledge of common web-based vulnerabilities (e.g. CSRF, XSS) and the mechanisms to defend against them (e.g. HSTS, CSP, TLS etc)
  • Building controls which implement security standards/frameworks, such as authentication (e.g. SAML), authorization (e.g. Oauth, Oso) or applied cryptography
  • Leveraging automation to secure cloud infrastructure, e.g. implementing identity & access controls, managing secrets, segmenting networks.

In addition:

  • You have deep knowledge of a high-level programming language (e.g. Ruby, Python etc.). Note that the language doesn’t have to be one that we use here!
  • You have proficiency and prior experience in writing & delivering software in a production environment.
