Tech Stack

  • Backend: Kotlin 1.7.20, AWS, GraphQL (it would be nice if you were familiar with this but it’s not a deal breaker), Postgres, RabbitMQ, Docker, Kubernetes
  • Frontend: React & React Native, TypeScript, MobX, Redux, Stylus and SASS
  • Other: We build our Kotlin projects using Gradle and GitHub Actions, deploying to production as soon as we finish a feature. We use JUnit Jupiter, Kotest and TestContainers for automated testing.

What you’ll be doing

  • Secure the Pipeline: Integrate and automate SAST, DAST, and SCA tooling directly into our CI/CD pipelines to catch vulnerabilities before they reach production.
  • Harden the Product: Act as a Subject Matter Expert (SME) assisting engineers with the remediation of security vulnerabilities and bugs.
  • Safeguard AI: Design and implement security guardrails for AI-assisted development and LLM integrations, ensuring data privacy and preventing prompt injection or model leakage.
  • Threat Modelling: Partner with Product and Engineering teams to conduct threat modelling sessions for new features before they are built.
  • Security Architecture: Act as a consultant for infrastructure and application design, ensuring our AWS/GCP Kubernetes environments remain hardened.
  • Security Culture: Cultivate a Secure Development guild to level up our developers' secure coding skills.

What we’re looking for

  • Pragmatism: You understand the difference between partnering with Engineering and security being a blocker of progress.
  • Communication: You can translate a complex vulnerability into a business risk for a Product Manager and a technical fix for an Engineer.
  • AppSec Subject Matter Expertise: You have a strong understanding of critical security risks in applications, are able to identify them in code, and provide recommendations of how to remediate.
  • Cloud Native: Strong experience securing AWS/GCP environments and containerised workloads.
  • AI ready: You understand the unique risks of AI and have experience securing AI-driven workflows.
