We’re looking for an Application Security Engineer to join our Information Security team, working closely with Engineering, Infrastructure and Architecture to help us build and maintain secure applications at scale.
This is a hands-on role focused on improving the security of our software development lifecycle. You’ll work collaboratively with engineering teams across multiple products, helping to identify and reduce risk while enabling teams to deliver at pace.
As a member of a globally distributed team, you’ll be comfortable working independently, taking ownership of your work, and proactively engaging with colleagues across regions.
What you will do
- Partner with engineering teams to review application designs and implementations, identifying security risks and working collaboratively to address them
- Contribute to and evolve our Secure SDLC processes, ensuring security is embedded into how we build and deliver software
- Perform application security reviews across a range of technologies and services
- Support vulnerability management activities, including triage, prioritisation and remediation guidance
- Manage and triage CVEs impacting our environments, working with teams to drive timely resolution
- Contribute to the security of our CI/CD pipelines, helping to ensure controls are effective and practical
- Build, maintain and improve secure base Docker images for use across engineering teams
- Manage and improve dependency update processes and tools, helping teams stay up to date securely
- Work with engineers to investigate and remediate security issues, providing clear and actionable guidance
- Advocate for security improvements, helping teams understand risk and make informed decisions
- Contribute to and improve our security documentation, ensuring guidance is clear, accurate and accessible for engineering teams
- Contribute to continuous improvement of our tools, processes and ways of working
What are we looking for?
- 2+ years experience working in application security or a software engineering role with a strong security focus
- Strong understanding of common application security risks and how they apply in real-world systems
- Experience reviewing application code, architecture or designs from a security perspective
- Hands-on experience working with Linux-based systems and Docker
- Experience supporting or integrating security into CI/CD pipelines
- Familiarity with vulnerability management processes, including CVE triage and remediation workflows
- Ability to work independently and manage your own priorities in a distributed team environment
- Strong communication skills, with the ability to work effectively with engineers and non-security stakeholders
- A collaborative mindset, with a focus on enabling teams rather than acting as a gatekeeper
Nice to have:
- Experience with Python and related frameworks (e.g. Django, FastAPI)
- Experience with modern frontend technologies (e.g. JavaScript, TypeScript, React)
- Familiarity with dependency management tooling (e.g. Renovate)
- Experience securing containerised or cloud-based applications
How We Work
- We work as partners to engineering teams, embedding security into everyday development rather than adding it at the end
- We focus on pragmatic, risk-based decisions that balance security with delivery needs
