As part of our ongoing mission to mature Trainline's security capabilities, you'll help protect the digital channels that power billions of pounds in annual ticket sales, keeping our systems secure, resilient and ready for what's next.
In this role as the Senior Product Security Engineer, you will...
- Define and own the product security roadmap, aligning priorities with business goals and influencing engineering leadership to embed security into how we design, build and deploy products.
- Establish and own the application security vulnerability management process, from triage and prioritisation through to remediation tracking, setting and reporting metrics such as mean time to remediate (MTTR) by severity and security testing coverage to give leadership clear visibility of risk.
- Work with teams across the business to carry out threat modelling for our web, mobile and API services, identifying risks and putting effective countermeasures in place.
- Assess the security posture of our applications and APIs through code reviews and static and dynamic security testing (SAST/DAST), and manage third-party penetration tests, from scoping with engineering teams and architects through to tracking remediation.
- Strengthen the security of our iOS and Android apps and the APIs that power them, covering areas such as authentication and authorisation, secure data storage, API gateway controls and protection against abuse and automated attacks.
- Implement, maintain and automate the security tools that support safe development and operations, from vulnerability scanning through to application security posture management (ASPM), and partner with engineering teams to fix vulnerabilities in ways that prevent them recurring.
- Build secure coding and deployment knowledge across the organisation through training and mentoring, including helping to establish and grow a security champions programme within our engineering teams.
- Ensure our product security practices align with relevant frameworks and standards, such as OWASP, NIST, ISO 27001, GDPR and PCI DSS, supporting compliance and audit efforts while monitoring emerging threats and finding ways to strengthen our resilience.
We'd love to hear from you if you have...
- Significant experience identifying, assessing and mitigating security risks across application design, code and deployed products, including setting up and running application security vulnerability management processes and reporting.
- Experience shaping and delivering a product or application security roadmap, with the confidence to influence engineering leaders and use metrics to demonstrate progress and risk reduction.
- Experience securing mobile applications and APIs, including testing iOS and Android apps and applying secure approaches to authentication and authorisation, such as OAuth 2.0 and OpenID Connect.
- Hands-on experience with security testing tools such as SAST, DAST and vulnerability scanning solutions, ideally including mobile app security testing and API security testing tools.
- Practical experience with threat modelling and security reviews, as well as scoping and managing third-party penetration tests in partnership with engineering teams and architects.
- A strong grasp of secure coding practices and experience embedding security into software development workflows, including implementing technical controls and driving automation within CI/CD pipelines, ideally across cloud-native, containerised and infrastructure as code (IaC) environments.
- Familiarity with industry standards and frameworks such as OWASP (ideally including the Mobile Application Security Verification Standard and API Security Top 10), PCI DSS, ISO 27001 and GDPR.
It would also be helpful if you have experience setting up or growing a security champions programme, running risk assessments, or a working knowledge of regulatory compliance standards.
