Senior Product Security Engineer
We are seeking a Senior Product Security Engineer to help build secure, resilient products from design through deployment. In this role, you will partner closely with software engineering, infrastructure, product, and development teams to embed security throughout the product lifecycle. You will assess architectural designs, identify threats and vulnerabilities, define practical security controls, and provide guidance that enables teams to deliver high-quality products securely and efficiently.
Your responsibilities will include leading threat modelling and security reviews, developing secure design patterns, and advising on application, API, cloud, and infrastructure security. You will conduct and oversee vulnerability assessments, penetration testing, code reviews, and security testing, ensuring findings are prioritised and remediated effectively. You will also contribute to security standards, engineering policies, and technical documentation; support incident investigations; improve security automation within CI/CD pipelines; and help establish meaningful metrics to measure product security maturity. As a senior member of the team, you will mentor engineers, promote security awareness, and influence technical decisions across the organisation.
The successful candidate will bring substantial experience in product, application, or software security, with strong knowledge of secure software development practices, threat modelling methodologies, vulnerability management, and security testing techniques. Experience securing cloud environments, APIs, distributed systems, and modern development pipelines is highly desirable. You should be comfortable reading and reviewing code in at least one programming language, collaborating with technical and non-technical stakeholders, and translating complex security risks into clear, actionable recommendations. Relevant professional certifications are beneficial but not essential. We value curiosity, sound judgement, strong communication skills, and a pragmatic approach to balancing security, usability, and delivery goals.
