Staff Product Security Engineer
We are seeking a Staff Product Security Engineer to help build secure products, platforms, and development practices at scale. In this senior individual contributor role, you will partner closely with software engineering, product, infrastructure, and privacy teams to identify and reduce security risk throughout the product lifecycle. You will influence technical direction, establish pragmatic security standards, and help teams deliver resilient services without compromising customer experience or delivery speed.
Your responsibilities will include defining and advancing secure-by-design practices, reviewing system architectures and high-risk product changes, and providing expert guidance on threat modelling, abuse-case analysis, authentication, authorisation, data protection, and secure communications. You will develop and maintain security tooling, reusable libraries, reference architectures, and automated controls that enable engineering teams to prevent and detect vulnerabilities earlier. You will also lead complex security investigations, support vulnerability remediation, contribute to incident response, and communicate risk, priorities, and recommendations clearly to both technical and non-technical stakeholders. As a technical leader, you will mentor engineers, raise security awareness, and help shape the organisation’s product security strategy.
The successful candidate will bring substantial experience in product or application security, with a strong background in secure software development and modern cloud-based systems. You should be comfortable working across multiple programming languages and reviewing code, designs, APIs, distributed systems, and infrastructure. Experience with threat modelling methodologies, common application vulnerabilities, software supply-chain security, security testing, and DevSecOps practices is expected. You will be an effective collaborator who can influence without direct authority, balance security with business objectives, and operate confidently in ambiguous environments. Strong written and verbal communication skills, sound judgement, curiosity, and a practical approach to solving complex problems are essential. Experience leading cross-functional security initiatives or contributing to industry standards and open-source security projects would be advantageous.
