Job Description What you’ll be doing: As a Senior Security Engineer - Product Security & Architecture, you'll embed security into the heart of how we design and build products. This isn't a traditional high-level architecture review role - you're a builder who partners deeply with engineering and product teams on secure architecture patterns and automated tooling to enable a secure-by-design mindset. As a technical SME, you will play a hands-on role in shifting security left and scaling secure design best practice across the organization. Partner with engineering and product teams across the business to embed security into product design, architecture and the software development lifecycle. Guide engineering teams through the maturation of application security best practice. Contribute to the development of security standards, guidelines and self-service resources that enable engineering teams to move fast and stay secure. Perform threat modelling and secure architecture reviews to provide actionable, developer-friendly guidance that empowers teams to make good security decisions early on. Develop tooling, including AI-powered agents, to enable a secure-by-design mindset through the design, build and release phases of the product development lifecycle Mentor engineers and foster a security-first mindset across product and engineering disciplines. Qualifications What we’re looking for: Demonstrated experience working directly with software engineering teams to enable a security mindset in product design and application development and architecture. Hands-on experience building automation workflows and/or AI agents to scale security design and architecture practices - you are a builder first. Strong understanding of application security and secure software development lifecycle practices. Experience performing threat modelling and architecture reviews in a modern cloud-native environment. Familiarity with infrastructure-as-code security and cloud security posture management. Strong collaboration and communication skills, with the ability to translate complex security concepts into accessible, actionable guidance for non-security audiences. Aligned with our values: we change the game, we own it, we step in, we are curious, we don't take ourselves too seriously. We know not everyone will meet every requirement, and that’s okay. If you’re excited about the role and believe you can make a difference, we’d love to hear from you. Additional Information A few other things we want you to know...
