About the role

This is a senior technical security role for our product and platform. You'll set the standards and guardrails that shape how we build, and you'll spend a lot of your time working directly with engineers to help them build securely. We want someone who gets stuck in and helps teams solve problems, not someone who sits apart and signs things off. Security has to be designed into what we build, not added afterwards. You'll own our secure development standards, run threat modelling on the work that carries the most risk, and set the direction for how we handle cloud security, identity, vulnerability management and data protection. A big part of the job is lifting the security knowledge of the engineering and product teams so that sensible decisions get made in-team every day, without everything having to route through you.

You'll work across engineering, platform and the wider security team, and your focus will be the technical side of security across the whole product lifecycle, from how we design and build through to how we protect data and control access as we grow.

Responsibilities

• Give engineers practical, hands-on security advice throughout the development lifecycle, so they can ship quickly and safely.
• Own our secure development and secure coding standards, and coordinate penetration testing across the delivery lifecycle.
• Run threat modelling on the highest-risk work, and set up the approach and training so teams can do their own.
• Set the security standards and guardrails for our cloud environment, covering secure configuration, access and encryption, and support the people who put them into practice.
• Decide how we judge vulnerability severity and remediation priority, and set the standards that engineering works to.
• Design how we manage identity and privileged access, including strong authentication and controlled elevation of access.
• Lead our approach to data security, including classification, keeping customer data properly separated, and choosing and rolling out data-loss-prevention tooling.
• Bring deep security judgement to assessments of higher-risk suppliers.

About you

• Plenty of experience in a senior or principal security architecture or application security role, ideally in a cloud-based software company that has grown quickly.
• Strong hands-on cloud security background, covering secure configuration, access and identity, encryption, guardrails and security considerations for modern cloud and serverless architecture.
• Solid grounding in secure software development, including threat modelling, secure coding, awareness of common application security risks such as the OWASP Top 10, automated security testing and running penetration tests.
• Practical experience across vulnerability management, identity and privileged access, data security, and software supply-chain practices such as SBOMs.
• A pragmatic approach that helps engineers move quickly, rather than slowing them down.
• Clear communicator who can win over technical and non-technical colleagues and turn security risk into practical decisions.
• Willing to explore where AI can strengthen how we build and secure our products, and pragmatic about applying it where it genuinely fits.

We especially want to hear from you if you have:

• Worked in InsurTech, FinTech or another regulated industry.
• Helped build a security function or set of practices from an early stage.
• Built security into a modern engineering delivery setup.
• Worked on software that serves many customers from shared infrastructure, and the data-separation questions that come with it.
• Relevant certifications such as CISSP, CCSP or an AWS security qualification, though we care more about what you can do than what you hold.
• Spent time training and coaching engineers on security.
