## About the Role

* Hands-on product or application security experience, embedding security practices across a modern software development lifecycle

 * Ability to review code and communicate security issues clearly to developers, primarily within a C# ecosystem, with exposure to Java or Python

 * Strong knowledge of the OWASP Top 10 and practical mitigation patterns

 * Experience implementing or improving SAST/DAST processes: tool tuning, triage workflows, and reducing signal to noise

 * Working understanding of cloud and container security fundamentals, ideally with AWS and Docker

## Description

This role sits within our Product Security function, embedded across multiple product and engineering teams rather than a single one. You'll define and operationalise security requirements throughout the SDLC, from initial design through to release, with real authority to make independent security calls rather than deferring to what a scanner tells you. It's a role built on trust: teams will come to you for guidance, and the judgement you bring to triage, threat modelling, and governance decisions will shape how security actually gets done here.

 * Partner directly with engineering and product teams to define and operationalise security requirements across the full SDLC

 * Own or co-own application security governance: secure-by-default standards, patterns, guardrails, and risk exceptions

 * Lead threat modelling for new features and architectural changes, turning findings into practical engineering work

 * Drive SAST/DAST adoption and quality, from tool tuning to severity calibration and developer-facing triage guidance

 * Support product teams adopting AI, including LLMs, SLMs, and MCP, giving you visibility into work most security roles wouldn't touch
