Lead Security Assurance Engineer

Made Tech helps UK government and public sector organisations build better digital services — and security is central to that mission. As a Lead Security Assurance Engineer in our Cyber practice, you'll be the most senior security assurance voice on client engagements, setting the technical direction for how organisations identify, assess, and respond to security risk. You'll work across complex government programmes where the stakes are real: services that affect citizens, systems that hold sensitive data, and teams that need to move quickly without cutting corners. This isn't a role where you sit at the edge of delivery reviewing outputs. You'll be embedded in multidisciplinary teams, shaping how security assurance is woven into everyday engineering work — from threat modelling at design time to control testing in production. You'll build trusted relationships with client security teams, senior stakeholders, and government security communities, translating between technical findings and the risk decisions that senior leaders need to make. You'll bring the judgement to know when a full ISO 27001 governance programme is appropriate and when a lighter-weight approach serves the engagement better. At Lead level, your impact extends beyond the immediate team. You'll establish assurance frameworks and standards across engagements, grow the security capability of the people around you — colleagues and client staff alike — and contribute to how Made Tech's Cyber practice develops as a community. If you're someone who builds capability rather than gatekeeping decisions, who treats security as an engineering concern rather than a compliance exercise, and who cares about leaving client teams genuinely stronger than you found them, this role is for you.
