Lead Security 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 Engineer in our Cyber practice, you'll be the most senior security engineering voice on client engagements, setting technical direction for how organisations design, build, and defend secure systems. 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 is engineered into everyday work - from threat modelling and architecture at design time to hardened, monitored systems in production. You'll build trusted relationships with client engineering leads, platform teams, and senior stakeholders, translating between deep technical decisions and the trade-offs senior leaders need to understand. You'll bring the judgement to know when a heavyweight security architecture is warranted and when a lighter-weight, faster-moving approach serves the engagement better. At Lead level, your impact extends beyond the immediate team. You'll establish security engineering standards and reference architectures across engagements, grow the technical capability of the people around you — colleagues and client engineers alike — and contribute to how Made Tech's Cyber practice develops as a community. If you'd rather build the paved road than police the off-road, who treat security as an engineering discipline rather than a compliance exercise, and who cares about leaving client teams genuinely stronger than you found them, this role is for you.
