Join a SME Defence & Government company as a Cleared Full Stack Developer in Leeds.
Defence programmes run on software that has to work first time, every time.
There's no room for shortcuts when the systems you build support national security work, and that pressure attracts developers who want their code to matter.
This SME has spent years building a reputation in Defence & Government circles, and it's now growing its engineering team to keep pace with demand.
The business sits in that sweet spot between agility and structure.
Defined roles, clear processes, but still small enough that your work gets noticed.
As a Cleared Full Stack Developer, you'll be part of a team that treats security clearance as a baseline, not a badge.
Here's what you'll be doing: Design and build full stack features across secure, mission-critical applications for Defence & Government clients Write clean, maintainable code on both front end and back end, following security-by-design principles throughout Work within accredited environments, handling sensitive data in line with government security standards Collaborate with architects, testers and project leads to deliver releases on tight, non-negotiable deadlines Troubleshoot and resolve issues across the stack, from database queries to UI bugs Contribute to code reviews and help junior developers get up to speed on the codebase Here are the skills you'll need: Active SC clearance, or eligibility to obtain it (this is non-negotiable for the role) Solid experience with modern front end and back end frameworks (React, Node.
js, .
NET or similar) A working understanding of secure coding practices and how they apply in regulated environments Comfortable owning a feature end to end, from database schema through to deployed interface Clear communicator who can explain technical trade-offs to non-technical stakeholders Experience working within structured, process-driven delivery teams Key perks and benefits: Salary of £46,500 to £66,000, depending on experience Private medical insurance and pension contribution Annual leave with flexible working built around office-based collaboration in Leeds Bonus schemes tied to company and individual performance Genuine progression path within a growing SME, not a faceless corporate ladder Why pursue a career in Defence & Government?
Defence & Government work offers something rare: job security paired with technical challenge.
Budgets are long-term, the problems are genuinely hard, and cleared developers remain in short supply across the UK.
Leeds has quietly become a hub for this kind of work, with a growing cluster of Defence & Government employers putting down roots in the city.
