Job description

Step into this DV Cleared Developer role and build something that matters in Defence & Government.

A fast-growing technology company in the Defence & Government space is hiring a DV Cleared Developer to join its London team. The work here touches national security infrastructure, so clearance isn't a box-ticking exercise. It's the price of entry to genuinely consequential engineering, and the small, flat team behind it moves quickly and expects its developers to do the same.

Here's what you'll be doing:

Design and build secure software systems for government and defence clients, working across the full stack where needed

Write clean, well-tested code that meets strict security and compliance standards from day one

Work directly with technical leads and clients to translate operational requirements into working software

Review code, mentor junior engineers, and help shape technical decisions as the team grows

Troubleshoot and resolve issues in live secure environments, often under time pressure

Contribute to architecture decisions on systems that handle sensitive data

Here are the skills you'll need:

Active DV clearance (essential) or current eligibility with a willingness to undergo vetting

Solid commercial experience as a developer, ideally 3+ years, with strong fundamentals in at least one modern language

Comfort working in secure, air-gapped, or otherwise restricted environments

Good judgement under ambiguity. Startup environments don't hand you a detailed spec for everything

Clear communication skills, since you'll be explaining technical trade-offs to non-technical stakeholders

A genuine interest in defence and government technology, not just the clearance premium

Key perks and benefits:

Salary of £53,000 to £77,500, depending on experience

Equity in a growing company, not just a salary line

Flexible working hours around a core London office day

Learning and development budget to keep your skills current

A flat structure where your input actually changes what gets built

Why pursue a career in Defence & Government?

Defence & Government technology spending in the UK keeps climbing, and London remains its centre of gravity. DV cleared professionals are in short supply relative to demand, which means strong pay, real job security, and a faster route into senior technical roles than most other sectors offer. Few fields let you see your work matter at national scale.
