Software Security Engineer

Location: Bristol

Salary: Up to £74,000 + bonus (21%), pension, flexible working

Most software security roles ask you to protect things that don't really matter.

This one's different.

You'd be working across some of the most sophisticated defence products in the world, guiding security from concept through to in-service support, not just running assessments at the end of a project when it's too late to change anything meaningful.

The role sits inside a multi-disciplined software engineering team, and your job is to be the person who shapes how security is thought about, not just checked. That means influencing architecture decisions, coding standards, technology selection, and development methodology, working with engineers who take security seriously because the stakes demand it.

What the work looks like:

You'll conduct security assessments and threat analyses, develop mitigation strategies, and provide technical guidance to software and project teams. You'll have a say in which technologies and frameworks get adopted, and you'll help build the processes and documentation that make security repeatable across the product lifecycle. SC clearance is required, with willingness to progress to DV.

What they're looking for:

Experience in software security within defence, aerospace, automotive, or telecoms. You'll understand industry security standards and best practices, and you're comfortable leading technically as well as collaborating across disciplines. A STEM degree or equivalent experience, and an interest in emerging technologies and the security challenges they bring.

What's on offer:

Salary circa £74k, bonus up to 21%, pension up to 14% combined contribution, hybrid working, and a benefits package that includes enhanced parental leave and excellent on-site facilities.

If you're the kind of engineer who wants your security expertise to actually count, this is worth a conversation.

Where to Advertise Space Jobs in the UK (2026 Guide)

Where to advertise space jobs UK in 2026: the specialist boards, agency channels and community routes that reach satellite, propulsion and launch talent. The candidate pool spans satellite engineers, propulsion specialists, mission analysts, ground segment software developers, space systems architects and commercial space professionals — a highly specific multidisciplinary community that general job boards are poorly equipped to reach. The strongest space candidates are often embedded in ESA programmes, academic research groups, UK Space Agency-funded projects or established primes, and move between roles through sector-specific networks, industry bodies and conference communities rather than mainstream platforms. This guide, published by UKSpaceJobs.co.uk, covers where to advertise space industry roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

Space Jobs UK 2026: What to Expect Over the Next 3 Years

Space Jobs UK 2026: roles, salaries and the UK space sector hiring trends shaping satellites, launch, Earth observation and space data careers. The UK space sector is in the middle of something that feels genuinely historic. A combination of government commitment, private capital, and technological progress has transformed Britain's position in the global space economy from a capable but secondary player into a nation with serious sovereign ambitions — and a jobs market that is expanding to match them. This is not the space industry of previous generations, defined by a small number of government agencies, a handful of prime contractors, and career pathways accessible only to a narrow band of elite engineers and scientists. The new space economy is broader, faster-moving, and more commercially driven than anything the sector has previously seen. Satellite manufacturing has been democratised by small sat technology. Launch is becoming domestic. Space data is flowing into applications across agriculture, insurance, climate monitoring, maritime, and defence at a scale that is creating entirely new categories of commercial hiring. And the defence and national security dimensions of space have elevated the sector's strategic importance to a degree that is driving sustained public investment in the talent pipeline. For job seekers, the UK space jobs market of 2026 represents an opportunity that is both more accessible and more technically demanding than at any previous point. The candidates who will thrive over the next three years are those who understand where the sector is heading — which programmes are moving from development into operation, which technologies are defining the architecture of modern space systems, and how the definition of a space career is expanding well beyond the spacecraft engineering core toward a much wider ecosystem of roles across the full space value chain. This article breaks down what the UK space jobs market is likely to look like through to 2028 — covering the titles emerging right now, the technologies driving employer demand, the skills that will matter most, and how to position your career at the leading edge of one of the most exciting sectors in the UK economy.
