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.
