Location: Portsmouth Broad Oak and occasional travel to other BAE Systems sites. We offer a range of hybrid and flexible working arrangements - please speak to your recruiter about the options for this particular role

Salary: Up to £64,000 depending on skills and experience

Who we are:

Join BAE Systems and you’ll be part of something bigger. As a valued member of our global colleague network, you’ll bring your unique skills and perspectives to help pioneer progress and protect what matters most. You’ll be trusted to play your part in delivering the advanced, technology-led defence, aerospace and security solutions of tomorrow, shaping a safer future, for all of us.

From the depths of the ocean, to the far reaches of space, there’s no limit to where a career at BAE Systems could take you.

Job Description:

As a Principal Product Security Engineer, you will lead the application of information assurance, cyber security, and physical security principles throughout the Secure by Design engineering lifecycle. This includes influencing security requirements from concept and design through development, verification, acceptance, and in-service support.

Working closely with the System Design Authority (SDA), product development teams, and external assessors, you will provide expert security guidance to ensure that security requirements are effectively integrated into product designs and aligned with regulatory, customer, and organisational security standards. You will be responsible for defining, developing, and maintaining security requirements, ensuring that security considerations are embedded in technical solutions from the outset.

A key aspect of the role will be conducting threat modelling, security risk assessments, and vulnerability analysis to identify potential attack vectors early in the design lifecycle. You will advise engineering teams on the selection and implementation of appropriate security controls and mitigation strategies to reduce risk and support security assurance objectives.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
