Software Security Internship - Defence & Security – 2026 summer placement

This internship focuses on advanced defence and security technology development. The role is suited to students at undergraduate, master’s, or PhD level with a strong technical grounding in software security, cyber technologies, and embedded or distributed systems. The placement will last 12 weeks. Successful candidates should be available to start their placement between May and October 2026. There is no deadline for this role, as we recruit on a rolling basis. Once the position is filled, we will close the advert. We encourage you to apply as soon as possible.

What you’ll be doing:

• Contribute to research and development of secure systems across defence and security domains.
• Support the creation of novel security technologies, including areas such as threat landscaping, post-quantum cryptography, privacy-enhancing technologies, and trusted execution approaches.
• Investigate and prototype embedded and distributed software for constrained, safety-critical, or adversarial environments.
• Perform threat analysis, security architecture reviews, and experimental validation of new techniques.
• Collaborate with multidisciplinary teams covering software, electronics, RF, AI, autonomy, and communications.
• Participate in full lifecycle development activities, including design, implementation, testing, and documentation.

What you can bring:

• Currently studying in Computer Science, Engineering, Mathematics, Physics, or a related discipline.
• A background in software or hardware engineering, with a demonstrable interest in cybersecurity research.
• Knowledge of one or more programming languages such as Python, C/C++, Rust, Go, or similar.
• The ability to undertake technical investigations and communicate findings clearly.
• Eligibility to obtain UK Security Clearance.

Desirable experience:

• Experience in embedded software development or hardware–software interactions.
• Experience in security for IoT, robotics, autonomy, or smart infrastructure.
• An understanding of regulatory or assurance environments for security-critical systems.

Some projects at Cambridge Consultants are subject to security restrictions. This role requires you to obtain a Security Check level security clearance. You must be able to work in the UK without restrictions in accordance with UK National Law and be prepared to successfully undertake an appropriate level of UK National Security Vetting according to UK Government National Security Vetting criteria.

Working Environment:

A successful intern will work within the Defence and Security business unit, engaging with experienced engineers and researchers on high-impact client and internal R&D projects. Work may involve both on-site and laboratory-based activities.
