Software Engineer - Summer 2026 Intern

Arondite is a defence technology company building the foundational software and AI to power the autonomous age. Our aim is to revolutionise the way organisations collaborate with sensors, robots and autonomous systems and use the data they generate. We are driven by our determination to help defend our collective democratic values and by our strong belief that an elite group of engineers can make a big difference. We are ambitious, well-funded and building for the long-term.

You will join Arondite at a pivotal moment in the company’s journey. Our company is being built by exceptional engineers - people who find high-impact and technically challenging work engaging and exciting, and who consistently deliver outsized impact. You will collaborate with other brilliant minds to solve some of the world’s hardest and most important problems.

You will have ownership and autonomy from Day One. There is no corporate ladder at Arondite. From your first day, you will directly influence the design, functionality, and direction of Arondite’s product offering. We hire the best people and give them extremely high levels of autonomy; the sky is the limit for an individual with the right ambition.

If you are motivated by our mission and if you want to be part of a growing team of outstanding people, then we want to hear from you.

Arondite is looking for an ambitious and versatile Software Engineering Intern to work in our growing software engineering team for the summer of 2026. This internship is a hands-on opportunity to work on real-world projects, contribute to meaningful software development, and learn from experienced engineers in a fast-paced environment.

You should have:

• Will be entering the final year of an undergraduate degree in Computer Science or another technical subject in September 2026
• Are an ambitious builder with extremely strong software engineering skills
• Care about the ethical defence of sovereign democracies
• Want to work closely with cutting-edge AI and integrate with autonomous systems (e.g., drones)
• Want to see your work used with impact in the real-world (affecting atoms, not just bits)
• Have programming experience in at least one server-side programming language (e.g., Python, C++, Java, or Rust)

Ideally, you would also have:

• Experience with Git or other version control systems
• Personal or academic projects you’re proud of

Note: We want Arondite to bring together individuals from diverse backgrounds and perspectives. We don't expect everyone to have experience across each of these areas. Please apply even if you only partially fulfil this list.

Right to Work

We require that all candidates have an existing Right to Work in the UK at the time of application.

Security clearance

We believe in working closely with defence customers. As a result, this role will require the individual to hold a clearance or be willing to undergo UK security vetting to Security Check (SC) or above. This normally requires having continuous residency in the UK for at least 5 years.

Office vs Hybrid working

We are focused on building a positive, collaborative engineering-driven culture. We therefore believe in making the office a friendly, comfortable and fun place to be, and we try to work from the office where possible. Of course, there are times when it makes sense for you to work from home and that's OK. You may also need to travel to visit customers, depending on your role. But in general you should only apply to join Arondite if you're excited to come into the office and work in person by default.

Application process

Generally, our interview process is comprised of the following stages:

1. CV submission with initial questions
2. Introductory Teams call (30 mins)
3. In-person technical interview (1-1.5 hours)

• Highly competitive base salary
• 7% employer pension contribution
• Free breakfast and lunch every day; free pizza and beers weekly
• Access to any resources, equipment and training that you need to do your job in a world-class way
• The opportunity to work with and learn from exceptional colleagues with excellent academic experience and deep industry knowledge
