Software Engineer - Summer 2027 Intern

Arondite enables organisations to wield autonomy, data and AI at scale. We equip operators with the foundational software to orchestrate their mix of platforms and capabilities, and then take mission-critical decisions faster than their adversaries.

We exist to ensure the UK and its allies out-think, out-pace and out-adapt those who seek to threaten our values and way of life. Our technology is designed for deployment in the world’s most austere environments, and is relied upon by the world’s most demanding operators. We deploy alongside them, bringing our technical expertise wherever it is needed.

You will join Arondite at a pivotal moment in the company’s journey. We are ambitious, building for the long-term and backed by globally renowned investors including Index Ventures (Anthropic, Wiz, Figma, Revolut). Our company is being built by exceptional people; people who find high-tempo and 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 during your time with us. 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 an outstanding team, 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 2027. 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.

• Will be entering the final year of an undergraduate degree in Computer Science or another technical subject in September 2027
• 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)

• 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.

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

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.

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.

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

1. CV submission with initial questions
2. Introductory Teams call with coding test (30-45 mins)
3. In-person technical interview (1-1.5 hours)

• Highly competitive salary
• 7% employer pension contribution
• Free meals in the office every day
• Access to any resources, equipment and training that you need to do your job in a world-class way
