Arondite is a defence-tech startup building Cobalt, a mission-critical operating system for connected defence. We seek a design-led teammate to shape the product vision and user experience in demanding contexts.
As the third design member, you will influence visual direction, collaborate with engineers and users, and push AI-enabled design processes, including prototyping with Cursor & Claude Code. Office-first, with home days possible.
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 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.
Unlike most defence tech, design is a first-class citizen at Arondite. To accomplish our vision, we believe it's crucial our software is unmistakable in mission-critical scenarios, governed by careful design decisions and rigorous safeguarding along the way. As the third design member, you’ll have a direct impact on the future of human-machine teaming in this industry, alongside strong influence on the product vision, visual direction, and design culture at Arondite.
You’ll be working on our flagship product, Cobalt. Cobalt is an operating system for connected defence. It provides users with a wide range of capabilities, from geospatial terrain analysis and annotation to complex mission planning, where users have to coordinate the actions of humans and autonomous devices working in the same environment. The work you’ll be doing here will be in entirely new and unexplored problem spaces.
Your work will have direct relevance to mission-critical environments and to the national security priorities of the UK and NATO. You will be expected to move quickly, think rigorously, and collaborate closely with users and internal teams to ensure Arondite builds software that solves the right problems in the right way.

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 are focused on building a positive, collaborative engineering-driven culture. As a result, we 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. 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. For most of us, this usually means at least 3 days a week.
