Product Manager

About Arondite

Arondite builds software that helps organisations use autonomy, data, and AI at scale. The company provides operators with the core tools they need to coordinate platforms and capabilities, so they can make mission-critical decisions faster than those who oppose them.

The business exists to help the UK and its allies stay ahead of threats to their values and way of life. Its technology is built for harsh, demanding environments and is used by highly exacting operators. The team works alongside customers and brings technical expertise wherever it is needed.

You would be joining at a key stage of growth, with ambitious plans for the long term and support from well-known investors such as Index Ventures. The team is made up of highly capable engineers who enjoy solving difficult, high-impact problems and delivering strong results. In this role, you would work with equally strong colleagues on some of the most important problems in the world.

From day one, you would have real ownership and freedom. There is no traditional corporate progression path here; instead, you would directly shape the product’s design, direction, and functionality. The company hires exceptional people and gives them a high degree of autonomy.

Role overview

This position owns a critical area of the product. It is closer to running a small startup than working inside a standard product team: you will need to work through unclear problems, make decisive calls, and carry work from discovery through launch.

You will build a deep understanding of complex user workflows, including how the software is used with deployed engineering teams and operational customers. You will partner closely with Strategy and Partnerships, Engineering, and the Deployed team to decide which capabilities should be generic, where specialised workflows are required, and how to turn that knowledge into simple, effective product choices.

The work affects mission-critical environments and aligns with UK and NATO national security priorities. You will need to work quickly, think carefully, and stay close to users and internal teams so the product solves the right problems in the right way.

Key responsibilities

• Own the outcomes and overall success of a major part of the product.
• Work through a broad set of users and stakeholders, and turn their feedback into clear direction.
• Create a practical and transparent method for prioritising work when facing uncertainty in a B2G context.
• Partner with Engineering and Design to deliver powerful but simple features that can be adapted for many types of users.
• Promote high technical standards and crisp communication across the team.
• Collaborate with Product, Engineering, and Deployed teams to anticipate needs and help shape the long-term roadmap for Cobalt.
• Ensure the product delivers an excellent user experience.

Requirements

• Hands-on experience owning products, platforms, data models, or core infrastructure areas in a top-tier product environment.
• Ability to gather signals from users, stakeholders, and engineers, then convert them into clear and manageable work items.
• Skill in building, explaining, and refining a prioritisation framework.
• Strong curiosity about the defence sector and its technology landscape.
• A founder-style mindset with comfort in ambiguity and responsibility for broad objectives.
• Strong technical understanding and systems thinking, including comfort with schemas, APIs, and architecture trade-offs.
• Excellent communication and stakeholder management skills, with the ability to align cross-functional teams around a clear direction.
• Willingness to travel to customer locations to understand how they work.
• Nice to have: experience creating leverage through product operations automations.
• Nice to have: experience in defence or in sectors that involve geospatial workflows.
• Nice to have: experience in a world-class product organisation.
• Nice to have: experience founding a company.

Deployed work

Roles that involve deployment at Arondite require close collaboration with customers at UK sites and sometimes overseas. This may mean spending 1 to 4 days per week away from the office on a regular basis, or travelling abroad for up to 2 to 3 weeks every few months. The company tries to stay flexible with resourcing so personal circumstances can be considered.

Right to work

All applicants must already have the legal right to work in the UK at the time they apply.

Security clearance

Because the company works closely with defence customers, this position requires either an existing clearance or a willingness to complete UK security vetting at Security Check (SC) level or higher. This usually means having lived continuously in the UK for at least 5 years.

Working style

The company is building a collaborative, engineering-led culture and prefers the office to be an enjoyable, comfortable place to work. While occasional work from home is acceptable, the default expectation is to work in person. Travel to customers may also be needed, depending on the role.

Application process

• Submit your CV along with initial screening questions.
• Have an introductory Teams conversation lasting 30 to 45 minutes.
• Attend an in-person technical interview lasting 1 to 2 hours.
• Complete a final interview with one of the founders, lasting 30 minutes.

Benefits

• Competitive base pay.
• Generous EMI share options in a well-funded startup that is growing quickly.
• Employer pension contribution of 7%.
• Free meals provided in the office every day.
• Private medical and dental cover, with optional dependent coverage.
• Cycle-to-work scheme.
• Relocation assistance.
• Access to the resources, equipment, and training needed to do the job to a world-class standard.
• Opportunity to learn from exceptional colleagues with strong academic backgrounds and deep sector expertise.
