Project Manager - Defence Virtual Simulation

We are a well-established team based in Farnborough (UK) at OneArc, developing world-leading military simulations for major NATO powers and their allies. We constantly seek ways to advance the industry using the latest technologies and trends (such as whole-world simulations, motion tracking, VR, and AR).

We believe in saving lives through simulations.

Your job will be totally different from what you expect

We give you freedom and responsibility to do things well, support you, train you, and teach you. We have a relaxed environment where we aim not to limit our staff with too many regulations. We trust you.

We offer a wide variety of work and a crunch-free environment due to our products being developed as a continuous service.

Also, you will not constantly do the same things over and over again.

About the role

You will be the boots-on-the-ground face of our flagship Defence Virtual Simulation (DVS) programme for the UK Ministry of Defence (UK MOD) — travelling regularly to units across the country to support, train, and build relationships with the people actually using our software.

This is a frontline, relationship-first role first, and a project management role second. You'll work with personnel at every level — from a corporal needing basic IT assistance through to a brigadier overseeing a complex training exercise — and represent OneArc confidently in front of a room, whether that's a customer course, a conference, or a symposium.

Over your first year, and with our support, you'll grow into providing PM support and managing smaller UK-based projects — including time and backing to work towards a PMQ or PRINCE2 qualification if you don't already hold one.

There's no expectation you arrive with deep project management experience; what matters is that you're excited to get out on the road, learn how different parts of the armed forces work, and help them get the most out of our software.

Our business has a worthy cause — the work we do has an actual impact on making the world a safer place. You will serve as a key point of contact between UK MOD units, internal teams, and industry partners, helping drive adoption of our software, supporting customer satisfaction, organising community events, and supporting sales opportunities.

Do you think you have what it takes?

• Ideally, you've served in the military, or you have industry experience within a defence-focused organisation (for example, another defence company involved in service delivery) — either way, you understand how different parts of the armed forces operate and how they might use simulation and training software. Exposure across multiple service branches is a strong plus.
• You're comfortable working with people at every level of the military — from a corporal needing basic IT assistance through to a brigadier overseeing a complex training exercise.
• You have strong public speaking skills and are confident standing up in front of a customer course, conference, or symposium to talk about simulation and training.
• You're early in your career rather than in a senior role — for example, not long out of the Army, or around five years into industry — and you're excited to travel to units across the country to support them and learn their use cases.
• You proactively take on complex challenges and work to get them fixed, aiming for long-term operational success.
• You take ownership of your work, adapt to changing requirements, and are self-motivated and highly organised.
• You hold, or are eligible to obtain, UK security clearance.
• Formal project management experience isn't required from day one — but you should have worked in or alongside projects in some capacity. Over your first year, you'll build towards providing PM support and managing smaller UK-based projects, with support to complete a PMQ (APM) or PRINCE2 Practitioner qualification along the way if needed.
• You should be located in Southern England - Hybrid working with the requirement to attend customer sites across the UK, as well as the OneArc Farnborough office when required.

Nice to have

• Hands-on Virtual Battlespace (VBS) experience — e.g. Administrator course completion and regular active usage.
• ITIL qualification.
• In-depth knowledge of computer hardware, software, and software development lifecycles.
• Familiarity with military simulation, interoperability standards, and military R&D.
• Detailed knowledge of the broader VBS product suite.
• High proficiency in Microsoft Excel and dedicated project planning software.

What you get?

We're not about all the hard work and no fun. Our office culture is relaxed, collaborative, and mission-driven. We do our best to look after our people.

Below is a snapshot of the perks you'll get if you work with us:

• A diverse, challenging, yet fun working life — travelling to and supporting one of the UK MOD's most critical simulation programmes.
• The opportunity to work on top-of-the-line, cutting-edge products employed by military organisations globally.
• The ability to build the OneArc brand across the armed forces, influence programme direction, and directly impact capability rollout.
• Structured growth into a project management remit over your first year, backed by qualification support.
• Work with and learn from talented colleagues in a high-visibility, customer-facing role.
• Full-time employment with a competitive salary.
• Hybrid working on office days: 3 days office, 2 days home option (in addition to regular UK travel).
• 25 days vacation per year + 8 bank holidays.
• 5% company pension contribution matching scheme.
• Death in Service Life Assurance benefit (3x annual salary).
• Free gym access scheme.
• Office refreshments including filtered water, coffee, tea, and fruit.

We don't offer just a job. We want to give you the opportunity to grow and advance the simulation market.
