Office Manager

About this role

WHY WE EXIST: Swarmer develops software that makes drones autonomous and allows them to operate together, in large, coordinated teams—no pilots needed. Our technology has been battle-tested in Ukraine—the world’s most intense proving ground for drone warfare. In March 2026, we became the first Ukrainian defense startup to go public on NASDAQ, following a $15M Series A—the largest investment in a Ukrainian defense tech company since the start of the war.

Working at Swarmer means operating at the intersection of engineering rigor and frontline reality. The problems and environments are complex, and the stakes are very real. We built this software to enable democratic nations to defend themselves. If you are motivated by building resilient systems that matter and by seeing the direct impact of your work, you’ll find purpose here. WHO WE'RE LOOKING FOR: We're looking for a proactive, people-focused Office Manager to run our growing Lviv office.

You'll keep the office running smoothly every day and make it a place people enjoy coming to: well organised, well stocked, safe and secure, and full of community. You'll work closely with HR, Finance, Operations, and our Security teams as well as site and leadership. You are someone who anticipates problems before they happen and takes initiative without waiting to be asked. WHAT YOU'LL DO: - Keep the office stocked, clean, and ready: supplies, meeting rooms, desk allocation, seating plans, and office moves as the team grows, fixing issues before they affect the team.

- Own the daily lunch programme for the whole office, from menu planning, headcount and dietary requirements to vendor selection, quality control and staying within budget. - Manage office access, keys, badges, visitors and deliveries together with Security, following Swarmer's security and visitor procedures. - Manage relationships with cleaners, maintenance contractors, caterers and other suppliers: set service expectations, source and compare quotes, and work with Finance on contracts and payments.

- Assist the supply chain team in managing the hardware storage - Handle petty cash, utilities and office bills accurately and on time, with monthly reconciliation, correct coding and early flagging of budget variances. - Assist the HR team with administrative duties and other support activities on an as-needed basis. - Build a connected office culture through team lunches, celebrations, and social initiatives, and help leadership run all-hands meetings, offsites, and gatherings, including welcoming colleagues visiting from other Swarmer locations.
