Drone Engineer - Software

About the company

Swarmer is a Ukrainian technology company developing AI systems that coordinate military drone swarms.

About this role

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 hands-on UAV/Drones Preflight Specialist who enjoys getting hardware flight-ready — flashing firmware, configuring modules, running bench tests and test flights, and tracking down faults. Here, your work doesn't stay in the lab: the drones you prepare are deployed in some of the most demanding conditions in the world. WHAT YOU’LL DO: - Perform visual and technical quality control of UAV assembly and electronic component integration – after in-house production or repair, as well as after purchasing UAVs from third-party manufacturers. - Install, flash, and configure firmware and software on the flight controller and additional UAV modules. - Run comprehensive testing, including initial activation, bench tests, and initial test flights, to verify correct UAV operation and configuration. - Configure and verify connectivity between the drone and flight planning systems or ground control stations. - Diagnose and resolve faults at the software and component-integration level, and perform scheduled maintenance on UAVs and related equipment. - Create and maintain clear technical documentation, including setup instructions for various UAV system components, test reports, and user manuals. WHAT WE NEED: - Solid knowledge of UAV components and systems. - Strong soldering skills and hands-on experience with electronic components. - Familiarity with UAV firmware and tools like Betaflight, ArduPilot, Mission Planner, and QGroundControl. - Ability to read and interpret technical diagrams and schematics. - Working knowledge of Linux – comfortable in the terminal, with SSH, and basic commands. - Understanding of complex IT systems with multilayer communication. - English at B1 level or higher. WOULD BE AN ADVANTAGE: - Proven experience assembling, configuring, and maintaining UAVs (FPV, commercial, or military). - Experience with 3D printing and custom details design. - Basic programming skills (Python, Bash, or C++). WHAT YOU’LL GET: - A dynamic environment with a unique opportunity to directly influence and see the impact of your work. - Hands-on work with drone hardware that's actively shaping the field, not just theory. - A tight engineering team with short feedback loops and real ownership of your builds. - Competitive salary and a comprehensive benefits package HOW’S THE HIRING PROCESS GOING: ✔️Recruiter Screen → ✔️Technical Interview → ✔️Test Day → ✔️Skip-level Interview → ✔️Offer Please note that, as a leading defense tech company, we take operations security seriously and may need to perform additional background checks as part of our hiring process.
