At Lendurai, we enable unmanned aerial vehicles (UAVs) to operate independently of global navigation satellite systems and radio control, using computer vision and machine learning. We partner with multiple UAV manufacturers to deliver cost effective capabilities to public sector and defence customers. Our core team has substantial experience in aerospace engineering and developing computer vision applications across Europe, including at companies like Bolt (EE), Open Cosmos (UK), and Starship Technologies (EE).

What you will be doing

As a UAV Field Operations Engineer you will own the day-to-day flight-test loop in Tallinn: plan, fly, measure, iterate, and showcase our tech to end-users in defence, public sector and OEM partners across Estonia.

Execute manual and automated test flights.
Flash experimental firmware and software builds; maintain fleet configuration control.
Diagnose and fix basic mechanical and electrical problems on the field.
Maintain testing units for development and demo events.
Capture, parse and visualise telemetry/video; feed insights to product and software engineering teams.

Improve test velocity, tooling and process through continuous experimentation.
Train end users to use Lendurai products effectively.
Plan and fly demo days for defence customers; provide light account-management follow-up.
