Key Responsibilities

- Define the hardware and system-level architecture for advanced UAV platforms.
- Integrate avionics, sensors, communications, propulsion, power distribution, flight controls and payload systems.
- Develop clear system architecture, wiring and interconnection diagrams.
- Define electrical connections, signal routing and power-distribution requirements.
- Collaborate with electrical, mechanical, aerospace and software engineers to establish technical requirements and interface specifications.
- Support the physical assembly and integration of aircraft components and subsystems.
- Investigate and resolve component compatibility, wiring and integration issues.
- Create detailed work instructions for assembly, integration and testing activities.
- Document tooling requirements, safety precautions and quality checkpoints.
- Develop system-level test plans and validation procedures.
- Conduct functional, integration and environmental testing.
- Analyse test results and recommend design improvements.
- Support ground and flight-testing campaigns for UAV platforms.
- Prepare documentation required for flight approvals, operational clearances and regulatory submissions.
- Liaise with regulatory authorities and other stakeholders where required.




- Maintain accurate system specifications, architecture documents, wiring diagrams, test reports and technical records.
- Support the preparation of user manuals and technical documentation.
