About The Role

We are seeking a Senior Systems Engineer to join the team leading the development of the Zephyr High-Altitude Platform Station (HAPS). In this role, you will play a key part in designing, developing, and integrating software systems—focusing on ground control and onboard software to enable seamless communication, control, and mission execution. You’ll work closely with cross-functional teams to deliver robust, scalable, and compliant software solutions that meet high standards for performance, safety, and regulatory compliance

Responsibilities To Include

• Lead the integration of onboard and ground-based software systems, including Flight Management Systems (FMS), Flight Deck interfaces, and mission control applications.
• Design and implement ground systems for UAV control, including datalink management, Satcom Systems, network routing (TCP/UDP), and real-time telemetry processing.
• Define and integrate the Flight Management System (FMS) capabilities tailored for long-endurance UAV operations, including autonomous navigation, mission planning, and contingency handling.
• Develop and refine intuitive HMI solutions for UAV operators, ensuring situational awareness, mission control, and safety-critical feedback through user-centred design principles. This includes developing interfaces for mission planning, flight control, and telemetry visualisation.
• Establish and maintain software architecture for mission-critical systems, ensuring modularity, scalability, and fault tolerance.
• Gather, evaluate, and manage software requirements to ensure they are traceable and consistently aligned with overarching system goals.
• Conduct and contribute to software-focused design reviews (SRR, PDR, CDR), ensuring alignment with system architecture and mission needs.
• Develop and execute software verification and validation plans, including simulation, hardware-in-the-loop (HIL), and system-level testing.
• Ensure software systems comply with aviation standards such as ARP4754A, ARP4761 and DO-178C and support certification efforts.
• Identify and mitigate software-related risks, including cybersecurity, data integrity, and operational reliability.
• Act as a liaison between software teams and systems engineering, ensuring cohesive integration across avionics, payload, and ground systems.
• Maintain comprehensive documentation of software designs, test results, and integration procedures.
