What You'll Be Doing

As a senior member of our Systems Engineering team, you will:

• Lead the delivery of robust, high-quality AOCS solutions across multiple satellite missions - ensuring technical performance, reliability, and on-time delivery.
• Own the AOCS subsystem architecture: defining requirements, contributing to FMECA, shaping FDIR strategies, and supporting CONOPS development.
• Model, simulate, and analyse AOCS concepts, algorithms, sensor suites and actuator configurations, performing trade-offs and optimisation studies.
• Develop and maintain AOCS simulation environments, analysis tools, and test equipment.
• Plan and conduct lab tests, including hardware-in-the-loop and software validation activities.
• Interpret test results, identify issues, and drive corrective actions to improve performance.
• Maintain and evolve the AOCS roadmap - identifying capability gaps and introducing new technologies aligned with EO, telecom and demonstration mission needs.
• Support bids and pre-sales work with feasibility assessments and technical contributions.
• Provide expert guidance to mission teams, operations, and customers on AOCS behaviour and operational considerations.
• Collaborate closely with suppliers and partners to evaluate sensors, actuators, algorithms, and emerging solutions.

What You’ll Bring

You’re a hands-on engineer with strong analytical capability, practical intuition, and a passion for building real spacecraft. You’ll bring:

• Proven ability designing, analysing and testing AOCS subsystems (sensors, actuators, algorithms or control software).
• Hands-on familiarity with high-end AOCS solutions for EO or telecommunications missions.
• Strong proficiency with MATLAB/Simulink and simulation model development.
• Understanding of hardware/software interfaces, electronics, or embedded systems relevant to AOCS.
• Experience in laboratory validation, test automation or iterative prototyping.
• Working knowledge of FMECA, FDIR, and CONOPS development.
