Working in our Chief Technology Office (CTO) The CTO division is where Open Cosmos technology comes to life. Covering engineering, product development, and technical innovation, the team designs, builds, and operates the satellites, systems, and platforms that make our missions possible. It’s a highly collaborative environment where ideas become real hardware, software, and data solutions that deliver impact from space. Our Systems Team brings together brilliant Systems, AOCS and Thermal Engineers who turn ambitious mission concepts into reality. They design, integrate, and optimise every detail – from spacecraft architecture to next-generation optical payloads – making sure every system fits, works, and thrives in orbit. From first sketch to launch day, they own the journey, ensuring our satellites deliver maximum impact back on Earth. Lead the delivery of robust, high-quality AOCS solutions across multiple satellite missions—ensuring technical performance, reliability, and on-time delivery. 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. 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. Proactive, self‑driven and motivated by ownership of performance and outcomes. Practical, hands‑on, and solutions‑focused with strong engineering intuition.
