SpaceRelays

Location: Remote / Part-time Advisory Compensation: ESOPs (4-year vesting) About SpaceRelays SpaceRelays is building an optical relay satellite network to enable real-time, high-speed data transfer for LEO satellites. We are pioneering the optical communication technology, creating the backbone for next-generation space connectivity. Role Overview We are seeking an experienced Startup Advisor in Space Mission Design & Planning with deep expertise in satellite systems, orbital mechanics, and communication technologies. The advisor will guide our mission design strategy, ensure robust mission planning, and provide technical oversight from concept to prototype. Key Responsibilities Define and refine mission architecture for an optical relay satellite network. Develop mission planning frameworks, including trajectory design, orbital parameters, and system requirements. Advise on spacecraft bus design, payload integration, and subsystems optimisation. Provide insights on inter-satellite optical links, pointing, acquisition, and tracking (PAT) systems. Support feasibility studies, risk analysis, and technology readiness assessments. Required Skills & Expertise 15+ years in satellite mission design, planning, or systems engineering. Strong background in orbital mechanics, trajectory optimisation, and attitude control. Knowledge of optical communication systems (highly desirable). Experience with mission-level risk assessment, scheduling, and cost analysis is a plus. Relevant Software Proficiency STK (Systems Tool Kit) – mission design & orbital simulations. GMAT / Orekit – astrodynamics and trajectory optimisation. MATLAB / Simulink – modelling and control system simulations. Python / C++ – for simulation scripting and automation. Compensation Equity-based compensation via ESOPs, vested over 4 years.
