Mission Operations Systems Engineer Verified today

About Sateliot

Sateliot is a Barcelona-based satellite company that has built the first satellite constellation allowing standard commercial devices to communicate directly from space. Our goal is to connect everything, everywhere, bringing affordable and secure connectivity across the planet.

About the team and this role

The Mission and Systems Engineering team designs Sateliot's satellites end to end and supports their most critical early-orbit phases: LEOP and commissioning. You will connect spacecraft design, flight software, AIT, ground segment and the flight-control team. During consolidated design, you will turn the Mission ConOps into validated operational products. After launch, you will support LEOP and Commissioning execution until handover to Operations.

What you will do

• Spacecraft operability: consolidate operational concept based on inter-satellite links, operational modes, on-board autonomy and FDIR, ensuring critical states are observable, controllable and recoverable through defined interfaces with ground.
• Build the operational baseline: own the operations handbook, FOP catalogue, flight rules, mission database requirements, constraints, configuration control and handover to routine Operations.
• Prepare procedures and propulsion activities: with subsystem and Flight Dynamics engineers, define spacecraft configuration, command sequences, expected telemetry, readiness criteria, hold and abort criteria, contingency actions and post-manoeuvre assessment.
• Validate operational readiness: coordinate end-to-end tests and operations rehearsal, validating procedures against the MCS and the available test environments, leading to Operational Readiness Review evidence.
• Support LEOP and commissioning: elaborate and execute LEOP and commissioning plans as system-level representative, until handover to routine Operations.

What you bring

• Degree in Aerospace Engineering, Systems Engineering, Telecommunications, Physics or a related discipline.
• 4+ years in spacecraft systems and mission-operations engineering.
• Experience supporting at least one LEOP, commissioning campaign or comparable critical mission phase from a Mission Control Centre or engineering-support position.
• Experience developing and validating FOPs, flight rules, TM/TC databases, MCS displays, alarms, end-to-end tests or operational simulations.
• Understanding of spacecraft subsystem interactions and the ability to diagnose and communicate problems methodically during critical activities.
• Clear technical writing, rigorous configuration control and concise communication of recommendations, assumptions and risks.

Preferred experience

• Experience defining, validating or supporting spacecraft operations with continuous or near-continuous TM/TC via GEO relay or inter-satellite links, including handovers, service loss, reacquisition and routing.
• Experience planning, rehearsing or supporting manoeuvres in LEO; Hall-effect thruster experience is valued.
• Subsystems operational knowledge; familiarity with ECSS PUS services, onboard control procedures, CCSDS packet services and CFDP.
• Experience with Python, spacecraft simulators or hardware-in-the-loop environments; familiarity with warm-redundant avionics and autonomous FDIR is also valued.

Additional requirements

• Professional working proficiency in written and spoken English.
• Based in Barcelona, or able to relocate; this is an on-site role at our Barcelona headquarters.
• Availability for temporary shift work during LEOP, commissioning, end-to-end tests and rehearsals, with occasional travel to ground-segment or test sites. This is not a permanent routine-operations shift role.

What we offer

• Real impact on one of Europe's most ambitious space projects.
• 50% coverage of courses or master's degrees (up to 5% of your salary), plus Spanish and Catalan classes.
• 50% on private health insurance and Urban Sports Club membership, flexible schedule, and hybrid work.
• Flexible compensation through Cobee (meal, transport, kindergarten).
• On-site parking with 50% cost covered by Sateliot, plus free bike parking.
• On-site catering partnership to provide fresh meals.
• Leisure and sports activities both during and outside working hours.
• A dedicated buddy from day one.
