Sateliot is a Barcelona-based satellite company with one goal: connect everything, everywhere. Founded in 2018, we've built the first satellite constellation that lets standard commercial devices communicate directly from space. Our technology bridges the gaps that terrestrial networks will never reach, bringing affordable and secure connectivity to industries, governments, and communities across the planet.

The Mission and Systems Engineering team designs Sateliot's satellites end to end and supports their most critical early-orbit phases: LEOP and commissioning. This role connects 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, including requirements, databases, procedures, flight rules, end-to-end tests, simulations, rehearsals and readiness evidence. After launch, you will support LEOP and Commissioning execution until handover to the Operations team.

What you'll 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 comm
