IRIS2 is the new European Union secure satellite constellation. This project is the European Union's answer to the pressing challenges of tomorrow to provide secure connectivity services and enhanced communication capacities to the EU and its Member States as well as to governmental users, private companies and European citizens while ensuring high‑speed internet broadband to cope with connectivity dead zones.

SES – together with other consortium partners and core members – was selected by European Commission to build and to operate the IRIS2 multi‑orbit satellite constellation. The IRIS2 team enters the next project phase and there is a strong need for support for all the activities around service provisioning and products that the system can offer in the future.

ROLE DESCRIPTION

You will be part of an agile project organization where a flexible way of working and an adaptive mindset is required.

You are responsible for developing concepts, models and specifications for the master schedule of all mission‑related activities for IRIS2’s multi‑orbit satellite constellation (LEO/MEO) in order to prepare the execution at a later stage of the programme. This includes engineering the planning framework (time‑lines, dependencies, resources) – ranging from operator shift scheduling to orbital re‑phasing, payload or ground element configuration changes. The ideal candidate excels in detailed scheduling, cross‑functional and cross‑company collaboration, and specification document preparation, ensuring that each programme and mission milestone is achieved efficiently, on time, and in quality.

PRIMARY

RESPONSIBILITIES Engineering the Planning Framework

Prepare specifications and programme documentation for robust methods and tools (e.g., scheduling software, collaboration platforms) to capture constraints, allocate resources, and track progress.

Integrate best practices in mission planning and scheduling engineering, leveraging feedback from cross‑functional teams and lessons learned from previous missions.

Operation Assurance

Prepare operations of MEO/LEO satellite payload, ground payload control, resource orchestrator, 5G Core Network and all the ground components functional to deliver services, with focus on the monitoring, measurement and reporting of the relevant KPIs.

Engineer efficient and reliable measurement methodologies, based on the next‑generation automation tools, to characterize the health and load status of the service‑support system.

Prepare for the later deployment of the operations.

Resource & Shift Management

Collaborate with operations teams to design shift rotations and on‑call schedules that align with mission demands, safety requirements, and target system availability.

Ensure adequate staffing and skill coverage for mission‑critical activities, optimizing resource planning without compromising mission objectives.

Orbital & Payload Configuration Planning

Coordinate with Flight Dynamics and Payload Engineering teams to schedule orbital maneuvers (e.g., re‑phasing) and payload configuration changes.

Maintain visibility of external factors (e.g., regulatory constraints, ground segment availability) that could impact the scheduling or execution of maneuvers.

Documentation

Produce or contribute to clear, detailed internal and deliverable documents, milestone inputs, and status reports for SES‑internal, Consortium‑level and external stakeholders.

Build and maintain alignment with SES strategy in IRIS2, as well as strong relationships with SES internal departments, IRIS2 Consortium partners, and external stakeholders.

Mission Planning & Scheduling

Experience in developing and maintaining a comprehensive timeline of space and ground mission activities (e.g., shifts, command windows, payload reconfiguration, orbital manoeuvres).

Ability to identify dependencies, resource requirements, and potential conflicts, providing timely resolutions or escalation paths.
