SES is building and operating IRIS2, a secure European Union multi-orbit satellite constellation, with consortium partners and core members.

What you will do

• Analyse stakeholder, service, system, and subsystem inputs and transform them into clear, complete, consistent, and testable system requirements.
• Define and maintain functional and non-functional requirements covering performance, availability, operability, maintainability, security, interfaces, monitoring, and verification.
• Manage requirements baselines, traceability, change impact analysis, compliance matrices, gap lists, and requirements maturity reporting using JAMA, JIRA, or equivalent tools.
• Support MBSE activities including functional decomposition, use-case modelling, operational scenarios, architecture-to-requirement mapping, and verification planning.
• Coordinate with system, software, RAN, core network, ground segment, operations, and IVV teams to allocate requirements and define verifiable acceptance criteria.

Requirements

• Master’s degree in engineering or science, preferably in Systems Engineering, Telecommunications Engineering, Software Engineering, Aerospace Engineering, or a related field.
• 10+ years of relevant industry experience required.
• Strong knowledge of systems engineering practices, requirements analysis, functional and non-functional requirements specification, verification and validation, and MBSE methods.
• Hands-on experience analysing, writing, reviewing, and maintaining system requirements in a structured engineering lifecycle.
• Experience defining requirement attributes, acceptance criteria, verification methods, traceability links, coverage status, and compliance evidence.
• Practical knowledge of system decomposition, interface definition, operational scenarios, use cases, and architecture-to-requirement consistency checks.
• Experience with requirements and project management tools such as JAMA, JIRA, DOORS, Confluence, or equivalent environments.
• Experience in telecom, satellite communications, aerospace, defence, or other complex system programmes.
• Fluent English and the ability to communicate complex requirements, gaps, risks, and verification status to technical and non-technical stakeholders.
• Ability to work with cross-domain technical teams and suppliers, manage technology development and reviews, coordinate technical studies and supplier interactions, and meet tight development, procurement, and delivery schedules.
• Must be eligible for a “SECRET” security clearance under applicable national regulations and EU/ESA/NATO equivalents.

Nice to have

• Experience with 5G, 5G-NTN, satellite communications, RAN, core network, ground segment, or complex telecom system engineering programmes.
• Experience preparing requirement baselines for RFI, RFP, RFQ, supplier evaluation, compliance analysis, or contract-level technical documentation.
• Experience configuring or using JAMA/JIRA workflows, dashboards, filters, reports, and review processes for engineering governance.
• Knowledge of V-model development, IVV planning, test case derivation, verification closure, and requirements-based acceptance management.
• Experience managing R&D projects and coordinating requirement reviews, technical studies, and supplier interactions.
• Additional languages.
