Senior Engineer – OSS Platforms, RAN Orchestration

Role Overview

• Deliver projects and services to external and internal customers within the agreed budget, specification and schedule
• Modelling the onboard satellite gNB network using 3GPP Network Resource Models (NRMs), focusing on the CU/DU functional split as per TS 28.541, TS 28.562, and TS 28.622, respectively the transport and slice-level supervision (TS 28.554, TS 28.557)
• Defining the structure and lifecycle of NRM-based inventory and its dynamic management by the Mission Control Center (MCC)
• Specifying periodic configuration flows from the MCC to the gNBs, including Mobile Xn setup and CU reassignment scenarios
• Designing OSS supervision logic covering the onboard gNB lifecycle, from boot-up and configuration to failure handling
• Leading the design of telemetry, event, and fault models compliant with 3GPP OAM standards (TS 32.111, TS 28.550), and defining MCC responses to OISL conditions (e.g. load, link status, failures) based on telemetry KPIs
• Collaborating with simulation engineers to integrate the above models into functional system prototypes
• Analyse and decompose the higher-level requirements into more detailed ones related to the satellite subsystem
• Assess deviations from requirements and evaluate their impact at a higher level to ensure that a critical part of the system and mission objectives are achieved
• Review the technical documentation (e.g., design documentation, test methods, reports) and assess the content's validity
• Define comprehensive test plans and procedures to ensure the system satisfies its requirements, performs as intended; and assist with test operations
• Handle budgets, handle procurements, manage installations and the operational handover of ground segment and communications systems
• In the scope of the project, coordinate with other functions (Project Management, Project Control, Legal, Finance) for the transparent and effective realization of assigned projects
• Interface and engage with external partners (e.g. customers, Consortium partners and suppliers, vendors, etc.);

Requirements

• Master’s Degree in Telecommunications Engineering, Electrical and Electronics Engineering or like field (a combination of experience and education will be considered)
• Minimum 10 years of relevant professional experience in OSS, RAN orchestration, or 3GPP-compliant supervision systems
• Mastery of 3GPP TS 28.x series (especially NRM for CU/DU: TS 28.541, 28.622, 28.554)
• Deep knowledge of RAN architecture (CU/DU/DU pool, Xn management)
• Deep knowledge of Multi-Protocol Label Switching (MPLS) with both IPv4 and IPv6 is a strong asset
• Familiarity with O-RAN SMO concepts and O1/E2, A1 interface supervision
• Understanding of Non-Terrestrial Networks (NTN) is a strong asset
• Comfortable with modeling complex systems using UML
• Experience in requirement-based systems engineering
• Fluency in English, any other EU language is considered an asset.

Tech Stack

• Switching
• TypeScript

Benefits

• Willingness to travel internationally and do regular on-site supplier visits
• ESA/EU SECRET clearances are considered a strong asset
• Candidate must be willing to undergo a security clearance procedure, as this position might require holding security clearance
• Willing to work at least 60% onsite from office
