(Senior) 5G O-RAN Orchestration & SMO Engineer

## PROGRAMME DESCRIPTION meoSphere is SES’s next-generation Medium Earth Orbit (MEO) satellite constellation, designed to deliver secure connectivity services to government agencies, enterprises, and commercial customers. It will also provide high-speed broadband internet to eliminate global connectivity dead zones.

To accelerate development timelines, reduce costs, and ensure quality, SES is internalizing a critical segment of the satellite supply chain: the final integration of partner satellite platforms with SES’s software-defined payloads, all within a cutting-edge manufacturing and test facility. ## ROLE DESCRIPTION SUMMARY As a 5G O‑RAN Orchestration & SMO Engineer, you will be responsible for the Management Plane (M‑Plane) of the regenerative onboard gNBs and for the interface between the onboard 5G stack and the ground/onboard Service Management and Orchestration (SMO) platform.

Your work enables remote lifecycle management - configuration, fault management, and performance monitoring of spaceborne 5G infrastructure, with strong alignment to O‑RAN Alliance and 3GPP TS 28.xxx management specifications.

This is a high‑ownership role for engineers who like shipping real systems: you will define the management interfaces, turn standards into running software, and make it robust enough for mission operations. ## KEY RESPONSIBILITIES - Own the definition and implementation of the O‑RAN Management Plane (M‑Plane) for regenerative onboard gNBs. - Architect the interface between the onboard 5G stack and the SMO platform (ground and/or onboard). - Design and implement the O‑RAN O1 interface to enable remote configuration, fault management, and performance monitoring, aligned with O‑RAN Alliance specifications. - Define O1 interface specifications for the onboard gNB and author custom YANG models representing satellite‑specific parameters. - Architect and prototype a secure NETCONF/TLS agent for handling ground‑initiated Get/Set management operations. - Define and implement logic for fault reporting (alarms) and performance data collection (PM counters).

COMPETENCIES, QUALIFICATIONS & EXPERIENCE - Builder’s mindset with a track record of shipping real systems , not prototypes - ideally telecom infrastructure, or other high‑reliability environments. - Degree in Aerospace Engineering, Electrical Engineering, Mechanical Engineering, Telecommunications, Physics, or a related field. - Good experience owning end‑to‑end technical scope , from architecture and standards interpretation through implementation and operational readiness. - Deep, practical understanding of O‑RAN management , including the O1 interface and the 3GPP TS 28.xxx management framework, applied in production systems. - Hands‑on experience designing and operating SMO‑driven lifecycle management , covering configuration, fault, and performance domains. - Proven ability to design clean, extensible management models using YANG and to implement them over NETCONF/REST‑based interfaces. - Strong software engineering background with production experience in C/C++ and Python , including ownership of code quality, robustness, and maintainability. - Experience building and securing management interfaces using TLS‑based communications in constrained or high‑latency environments. - Systems thinker comfortable working across boundaries (payload, platform software, ground systems) and making trade‑offs under real operational constraints. - Thrives in high‑ownership, fast‑execution environments where accountability, technical judgment, and bias toward action matter more than process. ## Nice to Have - Prior experience working on spaceborne, airborne, or other highly constrained platforms , where latency, bandwidth, and reliability are first‑order design drivers. - Hands‑on involvement with O‑RAN Alliance activities, working groups, or interoperability efforts. - Experience integrating management systems with ground segment or mission operations environments.

OTHER KEY REQUIREMENTS - Eligibility for ESA/EU/NATO/National SECRET personnel security clearances.

Candidates must be prepared to undergo a security clearance procedure, as this position may require holding such clearance, is considered an asset. - Willing to work at least 60% onsite from office - Able to travel nationally & internationally The salary range for this full-time position (US only) is $110,400 - $151,800 . Salary ranges are determined by role, level, and geographic location.

Individual compensation within the range is determined based on work location and a variety of factors, including job-related skills, experience, qualifications, and relevant education or training. Additional compensation and benefits may apply depending on the location and terms of employment. SES and its Affiliated Companies are committed to providing fair and equal employment opportunities to all.
