Job Level
Tech Stack
About the role
- 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).
Requirements
- 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.
Benefits
- Eligibility for ESA/EU/NATO/National SECRET personnel security clearances.
- Willing to work at least 60% onsite from office
- Able to travel nationally & internationally
