Senior 5G Systems Engineer

SpinLaunch is pioneering a new era of scalable space infrastructure. Following years of innovation in alternative launch systems, we're now applying that same disruptive mindset to orbit—developing Meridian Space, a ground-breaking broadband satellite constellation built for rapid deployment and low-cost global coverage. With backing from industry leaders, SpinLaunch is positioned to deliver a fully integrated ecosystem of launch, satellite, and connectivity services. Join us in our mission and be an integral part of a close-knit, collaborative team that strives in a fast-paced, innovative environment. This will be an on-site position located at our Long Beach, CA headquarters or a remote position located in Europe or the United Kingdom. Your Mission on the Team As Senior 5G Systems Engineer – Ground & Access Network, you will play a key role in advancing our next-generation 5G Radio Access Network (RAN) architecture for the Meridian LEO constellation. This includes adapting terrestrial 5G technologies for non-terrestrial network (NTN) environments, developing NTN-compliant gNB systems, and ensuring reliable end-to-end performance across space and ground segments. We are building a cloud-native RAN, leveraging modern orchestration and containerization frameworks to achieve scalability, automation, and operational efficiency. The role requires deep expertise in 5G RAN and cloud computing — combined with the ability to apply that knowledge to unique NTN challenges. Your work will be at the intersection of space and telecom, enabling high-throughput, low-latency, standards-compliant services for enterprise, government, and wholesale markets worldwide. Key Responsibilities Lead the design and integration of a 5G satellite RAN. Develop and validate NTN-compliant RAN components, ensuring standards alignment and robust performance under orbital dynamics. Contribute expertise in cloud-native architectures for telecom, including containerized microservices and orchestration frameworks. Collaborate across RAN, core, and satellite engineering teams to deliver reliable end-to-end system performance. Support testing and validation through simulation platforms, lab environments, and field demonstrations. Engage in regulatory, interoperability, and vendor evaluation processes to ensure compliance and ecosystem compatibility. Drive scalability, security, and resilience in the ground access network design Basic Qualifications Bachelor's or Master's degree in Electrical Engineering, Computer Science, Telecommunications, or related field. 5+ years (senior level) or 3+ years (mid-level) of experience in 5G RAN design, testing, or deployment. Strong understanding of 5G NR protocols and 3GPP standards (mobility management, QoS, slicing). Hands-on experience with network protocols, network services, RF link budgeting, and PHY/MAC layer optimization. Familiarity with cloud-native software development: Kubernetes, containers, and software design rules for making microservices independent and horizontally scalable. Proficiency in telecom networking (TCP/IP, routing, switching, security). Scripting and automation skills (Python, Bash, or similar). Strong communication skills and ability to work in cross-disciplinary teams. Preferred Qualifications Advanced degree (Master's or PhD) with a focus on wireless technologies, telecommunications networks, or software development. 8+ years in large-scale wireless communications networks, ideally including NTN or satellites. Deep expertise in RAN functions and experience with DU, CU, and RRU implementations. Familiarity with open-source or commercial 5G Core software. Experience with automated orchestration of telecommunications networks. Background in cybersecurity for telecom or mission-critical infrastructure. Knowledge of satellite ground systems (antennas, modems, RF equipment) and their interface protocols. Experience with high-availability computing, network diagnostics, and performance optimization. Understanding of satellite constellation operations, link budgets, and orbital dynamics.
