About the Role

Meridian is building a new model for sovereign space infrastructure, delivering LEO satellite constellations that provide governments and commercial operators with full control, assured access, and sovereign communications capability at a fraction of the cost of independent development. As the RAN & Core Integration Engineer, you will be responsible for developing, building, operating, and automating critical testing infrastructure, specifically the 5G NTN testbed and the 5G NTN Space Lab.

Responsibilities

Lead the design, procurement, and physical build-out of complex, multi-stage 5G NTN testbeds and the 5G NTN Space Lab.
Integrate, operate, and troubleshoot 5G Core (5GC) and Next-Generation Radio Access Network (NG-RAN) elements within lab environments.
Develop automation scripts, tools, and CI/CD pipelines to streamline test execution, automate KPI measurements, and modify testbed configurations.
Analyze and overcome challenges of 5G Non-Terrestrial Networks (NTN), including Doppler shifts, propagation delays, and fading in a LEO environment.
Collaborate with RAN, RF, and systems architects to ensure end-to-end coherence of the Meridian solution.
Contribute to the design and operation of lab environments used to validate architecture and configuration choices.

Requirements

Bachelor's degree in electrical engineering, computer science, telecommunications, or a related field.
Deep understanding of 3GPP NG-RAN and 5G Core (5GC) architectures, interfaces, and protocols.
Demonstrated hands-on experience in designing, procuring hardware for, and building complex telecommunications testbeds or lab environments.
Solid grasp of 5G NTN principles and the specific engineering challenges associated with LEO satellite communication links.
Strong coding and scripting skillset (e.g., Python, Bash, C++) for lab automation, test execution, and continuous integration.
Hands-on lab experience integrating network elements using COTS components and standard interfaces (NG, F1/E1, O1/O2).
Strong interpersonal, verbal, and written communication skills.

About the Company

Meridian is building a fundamentally new model for sovereign space infrastructure—delivering complete, owned Low Earth Orbit (LEO) satellite constellations that provide governments and commercial operators with full control, assured access, and sovereign communications capability at a fraction of the cost of developing these systems independently.
Backed by leading venture capital investors and engineering partners, we are rapidly scaling the design, production, and deployment of the satellites, ground systems, and network infrastructure that will power Meridian's next-generation constellations.
Joining Meridian means working at the forefront of one of the world's most ambitious space programs underway today - designing and building constellations that will put sovereign connectivity within reach of nations and operators worldwide.
You'll be part of a close-knit, collaborative team that thrives in a fast-paced, innovative environment, where your work directly advances the design, development, and deployment of satellite constellations that governments and enterprises around the world will depend on for secure, resilient, and sovereign connectivity.
