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. Joining Meridian means working at the forefront of ambitious space programs, designing and building constellations that will put sovereign connectivity within reach of nations and operators worldwide.
Responsibilities
- Design, develop, and maintain full-stack software solutions for the Meridian Ground Segment, bridging distributed cloud environments with edge networking products.
- Architect scalable software frameworks for the entire ground network, encompassing radio access processing nodes, centralized packet routing and core control planes, constellation-aware network orchestration functions, and unified operations and administration platforms.
- Drive the transition of network applications into scalable, cloud-native microservices utilizing container orchestration, service mesh routing, and modern API design.
- Oversee the software design and integration of virtualized and containerized environments, leveraging high-performance data plane technologies and real-time Linux kernel tuning for near line-rate processing.
- Lead software design reviews and provide technical mentorship to engineering teams to ensure the delivery of resilient, telecom-grade platforms.
- Interface directly with customers, external partners, and domain-expert network architects to shape technical requirements and drive the execution of ground network features.
Requirements
- Bachelor's degree in computer science, software engineering, electrical engineering, or a related field.
- Minimum 10 years of professional software engineering experience, spanning cloud architectures, distributed systems, and edge environments.
- Strong proficiency in a mix of modern programming languages including C/C++, Golang, Python, Java, or Rust.
- Extensive hands-on experience with cloud-native orchestration and containerization frameworks (Kubernetes, Docker, Helm).
- Experience with infrastructure-as-code, configuration management (Ansible, Terraform), and network automation protocols (NetConf, YANG).
- Deep familiarity with modern distributed systems tooling, including RESTful APIs, gRPC, message brokers (Kafka, NATS), and data serialization formats (JSON, YAML).
- Demonstrated expertise in system observability, telemetry, and monitoring stacks (Prometheus, Grafana).
- Knowledge of high-performance packet processing techniques (e.g., DPDK, eBPF) and low-latency systems tuning.
- Proficiency in network protocols and architecture, including TCP/IP, UDP, routing, and network performance optimization.
- Master's degree in computer science, software engineering, telecommunications, or a related field.
- Deep understanding of 3GPP 5G Non-Terrestrial Network (NTN) standards, particularly Release 17/18 architecture encompassing both the Next Generation Radio Access Network (NG-RAN) and 5G Core (5GC).
- Experience with advanced telecom software architectures, including Policy Control Function (PCF/PCRF), IP Multimedia Subsystem (IMS), and VoLTE/TAS solutions.
- Experience working in ESA, defense, or similarly regulated environments.

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.
