Senior Network Engineer

We are building a next-generation network connecting satellites, ground stations, and cloud infrastructure. This system must operate across dynamic, intermittent links and deliver data reliably into cloud-based workloads. We are looking for a Network Engineer to strengthen the systems deployed directly at our antennas, a set of servers and network devices installed on-site to receive, demodulate, and transport satellite data to the cloud.

This is a hands-on role working across routing, overlay networking, edge systems, and cloud connectivity.

Your responsibilities will include:

• Network Design & Architecture: Design L3 network topology across satellite, ground, and cloud environments, define IP addressing schemes, segmentation, and routing domains and model connectivity patterns and failure scenarios.
• Routing & Connectivity: implement and operate dynamic routing, design route advertisement, filtering, failover strategies and handle intermittent and flapping connectivity.
• Overlay & Secure Networking: build secure multi-hop paths, ensure encryption, isolation, and performance. Implement secure tunnel configurations (WireGuard / IPsec). Define and enforce SSH access policies, firewall rules and least-privilege communication.
• Automation & Infrastructure: develop automation using Terraform/Ansible. Support scalable rollout and configuration management.
• Operational Integration: Align networking behavior with satellite scheduling and design safe state transitions and failover scenario. Improve observability.

Qualifications:

We’re looking for Senior Network Engineer with solid technical fundamentals and the drive to learn quickly working across architecture, implementation and troubleshooting with strong ownership and problem-solving mindset.

Required Skills:

• Strong experience with IP networking and routing (advanced level)
• Hands-on experience with BGP (design, operation, troubleshooting) and distance vector protocols.
• Solid understanding of IP networking (routing, switching, TCP/IP, VLANs, MTU, complex NAT) and of Linux networking.
• Experience designing and operating VPNs and tunnelling technologies in complex, distributed environments (WireGuard, StrongSwan, GRE + IPsec)
• Experience with AWS networking (VPC, TGW, Cloud WAN, VPN) and edge or hybrid networking environments.
• Understanding of overlay vs underlay networking.
• Very strong experience with automation (Terraform, Ansible, or similar).
• Strong interest in distributed systems, connectivity, or infrastructure engineering.
• Ability to script or code in Python, Bash, or Go.
• Ability to debug complex distributed systems.

Nice to have

• Exposure to satellite, telecom, or RF systems (non-essential)
• Experience with hardware operations, rack installation, or cable management.
• Familiarity with AWS or any cloud environment.

Spire operates a hybrid work model, and this position will require you to work a minimum of three days per week in the office.

Access to US export-controlled software and/or technology may be required for this role. If needed, Spire will arrange the necessary licenses—this is not something candidates need to have before applying. _#LI-RK1
