Senior Communications Network Engineer

Overview

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
.

• 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 (Wire Guard/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 scenarios. Improve observability.

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 (Wire Guard, Strong Swan, 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).
• Ability to script or code in Python, Bash, or Go.
• Ability to debug complex distributed systems.

• 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.
