Kepler is seeking a Network Architect to join our Network Engineering team. In this role, you will design, build, and operate our mission‑critical networks that support our constellation of satellites and, ultimately, customers of the Kepler Network; ensuring performance, scalability, and reliability. Your secondary responsibility will be to design, build, and operate Kepler’s internal corporate networks (on‑premises and cloud). The ideal candidate will have extensive hands‑on experience with complex networks and will fully embrace software and automation initiatives.

This includes driving network automation and programmability while working closely with network architects, software engineers, and FPGA developers to deliver services to our customers.

• Work with network architects to design, build and operate Kepler’s mission‑critical networks.
• Contribute to the team to design, build and operate the corporate network infrastructure, including LAN, WAN, Wi‑Fi, security appliances, and hybrid cloud connectivity.
• Manage network security and segmentation, ensuring infrastructure adheres to security best practices and company policies.
• Design and maintain hybrid cloud networking architectures, integrating on‑prem environments with AWS services.
• Develop and maintain network automation tools, leveraging Python, Ansible, and infrastructure‑as‑code approaches to improve reliability and operational efficiency.
• Collaborate closely with software, FPGA, and mission operations teams to support network infrastructure for satellite operations and ground systems.
• Provide operational support for corporate and service provider network infrastructure, including participation in on‑call rotations.
• Implement monitoring, logging, and observability tools to proactively detect and resolve network issues.
• Maintain accurate network documentation, diagrams, and operational runbooks.
• Participate in change management processes, including planning, implementation, and post‑change validation.
• Support incident response and root cause analysis for network‑related outages or performance issues.

• Strong foundation in routing and switching concepts (ISIS, MPLS, BGP, GRE, VLAN) at an equivalent level to CCNP.
• Hands‑on experience deploying and supporting large WAN environments.
• Hands‑on experience designing and operating hybrid cloud networking, including AWS VPCs, TGW routing, VPN connectivity, and secure integration with on‑prem networks.
• Hands‑on experience with software defined network concepts, including:
  • Network Function Virtualization
  • Infrastructure as Code
  • CI/CD
  • Python scripting
  • Jinja templating
  • Terraform
  • JSON/YAML configuration formats
  • Ansible playbooks and automation workflows
  • Git version control
• Basic Linux networking knowledge including interface configuration, routing tables, firewall rules, and troubleshooting connectivity.
• Hands‑on experience implementing and managing IPsec VPNs for site‑to‑site and remote connectivity.
• Hands‑on experience implementing network monitoring and observability platforms, such as SNMP‑based monitoring, Net Flow/sFlow, or telemetry pipelines.
• Hands‑on experience managing network infrastructure changes, including structured change management practices.
• Strong systems‑level thinking, with the ability to design integrated network solutions supporting complex distributed systems.
• Strong problem solving and troubleshooting skills across multiple layers of the network stack.
• Strong documentation…
