Principal Ground Software Engineer

At Reflect, you will be expected to move fast, have a lot of ownership and, most importantly, be able to effect change. If this excites you, we are interested in hearing about your best work and accomplishments across any domain and from any points in your life. About the Role As a Principal Satellite Ground Software Engineer, you'll set the technical direction for the ground segment: the architecture that takes us from operating single satellites with hands-on passes to operating a constellation with minimal operator involvement. You'll make the build/buy/extend calls on core infrastructure and be responsible for ground segment readiness at every launch. This is a hands-on role on a small team. You'll write code, deploy and operate what you build, and troubleshoot issues that span software, networks, and hardware. You'll also mentor engineers, review designs across the team, and make the architectural decisions the rest of the ground segment builds on. Responsibilities - Define the ground segment architecture and technical roadmap: command and telemetry systems, ground station network strategy, data infrastructure, and automation - Make build/buy/extend decisions on command and control infrastructure, mission planning, fleet management, and ground network and GSaaS providers - Design for constellation scale: automated contact scheduling across many satellites and sites, fleet-wide telemetry and alerting, and increasing automation of routine operations - Define engineering practices across the ground/flight boundary, including interface documentation and simulation and hardware-in-the-loop test infrastructure - Lead ground segment work through launch campaigns, commissioning, and major anomalies - Build security into the ground segment from the start: link protection, key management, and access control - Improve the reliability and observability of mission-critical ground systems - Mentor engineers, review designs and code, and support hiring for the ground software team Qualifications - Bachelor's degree in Aerospace Engineering, Computer Science or a related technical field, or equivalent experience - 10+ years of experience developing ground systems software (services, APIs, and applications) - Experience setting technical direction for a ground segment or comparable real-time infrastructure - Experience taking satellites, or a comparable hardware fleet, through launch, commissioning, and sustained operations - Experience deploying and operating software on AWS, including container orchestration with Kubernetes and CI/CD systems - Strong understanding of networking protocols, routing, VPNs, and secure connectivity - Knowledge of satellite ground systems, including ground station networking, antenna interfaces, and RF subsystems - Experience building services around databases and real-time data (relational or time-series) - Strong programming and scripting skills (Python, C++, and/or Rust) - Familiarity with Linux environments and command-line tools - Experience building software for multi-satellite constellation operations is a plus Even if you don’t meet 100% of the above qualifications, we are likely still interested in hearing from you. Hiring exceptional individuals is our #1 priority, and we believe that exceptional people often have highly unusual backgrounds. We are also interested in carving out unique roles for unconventional people that we are excited about working with.
