Your work spans the entire lifecycle, including pre-sales tools to forecast satellite and network performance, satellite commanding, telemetry monitoring, payload operations, payload testing, and network service coordination. You will tackle soup to nuts engineering problems, taking features from operational concepts through backend services and out to operators in mission control.

This role contributes to both commercial and US Government programs.

Role

• Lead the design, implementation, and lifecycle of software used for satellite commanding, health monitoring, and fleet management.
• Build services and tools that coordinate network operations, payload operations, and automated payload testing.
• Develop analytical and forecasting tools to evaluate satellite and network performance in support of pre-sales and capacity planning.
• Own features end to end, from backend architecture and database modeling to operator-facing interfaces and automation scripts.
• Deliver resilient, high-consequence software workflows that send commands directly to space vehicles and ground stations.
• Build and maintain web-based operator tools for commanding consoles, telemetry visualization, execution tracking, and procedure orchestration.
• Automate operational workflows across spacecraft testing, mission rehearsals, on-orbit operations, and anomaly investigation.
• Partner directly with payload engineers, network engineers, system architects, and flight operators to define operational requirements and software architecture.

Requirements

• Bachelor's degree in Computer Science, a related technical field, or equivalent practical experience.
