Software Engineer (Mission Applications)

Astranis builds advanced satellites for high orbits, expanding humanity's reach into the solar system.

As a Software Engineer on the Mission Applications team, you will design, build, and administrate the mission-critical software used to command, monitor, and coordinate our satellites and ground networks.

Responsibilities:

• 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.
