Backend Software Engineer - Enterprise Systems

Astranis builds advanced satellites for high orbits, expanding humanity’s reach into the solar system. Today, Astranis satellites provide dedicated, secure networks to highly-sophisticated customers across the globe— large enterprises, sovereign governments, and the US military. With five satellites on orbit and many more set to launch soon, the company is servicing a backlog of more than $1 billion of commercial contracts.
Astranis is the preferred satellite communications partner for buyers with stringent requirements for uptime, data security, network visibility, and customization. Astranis has raised over $750 million from some of the world’s best investors, from Andreessen Horowitz to Blackrock and Fidelity, and employs a team of 450 engineers and entrepreneurs. Astranis designs, builds, and operates its satellites out of its 153,000 sq. ft. headquarters in Northern California, USA.

Before a satellite can be launched into orbit, it needs to be financed, procured, manufactured, and tested.  As a Backend Software Engineer, you will help build the software systems that enable spacecraft development, testing, and manufacturing, while ensuring seamless integration with our supply chain. This high-impact role spans across domains—from procurement and manufacturing to cloud services and data pipelines —and plays a critical part in enabling efficient engineering workflows, business intelligence, and flight operations at scale.

You’ll collaborate closely with cross-functional teams including hardware, manufacturing, operations, and satellite flight control to develop internal tools that  streamline processes and accelerate development.  You will own and deliver scalable systems to ensure that we can build, test, and launch satellites efficiently.

This role supports both commercial and US Government satellite programs.

Role

• Design, implement, and maintain scalable software systems that support hardware design, manufacturing, and automated testing.
• Build out data pipelines that will be used to drive decision making across teams.
• Own backend development for internal tools across test infrastructure, manufacturing, and business intelligence.
• Build integrations with hardware design, procurement, and production platforms such as Altium, Arena, NetSuite, and others.
• Automate manual workflows to increase operational velocity across engineering, production, and satellite operations.
• Collaborate with engineers, operators, and technicians to gather requirements, refine tools, and deliver impactful solutions.
• Own projects from architecture and design through implementation, test, deployment, and iteration.

• Bachelor’s degree in Computer Science, Electrical Engineering, or a related technical field.
• 2+ years of professional software engineering experience.
• Strong proficiency with Python.
• Experience designing and maintaining REST or GraphQL APIs.
• Strong foundation in working with SQL databases (e.g., Postgres).
• Experience deploying backend services to cloud environments (e.g., AWS, GCP).
• Comfortable working in Linux, using shell tools, and managing source control with Git.
• Familiarity with Docker, Kubernetes, or other container-based deployment strategies.

• Experience with platforms like Altium, Arena, NetSuite, First Resonance, Manufacturo, or similar tools used in hardware development.
• Background in manufacturing, logistics, or aerospace systems.
• Familiarity with automated test strategies and embedded system validation.
• Experience developing for real-time telemetry systems or ground control interfaces.
• Experience with hardware-software interfaces, including instrumentation, schematics, and validation workflows.
