Senior Backend Software Engineer

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.

Senior Backend Software Engineer, Software Integrations

Before a satellite can be launched into orbit, it needs to be financed, procured, manufactured, and tested.  As a Software Integrations Engineer, you will play a critical role in building out the infrastructure and business insights that will enable us to build satellites faster and more efficiently. You will own and implement internal software that powers hardware design, manufacturing, and business intelligence across our satellite development programs.

You’ll work cross-functionally to identify inefficiencies, streamline workflows, and build tools to support our growing fleet of spacecraft. This is an opportunity to own and implement data-driven tools that will enable Astranis to scale our operations across multiple functions.

This role supports both commercial and US Government satellite programs.

Role

• Design, implement, and maintain software systems and applications that support hardware engineering, manufacturing, and operational workflows.
• Build data warehouse infrastructure and pipelines that will be used to drive decision making across teams.
• Design and implement AI agent workflows to automate internal processes.
• Integrate with key hardware design, manufacturing and procurement systems such as Altium, Arena, and NetSuite to enable seamless data flow and process alignment.
• Identify and implement automation opportunities to eliminate manual steps and increase velocity across engineering and business operations.
• Build intuitive, performant user interfaces that provide insights into workflow progress, efficiency metrics, and historical trends.
• Collaborate with stakeholders to gather requirements, refine workflows, and propose scalable software solutions.
• Own features through the full development lifecycle — from concept and architecture through implementation, test, and deployment.

Requirements

• Bachelor’s degree in Computer Science, Electrical Engineering, or equivalent technical background.
• 5+ years of software development experience, preferably in environments supporting physical product development.
• Proficiency with Python or similar high-level object-oriented programming languages.
• Experience with relational databases (e.g., Postgres) and REST/GraphQL API integrations.
• Experience deploying backend services to cloud environments (AWS, GCP, etc.).
• Background in building data pipelines and working with performant warehouses/data lakes (Redshift, Snowflake, Databricks).

Bonus

• Familiarity with manufacturing, logistics, and hardware design tools (Altium, Arena, Netsuite, First Resonance, Manufacturo, …)
• Familiarity with Docker and Kubernetes
