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.
We are seeking a highly capable Senior Full-Stack Software Engineer to build the software systems that enable automated testing, manufacturing, and real-time control of our flight hardware and spacecraft. You will work across disciplines—hardware, embedded, operations, production, and software—to design full-stack applications that automate and validate critical flight components and support test, integration, and ground control.
This is a high-impact, multidisciplinary role. You’ll own the development of internal tools used to test, operate, and monitor spacecraft—ranging from low-level hardware interfaces to web-based control panels for telemetry and command operations.
Role- Design and implement software systems that support automated testing of hardware components and spacecraft systems.
- Own UI and backend development for internal tools used in test infrastructure, manufacturing and spacecraft operations.
- Develop component- and system-level automated production infrastructure using Python and full-stack tools.
- Work closely with satellite operators and manufacturing technicians to build UI workflows that streamline mission operations, command execution, and telemetry visualization.
- Drive cross-functional collaboration on software architecture, technical design, and hardware/software test strategy.
- Contribute to recruiting and interviewing efforts as we scale the team.
- 5+ years of professional experience as a full-stack software engineer (excluding internships).
- Strong Proficiency with React JavaScript/TypeScript and Python
- Experience with FastAPI or similar frameworks
- Experience working with relational/SQL databases (e.g. Postgres)
- Experience building and maintaining REST APIs and backend services.
- Comfortable working in Linux, using shell tools, and managing source control with Git.
- Experience with SQL/relational databases (e.g., Postgres).
- Comfortable rapidly prototyping and fully developing user interface concepts with focus on overall user experience
- Comfortable diving into all layers to implement both front-end and back-end components of new features
- Experience deploying backend services to cloud environments (e.g., AWS, GCP) and on-prem
- Experience developing tools for hardware or embedded systems.
- Experience with Docker, Kubernetes, or containerized deployments.
- Familiarity with design systems and rapid UI prototyping for internal tooling.
- Background in satellite operations, aerospace, or real-time telemetry systems.
- Experience with test instrumentation, schematics, and debugging interfaces between software and hardware.
- Strong understanding of automated test strategies and validation workflows for embedded or hardware-integrated systems.
- Experience building and deploying sw for a manufacturing environment.
- Experience reading datasheets, debugging analog/digital interfaces, and working with tools like oscilloscopes or logic analyzers.
Base pay is just one component of Astranis’s total rewards package. Your compensation also includes a significant equity package via incentive stock options, high-quality company-subsidized healthcare, disability and life insurance, 401(k) retirement planning, flexible PTO, and free on-site catered meals.
