Senior Full-Stack Software Engineer - Enterprise Systems

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.

Requirements

• 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.
• Comfortable rapidly prototyping and fully developing user interface concepts with a 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.

Bonus

• 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 software for a manufacturing environment.
• Experience reading datasheets, debugging analog/digital interfaces, and working with tools like oscilloscopes or logic analyzers.

Benefits

All our positions offer a compensation package that includes equity and robust benefits. 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.

Base Salary: $145,000 – $210,000 USD.

U.S. Citizenship, Lawful Permanent Residency, or Refugee/Asylee Status Required

(To comply with U.S. Government space technology export regulations, applicant must be a U.S. citizen, lawful permanent resident of the United States, or other protected individual as defined by 8 U.S.C. 1324b(a)(3)).

Our mission and our products are meant to connect the world and everyone in it, regardless of gender, race, creed, or any other distinction. We believe in a diverse and inclusive workplace, and we encourage all people to join our team and bring their unique perspective to help make us stronger.
