About the role

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.

Responsibilities

• 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 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

• High-quality company-subsidized healthcare, disability and life insurance.
• 401(k) retirement planning.
• Flexible PTO.
• Free on-site catered meals.
