• 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.

• 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

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