As a Ground Software Engineer at Firefly Aerospace, you will design and build the mission-critical systems that operate our spacecraft and from the ground. This role requires full-stack expertise to deliver robust web applications, backend services, databases, and cloud infrastructure that power spacecraft commanding, telemetry, and real-time control.

You will develop ground systems that interface directly with our vehicles, supporting everything from pre-launch checkout to on-orbit operations. With strong skills in modern software technologies and a deep understanding of real-time control systems, you will create reliable, secure, and scalable software that ensures Firefly missions succeed from liftoff to lunar landing.

RESPONSIBILITIES

• Design, implement, and maintain spacecraft ground software systems, spanning front-end, back-end, databases, and cloud services.
• Develop real-time control interfaces for commanding and telemetry visualization.
• Build and maintain React-based web applications for operator consoles and mission control tools.
• Develop backend services in Python and integrate with spacecraft APIs and communication protocols.
• Design, optimize, and maintain database solutions for mission telemetry and historical data.
• Deploy and manage containerized applications using Docker and Kubernetes.
• Implement cloud infrastructure and scaling solutions in AWS for mission operations.
• Integrate CI/CD pipelines and DevOps best practices to accelerate development and deployment.
• Collaborate with flight software, GNC, and systems engineering teams to ensure seamless end-to-end vehicle integration.
• Contribute to operations software for rehearsals, test campaigns, and live mission execution.
