Job description

Spacecraft represent the most pressing unmet need across the entire aerospace industry. As more launch vehicles come online and the cost to orbit decreases, more companies launching payloads to space continue to emerge.

For the first time in history, this influx of payload companies combined with reduced launch costs has resulted in a massive increase in need for commercial spacecraft platforms, known as satellite buses. These buses hold the payloads of our customers and are flown on launch vehicles.

Apex manufactures these satellite buses at scale using a combination of software, vertical integration, and hardware that is designed for manufacturing. Our spacecraft enable the future of society: ranging from earth observation to communications and more.

We’d love for you to join us on our mission of providing humankind access to the galaxy beyond our planet.

Responsibilities

• Design, develop, and implement ground software for satellite communication, control, and telemetry.
• Support commissioning of spacecraft during launch and early operations and ensure ground systems remain functional during critical operations.
• Own ground software solutions through the full lifecycle from initial design to deployment.
• Collaborate with cross-functional teams to baseline product requirements and technical roadmaps.
• Integrate third-party tools and custom software to automate satellite operations, tracking, and data processing.
• Monitor and improve system scalability, redundancy, and failover strategies for ground software and systems.

Requirements

• U.S. Person status is required as this position needs to access export controlled data.
• 6+ years of total ground software experience.
• Bachelor’s degree in CS, EE or equivalent.
• Strong proficiency in programming languages such as Go, TypeScript, Python, and Rust.
• Familiarity with microservices frameworks and tools and cloud-based solutions (e.g., Docker, Kubernetes, gRPC).
• Knowledge of Linux operating systems and system administration.
• Experience with software integration, testing, and validation for real-time and distributed systems.
• Familiarity with network protocols (TCP/IP, UDP), secure communication systems, and encryption.
