Apex manufactures satellite buses at scale using a combination of software, vertical integration, and hardware that is designed for manufacturing. These buses hold the payloads of our customers and are flown on launch vehicles. The 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.

  • 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.

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.
  • 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.
