Embedded Systems Engineer

About The Team

Space Systems - The Components

• Develop, implement, and iterate mission-ready core technology.
• Design, build, and test an array of critical components and subsystems, including power systems, communications, control systems, deployment hardware, avionics, and payloads.
• Create flight-proven reliability through rigorous testing and validation.

About The Job

Umbra is seeking an Embedded Systems Engineer with a strong firmware background to support development of mission-critical satellite systems.

Key Responsibilities

• Design, implement, and debug low-level drivers (SPI, UART/RS-485, GPIO, timers, interrupts).
• Participate in code reviews and MR support, ensuring code quality and maintainability.
• Contribute to architecture/design documentation (e.g., RFCs, ADRs, timing diagrams, interface definitions).
• Develop embedded firmware in C and Rust for bare-metal and RTOS-based microcontroller systems.
• Bring up and debug hardware systems, including board-level validation and peripheral integration.
• Support system integration and verification across avionics, radios, and other spacecraft subsystems.
• Define and execute test plans for firmware and hardware validation.
• Troubleshoot issues across firmware, hardware, and system interfaces.
• Contribute to shared firmware infrastructure, including HALs, drivers, and reusable libraries.
• Improve development workflows through contributions to repository structure, CI/CD, and test infrastructure.
• Collaborate cross-functionally with electrical, systems, and flight software engineers.
• Document designs, test procedures, and debugging processes to ensure repeatability and reliability.
• Support test campaigns and mission-critical milestones as needed.

Requirements

• Bachelor's degree in Electrical Engineering, Computer Engineering, or a related technical field.
• 5+ years of professional experience in embedded systems or firmware development.
• Experience developing and debugging embedded communication and control interfaces, including SPI, UART/SCI (e.g., RS-485), and GPIO/interrupts.
• Strong proficiency in embedded C and/or Rust programming.
• Hands-on experience with hardware bring-up and debugging on physical systems.
• Ability to read and interpret electrical schematics and data sheets.
• Experience with debugging tools such as oscilloscopes, logic analyzers, and debuggers (e.g., JTAG/SWD).
• Experience with system integration and verification.
• Experience with version control systems (e.g., Git) and collaborative development workflows.
• Strong problem-solving skills and ability to execute independently.
• Effective communication and ability to work in a cross-functional team environment.

Desired Qualifications

• Experience with RTOS-based embedded systems.
• Familiarity with hardware/software integration at the system level.
• Experience contributing to CI/CD pipelines or automated test infrastructure for embedded systems.
• Experience developing or maintaining HALs, drivers, or shared firmware libraries.
• Background in aerospace, defense, or other high-reliability environments.
• Comfort working in a fast-paced, hardware-centric development environment.
• Demonstrated ownership of projects from concept through validation.
• Experience working in Agile/PI planning environments.
• Experience supporting system-level testing or qualification efforts.
