As a senior member of the team, you will provide technical leadership, contribute to architectural decisions, coordinate with cross-functional engineering teams, and ensure technical deliverables meet program requirements and schedules.

Key Responsibilities

  • Design, develop, test, integrate, and maintain embedded flight software from concept through subsystem integration and full-system deployment.
  • Develop and support core flight software used within spacecraft and embedded systems.
  • Maintain and modify HDL-based designs to provide functionality aligned with system and mission requirements.
  • Integrate microcontroller-based software into systems supporting spacecraft command, control, telemetry, and related functionality.
  • Develop and maintain software for real-time and resource-constrained embedded environments.
  • Participate in software and system architecture decisions, including evaluation of design alternatives and technical tradeoffs.
  • Serve as a senior technical contributor, helping translate program and system requirements into executable engineering tasks.
  • Collaborate with electrical, FPGA, systems, test, operations, and other engineering disciplines to architect and implement new capabilities.
  • Support hardware/software integration, system verification, troubleshooting, and test activities.
  • Perform debugging and root-cause analysis across software and hardware interfaces.
  • Participate in code reviews, design reviews, testing, and technical documentation activities.
  • Help coordinate technical milestones, schedules, deliverables, and engineering dependencies.
  • Support existing systems and development of future spacecraft platforms.

  • Experience developing software for embedded and resource-constrained systems.
  • Experience working with FPGAs and/or SoCs.
  • Proficiency with HDL such as Verilog or VHDL.
  • Experience with logic simulation, HDL design verification, and hardware/software integration.
  • Experience working in multi-threaded software environments.
  • Strong understanding of concurrency, synchronization, and inter-process communication.
  • Experience developing software for a Real-Time Operating System (RTOS) environment.
  • Familiarity with FreeRTOS or comparable real-time operating systems.
  • Experience with embedded communication protocols such as RS-232, RS-485, CAN, and SPI.
  • Experience using embedded debugging interfaces such as SWD and JTAG.
  • Hands-on experience with oscilloscopes, logic analyzers, and multimeters.
  • Ability to read, interpret, and troubleshoot circuit diagrams and electrical schematics.
  • Comfortable working in Linux environments and using command-line development tools.
  • Experience with contemporary software development workflows, including source control, code reviews, unit testing, issue tracking, and continuous integration.
  • Strong technical troubleshooting and problem-solving abilities.
