Embedded Software Engineer

Seeking a Contractor – Embedded Software Engineer (willing to consider all levels) for an initial period of 6 months, with the possibility of extension to join our team. In this position you will be expected to work predominantly on-site. You will work collaboratively with our team to develop and innovative satellite solutions. You will be responsible for hardware/software development during all phases of the development cycle, including requirements, design, implementation, test, integration, and documentation in a fast-paced environment.

Responsibilities:

• Develop and maintain embedded software for spacecraft avionics, RF communications, and command & telemetry subsystems.
• Implement and integrate software supporting RF transceivers, modems, and encryption hardware for secure data links.
• Develop command and telemetry processing software including packet routing, protocol handling, and validation.
• Create and test device drivers and APIs for RF and command & telemetry hardware including crypto interfaces and key management.
• Perform end-to-end testing of spacecraft command and telemetry pathways from ground to flight hardware.
• Develop hardware-in-the-loop (HIL) and system-level simulations to validate encrypted communications performance.
• Participate in integration and test campaigns including testbed bring-up, anomaly resolution, and verification.
• Collaborate across RF, software, and systems teams to define interfaces, data formats, and timing requirements.
• Generate and maintain documentation for software requirements, design, test procedures, and verification.
• Contribute to flight readiness, ground system demonstrations, and functional validation of RF and command & telemetry subsystems systems.

Ideal Experience:

• Bachelor’s degree in computer engineering, electrical engineering, computer science, or related field.
• 5+ years of experience developing embedded software for aerospace, defense, or mission-critical systems.
• Proficiency in C and C++ for embedded systems.
• Knowledge of RF and command & telemetry subsystems.
• Familiarity with serial and packet-based interfaces such as RS-422, MIL-STD-1553, CAN, SpaceWire, or Ethernet.
• Strong analytical, troubleshooting, and problem-solving skills for integrated systems.
• Must have the ability to obtain a security clearance.
• Some limited travel required.

Desired Skills

• Master’s degree in computer engineering, computer science, or a related discipline.
• Experience with flight software development or integration for spacecraft communications systems.
• Experience with Python or MATLAB for scripting or analysis.
• Experience with software version control and issue tracking (Git, Bitbucket, JIRA, Confluence).
• Experience developing on real-time operating systems (RTOS) such as VxWorks, RTEMS, or FreeRTOS.
• Knowledge of encryption key management systems and secure key handling protocols.
• Experience with command and telemetry ground systems or mission operations software development.
• Familiarity with RF link analysis, modulation schemes, and bit error rate testing methods.
• Hands-on experience performing software integration and system-level verification in lab environments.
• Experience with encryption devices (e.g., KG-series or Type 1).
• Experience with CCSDS Space Link Extension (SLE) or equivalent ground communication systems.
• Knowledge of autonomy, FDIR, and fault management features related to communications subsystems.
• Experience developing or using digital twin or HIL environments for C&T; system validation.
• Experience leading small software teams or supporting integrated product teams (IPTs
