Avionics System Engineer III - Command & Data Handling

Job Summary

As a Senior Avionics Systems Engineer within the Lunar Permanence team, you will play a pivotal role in developing the Blue Moon landers and associated infrastructure, essential for transporting crew and cargo to the lunar surface.

• Contribute to or lead C&DH architecture trade studies, concept development, verification planning, vehicle integration, and operations support.
• Analyze, manage, and interpret requirements at the C&DH subsystem level and flow down requirements to lower-level component specifications.
• Generate verification and validation plans, and work with the Integration and Test team to ensure the C&DH subsystem meets requirements.
• Develop and manage network architecture, integrating multiple subsystems while ensuring deterministic performance and budget compliance.
• Develop and manage C&DH fault tree analyses and other reliability analyses across the system lifecycle.
• Produce technical writing (procedural definitions, specifications, interfaces, analysis support and description documents).
• Contribute to design reviews (SRR, PDR, CDR) and ensure technical artifacts meet quality and compliance standards.
• Provide technical mentorship and peer review within the avionics engineering team.

• B.S. in Aerospace, Mechanical, Electrical, Chemical Engineering, Computer Science, or related technical subject area.
• 5+ years relevant experience in the full life cycle development of avionics systems, including requirements, design, integration, test, and operations.
• Highly knowledgeable of systems engineering practices, integration processes, and mission/safety critical systems.
• Understanding of requirements definition, decomposition, and flow-down, circuit design, interface definition, hardware specifications, interface control, analyses, and verification.
• Demonstrated expertise delivering complex, safety critical C&DH or similarly highly integrated avionics systems involving multiple subsystems and networked and IO interfaces.
• Demonstrated expertise related to configuring and managing time‑sensitive, deterministic networks such as Time Sensitive Networking, ARINC 664, Time Triggered Ethernet, or other approaches.
• Demonstrated expertise with Network/Precision Time Protocol and layer 2/3 networking (e.g., Ethernet, VLANs, QoS, IP, TCP/UDP, routing).
• Demonstrated functional understanding of common electrical digital and analog interfaces (Serial Bus Communications, Video, Audio, Ethernet, Analog Sensors).
• Excellent verbal, written, and graphical communication skills.
• Ability to earn trust, maintain positive and professional relationships.
• Strong ability and desire to analyze complex systems and deliver results‑oriented solutions.
• Ability to work collaboratively in a fast paced, dynamic work environment.

• M.S. in Aerospace, Mechanical, Systems, Software, Electrical, or related technical subject area.
• Experience with human‑rated spacecraft.
• Experience with full spacecraft design life cycle.
• Experience with developing and delivering integrated, space‑qualified Hardware/Software components. A solid hardware and software background is desired.
• Experience with network topologies, architectures, and design principles.
• Experience with spacecraft communication protocols (CCSDS).
• Experience with systems safety design practices.
