Senior Avionics Systems Architect - Flight Electronics

Castelion; Rio Rancho (NM); On-site; USD 140,000 - 180,000; Full time

Job summary

Castelion is seeking a Senior Avionics Systems Engineer to define and deliver the avionics architecture for long-range hypersonic strike vehicles. You will own integration of power, control electronics, sensors, embedded computing, and flight software in a fast-paced, hardware-driven environment.

You will mentor engineers, lead system-level trades, and collaborate with cross-functional teams to ensure reliability, testability, and mission success.

Qualifications

• Bachelor's, Master's, or PhD in Electrical Engineering or related field.
• 8+ years of experience designing and integrating avionics or other high-reliability embedded electronic systems for aerospace or defense applications.
• Experience with schematic capture and PCB design using Altium Designer or equivalent ECAD tools.
• Strong understanding of EMI/EMC, grounding, shielding, and electrical reliability considerations for aerospace systems.
• Experience leading the development and integration of complex avionics systems from concept through qualification and flight testing.
• Familiarity with common aerospace interfaces and communication protocols (SPI, I2C, UART, CAN, Ethernet, RS-422/485, LVDS).

Responsibilities

• Define and maintain avionics system architecture for flight vehicles, including power distribution, communications, grounding, interfaces, and system integration.
• Lead integration of avionics subsystems, including flight computers, sensors, power electronics, control electronics, RF systems, flight termination systems, and propulsion electronics.
• Develop system-level requirements, interface definitions, wiring architectures, and integration documentation.
• Work with electrical, mechanical, software, GNC, propulsion, and manufacturing teams for seamless integration.
• Lead system-level hardware integration, bring-up, debugging, and troubleshooting during development and flight vehicle assembly.
• Define electrical design standards, component selection guidelines, and best practices for high-reliability flight electronics.
• Support design reviews and make system-level technical trades to optimize performance, reliability, manufacturability, and testability.
• Develop and execute integration, qualification, and flight test plans, translating results into system-level improvements.
• Mentor electrical engineers across multiple disciplines and contribute to best practices.
• Partner closely with program leadership to make technical trades aligned with mission success.
