Principal Avionics Engineer

Who We Are:
Venus Aerospace is revolutionizing rocket engine propulsion. With the first generational leap in rocket engine technology since Apollo, our proprietary Rotating Detonation Rocket Engine and Venus Detonation Ramjets deliver historic efficiency and performance across aerospace applications. We are building the next generation of propulsion platforms that enable breakthrough capabilities in space, defense, and commercial high-speed flight. Our team thrives on solving the toughest engineering challenges and pushing the boundaries of what’s possible in aerospace. At Venus, we’re looking for bold engineers and innovators who want to make history and redefine the future of propulsion.

 

The Role: Principal Avionics Engineer 
Join us as a Principal Avionics Engineer and help design, build and flight test revolutionary propulsion technology. You’ll lead the design and integration of flight computers, sensors, power systems, and communication interfaces; owning everything from architecture to flight test support. This role blends engineering leadership, hands‑on engineering, hardware‑in‑the‑loop testing, and cross‑disciplinary collaboration to deliver reliable, flight‑ready systems. If you excel at systems thinking, solving hard problems, and driving technical leadership, you’ll thrive here. 

Design, build and fly your systems! 

Lead the architecture, design, and selection of avionics hardware, including flight computers, sensors, power systems, and communication interfaces. 

Assess system risks and recommend mitigations 

Define and implement interfaces between flight components (e.g., flight computers, sensors, actuators, power systems, radios). 

Develop and maintain hardware-in-the-loop (HITL) test environments to support software development, integration, and verification. 

Own battery sizing and power system analysis, including load analysis, margins, thermal considerations, and mission profiles. 

Support system integration, ground testing, and flight testing, including troubleshooting and root cause analysis. 

Collaborate with external vendors and suppliers to define requirements, evaluate components, manage technical trade studies, and support procurement. 

Author and review technical documentation, including requirements, interface control documents (ICDs), schematics, test plans, and verification reports. 

Ensure avionics designs meet aerospace standards, reliability, safety, and environmental requirements. 

Mentor junior engineers and provide technical leadership across avionics and flight systems teams. 

Collaborate with Flight Software, GN&C, Aerodynamics, and Structures engineering disciplines to ascertain system requirements and meet technical program needs. 

Collaborate with Manufacturing and Quality to ensure your systems are ready to fly. 

Bachelor’s degree in Electrical Engineering, Aerospace Engineering, or related field (Master’s preferred). 

10+ years of experience in avionics or aerospace electrical systems engineering. 

Extensive experience in rocket propulsion, flight test and launch. 

Proven experience in systems design and architecture and requirement writing 

Proven experience with flight computer hardware design and/or selection. 

Strong background in hardware-in-the-loop (HITL) testing and integration. 

Hands-on experience defining and implementing interfaces between flight components. 

Demonstrated experience with battery sizing, power budgets, and power system design. 

Experience working with and managing outside vendors, including technical evaluations and supplier coordination. 

Proficiency reading and creating schematics, wiring diagrams, and interface documentation. 

Strong troubleshooting and systems-level thinking skills. 

Experience with environmental testing and qualification. 

Key Competencies: systems-level avionics expertise; cross-functional collaboration; vendor and supplier management; technical leadership and mentorship; clear technical communication 

Experience with DO-160, DO-254, DO-178, or similar aerospace standards. 

Familiarity with embedded systems, buses and protocols (CAN, UART, SPI, I2C, Ethernet, MIL-STD-1553, etc.). 

Experience managing contractors for consulting or hardware production 

Experience supporting flight test campaigns. 

Background in launch vehicles, missiles, propulsion systems, space systems, eVTOL, UAV or experimental aircraft.
