Senior Avionics Hardware Engineer - Electron

ABOUT THE ROLE

Rocket Lab is seeking an experienced Electronics/Avionics Engineer to join our Electron Avionics team. You'll develop PCBs and avionics systems for flight hardware, working through the complete development cycle - from requirements and schematic capture to environmental testing, production support, and launch operations.

This hands-on role combines deep technical work with broad system exposure. You'll work across Electron's complete avionics architecture: flight computers, electric turbo-pump motor controllers, thrust-vector control systems, sensor networks, flight termination systems, and high-voltage battery packs. You'll debug complex hardware issues, improve circuit fault tolerance, optimise designs for manufacturing, and build expertise that spans the entire vehicle.

YOU'LL GET TO:

Own & Ship:

• Own avionics hardware through the full lifecycle - from requirements and schematic capture to layout, PCBA bring-up, mechanical integration, testing, and production
• Develop PCB designs spanning high-voltage powertrain components and flight computers through to critical analogue sensing circuits
• Prepare and release manufacturing documentation and create and maintain design libraries
• Take full accountability for deliverables from concept to deployment

Solve & Fix:

• Debug complex electronics issues at board and system level using laboratory equipment and custom test fixtures
• Conduct electrical and reliability analyses, including worst-case, power budgets, thermal derating, signal integrity, FMECA, and root-cause investigations
• Support orbital and HASTE launch operations as the avionics delegate, covering troubleshooting, system health monitoring, and real-time investigations

Build & Improve:

• Lead hands-on bring-up and verification, including environmental testing (TVAC, shock, vibration, EMI/EMC)
• Develop the test and automation infrastructure used to verify avionics hardware
• Review and approve engineering changes and design documentation, and maintain schematics, BOMs, test reports, and design justification records
• Optimise designs for manufacturing and improve circuit fault tolerance

Lead & Scale:

• Set the technical standard for avionics hardware, leading design reviews and mentoring junior engineers
• Review and approve engineering changes, schematics, PCB designs, and other technical documentation
• Provide technical leadership and guidance across the avionics team

Grow & Deliver:

• Build deep expertise across the complete avionics architecture of a launch vehicle
• Drive tasks and projects to completion independently
• Rapidly learn complex systems and apply engineering fundamentals to solve problems

YOU'LL BRING THESE QUALIFICATIONS:

Core requirements:

• Bachelor's degree in Electrical, Electronics, or Mechatronics Engineering, or demonstration of exceptional ability
• 4+ years hands-on experience developing reliable electronics
• Strong foundation in electronics fundamentals: power electronics, analogue, digital, and mixed-signal circuit design, signal integrity, and grounding principles
• Proficient with schematic capture and PCB layout tools such as Altium (preferred) or KiCAD, and circuit simulation tools (LTspice, SPICE, or equivalent)
• Hands-on experience with laboratory equipment (power supplies, oscilloscopes, electronic loads, DMMs, function generators, spectrum analysers, process calibrators) to verify hardware functionality

BONUS POINTS FOR:

• Skilled in board layout best practices, including layer stackup, component placement, and low-noise design to minimise EMI/EMC
• Sound understanding of design for manufacturability, assembly, and test, and of electronics manufacturing processes
• Experience with high-reliability or flight hardware, and designing to ECSS, NASA, or IPC standards
• Experience taking hardware through testing and qualification (vibration, shock, thermal, EMC), with familiarity with common electronics failure modes
• Knowledge of digital communication interfaces (RS-422, RS-485, SPI, IC, CAN bus, Ethernet), including physical layer design and debugging
• Familiarity with motor drives, power distribution, or battery management systems
• Experience with embedded systems and hardware/software integration
• Experience with sensor interfacing and signal conditioning (e.g. 4-20mA sensors, RTDs, thermocouples, strain gauges, accelerometers, pressure transducers)
• Comfortable with Python for test and automation tasks
• Understanding of requirements management and configuration control in regulated or high-reliability environments

EXPECTATIONS

• Ownership mentality with the ability to drive tasks and projects to completion independently
• Thrive in ambiguous, fast-changing environments where requirements evolve rapidly
• Balance speed with quality - move quickly while maintaining appropriate rigour
• No task is beneath you - roll up your sleeves and do what's needed for mission success
• Bias for action - prioritise getting hands on, building and testing hardware to get results early
• Demonstrate professionalism, punctuality, and adherence to company policies
• Ensure health and safety policies and procedures are followed at all times

ADDITIONAL INFORMATION

• Domestic and international travel may be required
• Additional duties as reasonably required
• Adherence to company policies and procedures is expected

WHAT TO EXPECT

We're on a mission to unlock the potential of space to improve life on Earth, but that's not an easy task. It takes hard work, determination, relentless innovation, teamwork, grit, and an unwavering commitment to achieving what others often deem impossible. Our people out-think, out-work, and out-pace. We pride ourselves on having each other's backs, checking our egos at the door, and rolling up our sleeves on all tasks big and small. We thrive under pressure, work to tight deadlines, and our focus is always on how we can deliver, rather than dwelling on the challenges that stand in the way.

Note: We're looking for practical engineers who can move between deep design work and hands-on problem solving. Aerospace experience is not required. If you've developed reliable, mission-critical electronics in other high-consequence industries, we'd like to talk.
