Principal Avionics Engineer - Neutron

Rocket Lab
Auckland, NZ Full Time Negotiable Sep 11, 2026

About the Job

We’re building Neutron, a medium lift, reusable launch vehicle designed for constellation deployment, interplanetary missions, and human spaceflight. It's the most ambitious programme in our history, and the avionics that fly it are being designed, built, and tested in house and we are looking for a Principal Engine...

The Neutron Avionics team owns every avionics system on the vehicle. Flight computers, power distribution, sensing, comms, and the flexible harness assemblies that tie it all together. Almost all of it is developed and produced internally, which means the people who design it also see it fly.

As Principal Avionics Engineer, you are the technical authority for avionics hardware, circuit design, PCB layout, and test strategy and coverage. This is a hands on technical leadership role with no direct reports, your influence comes from your engineering judgement, your ability to solve problems nobody has solve...

Lead root cause analysis on anomalies and failures, and make sure the fix sticks
Lead small teams through significant engineering challenges
Assess emerging technologies and shape the avionics technology pipeline and development strategy

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.
