Senior Flight Software Engineer - Neutron

Rocket Lab is an end-to-end space company delivering responsive launch services, complete spacecraft design and manufacturing, payloads, satellite components, and more – all with the goal of opening access space. The rockets and satellites we build, and launch enable some of the most ambitious and vital space missions globally, supporting scientific exploration, Earth observation and missions to combat climate change, national security, and exciting new technology demonstrations.

Our Electron rocket has become the second most frequently launched U.S. rocket annually and has delivered more than 230 satellites to orbit, all while we work to develop Neutron, our upcoming medium-lift, reusable launch vehicle for larger constellation deployment. Our Space Systems business designs and builds our extensive line of satellites, payloads, and their components, including spacecraft that have been selected to support NASA missions to the Moon and Mars and components used on the James Webb Space Telescope.

Neutron

Rocket Lab's Neutron team is responsible for bringing our new large rocket Neutron and its launch and test sites to life. From designing and testing Neutron's structures and components, to firing up its new Archimedes engines, to setting up Neutron's launch pads and test sites across the United States, joining the Neutron team is your opportunity to help launch a new large rocket for the very first time.

Senior Flight Software Engineer – Neutron

As a Senior Flight Software Engineer based at Rocket Lab's Auckland, New Zealand site, you will support the development of the next-generation Command & Data Handling system for the Neutron launch vehicle. In this role, you will work across the full software stack to build core flight software, simulation frameworks, and development tools that enable mission-critical applications. To be successful, you must be a proactive problem-solver with strong technical judgment, a collaborative mindset, and a passion for building reliable systems that fly. Join a driven team of pioneers relentlessly tackling challenging projects, delivering on the impossible, and making an impact on the future of space!

What You'll Get To Do

• Develop core C++ flight software for the Neutron launch vehicle across embedded and application layers
• Build and maintain simulation frameworks for end-to-end mission validation and HITL integration
• Create Python-based tools, including code generators and data-analysis utilities
• Lead or contribute to architecture trades, design reviews, and backlog refinement
• Support the full software lifecycle—from planning and implementation to deployment of operational software
• Deliver high-impact engineering projects spanning multiple teams and disciplines

You'll Bring These Qualifications

• Degree in Computer Science, Electrical/Computer Engineering, or equivalent
• 5+ years of experience developing modern C++ and/or embedded software
• Experience with Python or similar scripting languages
• Experience with CI/CD, deployment tooling, Git, and issue tracking systems
• Demonstrated success working in fast-paced environments with shifting priorities

These Qualifications Would Be Nice To Have

• Experience with highly reliable or safety-critical software systems
• Background in requirements-driven software design
• Strong mathematical foundation
• Experience with machine learning
• Experience developing simulation software for control or physical systems (e.g., rockets, UAVs, autonomous vehicles)
