Job description

ABOUT ROCKET LAB

Rocket Lab is the end-to-end space company building rockets, spacecraft, and critical subsystems that keep the world connected, protected, expand humanity's reach to the Moon, Mars, and beyond. We move fast, build real hardware for meaningful missions, and make the impossible routine. Come shape the future with us.

SPACE SYSTEMS

At Rocket Lab, we're not just launching rockets — we're building the future of space. Our Space Systems team builds everything from complete spacecraft, precision payloads to the components and subsystems that allow them to thrive in space, like solar panels, flight software, star trackers, optical systems, separation systems, radios, and more.

Our Space Systems team has enabled more than 1,700 missions, ranging from interplanetary exploration, in-space manufacturing to national security and defense initiatives. The team has built spacecraft, payloads, and components for missions to the Moon and Mars, working with partners including NASA, the Space Development Agency, and the U.S. Space Force.Whether it's a single high-performance spacecraft, constellation, or the vertically integrated components that help them get to space — our world class Space Systems team is empowering some of the boldest and most ambitious space missions.

PRINCIPAL FLIGHT SOFTWARE ENGINEER

Based out of Rocket Lab's global headquarters in Long Beach, CA, thePrincipal Flight Software Engineer will play a key role in supporting the development of flight software for our Space Systems programs. You'll spend your days participating in all aspects of software design and development, from requirements definition through coding and testing. And when we say test, we mean your software will be on orbit within weeks and months, not years. Thanks to having our own rockets and launch sites, we have frequent opportunities to test and operate our software on orbit.

This role is for someone who wants to see their software make a big impact on the way we explore space and use it as a platform for discovery and innovation.

WHAT YOU'LL GET TO DO:

• Develop application software to run within a Real Time Operating System (RTOS) and/or embedded Linux
• Develop hardware drivers to interface to Inertial Measurement Units (IMUs), Star Trackers, Reaction Wheels and other spacecraft sensors and actuators
• Develop and maintain comprehensive unit tests to run within a Continuous Integration framework
• Collaborate with hardware-in-the-loop test engineers to verify and validate combined software and hardware functionality
• Collaborate with systems engineers and embedded systems engineers in developing, documenting and validating requirements
• Participate in review of source code changes and ensure all changes meet company coding standards
• Participate in design reviews such as a PDR and CDR
• Assist with on-orbit (and interplanetary!) flight operations

YOU'LL BRING THESE QUALIFICATIONS:

• Bachelor's degree in engineering (software, computer, electrical, aerospace, or other technical engineering discipline)
• 12+ years ofdemonstrated applicable experience in embedded software development
• Proficiency in Rust, C++, and C languages
• Experience with Real Time Operating Systems (RTOS) or with Embedded Linux
• Experience leading junior software developers, collaborating with other engineering disciplines, and interacting with customers
• Active Security clearance OR ability to obtain and maintain one
• U.S citizenship is required, due to program requirements

THESE QUALIFICATIONS WOULD BE NICE TO HAVE:

• Master's or PhD in engineering (software, computer, electrical, aerospace, mechanical, or other technical engineering discipline)
• Experience developing software and drivers with CAN/CAN-FD and/or UDP/TCP within an embedded system
• Experience developing software for autonomous vehicles operating in harsh environments

Anticipated annual equity grant value is designed around function, level, experience, and other factors; realized value depends on vesting and stock-price performance.

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.
