What does a Rocket Propulsion Engineer do?

A Rocket Propulsion Engineer designs, develops, tests, and improves propulsion systems that power rockets and spacecraft. They work with different types of propulsion technologies, such as liquid, solid, hybrid, and electric propulsion. Their responsibilities include analyzing performance, ensuring safety, and optimizing efficiency. These engineers collaborate with teams to create innovative solutions for space exploration, defense, and commercial applications.

What are some typical daily responsibilities of a Rocket Propulsion Engineer?

Rocket Propulsion Engineers spend their days designing, analyzing, and testing propulsion systems for rockets, including engines, fuel systems, and related subsystems. They collaborate closely with other engineers, such as structural and avionics specialists, to integrate propulsion solutions into the broader vehicle design. Daily tasks often involve running simulations, reviewing test data, troubleshooting technical issues, and participating in design or safety reviews. This role is usually a mix of hands-on experimental work and theoretical modeling, providing a dynamic and challenging work environment.

What are the key skills and qualifications needed to thrive in the Rocket Propulsion Engineer position, and why are they important?

To thrive as a Rocket Propulsion Engineer, you need a strong background in aerospace or mechanical engineering, thermodynamics, and fluid mechanics, typically supported by a relevant engineering degree. Familiarity with propulsion simulation software (like ANSYS or MATLAB), CAD tools, and knowledge of industry standards or certifications such as those from NASA or DoD are highly valued. Strong analytical skills, problem-solving abilities, and the capacity to work effectively in multidisciplinary teams are important soft skills. These attributes ensure precise design, safe testing, and innovative solutions in the highly technical and collaborative field of rocket propulsion.

Job description

ABOUT ROCKET LAB

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 to 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

Neutron is a medium lift launch vehicle capable of delivering the mega constellations of tomorrow, high assurance payloads, and human spaceflight. As a highly reusable launch platform, Neutron will deliver a highly cost-effective and reliable launch solution leveraging Rocket Lab's proven execution history with the Electron program. If you're interested in joining a high performing team, pushing the boundaries with a clean sheet development of re-usable liquid launch vehicle, this is your opportunity!

PROPULSION ENGINEER II – ARCHIMEDES ENGINE SYSTEMS

As an Engine Systems Propulsion Engineer, you will play a critical role in the development, testing, and operation of the Archimedes Engine family, a cornerstone of the Neutron rocket program. This highly technical role involves ownership of engine subsystems, test campaigns, data analysis, and refining designs for reliability and vehicle operations, while driving system architecture trades, managing interfaces, and optimizing requirements for the vehicle.

Success requires strong autonomy, technical expertise, curiosity, attention to detail, and the ability to organize complex systems into actionable plans while collaborating across teams. You will also support engine analysis, simulation, testing, and tool development, bringing deep technical acumen to solve challenging problems. As a self-starter capable of leading projects with minimal oversight, you will have the opportunity to make a significant impact in a fast-growing startup environment that fosters growth and innovation.

WHAT YOU'LL GET TO DO:

  • Design, analyze, test, fly, and refly next generation propulsion hardware ensuring operational readiness and flight success.
  • Develop clear requirements and deliver validated designs and hardware that meet program milestones and flight requirements.
  • Execute engine test plans, including performance validation and reliability testing, and conduct post-test data reviews to distill learnings and adjust test planning.
  • Collaborate with cross-functional teams to ensure robust integration, testing, and problem solving.
  • Support flight operations, including engine acceptance and post-flight analysis.

YOU'LL BRING THESE QUALIFICATIONS AS PROPULSION ENGINEER II:

  • Bachelor's degree in mechanical engineering, aerospace engineering, or related field.
  • 2+ years of experience in rocket engine development, testing, or operations.
  • Strong technical understanding of fluid dynamics, thermodynamics, and cryogenic systems.
  • Fundamental understanding of mechanical design principles.

THESE QUALIFICATIONS WOULD BE NICE TO HAVE:

  • Advanced degree in a fluid mechanics-heavy field.
  • Proven ability to conduct hotfire data reviews, identify blockers for testing, and ensure operational safety of engine systems.
  • Experience with staged combustion rocket engines and Methyl/LOX propellant systems.
  • Background in failure analysis, combustion dynamics, turbopump mechanics, and/ or fluid systems analysis.
  • Familiarity with reusable rocket engine systems and/or test/launch facility operations.

This position may require prolonged periods of sitting, standing, walking, computer work, and occasional exposure to moderate levels of noise, dust, and fumes in production areas

Level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience.

Base salary is just one component of our total rewards package at Rocket Lab. Employees may also receive company equity and access to a robust benefits package including: top tier medical HMO, PPO & a 100% company-sponsored medical HSA plan option, dental and vision coverage, 3 weeks paid vacation and 5 days sick leave per year, 11 paid holidays per year, flexible spending and dependent care savings accounts, paid parental leave, disability insurance, life insurance, and access to a 401(k) retirement plan with company match. Other perks include: Discounted employee stock purchase program, subsidized EV charging stations, onsite gym, food and drinks, and other discounts.

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.
