How much do internship combustion engineer jobs pay per hour?

As of Jun 9, 2026, the average hourly pay for internship combustion engineer in the United States is $25.42, according to ZipRecruiter salary data. Most workers in this role earn between $20.67 and $28.85 per hour, depending on experience, location, and employer.

What does an Internship Combustion Engineer do?

An Internship Combustion Engineer assists in researching, designing, and testing combustion systems, such as engines or industrial burners. Interns typically work under the supervision of experienced engineers to collect data, analyze performance, and help improve energy efficiency and emissions. They may also participate in laboratory experiments, simulations, and report writing. This role provides hands-on experience and exposure to various combustion technologies and industry practices.

What is the difference between Internship Combustion Engineer vs Junior Mechanical Engineer?

AspectInternship Combustion EngineerJunior Mechanical Engineer
Required CredentialsTypically pursuing or holding a degree in Mechanical or Chemical EngineeringBachelor's degree in Mechanical Engineering or related field
Work EnvironmentInternship setting, often in power plants, manufacturing, or energy sectorsEntry-level position in engineering firms, manufacturing, or industrial plants
Employer & Industry UsageUsed in energy, power generation, and manufacturing industriesCommon across various engineering sectors including automotive, aerospace, and manufacturing

Internship Combustion Engineers are typically students or recent graduates gaining practical experience in combustion systems, while Junior Mechanical Engineers are entry-level professionals working on broader mechanical projects. Both roles require relevant engineering education, but internships focus on training and exposure, whereas junior roles involve more responsibility and project involvement.

What are the key skills and qualifications needed to thrive as an Internship Combustion Engineer, and why are they important?

To thrive as an Internship Combustion Engineer, you need a solid understanding of thermodynamics, combustion principles, and mechanical or chemical engineering fundamentals, typically supported by progress toward a relevant engineering degree. Familiarity with simulation tools such as ANSYS Fluent, MATLAB, and data acquisition systems is often required. Strong analytical thinking, problem-solving ability, and effective teamwork skills help interns stand out in this field. These skills ensure accurate analysis, effective project contributions, and smooth collaboration within engineering teams working on complex combustion systems.

What types of projects and responsibilities can an Internship Combustion Engineer expect to work on during their internship?

As an Internship Combustion Engineer, you can expect to work on projects involving engine testing, fuel analysis, emissions measurements, and data analysis to support the development of efficient combustion systems. Interns often assist with setting up experiments, collecting and interpreting test results, and collaborating with senior engineers on research and development tasks. You'll typically work in a team environment, gaining hands-on experience with lab equipment and software tools commonly used in combustion engineering. This role provides valuable exposure to real-world engineering challenges, and successful interns often have opportunities to present findings and contribute to process improvements.

Job description

At Relativity Space, we're building rockets to serve today's needs and tomorrow's breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that's just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.

Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven't been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you're in propulsion, manufacturing, software, avionics, or a corporate function, you'll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we're writing together. Now is a unique moment in time where it's early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.

About the Team:

The Propulsion team at Relativity is focused on developing and delivering highly performant and manufacturable engines for Terran R. Engineers are responsible for the entire lifecycle of their parts, from initial design through production to qualification and flight. The team fosters a culture of bottoms-up decision-making, free from technical gatekeeping, where ownership and accountability are key at all levels. But designing engines with a quarter million pounds of thrust is just the beginning. As the flight configuration enters qualification, the team is now exploring modifications for future engines, including thrust upgrades, new cycles, and design for mass production.

About the role:

  • Contribute to design and qualification of combustion devices hardware (injectors, thrust chamber, heat exchangers, igniters) through Computational Fluid Dynamics Analysis
  • Review test and flight data as necessary to evaluate and anchor models
  • Interface with hardware designers and utilize thermofluid expertise to influence design decisions
  • Develop and recommend analysis approaches that may decrease design iteration time
  • A strong commitment to accountability, collaboration, and execution

About you:

  • Bachelor's degree in a science or engineering field
  • Experience in performing computation fluid dynamics analyses (employment, internships, project experience)
  • Familiar with typical analysis steps including pre/post-processing, meshing, boundary conditions, etc.
  • Experience with basic engineering scripting in Python, MATLAB, or similar
  • Strong background in fluid mechanics and heat transfer

Nice to haves, but not required:

  • We believe varied perspectives & backgrounds strengthen our team. Prior experience in aerospace is not required
  • Graduate degree in a science or engineering field
  • Experience in Siemens STAR-CCM+
  • Working knowledge of rocket engine subsystems, such as combustion devices

At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job-related factors.
Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more! To see some of the benefits & perks we offer, please visit here.

Hiring Range:
$90,000—$124,500 USD

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.

If you need a reasonable accommodation, please contact us at accommodations@relativityspace.com.
