Internship Combustion Engineer information

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 CesiumAstro, we are developers and pioneers of out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We take pride in our dynamic and cross-functional work environment, which allows us to learn, develop, and engage across our organization. If you are looking for hands-on, interactive, and autonomous work, CesiumAstro is the place for you. We are actively seeking passionate, collaborative, energetic, and forward-thinking individuals to join our team.
We are looking to add a Combustion Devices Engineer II to our team. In this role, you will work across the full hardware lifecycle from early concepts and CAD models through manufacturing, test execution, and design iteration.
JOB DUTIES AND RESPONSIBILITIES
  • Design and develop a variety of combustion devices of liquid rocket engine, combustion chambers, pre-burners, igniters. Create models and drawings of parts and assemblies. Perform calculations and analyses with team support.
  • Create schematics and document processes.
  • Own requirements definition, architecture trades, and system-level integration for assigned subsystems.
  • Work with manufacturing team to create finished engine parts. Support parts through 3d-printing, machining, post processing, and inspection. Incorporate feedback to improve design for manufacturing.
  • Develop and execute test programs, analyze experimental data, and apply findings to optimize designs.
  • Collaborate across mechanical, aerospace, and controls engineering teams to deliver flight-ready hardware.

JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS
  • Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related field.
  • 2+ years of experience with mechanical design, development, fabrication, assembly, or test (internships included)
  • Strong proficiency in CAD tools (Siemens NX, SolidWorks) - the ability to model complex three-dimensional geometry of the combustion chamber cooling channel.
  • Familiarity with aerospace safety and reliability practices.
  • Excellent written and verbal communication skills.
  • Ability to work as a teammate and independently to achieve ambitious goals.

PREFERRED EXPERIENCE
  • Prior experience designing of liquid rocket engine, combustion chambers, pre-burners, igniters or other rocket systems.
  • Practical experience in test bench setup and performance diagnostics.
  • Hands-on engineering (Full-stack: computer to wrench to broom).
  • Geometric dimensioning and tolerancing (GD&T).
  • Experience in a start-up or rapid development environment.
  • Experience with tools such as ANSYS and MATLAB.
