Test Engineer

Test Engineer – Industrial Gas / Combustion Equipment Kent, WA

We are a leading provider of custom-engineered gas and energy systems, delivering high-performance solutions for industries ranging from energy and utilities to data centers and industrial processing. Our Gas Systems are the cornerstone of our business, specializing in complex, build-to-order equipment including pressure vessels, heat transfer systems, and integrated process skids.

Our team thrives at the intersection of engineering and manufacturing, designing innovative systems while staying closely connected to the shop floor to ensure everything we create is practical, manufacturable, and reliable in the field.

We are seeking a hands-on Test Engineer to join an established industrial equipment manufacturer in the Kent / South Seattle area.

This role is ideal for an engineer who enjoys figuring out how to answer difficult engineering questions through physical testing. You will own the testing process from defining the methodology and building the test setup through instrumentation, execution, data analysis, and final engineering conclusions.

You will work directly with vaporizer, burner, combustion, thermal, and pressurized-gas equipment in a lab and shop environment. This is not a test-technician, quality, or procedure-execution role. The Test Engineer is expected to determine what needs to be tested, how to test it safely and repeatably, and what the resulting data means for the product and engineering team.

Success in this role requires strong mechanical engineering fundamentals, sound technical judgment, comfort working around real hardware, and the ability to move fluidly between building a test rig, troubleshooting equipment, analyzing data, and documenting the results.

• Develop and document test plans and test methodologies for industrial gas, vaporizer, burner, and related products
• Determine what measurements and test conditions are required to answer engineering and product-performance questions
• Design, specify, build, and modify physical test stands, rigs, fixtures, and experimental setups
• Select and integrate instrumentation and data-acquisition equipment for pressure, flow, temperature, thermal performance, and other physical measurements
• Execute performance, feasibility, development, and validation testing
• Work safely around high-pressure gases, flammable gases, combustion systems, high temperatures, and other hazardous test conditions
• Establish safe and repeatable test procedures, including purge, pressure-relief, leak-checking, and related test-safety practices
• Troubleshoot unexpected equipment behavior and develop tests that help isolate root causes
• Reduce and analyze raw test data and translate the results into clear engineering conclusions
• Identify performance deviations and provide data that supports engineering design changes
• Prepare clear test procedures, reports, findings, and technical documentation
• Work from mechanical drawings, schematics, P&IDs, and related engineering documentation
• Perform hands-on rig assembly, instrumentation installation, and lab/shop troubleshooting
• Maintain and support test equipment, instrumentation, and data-acquisition systems
• Partner closely with product engineers, development engineers, technicians, and manufacturing personnel
• Support field validation, commissioning, and customer-site troubleshooting when needed

• Bachelor's degree in Mechanical Engineering or a related engineering discipline
• Approximately 3–5 years of relevant engineering experience
• Hands-on experience developing and executing physical engineering tests
• Experience independently developing test plans, methodologies, or experimental procedures
• Experience designing, building, or modifying test stands, test rigs, fixtures, or similar hardware
• Hands-on experience with instrumentation and data acquisition
• Experience measuring physical parameters such as pressure, flow, temperature, or thermal performance
• Experience testing mechanical, thermal, fluid, gas, combustion, propulsion, energy, or similarly complex physical systems
• Strong mechanical aptitude and comfort working directly with tools,…
