What are the key skills and qualifications needed to thrive as a Fluids Engineer, and why are they important?

To thrive as a Fluids Engineer, you need a solid background in fluid mechanics, thermodynamics, and mathematics, typically supported by a degree in mechanical, chemical, or petroleum engineering. Familiarity with simulation software like ANSYS Fluent or COMSOL, as well as relevant industry certifications, is often required. Strong analytical thinking, problem-solving abilities, and effective communication skills help Fluids Engineers excel in collaborative and technically challenging environments. These skills are vital for accurately modeling fluid behavior, ensuring system safety, and delivering efficient engineering solutions.

What are some common challenges faced by Fluids Engineers in cross-disciplinary project teams?

Fluids Engineers often work alongside mechanical, civil, and chemical engineers, which can present challenges in aligning diverse technical perspectives and priorities. Effective communication is essential, as each discipline may use different terminology or have unique design constraints. Additionally, balancing project timelines and integrating fluid dynamics solutions with broader system requirements can require adaptability and proactive problem-solving. Building strong collaborative relationships and staying open to feedback are key strategies for overcoming these challenges.

What are Fluids Engineers?

Fluids Engineers are professionals who specialize in the study and application of fluid mechanics, which involves the behavior of liquids and gases. They design, analyze, and optimize systems where fluids play a critical role, such as pipelines, pumps, turbines, and hydraulic systems. Fluids Engineers work in various industries, including oil and gas, aerospace, automotive, and manufacturing, to ensure efficient and safe transport and control of fluids. Their work often involves simulation, modeling, and testing to solve complex engineering challenges.

What is the difference between Fluids Engineer vs Mechanical Engineer?

AspectFluids EngineerMechanical Engineer
Required CredentialsBachelor's in Mechanical, Aerospace, or Civil Engineering; specialization in fluid dynamicsBachelor's in Mechanical Engineering; broad engineering fundamentals
Work EnvironmentResearch labs, aerospace, energy, and fluid systems industriesManufacturing, automotive, aerospace, and product design
Industry UsageFocus on fluid behavior, flow analysis, and hydraulicsDesign and analyze mechanical systems, including thermal and structural components

Fluids Engineers specialize in fluid dynamics, working primarily on fluid systems and flow analysis, often within aerospace, energy, or research sectors. Mechanical Engineers have a broader scope, covering various mechanical systems, including thermal, structural, and fluid components. Both roles require strong engineering fundamentals, but Fluids Engineers focus more on fluid-specific applications.

Job description

About the Team: 

The Factory Test team designs, builds, and operates the infrastructure needed to test nearly every part of Terran R right here at our headquarters in Long Beach, CA. This centralized approach provides engineers and technicians with exposure to the entire product lifecycle across a wide range of part sizes and complexities. The scope and scale are significant, with test stands capable of handling millions of pounds of force. Team members lead multiple projects in parallel, avoiding silos and gaining broad technical experience without needing a background in aerospace. With high-impact campaigns ahead, now is the time to join. You won't just execute, but you'll help shape and scale the test infrastructure required to meet the demands of a rapidly growing launch program.

About the Role:

  • As a Test Systems Engineer, you will own 1 or more test systems or test campaigns supporting development of Terran R components at our facility in Long Beach, CA. As a system owner, you will design, analyze, and operate automated fluids systems. Teamwork and communication skills are critical, as you will work cross-departmentally to ensure your systems meet the test requirements of the component designer. Examples of your tasks may include:
  • Designing test systems including their mechanical, fluid, and electrical components
  • Commissioning new test assets and systems
  • Completing, presenting, or reviewing fault tolerance analysis
  • Planning and executing test campaigns

About You:

  • Bachelor's degree in Mechanical Engineering, Mechatronics Engineering, Chemical Engineering, Process Engineering, or similar
  • Knowledge of fluid and thermodynamic first principles
  • Demonstrated experience designing systems to engineering requirements
  • Demonstrated working knowledge of systems operations
  • Ability to concisely communicate technical topics to audiences of many different backgrounds

Nice to haves but not required:  

  • Experience writing sequences or other software
  • Familiarity with cryogenics
  • Understanding of structural design principles
  • Delivery of systems compliant with ASME B31.3 & BPVC
  • Willing to work at heights, in confined spaces, in a dirty environment, and away from your desk
  • No previous aerospace experience is required for this position
