Freelance Tank Design Engineer information

What is a freelance tank design engineer?

Freelance Tank Design Engineers are professionals who specialize in designing tanks for various applications, such as storage, processing, or transportation of liquids and gases, and work independently rather than as full-time employees for a single company. They typically provide services like creating technical drawings, performing stress and safety analyses, and ensuring compliance with industry standards. These engineers often work with clients from industries such as oil and gas, water treatment, and manufacturing, and may be responsible for managing multiple projects simultaneously. Their freelance status allows them flexibility in choosing projects and clients, but also requires strong project management and business skills.

What are the key skills and qualifications needed to thrive as a freelance tank design engineer?

To thrive as a Freelance Tank Design Engineer, you need expertise in mechanical or civil engineering, fluid dynamics, and structural analysis, usually backed by a relevant engineering degree and professional experience. Proficiency with CAD software (such as AutoCAD or SolidWorks), industry standards (like API 650 or ASME), and finite element analysis tools is typically required. Strong project management, problem-solving abilities, and client communication skills distinguish top performers in this field. These competencies are crucial for designing safe, efficient tanks that meet client specifications and regulatory requirements while managing projects independently.

How do freelance tank design engineers typically collaborate with clients and other engineering professionals during a project?

Freelance Tank Design Engineers often work closely with clients to understand specific requirements, such as capacity, materials, and regulatory standards. Collaboration usually involves regular virtual meetings, progress reports, and sharing design drafts for feedback. Additionally, they may coordinate with structural engineers, fabricators, and safety experts to ensure the design meets all functional and compliance needs. Strong communication skills and proficiency with design software are essential to maintain smooth collaboration throughout the project lifecycle.

What is the difference between Freelance Tank Design Engineer vs Mechanical Tank Design Engineer?

AspectFreelance Tank Design EngineerMechanical Tank Design Engineer
CredentialsTypically requires engineering degree, certifications varyRequires engineering degree, often professional licensure
Work EnvironmentIndependent, project-based, remote or on-siteCompany-based, office or plant setting
Industry UsageFreelance, consulting, project-specificFull-time employment, design departments
Search/Comparison IntentYes, often compared for project scope and flexibilityYes, for full-time roles and expertise

The main difference is that a Freelance Tank Design Engineer works independently on various projects, offering flexibility and diverse experience, while a Mechanical Tank Design Engineer is typically employed full-time within a company, focusing on ongoing design tasks within a structured environment.

Job description

Propulsion Engineer – Tank Test & Development

Houston, TX

About Intuitive Machines

Intuitive Machines is an innovative and cutting-edge space company making cislunar space accessible to both public and private customers. We believe our mission is to further research, communications, and exploration beyond low lunar orbit. With multiple NASA lunar missions in the making and additional private missions on our manifest, we pride ourselves in supporting NASA, our customers, and the nation in paving the way to return humans to the surface of the moon. Our world-class team includes experts in all spacecraft subsystems design, development, and test, on-orbit operations, and safety.

About the Role

We are seeking a Propulsion Engineer to support testing and development of propulsion system tanks across multiple spacecraft programs. This role is focused on executing acceptance and qualification testing of flight and development tanks, while working closely with structures, manufacturing, and propulsion teams to ensure safe, reliable hardware performance.

Tank hardware spans a wide range of applications, including cryogenic propellants, hypergolic systems, and high-pressure pressurant storage, across both metallic and composite designs.

This position may be filled at the Engineer or Senior Engineer level, with scope ranging from test execution and data ownership to technical ownership of tank hardware, test strategy, and certification activities based on experience and demonstrated capability.

Responsibilities:
  • Execute acceptance and qualification testing of propulsion tanks, including proof pressure, leak, structural, and functional testing
  • Develop and execute test procedures; perform and lead test setup, execution, and teardown in collaboration with technicians
  • Define test configurations, instrumentation, and data acquisition requirements for tank testing
  • Reduce and interpret test data; generate test reports, certification documentation, and data packages
  • Own data review against requirements and support disposition of nonconformances and anomalies
  • Support troubleshooting and real-time decision making during hazardous and high-energy testing operations
  • Participate in test readiness reviews, procedure reviews, and post-test data reviews
  • Maintain configuration control of tank hardware, test setups, and procedures
  • Coordinate closely with structures, stress, and manufacturing teams to ensure alignment between design intent, test results, and structural margins
  • Contribute to tank design iterations, verification planning, and system integration activities
Senior-Level Expectations (if applicable):
  • Serve as technical owner or Responsible Engineer for tank hardware or test campaigns
  • Define qualification and acceptance test strategies, including structural margins, test factors, and certification approach
  • Lead anomaly investigations and drive resolution across design, manufacturing, and test
  • Provide technical leadership in tank design, analysis correlation, and verification closure
  • Interface with program leadership, safety, and review boards for certification and readiness activities
Required Education / Experience / Skills:
  • Bachelor’s degree in Mechanical, Aerospace, or related Engineering discipline
  • Engineer level: 2–6 years of relevant experience
  • Senior level: Typically 10+ years of relevant experience with demonstrated ownership of pressure vessel or propulsion hardware
  • Experience working with hardware in a test, lab, or production environment
  • Experience writing or executing engineering test procedures
  • Ability to analyze and clearly communicate test data
  • Working knowledge of pressure systems, structural behavior, or fluid systems
  • Strong attention to detail, safety, and configuration control
Preferred / Differentiating Experience:
  • Experience with propulsion tanks or pressure vessels (metallic or composite, including COPVs)
  • Familiarity with cryogenic, hypergolic, or high-pressure gas systems
  • Experience with structural or pressure testing (proof, burst, fatigue, etc.)
  • Background working closely with structures or stress analysis teams
  • Experience with nonconformance disposition, failure investigation, and root cause analysis
  • Familiarity with aerospace standards (NASA, ASME, COPV design/test standards)
  • Experience supporting qualification, certification, or flight readiness reviews
  • Proficiency with MATLAB, Python, or similar tools
Essential Requirements:
  • Ability to work effectively in a collaborative, cross-disciplinary environment
  • Ability to support test campaigns, including off-hours when required
  • Strong organizational skills and communication
