About this role

What you'll be doing

As an Integration & Test Specialist at Endurance Energy, you will work alongside mechanical, fluids, and electrical engineers to assemble, plumb, instrument, and test complex systems under real-world conditions.

You will be responsible for taking subsystems from parts to fully integrated hardware, pressure-tight, leak-free, instrumented, and ready for test. You will play a key role in debugging integration issues, improving build processes, and ensuring systems are safe and robust before deployment.

You are expected to operate with high ownership on the floor: driving build quality, identifying issues early, and pushing systems to readiness without waiting for direction.

This is a critical position where your speed, precision, and judgment directly impact our ability to hit hardware milestones on aggressive timelines.

Key Responsibilities

  • Assemble mechanical and fluid systems including pressure vessels, piping, valves, and heat exchangers

  • Perform tubing and piping integration including routing, bending, cutting, and fitting

  • Execute high-quality plumbing of test systems and subsea hardware (Swagelok, compression fittings, welded systems, etc.)

  • Install sensors, instrumentation, and support hardware for test readiness

  • Perform pressure testing, leak checking, and system validation (hydrostatic and pneumatic)

  • Support system bring-up and debugging alongside engineering teams

  • Read and interpret engineering drawings, P&IDs, and assembly documentation

  • Identify and resolve fit-up, tolerance, and integration issues in real time

  • Drive clean, organized, and repeatable build processes on the floor

  • Document builds, test setups, and issues for engineering and QA traceability

  • Support rapid prototyping and iteration under tight timelines

  • Maintain a safe working environment when operating high-pressure and high-temperature systems

Qualifications

  • 5+ years of hands-on experience in mechanical assembly, fluid systems, or integration roles

  • Demonstrated experience assembling and testing complex mechanical or fluid systems

  • Strong experience with tubing, piping, fittings, and fluid system integration

  • Ability to read and interpret mechanical drawings and P&IDs

  • Experience with pressure testing, leak detection, and system validation

  • Strong mechanical intuition and ability to troubleshoot integration issues quickly

  • High attention to detail and craftsmanship in assembly work

  • Track record of working effectively in fast-paced, prototype-driven environments

  • High ownership mindset and ability to operate independently with minimal supervision

  • Strong communication skills and ability to work closely with engineers

Preferred Skills

  • Experience with orbital tube welding and/or other high-reliability welding processes

  • Background in high-pressure systems, process piping, or thermal systems

  • Experience in marine, subsea, aerospace, or energy hardware environments

  • Familiarity with Swagelok or equivalent fluid system standards and best practices

  • Light fabrication and manual machining experience (lathe, mill, drill press)

  • Experience supporting test operations and building custom test infrastructure

  • Familiarity with cleanliness standards and contamination control for fluid systems

  • Ability to contribute to fixture design and integration tooling
