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
