Integration & Test Specialist

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
