Home Assembly Jobs in Bothell, WA (NOW HIRING)

Shift: 7:00 AM – 3:30 PM

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

· Experience 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

· EPA Section 608 Certification (Universal preferred)

· 2+ years of hands-on experience with refrigeration/HVAC systems

· Comfort diagnosing electrical/mechanical issues and reading wiring diagrams
