This is a roll-up-your-sleeves role in which you'll prototype, build, and troubleshoot alongside world-class engineers. This role sits at the intersection of precision machining, electromechanical assembly, and innovative fixture design, supporting prototype builds as well as low-volume production. You will work closely with motor/generator engineers, fluid dynamicists, mechanical engineers and highly skilled electrical technicians to translate designs into robust, manufacturable hardware, ultimately ending in its deployment in the Node at sea. Candidates should have strong interpersonal skills and thrive in a creative, scrappy, and collaborative environment in which the best ideas change the company’s direction on a regular basis. If you are an excellent technician, regardless of your background, we want you to apply. We strive to be the best engineering team on the planet and we compensate our team accordingly. ## Responsibilities - Operate traditional machines such as mill, lathe, saws, shears, press brakes, rollers, drill presses, grinders, plasma cutters, and related fabrication equipment - Perform field-fit modifications, repairs, and rework on prototype and production hydro-turbine and generator subassemblies, precision rotating machinery, sealing interfaces, and related integration tooling - Support trial builds, teardowns, re-assembly and design iterations - Interpret and work from detailed manufacturing drawings and CAD models - Collaborate with design engineers to suggest manufacturability improvements - Design, fabricate, and validate custom assembly fixtures, jigs, and alignment tools - Utilize 3D printing for rapid prototyping of fixtures and mock-ups - Perform dimensional inspections using Vernier Calipers, micrometers, bore gauges, Dial indicators, height gauges etc. - Ensure compliance with tolerance stack-ups during assembly - Document assembly procedures, inspection reports, and deviations - Provide feedback on assembly challenges, tolerance feasibility and fixture effectiveness - Support prototype iteration cycles and root-cause analysis - Contribute ideas to improve build repeatability, safety, and efficiency Required Qualifications - 5+ years of hands-on experience in prototype fabrication, metal fabrication, welding, or a related trade - Demonstrated ability to fabricate one-off and low-volume assemblies from drawings, CAD models, sketches, and verbal direction - Working knowledge of GD&T and tolerance interpretation - Experience using 3D printing for functional prototyping or tooling - Strong written and verbal communication skills - Able to independently work on complex fixtures and assembly designs - Strong problem-solving and hands-on troubleshooting ability - High technical curiosity and a passion for learning - Innovative mindset, comfortable designing solutions when standard tools don’t exist - High attention to detail and craftsmanship - Strong organizational and interpersonal skills Desired Qualifications - 10+ years in a similar role - Experience operating and supporting multi-axis CNC machines for shafts, turbine runners, fixtures, tooling etc. - Proficiency in TIG and MIG welding, preferably with stainless steel, aluminum, and carbon steel - Experience fabricating, repairing, and finishing fiberglass components using molds, hand layup, vacuum bagging, resin systems, and composite bonding techniques - Experience assembling high-precision rotating machinery - Experience working alongside R&D teams in iterative development environments - Experience working on marine or offshore machinery - Experience working on subsea bearings, or hydrodynamic bearings, or hydrostatic bearings - Experience working on laser cutting and laser welding processes - Experience with instrumentation and controls (pressure transducers, thermocouples, RTDs, etc.) - Familiarity with NX/Teamcenter - Familiarity with materials and coatings for submerged or corrosive environments - Familiarity with magnetic components and magnet safety - Basic understanding of hydro turbines and electrical machines (stators, windings, insulation systems) The above qualifications are desired, not required. We encourage you to apply if you are a strong candidate with only some of the desired skills and experience listed. Additional Requirements - Travel to vendors and test sites as needed - Intermittently able to work longer hours and weekends to support critical needs. While we expect a lot of each other, we also offer a high degree of autonomy and work-life balance, including flexiblePTO and flexible working hours. ## Compensation and Benefits If hired for this full-time role, you will receive: - Cash compensation of $45-55/hour. - Equity in the company. We’re all owners and if we’re successful, this equity should be far and away the most valuable component of your compensation. - A benefits package that helps you take care of yourself and your family, including: - Flexible paid time off - Health insurance (the company pays 100% of gold-level PPO plan for full-time employees, their partners, and dependents) - Dental insurance (the company pays 100% for full-time employees, their partners, and dependents) - Vision insurance (the company pays 100% for full-time employees, their partners, and dependents) - Disability insurance (the company pays 100% for a policy to provide long-term financial support if you become disabled) - Ability to contribute to tax-advantaged accounts, including 401(k), health FSA, and dependent care FSA - Relocation assistance to facilitate your move to Portland (if needed).
