Welding & Fabrication Specialist

About the role

You will own the execution of critical welding and fabrication tasks that directly enable the construction of the world's first modular subsea geothermal power plants. This role requires you to develop and refine welding processes for advanced materials in a demanding marine energy context. You will be responsible for transforming engineering designs into tangible, high-integrity components that can withstand extreme ocean conditions. The position places you at the forefront of a deep-ocean energy deployment, working on hardware that defines a new category of power generation. You will collaborate daily with engineers to solve complex fabrication challenges and ensure rapid prototyping success. Your work will support the launch of a long-term demonstration project this fall, requiring precision and reliability. Ultimately, you will help convert vast thermal resources under the ocean into gigawatts of baseload power through hands-on shop excellence.

Key facts

What you'll do

• TIG welding of Inconel, stainless steel, and titanium for critical subsea components.

• Have experience fabricating or repairing components for marine, aerospace, or power generation systems that operate in harsh environments.
• Prove ability to fit, tack, and weld complex multi-material assemblies while meeting tight tolerances.
• Demonstrate hands-on familiarity with fabrication tools, machining operations, and precision measurement instruments.
• Understand weld metallurgy, joint design, and distortion control specifically for nickel and titanium alloys.
• Comfortably read and interpret detailed engineering drawings and weld symbols, with AWS D17.1 / ASME Section IX experience preferred.
• Apply knowledge of purging techniques, filler material selection, and heat input control to produce corrosion-resistant weldments.
• Maintain a track record of keeping a clean, organized, and safe fabrication environment at all times.
• Show commitment to safety and continuous improvement in every shop practice and procedure.
• Thrive in a fast-paced, prototype-driven environment where designs evolve rapidly and adaptability is essential.
• Communicate effectively and document processes to support engineering traceability and QA review.

Nice to have

• Experience welding pressure vessels or process piping for 10,000 psi systems.
• Familiarity with ASME code work or WPS/PQR development in close collaboration with engineers.
• Background in aerospace, energy, or marine fabrication environments that demand rigorous standards.
• Capability to perform visual and dye penetrant inspections to verify weld integrity.
