About The Position

Advanced TIG Welder & Fabricator (Hydrogen R&D – Contract) Joby Aviation is seeking an expert Advanced TIG Welder for a contract engagement within our Hydrogen R&D Team. This role is critical to the development of experimental hydrogen propulsion systems, focusing on the high-precision fabrication of specialized tubing, cryogenic components, and test fixtures. We are looking for a contractor who can execute high-integrity welds for flight-critical R&D applications where leak-proof precision is paramount

Requirements

Experience: 6+ years of professional TIG welding experience, specifically in high-stakes R&D (Aerospace, Motorsports, or High-Pressure Fluid Systems).
Tubing Mastery: Expert-level proficiency in TIG welding thin-wall tubing and various metals (Aluminum, Stainless, Chromoly, Titanium).
High-Integrity Welding: Proven ability to produce clean, x-ray quality welds; experience with 1G through 6G positions and technical GD&T callouts.
R&D Mindset: Ability to pivot quickly between projects as research priorities shift, maintaining extreme attention to detail.
Tools & Systems: Comfortable using Slack, Zoom, and digital ticketing (Jira/Kanban) to track and document R&D deliverables.

Nice To Haves

Helium Leak Testing: Familiarity with helium leak checking procedures and equipment to ensure vacuum-jacketed or high-pressure integrity.
Hydrogen/Cryo Experience: Experience welding cryogenic components or high-pressure fluid systems is a significant plus.
Exotic Metals: Proficiency with 321 Stainless Steel, 4140, and Titanium.
Standards: Familiarity with AWS D17.1 (Aerospace) or ASME B31.3 (Process Piping).
Availability: Willingness to work 9-hour days and overtime as hydrogen testing milestones require.

Responsibilities

Hydrogen Systems Fabrication: Execute ultra-high-precision TIG welding for experimental hydrogen tubing, manifolds, and cryogenic assemblies.
R&D Fixturing: Design and build custom, one-off jigs and test fixtures to support hydrogen hardware validation.
Engineering Partnership: Collaborate directly with Hydrogen R&D engineers to solve complex fluid-handling challenges and provide feedback on design for manufacturability (DFM).
Full Cycle Ownership: Independently manage R&D job requests, from initial setup and material prep to final TIG welding and post-process inspection.
Agile Prototyping: Rapidly iterate on prototype designs, identifying creative solutions for non-standard manufacturing problems in a fast-paced environment.
