Tool and Die Maker

Subcritical Systems, Inc. is a venture-backed startup in Austin, Texas building the accelerator driven systems and the only US commercial manufacturer of accelerator cavities. What Space X did for rockets, we plan to do for accelerator cavities and commercialize across applications of power production, medical isotopes, semiconductors and waste transmutation. We are in the process of building the Energy Amplifier — a novel nuclear fission system in which a particle accelerator drives a subcritical core, making meltder physically impossible for clean power production. Due to its inherent safety, our system has a more streamlined licensing process. Our founding team includes successful entrepreneurs with a track record of building several multibillion dollar companies in deep-tech, and scientists who were leading U.S. national labs with deep experience in accelerator & nuclear technologies. We are actively hiring to expand our team as we work toward licensing, regulatory submissions, and construction of our first energy amplifier. More information is available at subcritical.com. ROLE SUMMARY We are seeking a hands-on experienced Tool and Die Maker for building and troubleshooting precision metal parts, cutting tools, jigs, fixtures, and dies used to produce precision components for SSI’s Energy Amplifier. KEY RESPONSIBILITIES Reading Technical Blueprints: interpreting complex engineering drawings, 3D CAD models, and mathematical specifications. Machining and Operating Machine Equipment: use manual and computer-controlled (CNC) tools such as lathes, mills, grinders, and electrical discharge machines (EDM) to create precision components from metals and plastics. Fitting and Assembly: filing, grinding, and polishing individual pieces so they fit together per engineering specifications. Testing and Maintenance: inspect finished tools for accuracy and repairing/adjusting active production tooling and dies. Use of Measuring Instruments: use and record measurements with micrometers, calipers, gauges, and scales to ensure fabrication requirements are met. Advise on the development of shop machines, tools, and processes for production of the SSI Energy Amplifier components. Training of junior machinist. QUALIFICATIONS Required Comprehensive knowledge of available tool and die equipment uses, maintenance, and repair. Ability to operate manual and CNC machining and grinding equipment. Proficiency in using precision measuring instruments. Experience working with a range of metals (i.e. not just SS or Al). Strong knowledge and understanding of reading engineering drawings, tolerances, and machining principles. Skill in techniques for tooling repair. Strong analytical and problem-solving skills to diagnose and resolve tooling issues. Working knowledge of geometry, trigonometry, and algebra for tool design and operation. 10 years of experience as a Machinist, Tool and Die Preferred Highschool Diploma or the equivalent BENEFITS We offer health, dental, and vision insurance. LOCATION & WORK POLICY This role is fully in person in Austin, Texas. Our facility is located next to Austin Airport. #J-18808-Ljbffr
