Antora Energy is a climate tech company developing thermal battery systems that convert low-cost electricity into reliable heat and power for industry, data centers, and the grid. The company is scaling production and preparing a new generation of products alongside a new gigafactory. In this role, you will own the design and engineering of production tooling, equipment, and processes from concept through deployment. You will personally design fixtures, workcells, and safety-critical lifting and handling equipment using first-principles structural analysis, hand calculations, and FEA. Your designs will directly set production rates, enable new product launches, and shape the next-generation build process. Key responsibilities include: **Design & Process Development** - Lead process, tooling, and workcell design for assigned subsystems, carrying designs from requirements and concept through structural analysis, detailed design, release, fabrication, and proof load testing - Partner with design engineering to define the build sequence from product concept - Review product designs early and drive manufacturability into them before designs harden - Develop work instructions and PFMEAs **Factory Launch Support** - Translate production processes into facility requirements: layout, material flow, workstation footprints, and tooling/equipment needs - Partner with factory planning and capital equipment owners through launch **Production Ownership & Continuous Improvement** - Own your stations through production support as products evolve - Develop and integrate production test processes and rigs while maintaining takt, line balance, and rework access - Participate in EVT builds, process plan releases, change incorporation, issue triage, tooling upkeep, and equipment commissioning - Improve safety through partnership with production and EH&S teams **Culture & Collaboration** - Contribute to a team-first, mission-driven culture - Invite critique early and treat feedback as material that strengthens work - Be a collaborative partner for technicians and engineers **Requirements** - Bachelor's degree in Mechanical or Aerospace Engineering, or equivalent practical experience - 7+ years in manufacturing, NPI, or equipment design engineering, including personally designing tooling and equipment for production environments (exceptional candidates with 5+ years and a deep design record will be considered) - Proven ability to take products from concept to build sequence to running process, with designs carried through detailed design, GD&T, and formal change control - First-principles structural design capability: FEA verified by hand calculations, with sound judgment on loads, load paths, and factors of safety, especially for safety-critical lifting and handling equipment - Proficiency in 3D CAD (SolidWorks preferred) and hands-on fluency with machining, welding, and sheet metal design - Grounded in DFM, lean manufacturing principles, PFMEA, and work instruction development - Strong cross-functional collaboration skills, decisive with incomplete information, comfortable in fast-moving startup environments - Ability to travel domestically as needed, up to approximately 25% during factory launch periods **Desired Qualifications** - Experience designing ground support equipment, heavy handling fixtures, test systems, or custom production machines - Experience with welding process development or qualification - Experience specifying, integrating, or commissioning automated production equipment and custom machinery - Experience launching a new factory or production line from the ground up - Experience developing production test systems and validation methods - Experience with MES/PLM systems, BOM structuring, and formal change management - Experience with battery, energy storage, or other thermally or electrically demanding hardware products
