Senior Manager, Assembly Operations

Hyliion is committed to creating innovative solutions that enable clean, flexible and affordable electricity production. The Company’s primary focus is to develop distributed power generators that can operate on various fuel sources to future-proof against an ever-changing energy economy. Job Purpose The Senior Manager, Assembly Operations is responsible for Core, Module, and Harness Assembly at the Cedar Park, Texas facility as KARNO production moves from development builds to repeatable production. Hyliion designs and builds the KARNO Power Module, a fuel-agnostic linear generator for data center, commercial and industrial, and defense applications, combining additive manufacturing with precision electromechanical assembly. The position runs the shop floor through Safety, Quality, Delivery, Cost, and People (SQDCP) performance, builds the standard work and discipline that make production predictable, and develops supervisors into front-line leaders. Designs are maturing, work instructions are evolving, and some assemblies are still being productionized, so the position brings structure to that environment without slowing the build. Continuous improvement is part of the daily work of the role. Leadership is exercised on the production floor by listening to the people doing the work and solving problems alongside them, with high standards and accountability delivered with respect. AI at Hyliion At Hyliion, AI is core to how we work. We equip every team member with leading AI tools and count on you to use them — to move faster, solve harder problems, and help us realize the full potential of KARNO technology for the world. Duties and Responsibilities • Own Safety, Quality, Delivery, Cost, and People (SQDCP) performance across Core, Module, and Harness Assembly, with defined metrics, visual management, and daily tiered accountability. • Build a safety-first culture in an environment that includes high-voltage systems, pressurized assemblies, and heavy lifting and rigging, and lead incident investigations and corrective actions through closure. • Partner with Quality to improve first-pass yield, contain escapes, and drive structured root cause and corrective action (8D, A3) on build issues. • Deliver to the build plan by translating production schedules into staffing, shift, and capacity plans and managing schedule adherence day to day. • Control labor efficiency, scrap, rework, and consumables, and support operating budget development for the assembly organization. • Take ownership of assembly processes in transition from development to production, identifying gaps in work instructions, tooling, fixtures, and in-process test and closing them in partnership with Manufacturing Engineering and Quality. • Establish takt, line balance, and flow as volumes ramp, and use capacity modeling to anticipate constraints before they reach the floor. • Lead production readiness for new builds and process transfers into Cedar Park, including layout optimization, material presentation, technician training, and build validation. • Implement practical standard work that evolves with the design rather than waiting for a frozen process. • Lead continuous improvement from the gemba, running kaizen events and driving daily problem-solving at the point of work. • Apply lean tools with measurable results, including value stream mapping, value-added and non-value-added analysis, 5S, standard work, error-proofing, and flow design. • Deploy and mature site production system practices on the assembly floor. • Engage technicians in identifying and solving problems, and recognize the people who make improvements stick. • Lead, coach, and develop the Supervisor, Module & Harness Assembly and the Supervisor, Core Assembly, building front-line lea
