Senior Manufacturing Engineer

is building the power infrastructure that makes the AI era possible. As AI demand surges past what the grid and traditional data centers can support provides a new class of power technology proven at gigawatt scale and trusted by the worlds leading cloud and AI companies. Our systems are already deployed across 2.5 GW of hyper-scale campuses validated by top U.S. national labs and certified for grid-safe operation by major utilities. With real products in the field were scaling faster than the grid can transforming power from a bottleneck into a competitive advantage for the companies building the future.

The Role

The Manufacturing Engineer owns the design-to-line translation for integrated products turning BESS enclosures power conversion equipment and UPS/microgrid assemblies into repeatable scalable manufacturable builds. You will define assembly processes tooling work instructions and test checkpoints for products built both in-house and at contract manufacturers (CMs) and you will drive the continuous improvement of yield cycle time and cost.

This role sits at the intersection of electrical mechanical and controls disciplines. You should be comfortable moving between a battery modules electrical interfaces a switchgear/UPS cabinets power path and the mechanical fit-up of an integrated enclosure and equally comfortable on the shop floor solving a real build problem.

What Youll Do

• Develop and document manufacturing processes assembly sequences and standard work instructions for BESS enclosures DC subsystems power conversion systems (PCS) and medium-voltage UPS/microgrid assemblies.
• Lead Design for Manufacturing and Assembly (DFMA) reviews with product and design engineering to improve manufacturability reduce part count and drive down cost before designs are released.
• Define and validate station-level requirements: workstations tooling fixtures torque and crimp specs cabling and busbar routing and material flow across the line.
• Establish production readiness and manufacturing-readiness milestones for new products and product changes including in-process (IPQC) and end-of-line (EOL) test checkpoints.
• Specify and commission functional and safety test procedures insulation/dielectric (hipot) continuity BMS communication PCS/UPS functional test and integration with controls and telemetry.
• Partner with contract manufacturers on process transfer first-article inspection (FAI) production ramp and ongoing process control; travel to CM and field sites as needed.
• Drive root-cause analysis (8D 5-Why fishbone) on quality escapes and line stoppages and implement corrective/preventive actions.
• Lead continuous-improvement initiatives using Lean and Six Sigma methods (value-stream mapping kaizen SPC) to improve yield throughput and cost per unit.
• Own engineering change management (ECN/ECO) from the manufacturing side including bill-of-material (BOM) accuracy routings and configuration control in the ERP/PLM system.
• Support production capacity planning line balancing and takt-time analysis to meet build schedules.
• Champion a safety-first culture on the floor: LOTO arc-flash and high-voltage/medium-voltage safe work practices and ergonomic workstation design.
  
  

What Youll Bring

• Bachelors degree in Mechanical Electrical Manufacturing or Industrial Engineering (or equivalent experience).
• 3 years of manufacturing/process engineering experience with electromechanical products energy storage power electronics UPS switchgear electric vehicle or similar high-voltage/high-power hardware strongly preferred.
• Hands-on knowledge of assembly processes for electrical cabinets and enclosures: wiring/harnessing busbar and cable termination connectorization and panel build.
• Working understanding of power systems fundamentals DC battery systems PCS/inverters and AC power distribution/UPS and the safety practices that go with them.
• Proficiency with DFMA principles GD&T and reading electrical schematics and mechanical drawings.
• Experience creating work instructions process FMEAs control plans and test procedures.
• Familiarity with Lean Manufacturing and Six Sigma (Green Belt or higher a plus).
• Experience working in an ERP/PLM environment (e.g. SAP Oracle Arena Windchill) for BOMs routings and change control.
• Strong problem-solving skills disciplined documentation habits and the ability to work cross-functionally across engineering quality supply chain and operations.
• Willingness to travel (typically up to 25%) to contract manufacturers suppliers and project/field sites.

Nice to Have

• Experience with battery module/pack integration BMS interfaces and thermal management.
• Experience with medium-voltage equipment and microgrid or UPS integration.
• Knowledge of relevant standards: UL 9540 / UL 9540A UL 1741 IEC 62933 NFPA 70/70E and applicable UPS standards (e.g. UL 1778 / IEC 62040).
• Experience standing up a new production line or transferring a product to a contract manufacturer.
• Familiarity with test automation data acquisition (e.g. LabVIEW) and EOL test system development.
