Role Overview

Ensurge is seeking a Head of Manufacturing Engineering to lead the industrialization and transfer of breakthrough solid-state battery technology into scalable manufacturing.

This role is the critical interface between Technology and Manufacturing - responsible for ensuring that processes developed in R&D are designed for manufacturability, robustness, yield, and scale as products progress through key roadmap milestones (POC → EVT → DVT → Pilot → Volume). Reporting to the COO, this leader will own process definition, equipment readiness, documentation, and manufacturing handoff, enabling Ensurge to transition from innovation-driven development to repeatable, high-confidence execution.

This is a builder role - hands-on, highly cross-functional, and central to Ensurge's ability to commercialize with confidence. As Ensurge's products mature, disciplined manufacturing execution becomes the differentiator.

Key Responsibilities

Technology → Manufacturing Process Transfer

• Own the end-to-end process transfer from Technology/R&D into Manufacturing
• Define clear phase-gate criteria for readiness at each product and process milestone
• Translate experimental processes into manufacturable, repeatable, and controlled flows
• Ensure Design for Manufacturability (DFM) and Design for Scale principles are embedded early

Process Engineering & Industrialization

• Establish and maintain best-known methods, critical process parameters (CPPs), and control plans
• Lead process characterization, capability development (Cp/Cpk), and yield ramp
• Drive standardization across 75 µm and 10 µm platforms while enabling future variants
• Partner with Quality to embed process control, SPC, and change management discipline

Equipment & Manufacturing Readiness

• Partner with Equipment Engineering to define process-driven equipment requirements
• Lead equipment qualification, process acceptance, and handoff to operations
• Define process windows, tool-to-tool matching strategies, and uptime requirements
• Ensure equipment design supports throughput, reliability, and maintainability

Cross-Functional Leadership & Alignment

• Act as the primary integration point between Technology, Manufacturing, Quality, and Operations
• Resolve ownership gaps between "who develops" and "who runs" the process
• Enable Manufacturing teams with clear documentation, training, and escalation paths
• Support Operations in the daily execution once processes are released

Scaling Strategy & Roadmap Execution

• Build the manufacturing engineering roadmap aligned to Ensurge's product and customer milestones
• Support pilot line scale-up, sampling, and customer shipments with disciplined execution
• Identify process risks early and drive mitigation plans before they impact delivery
• Provide leadership-level visibility into readiness, gaps, and trade-offs

Team Leadership & Capability Building

• Build and lead a high-performing Manufacturing Engineering team
• Define roles, ownership, and interfaces across process, equipment, and quality engineering
• Establish a culture of rigor, learning, and accountability
• Mentor engineers to think beyond experimentation toward industrial systems
