About The Position

About Ensurge Micropower Ensurge Micropower (OSE: ENSU) is a pioneer in solid-state microbattery technology, enabling the next generation of intelligent, connected devices. Leveraging proprietary thin-film and roll-to-roll manufacturing, Ensurge delivers safe, high-energy-density batteries for wearables, health tech, industrial sensing, and defense applications. As our technology transitions from development to production, disciplined manufacturing execution becomes the differentiator. Role Overview: Ensurge is seeking a Senior Manufacturing Engineer (IC) to own and scale the Assembly, Laser, and Material Handling processes from pilot through early production. This role is not just about process — it is about delivering manufacturing results. You will be responsible for: Turning engineering processes into production-capable systems Driving output, yield, and stability on the line Building the infrastructure (process, equipment, flow, documentation) required for repeatable execution This is a high-impact, hands-on role at the center of Ensurge’s transition from technology demonstration to product delivery.

Requirements

  • 7–12+ years in manufacturing engineering (battery, semiconductor, thin-film, or similar)
  • Proven experience owning manufacturing processes on the floor
  • Strong track record of: Driving yield and throughput improvements Supporting or leading pilot → production scale-up
  • Hands-on mindset — comfortable working directly with: Equipment Technicians Operators

Nice To Haves

  • Experience with: Laser processing or micromachining Precision assembly or micro-scale systems Automated material handling
  • Background in thin-film, semiconductor, or battery manufacturing
  • Experience with MES, traceability systems, or data-driven manufacturing

Responsibilities

  • Own daily manufacturing performance for the Assembly, Laser, and Material Handling areas
  • Drive output, yield, uptime, and cycle time
  • Support production directly — troubleshooting issues in real time
  • Partner with Operations to ensure line execution meets plan
  • Convert R&D processes into repeatable, production-ready workflows
  • Define and lock: Process flows Critical parameters (CPPs) Control limits and OCAPs
  • Ensure processes are robust, stable, and scalable
  • Work with Equipment Engineering to: Define tool requirements Improve reliability and uptime Implement process-driven upgrades
  • Lead tool qualification and process acceptance
  • Ensure equipment supports throughput, precision, and repeatability
  • Design or influence: Fixtures Handling systems Assembly tooling
  • Own flow from sheet → quad → final assembly
  • Reduce bottlenecks, WIP, and inefficiencies
  • Improve line balance and production scheduling alignment
  • Support layout and flow improvements as the system scales
  • Partner with Quality to implement: SPC and process control Traceability and data capture
  • Build and maintain: SOPs Process specs Control plans
  • Ensure manufacturing is data-driven and auditable
  • Lead structured RCA on: Yield loss Defects Downtime
  • Implement sustainable fixes — not workarounds
  • Drive continuous improvement aligned to operational excellence principles (standard work, DMS, etc.)
