Job description

AboutEnsurgeMicropower

EnsurgeMicropower (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.

This is a high-impact, hands-on role at the center of Ensurge’s transition from technology demonstration to product delivery.

You willbe 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
  

Key Responsibilities

Manufacturing Ownership & Output

• Own daily manufacturing performance for the Assembly, Laser, and Material Handling areas

Process to Production Conversion

• 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

Equipment & Line Readiness

• 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

Hardware & Automation (Strong Plus)

• Design or influence:
  • Fixtures
  • Handling systems
  • Assembly tooling

Material Flow & Manufacturing System Design

• 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

Quality, Control & Documentation

• 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

Problem Solving & Continuous Improvement

• 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.)

WhatWe’reLooking For

• 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

Preferred Qualifications

• 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

Personal Attributes

• Ownership mentality — sees problems through to resolution
• Execution-focused — prioritizes results over theory
• Systems thinker — understands interactions across process, equipment, and flow
• Low ego, high accountability — works across teams to get things done
• Comfortable in a fast-moving, scaling environment

Salary Range:

$161,626.00-$197,833.00

The base salary range is specific to California. The salary of the final candidate selected for this role will be determined by a variety of factors, including, but not limited to, internal equity, experience, education, specialty, and training.
