Job Description
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.
Key Responsibilities
Manufacturing Ownership & Output
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
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
- Handling systems
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.)
What We’re Looking 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.
