About the role
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 Thin-Film
Engineering processes — deposition (PVD/Sputtering, PECVD, ALD) and etch (RIE) — from
pilot through early production. This role is not just about process — it is about delivering
manufacturing results.
Responsibilities
- Own daily manufacturing performance for the PVD/Sputtering, PECVD, ALD, and RIE process 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 critical process parameters (CPPs) — e.g., chamber pressure, Ar/process
gas flow, RF/DC power, substrate bias, deposition rate, film stress and thickness
uniformity targets (PVD/PECVD); precursor/co-reactant pulse and purge times, cycle
count, growth per cycle (GPC), and substrate temperature (ALD); RF power, gas
chemistry (e.g., CF4/O2/Cl2), etch rate, selectivity, sidewall profile/anisotropy, DC bias,
and endpoint detection (RIE)
Define and lock control limits and OCAPs
Ensure processes are robust, stable, and scalable
Work with Equipment Engineering to:
Define tool requirements (sputter cathodes/targets, PECVD chambers, ALD reactors and
precursor delivery systems, RIE/ICP-RIE chambers and endpoint detection systems,
RF/DC power supplies, vacuum, gas delivery, and abatement/scrubber systems)
Improve reliability and uptime
Implement process-driven upgrades
Lead tool qualification and process acceptance
Ensure equipment supports throughput, precision, and repeatability
Own flow from substrate input → deposition/etch → downstream handoff to 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 on film thickness, stress, uniformity, and conformality
- Film characterization (ellipsometry, profilometry, XRD, SEM/AFM, four-point probe) to validate deposition results against CPPs
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
- Use characterization data (SEM, XRD, cross-section imaging) to root-cause excursions
- Implement sustainable fixes — not workarounds
- Drive continuous improvement aligned to operational excellence principles (standard work, DMS, etc.) Qualifications Required
7–12+ years in manufacturing engineering with thin-film deposition and etch
(PVD/sputtering, PECVD, ALD, and/or RIE) in battery, semiconductor, or thin-film
industries
Proven experience owning manufacturing processes on the floor
Strong track record of driving yield and throughput improvements
Experience supporting or leading pilot → production scale-up
Hands-on mindset — comfortable working directly with equipment, technicians, and operators
Working knowledge of thin-film characterization techniques (e.g., ellipsometry,
profilometry, XRD, SEM) and their use in validating and controlling deposition processes
Preferred
Understanding of film stress engineering, plasma physics, RF coupling, and DC self-bias
Understanding of plasma etch chemistry, selectivity, anisotropy, and endpoint detection (RIE/ICP-RIE)
Familiarity with ALD precursor chemistry, self-limiting surface reactions, and pulse/purge sequencing
Vacuum systems and chamber conditioning experience
Experience with image-based film/defect characterization (SEM, optical microscopy) and
correlating characterization data back to process control limits
Experience with MES, traceability systems, or data-driven manufacturing
Salary Range:
$162,000-$198,000
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.
