Job Description

Our client needs a highly motivated and innovative Scientist to join

their New Product Development team.

The Scientist will drive the development of battery separator

technologies for lead-acid batteries, focusing on improving performance,

durability, and cost-effectiveness.

The Scientist will develop new formulations, optimize manufacturing

processes, and validate product performance from the lab to pilot-scale

production.

The Scientist focus area's Polyethylene (PE) separators, Absorbed Glass

Mat (AGM) materials, Silica-filled rubber separators, autoclaved

vulcanized rubber separators. Prefer Lead-acid systems Li-Ion a plus.

Responsibilities:

- Lead the design and synthesis of new, high-performance battery

separator materials (polyethylene, silica-filled materials, and AGM)

to meet emerging market needs.

- Optimize manufacturing processes including extrusion, pore

formation, and coating technologies to enhance separator

permeability, mechanical strength, and electrical resistance.

- Utilize Design of Experiments (DOE) to structure and execute

comprehensive testing protocols to evaluate separator-level

attributes (surface chemistry, wettability, pore structure) and

their impact on cell performance.

- Lead programs for incremental product and quality improvement using

tools; DOE, problem solving tools such as root cause analysis and

EVOP (evolutionary optimization)

- Collaborate with cell developers to integrate new separators into

prototype cells, conducting abusive, electrochemical, and life-cycle

tests to validate improvements. Evaluate separator performance

focusing on ER, acid displacement, dendrite suppression, and

oxidation stability.

- Utilize advanced analytical equipment (FIB-SEM, CT scanning, mercury

porosimetry) to analyze material microstructure and failure

mechanisms.

- Collaborate with cross-functional teams (Manufacturing, Sales,

Quality) to transfer new products from the laboratory into

pilot-scale and commercial production.

- Write detailed technical reports, SOPs, and conference materials

(presentations, technical papers, etc.), and present research

findings to stakeholders.

- Awareness of the patent landscape, ensure programs are safe to run

to product fruition, where R D lead to unique solutions, to file

patents where appropriate to protect MP innovation and IP.

- Lead by example to promote a zero-incident safety culture

- Ensure strict adherence to safety policies, procedures, and PPE

requirements

- Identify opportunities to improve processes, reduce waste, and

increase efficiency

- Encourage team-driven ideas and implement practical, data-driven

solutions

- Promote respect, inclusion, and engagement In a collaborative

environment

Qualifications:

Requirements:

- BS degree required, advanced degree preferred; Materials Science,

Chemical Engineering, Polymer Science, or related field.

- 5 + years in battery R D focused on polymers, porous membranes, or

separator technology.

- Polyethylene (PE) separators, Absorbed Glass Mat (AGM) materials,

Silica-filled rubber separators, autoclaved vulcanized rubber

separators.

- Strong understanding of polymer physics, surface chemistry, and

electrochemical transport mechanisms in porous materials.

- Hands-on capability with extrusion, polymer compounding, and coating

technologies.

- Expertise with material characterization tools: SEM, DSC, TGA,

Porosimetry, Tensile testers ICP.

- Familiarity with standard global battery testing methods (cycling,

EIS, CV), working to American, European and Asian systems as

necessary.

- Experience using AI-enhanced modeling and high-throughput data

analysis to accelerate component optimization is preferred.

- Strong problem-solving skills, ability to work independently in a

fast-paced environment.

- Proven ability to manage NPD projects, and excellent technical

communication skills.

- Travel domestically and Internationally to internal plants,

customers and conferences.
