Description :

Client is seeking a highly motivated Battery Engineer with expertise in solid-state battery development to join a fast-paced, innovative, and collaborative team driving the next generation of microbattery energy storage technologies.

Support second generation battery technology using Client's ceramic processing expertise to double energy density for IoT and wearable devices.

The ideal candidate will bring hands-on laboratory experience with solid electrolytes, cathode integration, and cell testing / analysis. The role involves material optimization, cell prototyping, and process development to advance next-generation energy storage technologies.

Key Responsibilities

Develop and optimize solid-state cell architectures, focusing on cathode optimization and solid electrolyte interfaces.

Experienced in anode free cell configurations including deposition, interface engineering, and evaluating stability against solid electrolytes.

Integrate cathode materials with solid electrolytes to improve performance, cycle life, and reliability.

Hands-on cell fabrication and prototyping, including electrolyte deposition, cathode integration, and full-cell assembly.

Perform hands-on cell-level testing (cycling, impedance, rate capability, DC polarization) and translate data into meaningful failure mechanisms

Characterize electrochemical performance (EIS, CV, cycling) and correlate results to material and interface properties.

Troubleshoot cell failures through structured root cause analysis and propose engineering solutions.

Support thin-film deposition, coating, and integration processes for electrolyte and electrode layers. Collaborate with cross-functional teams on design, fabrication, and scale-up of solid-state battery prototypes.

Core Expertise :

Electrochemistry and battery systems knowledge, and Thin film deposition processes (e.g., RF magnetron sputtering, metal evaporation).

Hands-on Requirement :

At least 3 years of practical engineering experience beyond academic research not purely R&D.

Additional Skills :

Familiarity with encapsulation of thin film materials and process design experiments (DOE).

Flexibility in Background :

Candidates with experience in related electrochemical fields (e.g., fuel cells) are acceptable if they meet thin film expertise.

Soft Skills :

Strong communication and ability to hit the ground running are critical differentiators during selection.

Required qualifications :

PhD or MS in Materials Science, Electrochemistry, Chemical Engineering, or related field with 3 years of experience in the fields of electrochemistry, battery development, cell design or other related experiences. Manager will consider additional years experience in lieu of the higher level education.

Hands-on experience with solid electrolytes such as LiPON, sulfides, garnets, or polymer-based systems.

Knowledge of thin-film deposition techniques (sputtering, ALD, evaporation) and cathode / electrolyte integration.

Strong background in hands-on electrochemical testing and failure analysis (EIS, impedance growth modeling, capacity fade diagnostics).

Experience with hands-on cell design, fabrication, and scaling for solid-state battery prototypes.

Interview process : 1st round interview via Teams with Client manager and a Client engineer; 2nd round interview with Ensurge team members (onsite if local otherwise Teams). Ensurge provides feedback but Client makes the final decision.
