Role Overview: Job Description

As a Trainee Battery Pack Development Engineer, you will assist the R&D; team in the design,

assembly, testing, and validation of LiFePO4/ LTO battery storage systems for electric marine

applications. You will gain hands-on exposure to cell characterization, pack integration,

electrical testing, and safety protocols under the mentorship of senior battery engineers.

Key Responsibilities

● Pack Assembly & Integration Support: Assist in the mechanical and electrical assembly of

prototype lithium battery packs (cell staging, busbar connections, wiring harnesses, and

insulation).

● Testing & Characterization: Conduct cell- and pack-level charging/discharging tests,

capacity measurements, cycle-life evaluation, and temperature logging in accordance

with standard operating procedures.

● BMS Integration Support: Assist with wiring, sensor placement (thermistors, voltage sense leads), and basic configuration testing of Battery Management Systems on

assembled packs.

● Quality & Safety Compliance: Follow strict high-voltage and workshop safety standards
