Description
About Bessium: Bessium Energy and Solutions is a pioneering energy storage company dedicated to designing and assembling advanced lithium-ion battery modules for applications in BESS (Battery Energy Storage Systems), Telecom, EV, UPS, and hybrid power systems. We are committed to innovation, reliability, and sustainability through cutting-edge technology made in India. Role Overview: We are looking for a passionate Design Engineer with experience in mechanical and/or electrical design of lithium-ion battery packs and modules. You will be responsible for translating technical requirements into robust, manufacturable designs and play a key role in developing safe, high-performance energy storage products. Key Responsibilities: Design mechanical enclosures, module casings, busbars, and harness layouts for lithium-ion battery packs. Create 2D/3D CAD models and detailed drawings using tools like SolidWorks, AutoCAD, or similar software. Collaborate with R&D and production teams to ensure design-for-manufacturability (DFM) and ease of assembly. Develop wiring diagrams, cell arrangements, and structural layouts ensuring thermal and electrical safety. Integrate design inputs from BMS, cooling systems, safety standards, and certification requirements (UN38.3, AIS, IEC). Conduct tolerance analysis, material selection, and thermal/structural validation in coordination with simulation team. Support prototyping, validation testing, and iterate designs based on test feedback and production learnings. Maintain BOMs and coordinate with supply chain for component specifications and vendor interactions. Qualifications: Education: B.E./B.Tech in Mechanical, Electrical, or Mechatronics Engineering. Postgraduate degree is a plus. Experience: 2–4 years of experience in lithium-ion battery design or closely related electro-mechanical systems. Technical Skills: Proficiency in CAD tools (SolidWorks, Creo, AutoCAD, etc.). Understanding of battery module design, cell layout strategies (LFP), thermal management, and safety compliance. Familiarity with GD&T, FEA basics, and sheet metal/plastic part design. Soft Skills: Detail-oriented with strong problem-solving skills. Ability to coordinate with cross-functional teams and meet tight project timelines. Good documentation and communication skills. Preferred: Experience working with LFP cell suppliers (BYD, CATL, EVE, etc.). Exposure to design validation through FEA/thermal simulation tools. Understanding of electrical schematics, PCB layouts, and BMS integration (for hybrid roles). Why Bessium? Build innovative products that power the energy transition. Be part of a young, dynamic team driving India’s battery revolution. Opportunity to work across multiple domains (EV, grid storage, hybrid systems). Growth, ownership, and learning in a fast-paced environment. To Apply: Send your resume and portfolio (designs) to reachus@bessium.com with subject: Application – Design Engineer Show more Show less
