You will lead the design of liquid-cooled, air-cooled, and hybrid thermal systems supporting multi-MW/MWh BESS installations operating in data centers. This role requires deep, hands-on expertise in inverter system design, thermal cooling, advanced simulation, and BESS safety compliance. You will lead a team of hardware, firmware, and mechanical engineers across thermal, site controls, sensor/safety, and manufacturing functions to ensure the product meets performance, reliability, manufacturability, serviceability, compliance, and cost targets - delivering production-ready designs from concept through deployment while optimizing CAPEX and long-term OPEX. What you will do * Develop in-house or outsourced thermal cooling solutions (liquid cooling, heat exchangers) across the full product lifecycle. * Work in cross-functional teams of inverter hardware, firmware, test automation, and mechanical engineers, including teams spread across geographies such as Bangalore, India. * Specify, design, verify, and debug complex site controls connecting to the BMS (battery management system) and EMS (energy management system). * Integrate grid-scale inverter PCS with MWh-scale DC BESS for data centers. * Participate in early-stage product development, communicate expectations, and ensure successful capture of design, manufacturing, supply chain, quality, test, and service requirements. * Develop schedules for new product development from concept to launch - setting milestones, assessing and mitigating risks, building action plans, coordinating activities, and driving results across cross-functional teams. * Conduct regular project status meetings with the project team and stakeholders to communicate and coordinate activities. * Deliver new products on time, within budget, and at the expected quality and reliability levels. * Serve as the central technical leader across mechanical, electrical, and firmware engineering, cloud/mobile software, quality, manufacturing, and supply chain/operations. * Guide daily engineering tasks, including schedule prioritization and tracking the status and resolution of bugs/issues. * Facilitate initial build plans, drive material readiness with supply chain, and evaluate constraints. * Collaborate with engineering teams to solve technical problems and provide rapid prototyping support. * Collaborate with manufacturing and quality teams to develop efficient methods for assembling and testing products. * Generate high-value ideas and transform them into platform-level designs. * Support system architecture, cost-reduction proposals, and failure root-cause analysis. * Engage with internal technical communities and contribute to cross-team knowledge sharing. * Mentor and grow engineers on the team. * Lead efforts to meet grid code requirements and certifications (UL and IEC) for BESS applications serving data centers. * Define engineering requirements, develop test plans, and deliver proofs of concept (POCs). * Champion technical excellence, rigorous documentation, and scientific discipline. * Serve as a subject matter expert for next-generation platforms., * High-voltage DC and AC power distribution units (PDUs). * High-density liquid cooling thermal design for high-volume manufacturing. * Field quality improvement and cost reduction through Value Analysis/Value Engineering (VAVE). * Experience designing cabinet and containerized solutions. * Site EMS experience with inverter and BMS controls. ## Related Videos - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [Flex your Energy: Building a Cloud-Native Platform for Renewable Energy Communities](https://www.wearedevelopers.com/videos/1990-flex-your-energy-building-a-cloud-native-platform-for-renewable-energy-communities) - [The Sustainability Race: AI's Promises, Pitfalls and Potential](https://www.wearedevelopers.com/videos/100155-the-sustainability-race-ai-s-promises-pitfalls-and-potential) - [Playing Pong on a shoulder press machine](https://www.wearedevelopers.com/videos/100140-playing-pong-on-a-shoulder-press-machine) - [Breaking the Hardware Mindset: Overcoming Barriers to System-Level Innovation](https://www.wearedevelopers.com/videos/1635-breaking-the-hardware-mindset-overcoming-barriers-to-system-level-innovation) - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) ## Related Articles - [A Guide to Green Tech and Green IT Careers](https://www.wearedevelopers.com/magazine/374-a-guide-to-green-tech-and-green-it-careers) - [Now is the time for industrialized software development](https://www.wearedevelopers.com/magazine/601-now-is-the-time-for-industrialized-software-development) - [Data Science & more: The Lopez dilemma](https://www.wearedevelopers.com/magazine/10-data-science-more-the-lopez-dilemma) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Everything a Developer Needs to Know About MCP with Neo4j](https://www.wearedevelopers.com/magazine/604-everything-a-developer-needs-to-know-about-mcp-with-neo4j) - [What Makes WeAreDevelopers World Congress Different From Every Other Tech Event?](https://www.wearedevelopers.com/magazine/701-what-makes-wearedevelopers-world-congress-different-from-every-other-tech-event)
