Job Title – Application Engineer Location – Leanwatts HQ, Hyderabad, India

At Leanwatts, we develop creative power electronic solutions for electric mobility and energy applications through continuous research, engineering, and manufacturing. Our 'Designed and Made in India' approach drives us to build reliable, high-performance products for the future of transportation and energy.
We are looking for an Application Engineer to help customers integrate and validate Leanwatts' EV chargers and power electronic products. This is a hands-on, customer-facing engineering role covering product selection, charger–battery integration, testing, troubleshooting, and production handover. You will work with hardware, firmware, quality, production, and sales teams to take customer applications from requirements to technical acceptance.
Capture battery chemistry, pack voltage, charging current, CAN requirements, connectors, installation constraints, and acceptance criteria. Product Selection & Configuration: Coordinate approved charging parameters, firmware versions, cable assemblies, and connector details with the responsible engineering teams.
● Coordinate sample readiness and configuration checks, support customer evaluation, and record test conditions and feedback. Testing & Validation: Plan and execute application tests for charging behaviour, output regulation, protection responses, and thermal performance. Reproduce customer issues, analyse test data, and distinguish configuration, communication, hardware, and firmware causes. Prepare application notes, customer-specific datasheets, test reports, configuration records, and integration guidance. Transfer approved application requirements, firmware and hardware versions, test criteria,



and variant details to production and quality. Feed recurring field issues and application needs into product improvements.
Education & Required Experience

- Education: B.E. or B.Tech in Electronics, Electrical Engineering, or a related discipline; equivalent relevant practical experience may also be considered.
- Experience: Hands-on experience in application engineering, product testing, integration, or technical support for electrical or electronic products, with the ability to work systematically through technical problems.
- Relevant Work: Ability to explain a practical integration or troubleshooting project, including the requirements, measurements, root cause, corrective action, and verification.

Electrical Fundamentals: Ability to assess charger and battery compatibility, connector pinouts, cable requirements, and operating limits. Recognise electrical and thermal risks and escalate unsafe or unclear conditions.
Select suitable instruments and follow approved electrical safety procedures.
● Ability to interpret CAN specifications and logs, check message IDs, scaling, timing, and basic bus configuration, and troubleshoot charger–BMS communication with firmware engineers.
Track multiple customer applications, prioritise open issues, and communicate risks. Maintain approved configuration and revision records and obtain sign-off before changes reach customers or production.
Direct experience with EV chargers, battery packs, BMS integration, automotive electronics, or power converters. Data Analysis & Improvement: Familiarity with test-data analysis, basic scripting or test automation, and structured root-cause methods. Experience turning field feedback into validated product or process improvements is an advantage.
