Key Responsibilities

• Lead the design and development of electrical and electronic systems for HVAC machines, including screw chillers and thermal products.
• Prepare, review, and approve electrical schematics, wiring diagrams, control panel layouts, interlock logic, and BOMs.
• Select and integrate electrical and electronic components such as VFDs, controllers, PLCs, HMIs, sensors, protection devices, and safety components.
• Lead and support PLC and HMI programming activities, including control logic review, I/O allocation, tag mapping, alarm handling, and parameter optimization.
• Drive BMS integration (BACnet / Modbus or equivalent), including points list definition, signal mapping, validation, and coordination with site/BMS teams.
• Support control philosophy development and close integration of electrical systems with controls and embedded software.
• Drive design validation testing (DVT), dry testing, performance testing, and troubleshooting in lab and factory environments.
• Lead root cause analysis and corrective action implementation for electrical and controls-related issues identified during testing or field operation.
• Support commissioning, field issues, and service escalations related to electrical, controls, and automation systems.
• Coordinate with Mechanical, Software, Product Management, QA, Sourcing, and Service teams to ensure successful product execution.
• Ensure compliance with applicable electrical standards, safety norms, cybersecurity guidelines (where applicable), and regulatory requirements.
• Support component localization, alternate sourcing, and cost optimization initiatives without compromising performance or reliability.
• Provide technical guidance, reviews, and mentoring to junior engineers and team members.

Required Skills & Qualifications

• Bachelor’s degree in Electrical, Electronics, or Instrumentation Engineering (or equivalent).
• 4 to 6 years of relevant industry experience, preferably in HVAC, industrial machinery, or automation systems.
• Strong machine-level experience with HVAC systems, particularly screw chiller machines and thermal products.
• Deep knowledge of industrial electrical systems, power distribution, control panels, safety circuits, and VFD applications.
• Solid working experience with PLC and HMI programming in industrial or HVAC applications.
• Proven exposure to BMS integration using standard industrial protocols such as BACnet and Modbus.
• Working knowledge of programming languages such as C, C++, Structured Text (ST), and Function Block Diagram (FBD); ability to review logic and coordinate with software teams.
• Hands-on experience in testing, commissioning, and troubleshooting complex HVAC and automation systems.
• Proficient in reading and interpreting electrical drawings, control schematics, functional descriptions, and technical specifications.
• Strong analytical, problem-solving, communication, and team-leadership skills.
