R&D; Support

- Work closely with hardware design engineers during prototype development and bring-up.
- Assist in PCB assembly and testing of new designs.
- Support engineering teams in troubleshooting field-returned or failed boards.
- Provide practical feedback on PCB assembly, solderability, component placement, accessibility and reworkability.
- Maintain proper documentation of modifications and rework performed on prototype boards.

Lab, Inventory & Quality

- Maintain the lab inventory of components, consumables and tools; raise material requests and support BOM kitting with Stores.
- Keep the electronics lab organised and ESD-safe, and keep track of equipment calibration and maintenance.
- Follow quality procedures, using IPC workmanship standards as the reference for solder joint acceptance.

Required Qualifications & Experience

- Education: Diploma in Electronics, Electronics & Communication, Electrical or a related field.
- Experience: 1–3 years of hands-on experience in PCB assembly, soldering, electronics testing and hardware debugging preferred. Freshers with exceptional practical soldering and debugging skills may also be considered.
- Preferred Experience: Prototype PCBs and R&D; hardware; fine-pitch SMD soldering and PCB rework; component-level fault diagnosis; debugging power electronics and communication interfaces.
