About Us: For over seven decades, Diamond Lighting has been illuminating spaces across the nation. We have stood the test of time by continuously evolving: transitioning from manufacturing traditional chokes and starters for tube lights, to pioneering high-efficiency LED systems, and now engineering cutting-edge, smart-home compatible lighting ecosystems.As we scale our operations and transition toward developing proprietary product lines, we are seeking a hands-on Electronics Engineer to lead our bench diagnostics, component repair, quality control, and new product development.

Key Responsibilities

1. Research, Development & Recent Technologies

● Technology Evaluation: Research and evaluate emerging smart lighting protocols (e.g., Matter over Thread, Zigbee 3.0, DALI-2, 0-10V, Phase Dimming) and smart control modules.

● Prototyping & IP Development: Assist in testing, prototyping, and developing proprietary lighting fixtures, housing designs, custom PCB layouts, and driver integrations.

● Competitor Teardowns & Benchmarking: Perform reverse-engineering teardowns on OEM/competitor products to evaluate heatsink performance, optical efficiency, driver topologies, and build quality.

2. Component-Level Bench Repair & Diagnostics

● Perform deep technical diagnostics and bench repairs on returned, damaged, or defective fixtures, LED boards, and electronic power supplies (drivers).

● Execute precision soldering, desoldering, component replacements, thermal compound re-application, and wire harness repairs.

● Maintain a detailed Failure Analysis Log to identify defect trends across product lines and factory batches.

3. Quality Control (QC) & Inbound Batch Testing

● Establish and execute QC inspection protocols for inbound shipments from overseas manufacturing partners.

● Test driver power factor,



voltage stability, thermal dissipation, color consistency, and flicker rates using lab testing equipment.

● Isolate defective factory batches prior to inventory distribution to retail showrooms and e-commerce fulfillment.

4. Technical Documentation & Lab Management

● Draft accurate wiring diagrams, installation manuals, and technical specification sheets for commercial contractors and installers.

● Maintain the internal hardware laboratory, keeping diagnostic tools (multimeters, oscilloscopes, soldering stations, bench power supplies) calibrated and organized.

Required Qualifications & Technical Skills

● Education: B.E. / B.Tech in Electrical Engineering, Electronics & Communication (ECE), or Mechatronics (Mandatory).

● Circuit Diagnostics: Proven hands-on experience in AC/DC power electronics, PCB troubleshooting, and component testing.

● Soldering & Lab Skills: Proficiency in fine-pitch soldering, wire stripping, multimeter usage, and reading circuit schematics.

● Lighting & Smart Protocols: Familiarity with LED driver architectures, constant current vs. constant voltage systems, and wireless smart home protocols (Zigbee, Bluetooth Mesh, Thread) is a strong advantage.

● Problem-Solving Mindset: A methodical, analytical approach to root-cause analysis and hardware engineering.

What We Offer

● Fixed monthly salary tailored to technical capabilities and qualifications (INR 17,500-25,000) + performance-based bonuses.

● Dedicated working space.

● Direct involvement in bringing original, proprietary hardware products from concept to market.

● Clear career path toward Lead Product Engineer or Head of Hardware R&D.;
