Location: Greater Noida, Gautam Buddha Nagar, Uttar Pradesh
Role Overview
We are looking for a skilled Hardware Design Engineer with strong hands-on experience in schematic design, PCB layout, and IoT-based product development. The candidate should be able to understand product specifications, convert them into practical electronic hardware designs, prepare schematics, design PCB layouts, and support the complete hardware development cycle from concept to production.
The most important requirement for this role is excellent PCB layout capability using Altium Designer. Experience in IoT, embedded, communication, metering, industrial, or battery-powered products will be highly valuable.
Key Responsibilities
· Understand product requirements and technical specifications given by the product or engineering team.
· Convert functional requirements into reliable electronic hardware designs.
· Select suitable components such as microcontrollers, communication modules, sensors, connectors, power devices, memory devices, and protection components.
· Prepare complete schematics for embedded and IoT-based products.
· Perform basic design calculations for power supply, current consumption, signal levels, protection circuits, and thermal considerations.
· Design hardware around communication interfaces such as UART, SPI, I2C, RS485, USB, Ethernet, CAN, LTE, NB-IoT, Wi-Fi, Bluetooth, and GNSS modules.
· Design power supply sections including AC-DC, DC-DC, LDO, battery backup, supercapacitor backup, and input protection circuits.
· Create production-ready PCB layouts using Altium Designer.
· Perform component placement, routing, grounding, power plane design, and controlled separation of noisy and sensitive sections.
· Design 2-layer, 4-layer, and preferably higher-layer PCBs as per product requirements.
· Follow strong PCB design practices for EMI/EMC reduction, signal integrity, power integrity, thermal management, creepage and clearance, isolation, ESD protection, surge protection, and field reliability.
· Design layouts for IoT products using GSM, LTE, NB-IoT, Wi-Fi, Bluetooth, GNSS, or other communication modules.
· Follow RF module layout guidelines including antenna placement, keep-out areas, RF trace routing, grounding, and manufacturer recommendations.
· Ensure correct decoupling capacitor placement, return paths, ground stitching, via strategy, and separation of analog, digital, power, and RF sections.
· Prepare PCB manufacturing and assembly outputs including Gerber files, drill files, pick-and-place files, BOM, assembly drawings, fabrication notes, and penalization inputs when required.
· Review PCB layouts for DFM, DFA, testability, manufacturability, and long-term reliability.
· Coordinate with PCB fabrication and assembly vendors to resolve production issues.
- IoT Product Design Experience
· Smart meters, industrial IoT devices, remote monitoring devices, data loggers, sensor devices, GPS/GNSS tracking devices, GSM/LTE/NB-IoT products, battery-operated IoT products, energy monitoring products, or automation products.
· Practical understanding of designing products that must work reliably in the field under noise, surge, temperature variation, and communication challenges.
Required Skills
· Strong knowledge of Altium Designer for schematic capture and PCB layout.
· Excellent PCB layout skills; this is the most critical requirement.
· Ability to read, understand, and design from specifications and datasheets.
· Good understanding of electronic components, circuit design, and practical hardware limitations.
· Experience with microcontroller-based embedded hardware design.
· Knowledge of communication interfaces such as UART, SPI, I2C, RS485, USB, Ethernet, CAN, and wireless module interfaces.
· Understanding of power supply design, input protection, reverse polarity protection, surge protection, and ESD protection.
· Knowledge of EMI/EMC design practices and grounding techniques.
· Ability to create BOMs, select alternate components, and support component sourcing.
· Basic debugging skills using multimeter, oscilloscope, logic analyzer, power analyzer, and soldering/rework tools.
· Understanding of PCB manufacturing, assembly, testing, and production release processes.
· Ability to work with firmware, mechanical, purchase, production, and testing teams.
· Good documentation skills for design notes, test reports, design calculations, and release files.
AI / Modern Tool Usage
AI usage is not mandatory, but the candidate should be open to using AI-assisted tools to improve design speed, research quality, documentation, and review accuracy.
· Component research and comparison.
· Datasheet review and design notes.
· Circuit design review and checklist preparation.
· BOM optimization and alternate part search.
· PCB design rule preparation and layout review checklists.
· Debugging support, test documentation, and technical research.
Preferred Skills
· Experience with RF module layout for LTE, NB-IoT, GSM, Wi-Fi, Bluetooth, or GNSS modules.
· Understanding of antenna placement, impedance control, RF ground clearance, and keep-out requirements.
· Experience with low-power and battery-operated designs.
· Experience designing products for mass manufacturing and field deployment.
· Knowledge of industrial standards related to EMI/EMC, surge, ESD, isolation, and safety.
· Experience with design validation testing, prototype bring-up, and field failure analysis.
· Knowledge of component lifecycle, alternate part selection, and cost optimization.
· Experience with smart energy meter hardware, metering products, or industrial communication products would be an advantage.
Qualification
· Diploma, B.Tech, or B.E. in Electronics, Electronics & Communication, Electrical Engineering, Instrumentation, or a related field.
· Equivalent practical experience in hardware and PCB design may also be considered.
Candidate Profile
· Strong in PCB layout and practical hardware design.
· Detail-oriented and careful with design rules, spacing, grounding, and manufacturability.
· Able to independently take a specification and convert it into a working hardware design.
· Comfortable working on IoT and embedded electronic products.
· Capable of designing for reliability, manufacturability, and field deployment.
· Good at hardware debugging and problem solving.
· Willing to learn and use AI tools to improve productivity.
