Job Summary
We are looking for a skilled Hardware Engineer to design, develop, test, and validate electronic hardware for embedded, industrial, IoT, railway, and monitoring systems. The candidate will be responsible for schematic design, PCB development, component selection, prototype testing, troubleshooting, and production support.
Key Responsibilities
- Design analog, digital, and microcontroller-based electronic circuits.
- Prepare circuit schematics, PCB layouts, BOM, and technical documents.
- Select suitable MCU, memory, sensors, communication ICs, power supplies, and protection components.
- Develop interfaces for RS232, RS485, CAN, UART, SPI, I2C, Ethernet, GSM, GPS, and RF modules.
- Design isolated signal-conditioning circuits for voltage, current, PT, CT, and sensor inputs.
- Design power-supply circuits, including DC-DC converters, regulators, filtering, reverse-polarity protection, surge protection, and EMI protection.
- Develop relay outputs, digital inputs, analog inputs, display interfaces, keypad interfaces, and stepper-motor control circuits.
- Perform PCB bring-up, hardware debugging, testing, and fault analysis.
- Use oscilloscopes, multimeters, logic analyzers, power supplies, function generators, and other laboratory equipment.
- Coordinate with firmware, software, mechanical, and testing teams.
- Support prototype assembly, calibration, environmental testing, and field trials.
- Resolve component obsolescence and suggest suitable alternatives.
- Support production teams during PCB assembly and product manufacturing.
- Prepare test procedures, design documents, compliance reports, and technical specifications.
- Ensure the design meets reliability, safety, EMI/EMC, temperature, vibration, and industrial standards.
Required Technical Skills
- Strong knowledge of analog and digital electronics.
- Experience in schematic design and multilayer PCB design.
- Knowledge of microcontrollers such as STM32, NXP, Renesas, Nordic, PIC, AVR, or similar.
- Experience with Altium Designer, OrCAD, KiCad, Eagle, or equivalent PCB-design tools.
- Good understanding of RS485, RS232, CAN, UART, SPI, and I2C communication.
- Knowledge of sensors, ADC, DAC, op-amps, signal conditioning, isolation, relays, and protection circuits.
- Understanding of power-supply design and grounding techniques.
- Knowledge of EMI/EMC, surge, ESD, filtering, and electrical-isolation requirements.
- Ability to read datasheets, circuit diagrams, and technical specifications.
- Experience in hardware testing, debugging, and root-cause analysis.
- Basic understanding of embedded C and firmware interaction will be preferred.
Preferred Experience
- Experience in railway, automotive, industrial automation, IoT, energy monitoring, or embedded products.
- Experience with speed sensors, PT/CT inputs, current and voltage measurement circuits.
- Experience in designing hardware for harsh environments.
- Knowledge of temperature, vibration, shock, humidity, and endurance testing.
- Experience with LED displays, LCDs, stepper motors, data loggers, and monitoring systems.
- Familiarity with RDSO, IEC, EN, AIS, or industrial standards will be an advantage.
