Location: Indore / Ahmedabad / Jaipur
Employment Type: Full time
Industry: Railway Technology and Industrial IoT
Role SummaryWe are hiring a hands-on Senior IoT Hardware & Embedded Systems Engineer to independently design, develop, test and deploy rugged embedded devices for railway and industrial applications.
The candidate must have practical experience in PCB design, embedded firmware, sensor integration, wireless communication, power electronics and field debugging. This is an execution-focused role requiring direct involvement from circuit design through field deployment.
Key ResponsibilitiesHardware and PCB Design• Independently design embedded hardware and production-ready PCBs.
• Prepare system architecture, schematics, PCB layouts, wiring diagrams and BOMs.
• Design microcontroller-based boards using ESP32, STM32 or equivalent platforms.
• Develop analogue, digital, mixed-signal, sensor-interface and power-supply circuits.
• Integrate GSM/4G, GPS/GNSS, LoRa, RF, Wi-Fi and BLE modules.
• Design signal-conditioning, filtering,



isolation and protection circuits.
• Design DC-DC power supplies, battery-charging circuits and battery-management interfaces.
• Apply correct grounding, decoupling, noise reduction, RF-layout and EMI/EMC practices.
• Generate Gerber, drill, BOM, pick-and-place and assembly files.
• Coordinate PCB fabrication and assembly, followed by board bring-up and debugging.
• Modify designs based on testing, production and field feedback.

Embedded Firmware• Develop embedded firmware using C/C++.
• Interface sensors, communication modules, relays, switches and industrial inputs.
• Implement sensor sampling, calibration, filtering, event detection and alert logic.
• Develop local data logging, buffering and store-and-forward functionality.
• Implement watchdogs, fault recovery, communication retries and automatic restart.
• Develop low-power and battery-optimised firmware.
• Support remote configuration, diagnostics and OTA f
