Job description

Role & responsibilities

• Design, develop, and maintain embedded electronics across multiple R&D products, including microcontroller-based control units, sensor interface boards, actuator drivers, and system wiring.
• Integrate and calibrate sensors across domains water quality, environmental, motion/IMU, optical, and others including signal conditioning, ADC, and noise rejection.
• Develop and maintain firmware (embedded C/C++) for real-time data acquisition, automatic calibration, outlier filtering, actuator control, and safety interlocks.
• Implement connectivity and telemetry over cellular (GSM/LTE), Wi‑Fi, BLE, or LoRa, with reliable store-and-forward for offline operation, an edge‑to‑cloud data pipeline (e.g., MQTT), and OTA firmware updates.
• Design and validate power electronics and power management: battery / UPS systems, charging, generator or solar interfacing, auto-changeover, and load management for uninterrupted operation.
• Engineer hardware for harsh deployment conditions: vibration and shock, humidity and water ingress (IP-rated enclosures), thermal management, and EMI/EMC robustness.
• Own PCB schematic capture and layout, component selection and BOM, prototype bring‑up, and debugging.
• Support edge-AI, sensor‑fusion, and predictive‑maintenance features by ensuring high-quality, well‑characterised sensor data and instrumentation.
• Build rapid prototypes to validate new R&D concepts, and help mature the promising ones into reliable products.
• Support field trials, installation, and on‑site troubleshooting; lead root‑cause analysis of failures.
• Produce and maintain clean documentation: schematics, wiring diagrams, test procedures, calibration records, and as‑built configurations.

Preferred candidate profile

• B.E./B.Tech in Electronics, Electronics & Communication, Instrumentation, or Electrical Engineering (or equivalent practical experience).
• 36 years of hands‑on experience in embedded systems / IoT hardware development.
• Proficiency in embedded C/C++ on ARM Cortex-M class microcontrollers (e.g., STM32, ESP32, NXP); familiarity with an RTOS.
• Strong sensor‑interfacing skills: IC, SPI, UART, analog signal conditioning, and ADC fundamentals.
• PCB design experience with a standard EDA tool (Altium, KiCad, or Eagle), including layout and bring‑up.
• Working knowledge of wireless connectivity (cellular, Wi‑Fi, BLE, LoRa) and IoT messaging protocols.
• Fundamentals of power electronics and battery management.
• Comfortable with lab instruments - oscilloscope, multimeter, logic analyser - and with soldering and rework.

Preferred / nice‑to‑have

• Experience with IoT sensing, instrumentation, or environmental monitoring systems.
• Exposure to marine, robotics, autonomous‑platform, or machine‑vision hardware.
• Edge AI / TinyML, sensor fusion, or data‑driven calibration techniques.
• Rugged, automotive, or outdoor electronics; EMC compliance and IP‑rated enclosure design.
• Cloud IoT platforms (AWS IoT, Azure IoT) and OTA update mechanisms.
• Python for test automation and data analysis.

What success looks like

• Reliable, field‑proven electronics and sensor stacks that run unattended through real deployments, including loss of connectivity and power transitions.
• Sensor data trustworthy enough to drive automation, analytics, and predictive features.
• Fast, dependable turnaround from R&D concept to working prototype, and from prototype to robust product.
