The ideal candidate combines strong technical depth with systems thinking, hands-on validation skills, and excellent communication.
Key Responsibilities
Hardware Architecture & System Design
- Design IoT hardware systems (Gateways and BLE Sensors) integrating microcontrollers/SoCs, sensors, wireless modules, and power management subsystems.
- Design end-to-end systems from physical sensor measurements to processed data delivery to customer APIs
- Specify and evaluate low power components to maximize uptime under variable sunlight conditions.
- Generate schematics, PCB layouts, BOMs, and documentation in accordance with industry standards.
Power Management & Energy Optimization
- Model and optimize energy budgets to ensure year-round autonomous operation.
- Validate system performance through simulation, bench testing, and long duration field trials.
Sensor & Connectivity Integration
- Integrate a variety of sensors (environmental, motion, positioning, etc.) with proper front‑end conditioning.
- Implement and test wireless communication modules such as LoRaWAN, NBIoT, LTEM, LTE Cat 1, Bluetooth LE, or proprietary RF.
Prototyping, Testing, and Validation
- Build and iterate hardware prototypes rapidly using development kits, custom PCBs, and test equipment.
- Perform environmental, thermal, vibration, and ingress protection testing for ruggedized IoT devices.
- Conduct structured debugging across power, digital, RF, and firmware hardware interfaces.
Manufacturing & Deployment Readiness
- Support DFM, DFA and DFT practices
- Support certification processes (CE, FCC, EMC, IECex and safety compliance).
- Provide technical guidance for field deployment, maintenance tools, and diagnostics.
