Job Summary:

We are looking for a Embedded Systems Engineer to join our team to support customer deployments, proof-of-concept (POC) builds, and field testing for our modular IoT hardware ecosystem. In this role, you will work closely with hardware built on the RAKwireless ecosystem (core microcontrollers, wireless modules, and sensor boards). Your main goal will be to own technical troubleshooting, build practical demonstrations, run field coverage tests, and create comprehensive technical documentation. Ultimately serving as a key technical resource and reducing routine operational dependencies on senior SMEs.

Requirements

Key Responsibilities:

• Troubleshooting & Support: Reproduce, analyze, and troubleshoot customer-reported hardware, firmware, and integration issues in lab environments.
  
• POCs & Demos: Design, build, and deliver functional Proofs-of-Concept (POCs) and technical demonstrations using the RAKwireless WisBlock platform and related sensor/communication modules.
  
• Field Testing & Deployment: Conduct on-site and field tests to evaluate wireless coverage, range, power consumption, and reliability across various deployment scenarios (e.g., LoRaWAN, BLE, Cellular).
  
• Documentation & Knowledge Base: Document engineering results, field test data, and integration steps as technical reference guides, application notes, and case studies.
  
• SME Offloading: Take ownership of standard hardware/firmware queries to streamline customer support and significantly reduce routine support burdens on core SMEs.
  
  

Key Qualifications & Requirements:

• Educational Background: Bachelor’s degree in Electronics & Telecommunication Engineering, Embedded Systems, Electrical Engineering, or a related field.
  
• Hands-on Hardware Experience: 1) Practical experience working with modular development kits, LPWAN/IoT platforms preferred. 2) Familiarity with micro-controllers (e.g.,STM32, ESP32,) and sensor integration (I2C, SPI, UART, ADC).
  
• Wireless Technologies: Good understanding of LPWAN protocols (LoRa/LoRaWAN), Wi-Fi, BLE, or Cellular IoT.
  
• Firmware & Software: Proficiency in C / C++ (Arduino IDE, STM32CubeIDE, PlatformIO) and introductory scripting tools (e.g., Python) for testing and data logging.
  
• Technical Debugging: Experience with electronic debugging tools (multimeters, oscilloscopes, logic analyzers) and board-level troubleshooting.
  
• Communication Skills: Strong written and verbal technical communication skills to document case studies and interact clearly with both internal teams and external customers.
  
• Experience with network/protocol analyzers (e.g., Wireshark) or LoRaWAN Network Servers (ChirpStack, The Things Network).
  
• Basic understanding of PCB layout/schematics (KiCad, LTspice) to assist in root-cause analysis.
