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.
