Field Application Engineer (IoT)

1.Technical Pre-sales Role

• Work closely with sales and marketing to support customer evaluations and decision-making (design-in stage)
• Provide roadmap/new product/technical update, proof-of-concept (PoC) guidance.
• Analyse customer needs and map them to suitable IoT solutions (e.g., sensors, modules, gateways, protocols).

2. Customer Integration Support

• Assist customers with hardware and firmware integration:
  • Cellular & non-cellular modules
  • Antenna and RF layout guidance
  • Installation guidance
  • Identify optimal sensor/gateway placements for maximum coverage and reliability
  • Help with embedded software development, including:
  • SDKs, AT commands, or AppZone (usually for cellular modules)
  • Domain-expert in IoT protocols like MQTT, CoAP, HTTP, etc.
  • Basic know-how on cloud connectivity (AWS IoT, Azure IoT, etc.)

3. Testing & Debugging

• Help customers debug issues during development and deployment:
  • Connectivity problems (e.g. LTE bands, network issues)
  • Firmware bugs or hardware misconfigurations
  • Certification compliance (e.g., CE, FCC, other RF Certificates)
• Conduct RF performance validation, device benchmarking, and field testing.

4. System Architecture Guidance

• Recommend best practices for:
  • Edge computing, data processing, over-the-air (OTA) updates
  • Device-to-cloud architectures
  • Security (TLS, encryption, secure boot)

5. Post-Sales Support & Training

• Support customers during product ramp-up stage
• Provide on-site or remote troubleshooting
• Conduct technical workshops or training for customer teams
• PCN update and RMA support
