Job description

About the Role :

We are seeking an experienced Telecommunications & IoT Hardware Engineer to lead the technical evaluation, integration, testing, and deployment of our next-generation wireless GPS asset-tracking devices. In this role, you will serve as the core technical authority bridging wireless firmware/hardware configurations with live telematics platforms.

You will work directly with multi-positioning IoT hardware (GNSS, Cellular 4G LTE/Cat-M1/NB-IoT, Wi-Fi sniffing, and BLE 5.0+) to ensure real-time tracking accuracy, power management efficiency, network carrier certification, and seamless protocol integration.

Preferred candidate profile :

Key Responsibilities

• RF & Wireless Protocol Integration: Configure, calibrate, and troubleshoot wireless communication modules across cellular (GSM/LTE/Cat-M1/NB-IoT), GNSS (GPS, GLONASS, Galileo), Wi-Fi positioning, and Bluetooth Low Energy (BLE).
• Firmware & Protocol Configuration: Parse and implement device protocols (TCP/UDP, MQTT, CoAP, HTTP), custom AT commands, and payload structures for real-time telematics platforms.
• Power Optimization & Battery Profiling: Analyze and optimize device power states (deep sleep, motion-activated wakeup, periodic pings, GPS fix acquisition time) to maximize battery life for long-deployment asset trackers.
• Testing & Quality Assurance: Conduct bench testing, RF signal validation, over-the-air (OTA) firmware upgrade verification, and field stress-testing (drive testing, indoor/fringe signal degradation, multipath interference).
• Carrier & Regulatory Compliance: Coordinate device onboarding and certifications (PTCRB, FCC, AT&T/Verizon/T-Mobile carrier acceptance, CE) and troubleshoot SIM/eSIM provisioning issues.
• Vendor & Hardware Evaluation: Interface with global hardware manufacturers, evaluate sample units, review PCB schematics, antenna designs, and bill of materials (BOM) to recommend hardware selections.
• L3 Technical Escalation: Provide root-cause analysis for field transmission failures, packet loss, GNSS drift, and connectivity dropouts.

Required Qualifications

• Education: Bachelors degree in Telecommunications Engineering, Computer Engineering, or related technical field (or equivalent practical experience).
• Experience: 2+ years of hands-on experience in telematics, wireless IoT devices, or connected hardware product lifecycles.
• Wireless Domain Expertise:
  • GNSS: Deep understanding of GPS, GLONASS, Assisted-GPS (A-GPS), TTFF (Time-to-First-Fix), and antenna tuning.
  • Cellular: Strong background in 3G/GSM legacy protocols, 4G LTE, Cat-1, Cat-M1, NB-IoT, and baseband modem operation.
  • Short-Range Wireless: Practical experience with BLE (beacons, sensors, RSSI locationing) and Wi-Fi SSID location sniffing.
• Network & Data Protocols: Proven ability to work with TCP/IP, UDP, MQTT, JSON, binary packet parsing, and cellular AT command sets.
• Tools & Equipment: Experience using spectrum analyzers, oscilloscopes, RF power meters, Wireshark, serial debug terminals (e.g., PuTTY, Tera Term), and device management platforms.

Preferred but not required Qualifications

• Prior experience with commercial fleet management, supply chain asset tracking, or cargo monitoring systems.
• Experience writing automation scripts in Python, C/C++, or Bash for bench testing and payload decoding.
• Working knowledge of eSIM/eUICC profile switching and multi-carrier roaming architecture.
• Experience managing regulatory submissions (FCC Part 15/22/24, PTCRB, UN38.3 battery transport compliance)
