Senior IoT Full Stack Engineer (M2M & Smart Platform Solutions)

Job Title: Senior IoT Full Stack Engineer (M2M & Smart Platform Solutions)

Job Overview

We are looking for a high-caliber Senior IoT Full Stack Engineer to lead the architectural design and development of our smart platform from the ground up. This isn't just a standard web role; you will be the bridge between the physical and digital worlds.

You will be responsible for building high-performance, real-time applications that directly interface with hardware—ranging from telematics and smart meters to specialized industrial sensors. You will design the protocols for data ingestion, manage the M2M connectivity layer, and deliver a world-class user experience for monitoring and controlling these assets in real-time.

Key Responsibilities

• Architect from Scratch: Design and build a greenfield, microservices-based ecosystem using NestJS (Backend) and Next.js (Frontend) tailored for massive IoT data throughput.

• Direct Hardware Integration: Develop and implement direct communication layers for diverse IoT devices and sensors, ensuring stable data ingestion from telematics units and smart meters.

• IoT Protocol Mastery: Implement and optimize communication using MQTT, CoAP, WebSockets, gRPC, and HTTP/2 to ensure low-latency, bi-directional messaging.

• M2M & Connectivity Management: Orchestrate the M2M SIM lifecycle, integrating with Connectivity Management Platforms (CMPs) to monitor data usage, signal strength, and cellular connectivity states.

• Real-Time Logic & Analytics: Build complex backend logic for smart solutions, including geofencing, real-time alerting, predictive maintenance, and time-series data visualization.

• Data Strategy: Design high-performance database schemas in PostgreSQL (utilizing TimescaleDB for time-series data) to handle millions of incoming data points.

• Frontend Excellence: Create intuitive, real-time dashboards in Next.js that visualize live device states, historical trends, and complex sensor telemetry.

• End-to-End Security: Implement robust security for the IoT edge-to-cloud path, including X.509 certificate-based authentication and private APN/VPN configurations.

Technical Requirements & Skillsets

Backend & IoT Core

• Expertise: Advanced Node.js / NestJS (TypeScript) with a focus on event-driven architecture.

• IoT Standards: Deep experience with MQTT brokers (EMQX, HiveMQ, or Mosquitto) and binary data formats (Protocol Buffers, MessagePack).

• M2M Knowledge: Proven experience managing M2M/eUICC SIMs, APN configurations, and cellular network constraints (NB-IoT, LTE-M).

• Database: Mastery of PostgreSQL; experience with time-series optimization and caching layers (Redis).

Frontend & Real-Time

• Frameworks: Expert knowledge of Next.js (React) and state management (Zustand, Redux, or React Query).

• Visualization: Experience with real-time data streaming to the UI via WebSockets/SSE and data visualization libraries (D3.js, Highcharts, or Mapbox for telematics).

Infrastructure & DevOps

• Microservices: Solid experience with Docker, Kubernetes, and message brokers (Kafka or RabbitMQ).

• CI/CD: Designing automated pipelines for rapid, reliable deployments.

Requirements:
• Experience: 5+ years in Full Stack Development, with at least 3 years of hands-on experience in IoT/M2M product environments.

• Hardware Fluency: Ability to read hardware documentation and implement direct integrations via TCP/UDP or specialized protocols (Modbus, DLMS/COSEM).

• Real-Time Focus: A proven track record of building applications where latency and data integrity are mission-critical.

• Education: Bachelor’s or Master’s degree in Computer Science, Telecommunications, or Electrical Engineering.

Preferred Qualifications

• Experience with eSIM remote provisioning and global roaming orchestration.

• Knowledge of Edge Computing (processing data at the gateway level).

• Background in Telematics (OBD-II, CAN bus) or Smart Grid technologies.
