Job description

Overview

We are seeking a visionary Senior Backend Engineer with deep expertise in IoT ecosystems and M2M connectivity to lead the development of our next‑generation smart platform from scratch. In this role, you will architect the "nervous system" of our product, bridging the gap between physical hardware—such as telematics units and smart meters—and scalable cloud logic.

Key Responsibilities

• Architect from Scratch: Design and implement a greenfield, microservice‑based backend architecture optimized for high-throughput IoT data ingestion.
• Hardware & SIM Integration: Directly integrate diverse hardware (Telematics, Smart Meters) and manage the M2M SIM lifecycle (provisioning, activation, and data limit orchestration) via telco APIs.
• Protocol Implementation: Develop handlers for IoT protocols including MQTT, CoAP, HTTP/2, WebSockets, and LwM2M.
• Connectivity Management: Implement logic to monitor signal strength (RSSI), manage APN configurations, and handle fail‑over logic for devices using cellular M2M/eUICC technology.
• Logic Development: Build complex backend logic for smart solutions, such as geofencing, real‑time alerting, and automated data‑usage capping to prevent SIM overages.
• Data Orchestration: Manage massive streams of time‑series data using PostgreSQL (and TimescaleDB) to ensure data integrity and query performance.
• Security: Implement industry‑standard security including TLS/SSL, X.509 certificates, and Private APN/VPN tunneling for secure M2M communication.

Technical Requirements & Skillsets

• Core Backend & Infrastructure Frameworks: Mastery of Node.js and NestJS (TypeScript) is essential.
• Architecture: Proven experience in designing event‑driven architectures and microservices.
• Databases: Deep knowledge of PostgreSQL (schema design and performance tuning).
• IoT & Connectivity Expertise: M2M SIM Knowledge—Experience integrating with Connectivity Management Platforms (CMPs) like Cisco Jasper, Ericsson DCP, or 1NCE via REST APIs to manage SIM states and data consumption.
• Cellular Technologies: Understanding of NB‑IoT, LTE‑M (Cat‑M1), and 4G/5G constraints and how they impact backend polling and sleep‑cycle logic.
• Device Communication: Hands‑on experience with hardware‑to‑backend integration for Telematics (GPS, OBD‑II) and Smart Metering (DLMS/COSEM).
• Protocols: Expertise in MQTT/S, CoAP, and handling binary data payloads (Protocol Buffers, MessagePack).
• DevOps & Delivery: Containerization—Proficient with Docker and Kubernetes.
• CI/CD: Experience building automated deployment pipelines for scalable cloud environments.

Qualifications

• Education: Bachelor’s or Master’s degree in Computer Science, Telecommunications, or a related field.
• Experience: 5+ years in Backend Development, with at least 3 years specifically focused on IoT/M2M product ecosystems.
• Analytical Skills: Ability to troubleshoot network‑layer issues (packet loss, latency) specific to cellular M2M environments.
• Innovation: Demonstrated ability to take a product from a conceptual "scratch" phase to a production‑ready, global scale.

Preferred Qualifications

• Experience with eSIM/eUICC remote provisioning standards.
• Knowledge of Private APN setup and secure IPSEC/VPN tunneling between the Telco Core and the Cloud.
• Familiarity with hardware communication standards like RS‑485, CAN bus, or Modbus.
