Senior IoT Engineer – ThingWorx Specialist

We are looking for a Senior IoT Engineer with deep expertise in PTC ThingWorx and the surrounding IoT ecosystem (Azure, MQTT, databases, and data historians). The candidate will architect, develop, and optimize ThingWorx‑based IoT solutions for device connectivity, real‑time analytics, visualization, and system integration.

This role also requires hands‑on experience in developing custom ThingWorx Java Extensions and strong problem‑solving skills in distributed, data‑heavy environments.

Responsibilities

ThingWorx Platform Development

• Design and develop complex ThingWorx services, DataShapes, ThingTemplates, and Mashups for large‑scale industrial IoT solutions.
• Implement scalable logic for data ingestion, transformation, visualization, and event‑based analytics.
• Optimize ThingWorx services for performance, memory usage, and large InfoTable handling.
• Configure and manage Value Streams, Data Tables, and persistence providers (PostgreSQL, InfluxDB, etc.).
• Build dynamic UI dashboards and KPI visualizations aligned with asset hierarchies and customer‑specific contexts.

Custom Extension Development (Java SDK)

• Develop ThingWorx Java Extensions using the ThingWorx SDK for custom functionalities beyond platform capabilities.
• Implement reusable Java‑based services, event handlers, or connectivity modules.
• Manage extension lifecycle: design, build, sign, package, and deploy via the ThingWorx Composer.
• Integrate with external systems (e.g., MQTT, Kafka, RabbitMQ, PI Web API, REST, SOAP) through secure and performant extension code.
• Follow best practices for logging, exception handling, threading, and resource management in extensions.

Integration & Data Handling

• Work with Azure IoT Hub/Event Hub, RabbitMQ, or MQTT brokers for large‑scale device communication.
• Design and implement data pipelines between ThingWorx, external databases (Postgres, InfluxDB), and cloud storage systems.
• Integrate time‑series historians (e.g., OSI PI Web API, AVEVA Historian, etc.) for historical and batch analytics.
• Implement efficient batch APIs, JSON parsing, and bulk processing mechanisms.

Architecture & System Design

• Define and document ThingWorx architecture, entity design standards, and naming conventions.
• Evaluate and improve scalability, security, and maintainability of IoT deployments.
• Collaborate with IT teams for infrastructure activities.
• Support CI/CD integration, version control (Git), and automated deployments for ThingWorx artifacts.

Requirements

• Bachelor’s or Master’s degree in Computer Science, Electronics, or related engineering field.

Preferred Experience / Skills

• Strong problem‑solving and debugging mindset for complex multi‑system IoT issues.
• Excellent documentation, design, and communication skills.
• Ownership‑driven attitude with a focus on scalable and sustainable design.
• Experience vibration monitoring systems.
• Exposure to Edge device integration (LoRaWAN, Modbus, OPC‑UA, etc.).
• Knowledge of Docker‑based ThingWorx deployments or Kubernetes.
