Role Summary

RedRaven is Flowserve’s complete end-to-end solution for the industrial space to monitor and optimize flow control equipment performance and proactively identify and address issues before they cause downtime and disruptions.

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.
