Integration Engineer

JLL
Mountain View, CA Full Time
POSTED ON 12/12/2025 CLOSED ON 1/4/2026

What are the responsibilities and job description for the Integration Engineer position at JLL?

What this job involves - As an Integration Engineer, you are the technical bridge between our client’s physical infrastructure (lab equipment, BMS, sensors) and our cloud-based platforms. You will be responsible for configuring, deploying, and maintaining the connectors and gateways that allow critical facility data to flow into a leading global cloud service provider.

You will work closely with the Technical Services team and Data Architects to operationalize critical building data. Your focus is on the "plumbing" of our digital ecosystem—ensuring that diverse systems (HVAC, lighting, lab assets) can communicate reliable data to our analytics tools.

Key Responsibilities

System Connectivity & Ingestion

  • Implement and configure data ingestion pipelines from various sources (e.g., BMS, equipment logs, IoT sensors) into GCP services like Pub/Sub.
  • Deploy and manage edge gateways or middleware that translates standard building protocols (BACnet, Modbus, LonWorks) into cloud-ready formats (MQTT, JSON).
  • Operationalize critical building/space data, ensuring that raw telemetry from lab equipment is correctly tagged, standardized, and transmitted to the cloud.

API & Workflow Integration

  • Build and maintain API integrations between third-party operational applications (e.g., CMMS, ticketing systems) and our client’s internal ecosystem.
  • Write scripts (Python or Node.js) to automate data transfers between disconnected systems, eliminating manual data entry.
  • Monitor data flow health, troubleshooting connectivity dropouts or API errors to ensure continuous data availability for the analytics team.

Hardware & OT Support

  • Collaborate with HVAC and Electrical teams to identify available data points on physical equipment and determine the best method for extraction.
  • Stay abreast of developments in cloud-based operational technology (OT) solutions, testing new sensors or integration methods as directed by leadership.
  • Support the Technical Services team in troubleshooting networked equipment issues that impact data visibility.

Sound like you? To apply you need:

  • 2-4 years of experience in systems integration, controls engineering, or IoT implementation.
  • Strong understanding of Operational Technology (OT) protocols, specifically BACnet, Modbus, and MQTT.
  • Hands-on experience operationalizing Building Management Systems (BMS) or similar critical facilities data.
  • Proficiency in scripting languages (Python or JavaScript) for writing API connectors and data transformation scripts.
  • Familiarity with Pub/Sub and Cloud Functions.
  • Experience with APIs (REST/SOAP) and understanding of how to authenticate and query third-party software.
  • Basic networking knowledge (IP addressing, firewalls, gateways) as it pertains to connecting industrial equipment to IT networks.
  • Problem-solving mindset: You enjoy figuring out how to make two systems "talk" that weren't originally designed to work together.
  • Bachelor's degree in Engineering, Computer Science, or a related technical field.
