Full description
The Applications Engineer designs and delivers digital solutions for manufacturing environments. This role sits at the intersection of Operational Technology (OT) and Information Technology (IT), developing applications and integrations that connect shop-floor systems to enterprise platforms.
You will analyse client requirements, architect scalable solutions, and implement secure, high-performance systems that improve operational efficiency, visibility, and data-driven decision-making.
This is a hands-on engineering role requiring strong technical capability, structured thinking, and the ability to operate across multidisciplinary teams.
Key Responsibilities1. Requirements & Solution Design
- Engage stakeholders to gather business, operational, and technical requirements across OT and IT environments.
- Develop clear technical specifications and solution designs.
- Ensure solutions account for networking, cybersecurity, data governance, and operational constraints.
2. Application Development
- Design, develop, configure, deploy, and maintain industrial software applications.
- Ensure solutions are scalable, secure, maintainable, and aligned with engineering standards.
3. SCADA & HMI Development
- Develop HMI screens and SCADA logic.
- Integrate data from PLCs, historians, databases, and IIoT platforms.
- Apply sound usability and operational design principles.
4. Database & Data Management
- Design and maintain database schemas and data models.
- Develop optimized SQL queries.
- Ensure data integrity, performance, and reliability across SQL (and relevant NoSQL) environments.
5. System Integration
- Design and implement APIs and messaging interfaces between:
- PLC/DCS systems
- IIoT platforms
- MOM/MES systems
- ERP systems
- Analytics platforms
- Apply appropriate protocols (e.g., REST, MQTT, OPC UA).
- Ensure secure, resilient, and interoperable integrations.
6. Architecture & Deployment Support
- Contribute to OT/IT system architecture and data flow design.
- Support deployment planning including:
- Server environments
- Networking
- Redundancy and backup strategies
- Long-term maintainability
