About The Role
We are looking for a passionate Solution Architect to lead end-to-end IoT solutions, with a high focus on data enablement and AI-driven applications, in cloud and hybrid environments.

You will bring your expertise in Data & AI and your knowledge and passion of IoT ecosystems to design and guide the implementation of robust and scalable platforms, and Data & AI driven applications. Working collaboratively, you will be leading the assessment of options, designing the architecture, and guiding teams on the implementation of solutions for our enterprise customers.

From monitoring connectivity of IoT devices, through data aggregation and analytics, to workflow automation or blockchain-enabled applications, you will be at the forefront of innovation and value creation for our customers. These applications deliver major value for their products and their business efficiency, including real-time analytical capabilities, service monitoring, anomaly detection and correlation using online machine-learning.

Responsabilities

• Define and evolve modular, scalable, and future-proof architectures for IoT-related solutions. Enable hyperautomation across IoT ecosystems by integrating data, AI, and workflow orchestration into intelligent, event-driven architectures.
• Select and map the appropriate technology components for architecture and solution requirements. Continuously evaluate and test new technologies, platforms, products, and cloud services when needed.
• Act as a technical lead and key reference for customers. Define integration architecture with external systems, identifying technical dependencies, risks, and solutions.
• Drive continuous improvement in architecture strategies and technology for IoT solutions.
• Collaborate with business teams to align technical capabilities with monetization strategies.
