Job Summary

We’re supporting a large international technology group on a long-term edge computing programme, and we’re looking for an experienced .NET Software Architect to take ownership of the architecture of an existing industrial IoT gateway solution.This is a senior, hands-on architecture role focused on offline-first edge systems, running in challenging, low-connectivity environments and deployed at scale across Europe and beyond.You’ll lead the evolution of an edge gateway solution running on industrial hardware, built around .NET, Linux, and Azure IoT Edge. A defining challenge of this system is that devices may operate offline for months or even years, requiring extremely robust local processing, storage, and controlled synchronisation once connectivity is restored.The platform currently supports hundreds of devices and is expected to scale into the thousands over the coming years.

Key Responsibilities

• Own and evolve the overall edge architecture (module structure, interfaces, runtimes, and operational concepts)
• Design and optimise offline-first workflows, including local persistence, retention, backfill, conflict handling, and safe re-synchronisation
• Architect and support Azure IoT Edge deployments, including versioning, rollbacks, monitoring, and troubleshooting
• Optimise local data flows and persistence across multiple on-device modules and databases
• Drive performance, reliability, and maintainability on resource-constrained edge hardware
• Define and enforce secure edge patterns (device hardening, secrets, certificates, secure local communication)
• Act as a technical authority through design reviews, architectural guidance, and root-cause analysis

Requirements / Qualifications

• Bachelor’s or Master’s degree, or equivalent professional experience
• 8+ years in software engineering / architecture roles
• 5+ years hands-on experience with edge computing or IoT edge systems (Azure IoT Edge strongly preferred)
• Strong experience with Linux on edge devices, including Yocto Linux
• Excellent .NET / C# skills (services, modular architectures, robustness patterns)
• Proven experience designing offline-first or intermittently connected systems
• Fluent English (written and spoken)

Preferred Qualifications

• Azure DevOps (pipelines, repos)
• Solid Azure Portal experience for fleet and edge operations
