Oliver James Associates - Senior Azure / .NET Architect

We're reimagining a mission-critical communication platform that powers how systems exchange data, files, and events with the outside world. This is not a greenfield toy project-it's a high-impact transformation at scale. As a Senior Azure .NET Architect, you'll help design and shape a next-generation, cloud-native integration platform. You'll take an existing, complex ecosystem and turn it into a resilient, high-performance, event-driven architecture running on Azure. If you enjoy solving hard distributed systems problems and building platforms that truly matter-this role is for you.

💡 What you'll be doing

• Design and build a modern communication layer handling message and file ingestion, transformation, routing, and delivery (sync + async)
• Create resilient, fault-tolerant systems using proven patterns like retries, circuit breakers, idempotency, and event-driven workflows
• Architect scalable event-driven solutions using Azure messaging services and/or Kafka-style pub/sub systems
• Build high-quality .NET services (.NET 7/8, C#, ASP.NET Core, gRPC/REST) with a strong engineering culture (TDD, clean code, performance-first)
• Deploy and operate workloads on Kubernetes (AKS/OpenShift) using Helm and modern CI/CD pipelines
• Define observability from day one: logging, tracing, metrics, SLOs, and actionable runbooks
• Collaborate in a truly agile setup, working closely with engineers, product owners, and other teams
• Mentor and elevate others-your experience will help raise the bar across the team

🎯 Why this role stands out

• High impact: You're building a core platform that everything depends on
• Real engineering challenges: Distributed systems, scalability, resilience-no trivial work here
• Modern tech stack: Cloud-native, Kubernetes, event-driven, .NET latest
• Ownership & influence: Your architectural decisions will shape the platform long-term
• Collaborative culture: Work with experienced engineers who care about doing things right

• Extensive experience in software engineering (15+ years), including building distributed, high-throughput, or mission-critical systems
• Strong hands-on Azure expertise (AKS, Functions, messaging services, Storage, monitoring, CI/CD)
• Deep knowledge of .NET (C#, modern .NET, async programming, testing practices)
• Solid understanding of event-driven architecture and distributed system trade-offs
• Experience with Docker and Kubernetes in production environments
• A mindset focused on quality, automation, and continuous improvement
• Confidence to make architectural decisions and guide others
• Strong communication skills in English

• Experience with observability stacks (Opentelemetry, tracing, logging platforms)
• Exposure to large-scale messaging or file transfer systems
• Knowledge of secure integration protocols (e.g., sFTP, AS2/AS4, messaging queues)
• Experience working in regulated or high-reliability environments
