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

You won't just "contribute"-you'll shape the future architecture:

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#, 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

bonus points

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
