🚀 Senior Azure .NET Architect - Build the Backbone of Modern Messaging

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#, 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.

🧠 What You Bring

  • 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.

🎯 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.
