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
