Oliver James Associates - Senior Azure / .NET Architect

ictjob.be; Brussel; On-site; EUR 90,000 - 120,000; Full time

Job summary

ictjob.be seeks a Senior Azure .NET Architect to help design a cloud-native, high-performance integration platform. You’ll transform a complex ecosystem into an event-driven architecture on Azure, focusing on reliability and scale.

You'll build .NET services (NET 7/8, C#, ASP.NET Core, gRPC/REST), deploy on Kubernetes (AKS/OpenShift), implement CI/CD, and shape observability from day one. If you love tough distributed systems problems, this is for you.

Qualifications

• Experience designing cloud-native architectures.
• Proven track record with .NET and Azure.
• Strong distributed systems background.

Responsibilities

• Design and build a modern communication layer handling message and file ingestion, transformation, routing, and delivery (sync + async).
• Create resilient, fault-tolerant systems using 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 an 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.

Job description

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

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
