Senior .Net Azure Developer

Senior .NET Developer – Kafka, Temporal & Azure Microservices

Position Overview

Design and build resilient, event-driven services powering an ecommerce and omnichannel fulfillment platform, including Ship-to-Store and related initiatives. This hands-on engineering role focuses on solving complex distributed-systems challenges involving ordering guarantees, workflow durability, fault tolerance, and high-scale retail environments.

The role works primarily with .NET, building microservices that communicate through Kafka and orchestrating long-running business processes using Temporal, with services deployed on Microsoft Azure.

What You'll Do / Key Responsibilities

• Design, build, and maintain scalable backend services using .NET/C# and ASP.NET Core for order management, inventory, and fulfillment workflows.
• Model and implement long-running, stateful business processes, including order-to-fulfillment and ship-to-store routing, using Temporal.
• Ensure workflow durability, retries, and compensation logic are handled correctly.
• Produce and consume events using Apache Kafka and design topics, partitioning strategies, and schemas that support high-throughput, low-latency processing.
• Architect and deploy services on Microsoft Azure using technologies including AKS, Azure Functions, Service Bus, Event Hubs, and API Management.
• Follow cloud-native and infrastructure-as-code practices.
• Write clean, well-tested, and maintainable code.
• Participate actively in code reviews, design reviews, and architectural decisions.
• Diagnose and resolve production issues across distributed services, including message ordering, idempotency, and eventual-consistency edge cases.
• Collaborate with Product Owners, architects, and QA to translate business requirements into robust technical designs.
• Contribute to CI/CD pipelines, observability, and overall engineering best practices.
• Mentor mid-level and junior developers and help raise the technical bar across the team.
• Evaluate and prototype emerging technologies, including applied AI/LLM capabilities, where they can improve the platform or developer workflow.

Required Qualifications

• 6+ years of professional software development experience with strong depth in .NET/C#, including ASP.NET Core and .NET 6+.
• Hands-on production experience with Apache Kafka, including producers and consumers, schema registry, partitioning, consumer group scaling, and failure-handling patterns.
• Practical experience with Temporal or comparable workflow orchestration engines, such as Camunda, AWS Step Functions, or Cadence, for durable execution of long-running business processes.
• Strong experience building and operating microservices on Microsoft Azure, including AKS/Kubernetes, Azure Functions, Service Bus, and Event Hubs.
• Solid understanding of distributed systems concepts, including idempotency, eventual consistency, retries/backoff, event sourcing, and the outbox pattern.
• Experience with relational and NoSQL data stores, including SQL Server or PostgreSQL, Cosmos DB, and Redis.
• Proficiency with containerization using Docker and Kubernetes-based deployment.
• Strong testing discipline, including unit, integration, and contract testing in a microservices environment.
• Experience with CI/CD tooling, such as Azure DevOps, GitHub Actions, or similar tools, and infrastructure-as-code using Terraform or Bicep.
• Excellent communication skills and comfort working directly with product and architecture stakeholders in an ecommerce/retail context.
• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience.
