Role summary
As a senior backend software engineer, you will design, build, and maintain distributed services that power Ahoy’s movement and logistics platform. You will work primarily in C#/.NET 5+ on Azure, leveraging event-driven patterns, high-performance SQL, and modern architectural approaches (clean / onion) to deliver reliable, scalable services.
You’ll collaborate closely with product, DevOps, and front-end engineers, but also have the autonomy to drive solutions end-to-end—from whiteboarding architecture to shipping code and monitoring it in production.

Design, implement, and maintain microservices and APIs with ASP.NET Core and Entity Framework Core
Model robust relational schemas and write high-performance queries for SQL Server
Build and integrate messaging & event systems (e.g., Azure Service Bus, RabbitMQ, Kafka) to enable decoupled, event-driven workflows
Apply clean architecture / onion architecture principles to keep codebases modular, testable, and maintainable
Own the full software-delivery lifecycle: automated testing, CI/CD pipelines, containerization, logging, and telemetry on Azure
Conduct peer code reviews, mentor and guide junior as well as mid-level developers, and uphold engineering best practices (SOLID, TDD, DDD)
Diagnose production issues, optimize performance, and drive continuous improvement of service reliability and scalability
Core tech stack & tooling
Languages & frameworks: C#, .NET 5 – 8, ASP.NET Core, EF Core
Cloud: Microsoft Azure (App Service, Function Apps, Container Apps, Event Grid, Azure SQL, Azure DevOps)
