Senior Backend Software Engineer (.NET)

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 white‑boarding architecture to shipping code and monitoring it in production.

Key Responsibilities

• 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)
• Data & Messaging: SQL Server, PostgreSQL (optional), Azure Service Bus / RabbitMQ / Kafka, Redis
• DevOps: Docker, Azure DevOps CI/CD pipelines, Git
• Observability: Application Insights, OpenTelemetry

Requirements

Must‑Have Qualifications

• 6+ years of professional backend experience with .NET 5+ and C#
• Deep knowledge of ASP.NET Core, RESTful API design, and Entity Framework Core
• Proven expertise with SQL databases (schema design, query optimisation, indexing)—preferably SQL Server
• Hands‑on experience with messaging or event‑driven architectures in production
• Solid grasp of Clean / Onion Architecture, SOLID principles, and automated unit/integration testing
• Practical experience building and maintaining CI/CD pipelines (Azure DevOps, GitHub Actions, GitLab, etc.)
• Excellent communication skills and a track record of mentoring or technical leadership within a team
• Clear written & spoken English, proactive communication, ownership mindset

Nice‑to‑Have Skills

• AWS ecosystem familiarity (ECS/EKS, Lambda, SQS/SNS, etc.).
• Previous logistics/mobility domain experience.
• Experience with MongoDB or other NoSQL data stores.
• Conversational Arabic speaker.
• Scripting or tooling in Python
• Front‑end exposure with Angular
• DevOps/SRE expertise: Docker, Kubernetes, Terraform, Helm, Pulumi, Observability stacks
• Familiarity with CQRS, Event Sourcing, Domain‑Driven Design, or high‑throughput real‑time systems
