Role SummaryAs 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 ResponsibilitiesDesign, implement, and maintain microservices and APIs with ASP.NET Core and Entity Framework CoreModel robust relational schemas and write high‑performance queries for SQL ServerBuild and integrate messaging & event systems (e.g., Azure Service Bus, RabbitMQ, Kafka) to enable decoupled, event‑driven workflowsApply Clean Architecture / Onion Architecture principles to keep codebases modular, testable, and maintainableOwn the full software‑delivery lifecycle: automated testing, CI/CD pipelines, containerization, logging, and telemetry on AzureConduct 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 scalabilityCore Tech Stack & ToolingLanguages & Frameworks: C#, .NET 5 - 8, ASP.NET Core, EF CoreCloud: 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, RedisDevOps: Docker, Azure DevOps CI/CD pipelines, GitObservability: Application Insights, OpenTelemetryRequirementsMust‑Have Qualifications6+ years of professional backend experience with .NET 5+ and C#Deep knowledge of ASP.NET Core, RESTful API design, and Entity Framework CoreProven expertise with SQL databases (schema design, query optimisation, indexing)—preferably SQL ServerHands‑on experience with messaging or event‑driven architectures in productionSolid grasp of Clean / Onion Architecture, SOLID principles, and automated unit/integration testingPractical 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 teamClear written & spoken English, proactive communication, ownership mindsetNice‑to‑Have SkillsAWS ecosystem familiarity (ECS/EKS, Lambda, SQS/SNS, etc.)Previous logistics/mobility domain experienceExperience with MongoDB or other NoSQL data storesConversational Arabic speakerScripting or tooling in PythonFront‑end exposure with AngularDevOps/SRE expertise: Docker, Kubernetes, Terraform, Helm, Pulumi, Observability stacksFamiliarity with CQRS, Event Sourcing, Domain‑Driven Design, or high‑throughput real‑time systems
