Join a forward-thinking SaaS solutions company that’s transforming the logistics and warehousing industry through cutting-edge software. You’ll play a key role in developing a major Warehousing and Procurement platform for a large client in the Western Cape — working closely with international teams and the Technical Director.

You’ll contribute to shaping technical direction, drive best practices, and ensure scalability and security across enterprise systems.

You’ll work with a modern, cloud-native tech stack including Azure Functions, AKS, Service Bus, Terraform, and CI/CD pipelines in Azure DevOps or GitHub Actions. Collaboration, technical excellence, and innovation are at the heart of this environment.

Role entails:

Cloud Architecture & Integration

• Integrate and optimise applications using Azure App Service, Functions, Service Bus, Key Vault, and Azure SQL Database.
• Implement observability and diagnostics through Azure Monitor, Application Insights, and Log Analytics.
• Apply Infrastructure-as-Code using Terraform, Bicep, or ARM Templates.

DevOps & Automation

• Design and manage CI/CD pipelines with Azure DevOps or GitHub Actions.
• Enable containerisation and cloud deployments via Azure Container Apps or AKS (Kubernetes).
• Implement automated testing, code quality checks, and modern deployment strategies.

Collaboration & Governance

• Participate in Agile/Scrum ceremonies, peer reviews, and technical design discussions.
• Promote knowledge sharing and ensure adherence to internal governance and security standards.

Leadership & Mentorship

• Mentor junior developers, fostering a culture of continuous improvement and technical excellence.
• Contribute to internal frameworks, reusable components, and best-practice processes.
• Stay current with developments in the .NET, React, and Azure ecosystems to ensure ongoing innovation.

Core Technical Stack

• Backend: .NET 8/9, ASP.NET Core, C#, Web API, Entity Framework Core, LINQ
• Frontend: React v19, TypeScript, JavaScript (ES6+), Redux / Context API, Material UI
• Database: Azure SQL Database, T-SQL, Query Optimisation
• Cloud & DevOps: Azure App Service, Functions, AKS, Service Bus, Blob Storage, Key Vault, Azure DevOps
• Testing: xUnit / NUnit, Jest / React Testing Library
• CI/CD & IaC: Azure Pipelines, Application Insights, Terraform / Bicep
• Architecture Patterns: REST, Microservices, CQRS, Clean Architecture, Domain-Driven Design (DDD)

If you’re a senior developer who enjoys solving complex problems, delivering high-quality code, and working with the latest technologies in a flexible hybrid setup (1–2 days in Bryanston) — this is the ideal next step.
