Description du poste

Are you a Backend Developer who enjoys building robust, scalable solutions and working with C# and ASP.NET? This could be your next exciting move!

Join a global BPO and technology-driven organisation that combines people, data, analytics and innovative technology. You will be joining an organisation that has been recognised as a Top Employer in South Africa, reflecting its focus on employee wellbeing, professional development and creating an enriching working environment.

As a Backend Developer, you will play an important role in building and enhancing reliable, scalable backend solutions that support the company's technology ecosystem.

If C# and ASP.NET are your strengths and you are looking for an opportunity where your development skills can contribute to large-scale, innovative technology solutions, we'd love to hear from you.

What Will Make You Stand Out:

• Strong C# / ASP.NET Core Web API experience
• Strong SQL expertise: complex queries, schema design, indexing, and query optimisation in SQL Server / Azure SQL
• EF Core proficiency, with the judgement to write raw SQL when the ORM is not the right tool
• Azure fundamentals: App Service (or equivalent), Blob, queues/Service Bus, identity/secrets
• Experience building integration-heavy or BFF-style APIs (timeouts, retries, token handling, clear error mapping)
• Solid testing habits (xUnit or similar)
• Comfortable in a fast-moving agile team collaborating with frontend and AI engineers

Experience That's a Plus:

• Experience with Cursor, Claude, or similar AI coding assistants
• Some exposure to AI/LLM APIs or AI-enabled products (helpful, not required)
• Entra ID / OAuth2 / managed identity
• Azure OpenAI or OpenAI API integration
• Bicep and Azure DevOps multi-stage deploys
• Debt-collection / BPO / fintech domain
• Comfort reading React consumers and collaborating on portal API contracts

Reference Number for this position is MAT61526 which is a permanent position based in Sandton offering a cost to company salary of up to R800K negotiable on experience and ability.
