Cape Town: Senior Backend (Full Stack) Software Engineer posted by Blue Pearl PTY LTD

We are seeking a highly experienced Senior Backend Engineer with 10+ years of professional software development experience to lead the design, development, and evolution of our core backend systems.

You will architect and maintain scalable .NET Core and .NET Framework services, design high-performance SQL Server solutions, and contribute to ETL pipelines and reporting processes. You will play a key role in defining backend standards, ensuring system reliability, and guiding the technical direction of our platform.

While this role is primarily backend-focused, you will collaborate closely with frontend engineers building Vue.js applications and will be encouraged to expand your influence across the application stack over time. The role offers a clear pathway to broader full-stack ownership, contributing to end-to-end solution design and frontendbackend alignment as part of your continued growth.

This position requires strong architectural judgment, production-grade system design expertise, and the ability to mentor engineers while upholding technical standards and long-term maintainability.

The ideal candidate is a strategic technical leader who remains hands-on while shaping system reliability, scalability, and engineering best practices.
