Senior .Net Software Engineer, Cape Town

We are seeking a highly experienced Senior Software Engineer with 10+ years of professional software development experience to lead the design, development, and evolution of a back-end system.

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 back-end standards, ensuring system reliability, and guiding the technical direction of the platform.

While this role is primarily backend-focused, you will collaborate closely with front-end 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 frontend–backend 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.

What you'll do:

• Architect, design, and implement scalable backend services using .NET (C#)
• Lead system design decisions, ensuring scalability, reliability, and maintainability
• Optimise and maintain SQL Server databases and data access layers
• Guide integration design between back-end services and front-end Vue.js applications
• Drive improvements in code quality, testing standards, and DevOps practices
• Lead and participate in code reviews and architectural discussions
• Mentor intermediate and junior engineers
• Proactively identify technical risks and propose mitigation strategies
• Collaborate across distributed teams and influence technical direction
• Communicate progress, risks, and dependencies proactively

Your Expertise:

• Minimum 10+ years of professional software development experience
• Deep expertise in .NET Core / C# and building scalable, production-grade RESTful Web APIs
• Strong experience designing and maintaining distributed and enterprise-grade systems
• Advanced knowledge of Microsoft SQL Server, including schema design, indexing strategy, performance tuning, and query optimisation
• Experience implementing and optimising CI/CD pipelines (Azure DevOps or similar)
• Strong understanding of clean architecture, SOLID principles, and design patterns
• Demonstrated experience mentoring engineers and conducting technical reviews
• Excellent communication skills, with the ability to articulate architectural decisions, trade-offs, and technical strategy to both technical and non-technical stakeholders
• Demonstrated experience leading backend initiatives and delivering complex systems end-to-end across the full stack

Education & Qualifications:

• Bachelor's degree in computer science, Software Engineering or related field, or equivalent practical experience

Nice to Have:

• Strong exposure to Vue.js or other modern front-end frameworks
• Experience designing ETL workflows and data integration pipelines
• Exposure to cloud-native architecture or modernisation initiatives
• Experience with performance profiling and application monitoring
• Experience working in financial or investment domain
