Senior Full Stack Engineer; Cloud and Data Systems; CH

Our client, a Stellenbosch-based Fin Tech business operating in trade and collateral-risk technology, is looking to appoint a Senior Full Stack Engineer to join its Sentinel engineering team.

This role is suited to a senior hands-on developer who can deliver complex full-stack features, protect architectural integrity, contribute to secure software delivery, and provide technical guidance to other developers.

Role Focus

• Lead the implementation of high-impact full-stack features and technically sensitive work streams.
• Build and maintain robust frontend, backend, database, API and integration components.
• Support architecture-safe delivery by reviewing design choices, data boundaries, secure access patterns and maintainability.
• Review pull requests, improve code quality and mentor junior and mid-level developers.
• Contribute to release readiness, technical risk identification and engineering standards.

Primary Requirements

• 6+ years' professional software development experience.
• Strong full stack development experience across frontend, backend, databases, APIs and integrations.
• Experience leading complex software features, technical work streams or cross-module implementations.
• Strong code-review capability, with experience mentoring or guiding other developers.
• Solid architectural thinking, secure coding discipline and ability to identify technical risk.
• Strong SQL, data modelling, migration and performance-tuning exposure.
• Experience in fintech, financial services, data-platform, security-conscious or regulated environments will be advantageous.

Preferred Technical Exposure

• Modern frontend and backend frameworks, preferably including React/Type Script and Python/Django, or a comparable full-stack technology environment.
• AWS, CI/CD, observability, logging and diagnostics.
• Authentication, authorization, role-based access control and secure-by-default implementation patterns.
• Cloud infrastructure or infrastructure-as-code exposure, such as Terraform, will be beneficial.

Ideal Candidate

The ideal candidate is a builder-leader: someone who still writes excellent code, but also knows when to review, guide, challenge technical decisions and protect the quality of the platform.
