Senior QA Engineer (Technology/Mining)

Our client is a growing technology company that revolutionises mining logistics across South Africa. Their platform connects mines and hauliers, automating vehicle tracking, order management and weighbridge operations using NFC technology and IoT devices integrated with AWS Cloud.

They are seeking developers who genuinely love coding and continuously upskill themselves. Their collaborative environment encourages innovation, includes developers in technical decisions and supports both hybrid and in-office work arrangements. They invest in learning opportunities for those willing to put in effort, and because their clients operate 24/7, they value team members who can occasionally assist with critical support.

Role Overview

Our client is seeking an experienced Senior QA Engineer to spearhead their testing strategy and build a comprehensive QA practice that ensures the reliability of mining operations across South Africa. You'll initially focus on manual testing while progressively designing and implementing automation frameworks across our client’s technology stack, including desktop (React + Electron), mobile (React Native + Expo) and web (React) applications.

This role requires handling complex testing scenarios including hardware integrations with weighbridge indicators, IoT devices, cameras and NFC scanning across 50+ remote mining sites. You'll establish multi-tiered testing environments and work independently to build a QA practice from scratch, with the opportunity to eventually lead a team as our client expands into new markets.

Their core values include Focus on the Mission, Respect, Excellence, Integrity and working as One Team.
