Platform & Integrations Engineer

Full-time • Cape Town, South Africa • Remote

The Platform & Integrations Engineer is responsible for maintaining the reliability, integrity, and performance of Klarity’s core systems. The platform handles transactional POS operations, inventory reconciliation across multiple devices, offline-first processing, and third-party integrations. In a retail environment, even minor inconsistencies can erode trust, so this role focuses on ensuring that inventory and financial data remain accurate and predictable under real-world conditions.

This role requires a pragmatic, reliability-first mindset.
