Quality Assurance Engineer

At Embelo, we're dedicated to helping founders of consulting businesses start and scale efficiently. Backed by our UK-based investors and clients, we deliver exceptional client services to a growing group of UK businesses, combining technical expertise, South African spirit, and the latest in AI-powered services. One of those is Inference Group, a fast-growing data and AI consultancy on a mission to help businesses unlock their true potential and drive sustainable growth.

We’re growing our Data and Integration team in Cape Town and are looking for an experienced QA Engineer to take ownership of testing across our data platforms, applications and system integrations.

The immediate focus of this role is ensuring that the solutions we build are reliable, accurate and ready for production. You’ll test APIs, integrations, data flows and platform functionality, combining hands‑on testing with automation and strong SQL‑based data validation.

This isn’t a role where you’ll simply be handed detailed test scripts to execute. We’re looking for someone experienced enough to take a requirement or solution design, understand what needs to be tested, identify the risks and edge cases, and independently build and execute an appropriate test approach.

You’ll work across API testing, integration testing, regression testing and data validation
, while helping us increase the level of test automation across our delivery teams. You’ll also support UAT, manage defects through to resolution and work closely with developers, data engineers, integration specialists and client stakeholders.

This is a consulting environment, so strong communication and judgement matter alongside technical testing capability. You’ll need to be comfortable asking the right questions, challenging assumptions when necessary and taking ownership of quality from requirement through to release.

Location: This is a hybrid role based in Cape Town, with a minimum of three days per week in our Woodstock office. Candidates looking to relocate to Cape Town are welcome to apply, although relocation costs would need to be covered personally.

• Own testing across applications, APIs, integrations and data platform solutions from requirement through to release.

• Perform functional, integration, system and regression testing across end‑to‑end solutions.
• Build and maintain automated tests to improve coverage, repeatability and delivery speed.
• Identify edge cases and potential failure points across complex integrations and data flows.
• Log, prioritise and manage defects, working closely with engineering teams to investigate root causes and verify fixes.
• Support and coordinate User Acceptance Testing (UAT), helping stakeholders understand expected outcomes and resolve issues.
• Test changes across interconnected systems to ensure new releases do not introduce unintended impacts elsewhere.
• Contribute to improving QA processes, test coverage and automation practices across the team.
• Work within an agile delivery model, contributing to sprint planning, stand‑ups, reviews and release activities.
• Communicate testing progress, risks and quality concerns clearly to technical teams, delivery leads and client stakeholders.
