This organisation is a leading international energy trading business, specialising in the trading and optimisation of Oil, Natural Gas, Power, and LNG across global markets. Its technology function is responsible for developing and supporting the platforms, applications, infrastructure, and distributed systems that enable front-to-back trading operations, ensuring systems are secure, resilient, and capable of supporting high-volume, real-time trading activity. This includes supporting event-driven architectures and technologies such as Kafka that underpin business‑critical data flows across the organisation.

Within this environment, a QA Engineer plays a key role in maintaining the quality of software releases by working closely with Product, Development, and Business teams to identify defects, and ensure critical trading applications and distributed systems perform reliably. Acting as a key quality gate throughout the software delivery lifecycle, you will help minimise operational risk, improve system stability, and ensure technology solutions meet the high standards required within a fast‑paced, business‑critical energy trading environment.

As a Senior QA Engineer, you will take ownership of building proof‑of‑concepts (POCs), developing automation frameworks from scratch, and introducing a Shift Left mindset across teams. It’s a hands‑on position where you’ll shape the QA function and play a key part in improving quality and delivery across the business, with exposure to testing Kafka‑based integrations and complex distributed systems
