With a new engineering hub in Belfast, they're investing in building core trading systems and infrastructure locally. The Belfast team is focused on developing high-performance, real-time systems to support a major trading platform launch in 2026.

The Role
We're looking for a Mid/Senior QA Engineer with 3+ years of automation experience to join the founding Belfast engineering pod. You'll help deliver high-quality software by building automated test pipelines, integrating QA into CI/CD processes, and ensuring the reliability and performance of real-time systems.

This is an exciting opportunity to contribute to QA strategy, influence testing best practices, and gain exposure to complex, high-performance trading systems from the ground up.

Key Responsibilities

• Build and maintain automated test suites for back-end services, APIs, and data pipelines
• Identify and report defects, working closely with developers to resolve issues quickly
• Integrate automated testing into CI/CD pipelines to support continuous delivery
• Support QA strategy and contribute to testing standards and best practices
• Collaborate with engineers to design testable architectures and identify early failure points
• Contribute to release management and system validation for production deployments

Ideal Candidate Profile

• 3+ years' experience in QA or software engineering with a focus on automation
• Hands-on experience building automated test frameworks in Java, Python, or similar
• Understanding of distributed systems, APIs, and event-driven architectures
• Experience with CI/CD pipelines, containerisation (Docker, Kubernetes), and cloud environments (AWS preferred)
• Exposure to financial systems, real-time data processing, or trading platforms is desirable but not essential

Essential Criteria

• Strong experience in automated testing for back-end systems
• Excellent debugging, problem-solving, and analytical skills
• Collaborative mindset and ability to thrive in a fast-paced, engineering-driven environment
• Degree in Computer Science, Software Engineering, or equivalent experience
