Job description

QX builds innovative, scalable and secure AI-driven solutions that solve real business problems. Our work spans self-service tools, Generative AI applications and Agentic Process Automation, with a strong focus on creating user experiences that are practical, effective and measurable.

We deploy AI with purpose. That means we are not interested in technology for its own sake. We build products and workflows that help businesses operate better, serve users more effectively and achieve clear outcomes.

Role Description

We are looking for a QA Engineer to join QX on a contract, remote basis.

You will join an existing team of QA Engineers, but your remit will include helping to shape the QA function at QX.

This role is suited to someone who can take ownership of quality across AI-led applications and digital products. You will be expected to work at pace, adapt quickly, manage multiple priorities and contribute across the full testing lifecycle. This is a hands‑on role in a fast-moving environment, so you should be comfortable wearing multiple hats and working closely with developers, product stakeholders and delivery teams.

You will be responsible for ensuring the quality, reliability and usability of AI applications by designing and executing test cases, performing manual testing, using available automated testing tools and supporting quality assurance processes across product delivery.

Day to day, you will identify, document and report bugs, work with developers to investigate issues, validate fixes, support regression testing and help ensure that software meets defined requirements before release.

Key Responsibilities

• Own and execute quality assurance activities across AI-driven applications and related digital products
• Design, document and maintain clear test cases, test plans and test scenarios
• Carry out manual testing to identify defects, usability issues, edge cases and inconsistencies
• Use available automated tools to support testing, improve repeatability and increase QA efficiency
• Report bugs clearly, including steps to reproduce, expected results, actual results, severity and supporting evidence
• Work closely with developers, product stakeholders and delivery teams to investigate, prioritise and resolve issues
• Validate fixes and perform regression testing where required
• Review requirements, user stories and acceptance criteria to ensure expected software behaviour is testable and understood
• Maintain QA standards, processes and documentation
• Contribute to release readiness decisions by providing clear, evidence-based quality assessments
• Identify opportunities to improve product quality, testing coverage, user experience and internal QA processes.

Skills and Qualifications

• Strong understanding of quality assurance processes, software testing principles and QA best practice
• Proven experience designing and executing test cases based on requirements, user stories and acceptance criteria
• Experience with manual testing, defect identification, bug reporting and regression testing
• Ability to analyse software behaviour, identify issues and communicate findings clearly
• Strong analytical and problem-solving skills
• Excellent attention to detail and a structured approach to testing
• Clear written and verbal communication skills
• Ability to work independently in a remote environment
• Comfortable working in a fast-paced environment where priorities may change
• Ability to collaborate effectively with developers, product stakeholders and cross-functional teams
• Familiarity with testing tools, issue trackers and test management platforms
• Experience with automation testing or automated QA tools is beneficial
• Interest in AI applications, automation and emerging technology is a strong advantage

What We Are Looking For

• We are looking for someone practical, thorough and proactive. You should be able to take ownership of QA activity, challenge unclear requirements, spot risks early and help the team maintain a high standard of delivery.

The successful candidate will join a high-growth environment where initiative matters. This role offers broad exposure to modern AI product development and requires someone who can combine structured testing discipline with adaptability, curiosity and sound judgement.
