Senior QA Engineer

Vesynta

Vesynta is an investor-backed precision medicine company based within the London Cancer Hub. We are building clinical decision support software that personalises dosing of critical therapies at the point of care which provide clinicians with access to data-backed pharmacology models; resulting in fewer toxic side effects, and significantly improved treatment efficacy. We exist to support patients (children, but also women and those with diverse ethnic heritages) who have been traditionally under-represented and poorly served by traditional, coarse dosing methodologies. Our team is fast-paced, results-oriented, and mission-driven.

The Job

Drive the quality and reliability of impactful healthcare solutions as our QA Engineer. You will be passionate about delivering high-quality software through hands-on end-to-end UI automation and API testing. Working closely with developers, product managers, and DevOps engineers, you will ensure every release meets our rigorous standards for performance and usability.

You will:

• Design, develop, and maintain automated test scripts using Playwright for web applications
• Create and execute Postman collections and integrate them into CI/CD pipelines using Newman
• Perform manual and exploratory testing to ensure full coverage
• Collaborate with developers to identify, document, and resolve defects and performance issues
• Implement test strategies across UI, API, and integration levels
• Set up and maintain automated test pipelines (CI/CD) using tools such as Jenkins, GitHub Actions, or GitLab CI
• Generate and analyze test reports, metrics, and dashboards to communicate quality progress
• Contribute to improving QA best practices, frameworks, and tools
  
  

A full role specification will be supplied to candidates as part of the application process.

The Products

Our web, mobile and Electronic Health Record-integrated applications offer best-in-class actionable precision dosing insights to healthcare professionals, supporting the end-to-end process of Therapeutic Drug Monitoring and Model Informed Precision Dosing. With these, the primary users (hospital-based clinicians, pharmacists and nurses) are able to provide patients with enhanced and personalised care across several therapeutic areas including antibiotics, chemotherapeutics and immunosuppressants.
