We're excited to be supporting a large-scale NHS pathology transformation programme and are looking for multiple experienced LIMS Testers to join a major implementation across four NHS Trusts.
This is a fantastic opportunity to join a high-profile programme delivering a new Laboratory Information Management System (LIMS) across multiple pathology laboratories simultaneously. Due to the scale of the implementation, we're looking for experienced testers who can hit the ground running and support the end-to-end testing lifecycle.
Working closely with programme stakeholders, laboratory SMEs, and the wider project team, you'll be responsible for ensuring the solution is thoroughly tested, defects are effectively managed, and all testing documentation is completed to a high standard.
