Job Purpose The Principal Tech Engineer – Site Serialisation Systems provides technical leadership for site serialisation systems within PIMMS (the Manufacturing Track & Trace product), across the broader product family, technology platform or programme. The role leads solution design, validation, implementation and troubleshooting and ensures technical outputs align with approved architecture, product strategy, engineering standards and GxP requirements. The role is hands-on and embedded close to business problems. The job holder personally investigates complex failures, interrogates data, logs and interfaces, challenges vendor and partner designs and resolves integration problems, rather than primarily coordinating or escalating them. The role works across the site serialisation estate rather than being tied to a single site and retains technical judgement and engineering integrity where strategic partners deliver routine build, test, deployment and support. The job holder applies AI-assisted methods to development, troubleshooting, testing, documentation, knowledge management, monitoring and automation, while retaining full human accountability for technical decisions and GxP, Responsible AI, cyber security and architecture compliance. The role also develops engineering capability by coaching engineers and super users and converting lessons learned into reusable designs, standards, training and knowledge. Key Responsibilities Implement technical solution designs and configurations in accordance with approved architecture and product strategy. Own technical quality for the assigned scope, including specifications, design documentation, configuration records and technical validation evidence. Perform troubleshooting and root-cause analysis, with timely escalation where manufacturing batches, product quality, patient supply or data integrity may be affected.
