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.
• •Design or configure interfaces, workflows, recipes, data models and environments, including site serialisation system integrations, and write or review related specifications and test scripts. Hold configurations, interface mappings and scripts under version control, subject changes to peer review, and verify them through repeatable automated or scripted tests, retaining traceable test evidence under approved change and GxP validation controls.
• •Own the technical reliability of site serialisation systems, including monitoring, recoverability, obsolescence and technical debt, addressing root causes so that incidents do not recur rather than closing individual tickets
• •Actively extract and codify existing serialisation knowledge into runbooks, integration patterns, troubleshooting guides and technical documentation, building capability across the wider engineering teams rather than creating a single point of dependency.
• •Lead technical design and implementation across multiple projects, releases or sites.
• •Review and approve key technical specifications, design documents, configurations, test scripts and validation evidence.
• •Lead diagnosis and resolution of complex incidents, integration failures and data-integrity issues, and act as the technical authority over strategic partner output – accepting or rejecting designs, configurations and test evidence against GSK engineering, architecture and regulatory standards.
• •Assess technical risks and ensure mitigation addresses security, compliance, resilience, data integrity and supportability.
• •Maintain technical standards and reusable engineering assets for the assigned product family or platform.
• •Support formal technical assurance, GxP validation, audits and inspections for regulated site systems and ensure corrective actions are evidence based.
• •Identify repetitive serialisation engineering and support activities suitable for automation, reduce manual diagnosis, testing, deployment and support effort, and reuse automation across sites rather than resolving the same problem repeatedly.
• •Apply AI-assisted methods to development, troubleshooting, testing, documentation and automation within Responsible AI, data privacy, cyber security and GxP controls, validating all output before use and retaining human accountability for technical decisions.
• •Direct and coordinate external vendors, system integrators and managed service partners across design, build, release and stabilisation; set technical direction and acceptance criteria for their work, review and formally accept or reject their designs, configurations and test evidence, and hold them to GSK engineering, architecture, security and GxP standards.
