Validation Engineer

Summary of the role

A Validation Engineer is a technical expert responsible for proving that equipment, processes, and systems consistently produce a product that meets its predetermined specifications. They are the “proof providers” of the quality system. Their work is a non-negotiable part of regulatory compliance, as regulatory bodies like the MHRA require a validated manufacturing process to ensure patient safety and product quality. The role is highly detail-oriented and requires a strong understanding of both the technical aspects of manufacturing and the regulatory framework that governs it.

Typical Duties

The duties of a Validation Engineer are a mix of project management, technical documentation, and hands-on testing:

• Protocol Writing and Execution: A core duty is to write detailed validation protocols, such as Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ). You’ll then execute these protocols to gather data that proves the equipment or process works as intended.
• Master Validation Plan Development: You’ll contribute to or develop a Master Validation Plan, which is the high-level strategy for how an entire facility or a specific project will be validated.
• Computer System Validation (CSV): In today’s digital world, a key part of the role is to validate computer systems and software used in manufacturing and quality control, ensuring they are compliant with regulations like 21 CFR Part 11 (for electronic records and signatures).
• Change Control: You will be responsible for assessing the validation impact of any proposed change to an equipment, process, or system. You’ll ensure that any changes are properly documented, tested, and validated before they are implemented.
• Regulatory Compliance: You’ll be a key person during regulatory audits and inspections, providing documentation and technical expertise to prove that your company’s processes are compliant.
• Cross-functional Collaboration: You’ll work closely with a wide range of teams, including Manufacturing, Quality Assurance, Facilities/Maintenance, and R&D, to ensure a smooth and compliant validation process.

While the core principles are the same for advanced therapies and broader life sciences, the specific focus changes:

Advanced Therapies: The work would be centred on the validation of cleanrooms, single-use technologies, and specialised equipment for cell and gene therapies. You would be focused on maintaining the integrity of highly sensitive, often personalised, biological materials.

Wider Life Sciences: You might be working with a broader range of products, from large-scale protein production to vaccine manufacturing. The engineering challenges might be more focused on managing large-scale industrial equipment, automation, and optimising process yields.

Key Skills and Qualifications (UK)

Essential Qualifications: A Bachelor’s or Master’s degree in a relevant engineering discipline (e.g., Chemical Engineering, Mechanical Engineering) or a scientific field (e.g., Biotechnology, Biochemistry) is almost always required.

Essential Certifications: A deep and practical understanding of Good Manufacturing Practice (GMP) is crucial. Many companies look for candidates who have formal training in validation principles and regulations like the EU GMP Annex 15. Achieving Chartered Engineer (CEng) status is highly desirable for career progression.

Essential Skills:

• Technical Expertise: A strong understanding of manufacturing equipment and processes.
• Attention to Detail: Meticulousness is non-negotiable, as all documentation must be perfect and all test results accurate.
• Problem-Solving: The ability to logically diagnose and solve complex problems during the validation process.
• Communication: Excellent technical writing skills for creating clear and concise protocols and reports are essential.

Salary Expectations (UK)

Starting Salary: For an entry-level Validation Engineer in the UK, a starting salary is typically in the range of £30,000 – £40,000 per year.

After 3-4 Years: With a few years of experience and a strong track record of successful projects, a Validation Engineer can expect to earn between £45,000 – £60,000 or more. Progression to Senior Validation Engineer or management roles can lead to even higher salaries.
