Senior/Principal Occupational Hygienist | Expert Advisory & Expert Witness

Join Finch and Help Shape the Future of Occupational Hygiene.

At Finch, we work on some of the UK’s most technically challenging occupational hygiene projects.

We’re looking for an experienced Chartered Occupational Hygienist who combines technical excellence with sound professional judgement and passion for solving complex problems.

This is a rare opportunity to combine high-level consultancy work with a structure pathway into expert witness practice, supported by nationally recognised experts.

You’ll work on significant industrial and regulatory challenges, support litigation and forensic investigations, and develop the expertise required to become a trusted independent expert.

Whether your background is in consultancy, industry, or a regulatory environment, we'd like to hear from you.

The Opportunity

As a Senior/Principal Occupational Hygienist, you’ll lead complex consultancy assignments while developing specialist expertise in forensic investigations and expert witness work.

You’ll

• Lead occupational hygiene and exposure risk management projects across complex and highly regulated environments.
• Advise clients on the anticipation, recognition, evaluation, and control of workplace health risks.
• Support organisations facing regulatory scrutiny, civil claims, enforcement action, and legal disputes.
• Work alongside experienced expert witnesses, developing the skills needed to prepare expert reports and provide evidence in court.
• Influence senior leaders and boards, helping them make informed and defensible decisions.
• Contribute to thought leadership, technical innovation, publications, and service development.
• Help shape the future direction of occupational hygiene services within a growing consultancy.
• What Success Looks Like

You’ll be recognised as a trusted technical adviser whose expertise is valued by clients, colleagues, and regulators.

You’ll confidently translate complex occupational health risks into practical, evidence-based solutions and build a reputation as an independent authority within the profession.

Over time, you’ll develop the capability and credibility to provide expert opinion in legal proceedings and establish yourself as a recognised expert in your field.

What We're Looking For

We’re interested in professionals who combine strong technical capability with curiosity, integrity, and excellent communication skills.

• Chartered Occupational Hygienist status (or close to achieving chartership).
• Significant occupational hygiene experience within complex industrial, operational, or highly regulated environments.
• Strong understanding of exposure science, occupational disease prevention, and UK health and safety legislation.
• Experience influencing senior stakeholders and decision-makers.
• Excellent written and verbal communication skills.
• Strong analytical ability and evidence-based professional judgement.
• An investigative mindset and a genuine interest in forensic and expert witness work.
