Extraction Chemist

Purpose And Scope Of The Role

This full-time, permanent Extraction Chemist position is based at Tetra Tech’s Bedford laboratory. You will carry out routine extractions, sample preparation and instrument support within a commercial analytical team serving water, utilities, agrochemical and defence clients. Daily activities include performing extractions to established quality procedures, maintaining consumables and bench equipment, and contributing to calibration and equipment checks. You will work in a laboratory that has an international reputation for resolving complex analytical challenges and was among the first in the UK to gain UKAS accreditation for PFAS analysis.

Project work ranges from short monitoring campaigns to multi-stage remediation programmes; you will collaborate with analysts, chemists and technicians across the laboratory team to deliver timely, regulatory-compliant results. The role forms part of an Extraction Development scheme, with regular performance reviews that support salary progression.

In the short term you will ensure consistent, high-quality sample processing and support routine reporting. Over the medium term you will contribute to method optimisation and support larger remediation and monitoring projects, increasing your technical autonomy. Long term, the role provides a clear path to senior analyst or method development positions within the laboratory, with opportunities to lead client programmes and specialise in PFAS or pesticide residue work on significant, multidisciplinary projects.

• Technical laboratory practice:
  Competent execution of extraction and sample preparation techniques, accurate use of pipettes, balances and standard bench equipment.
• Quality and compliance:
  Understanding and application of QC/QA procedures, record keeping and adherence to UKAS‑style accreditation requirements.
• Time and task management:
  Ability to prioritise variable workflows, meet turnaround targets and adapt to changing project demands.
• Team collaboration and communication:
  Effective liaison with colleagues and clients, clear written and verbal reports and readiness to seek guidance when needed.
• Safety and risk awareness:
  Safe handling of chemicals, solvents and potentially biohazardous samples; adherence to COSHH and laboratory safety protocols.

Degree in Chemistry or closely related subject (graduate level), practical laboratory experience, attention to detail and basic calibration skills. Desirable: UKAS/accredited laboratory exposure, and formal training in laboratory quality systems.

Based in Bedford, laboratory-based role with five days on site. Standard working pattern is Monday - Friday, 14:00 - 22:00
