Senior Freshwater Macroinvertebrate Laboratory Scientist in Letchworth Garden City

Are you passionate about freshwater ecology and the vital role aquatic invertebrates play in understanding environmental health? Do you have a sharp eye for detail, strong taxonomic skills, and the drive to deliver scientific excellence?

APEM are looking for a Senior Freshwater Macroinvertebrate Laboratory Scientist to join our expert team at one of our laboratories in Stockport, Edinburgh, or Letchworth. Our analysts are at the forefront of environmental monitoring—supporting projects for water companies, regulators, and consultancies, from drought permits and pollution assessments to invasive species monitoring.

In this role, you will analyse and identify macroinvertebrate samples to APEM's industry-leading standards, ensuring accuracy, consistency, and efficiency in all analyses. You will contribute to high-profile environmental monitoring projects, supervise and support junior staff, and continue developing your own expertise—potentially specialising in specific taxonomic groups. You will also have opportunities to get involved in fieldwork, data reporting, and the preparation of tenders and technical documentation.

To be successful in this role, you will need:

• At least 5 years' experience identifying freshwater macroinvertebrates from a range of UK habitats
• An excellent AQC record and ability to work to tight deadlines
• A strong understanding of aquatic ecology and the UK water industry
• The ability to manage workloads effectively and maintain high-quality standards
• An understanding of other types of aquatic biological analysis (e.g. phytoplankton, zooplankton, diatoms)

What helps you stand out:

• Experience identifying macroinvertebrates to mixed taxon/species level
• Specialist knowledge in specific macroinvertebrate groups (e.g. damselflies, dragonflies, INNS species)
• Experience in live bankside analysis or training junior staff
• Understanding of Water Framework Directive methodologies
• Experience contributing to business cases or tenders

At APEM, our people are our greatest asset. We value integrity, quality, collaboration, and forward thinking, and we are committed to providing an inclusive, flexible workplace where everyone belongs.
