Our distinctive future is defined by our ownership;
Pell Frischmann is part of RSBG SE, the patient capital investment arm of RAG‑Stiftung.

RSBG SE’s mission is to generate sustainable funds for the foundation; our work directly contributes to fighting global pollution and climate change.

Pell Frischmann is seeking to appoint Seasonal Field Ecologists to join their Ecology team in the Luton office from March 2026 until November 2026 to assist with field work and reporting relating to bat surveying. Depending on workload at the time there could be potential to extend or an opportunity to transfer to permanent. Some experience of undertaking bat surveys in the field and desk‑based sound analysis is desirable, but not essential, as full training will be provided as part of the role.

The work will be primarily associated with a large scale infrastructure project in the Midlands but may also include occasional assistance to the wider ecology team on projects around the UK. As a result you must have your own transport and be able to work dawn and dusk surveys.

• Undertake a range of bat surveys, including use of thermal and infrared cameras and both handheld and automated detectors.
• Coordinate ecological survey arrangements, including logistics and access.
• Monitor site activities and liaise with the project team to ensure surveys are completed as scheduled and in line with project requirements.
• Analyze sound and video data gathered during the surveys.
• Provide report input for the bat surveys undertaken.
• Occasionally support the wider ecology team with desk‑based tasks such as report preparation and data searches.

Essential

• Under/postgraduate degree in Ecology, Environmental Management or a related discipline.
• Membership of the Chartered Institute of Ecology and Environmental Management (CIEEM).
• A current CSCS card or equivalent.

Preferred

• Some experience surveying a range of UK habitats and protected species (incl. but not limited to bats, badger, otter, water vole etc.).
• Previous experience of working within an engineering organisation.
• Relevant experience in a similar capacity as an Ecological Clerk of Works.

Skills

• Full UK driver’s licence.
• Ability to commute to Luton office and sites in the Aylesbury area regularly, or willingness to stay in accommodation (expensed).
• Good knowledge of relevant UK and EU wildlife legislation and of bat ecology.
• Proficient in bat sound analysis and competent in ecological surveying technology.
• Sound knowledge of environmental constraints and health & safety considerations.
• Excellent communication skills, able to convey ecological requirements to contractor teams.
