We’re looking for an Ecologist to join our friendly and highly skilled team in Ashwell, Hertfordshire.
CSA Environmental is an independent, multidisciplinary consultancy of 85 people across five offices. Our Ashwell team of 14 ecologists form part of a wider team of 50+ ecologists across the business that have built a strong reputation for providing clear, reliable ecological advice, and for encouraging clients to go beyond standard expectations.
We are proud to hold the Great Place to Work certification (2026), independently awarded based on our team’s own feedback. It reflects what we’ve always believed: that good work comes from people who feel valued, trusted and supported to grow.
Ecology is not about compliance, it’s increasingly the discipline that shapes how development land is planned, designed and valued. At CSA, we take that seriously. We actively encourage clients to look beyond mandatory requirements and to think about what genuine long-term biodiversity improvement looks like on their sites. That ambition runs through our project work, our habitat bank schemes, and the advice we give at every project stage.

-
Undertaking UKHab baseline field surveys, with and without support/input from other ecologists in the team
-
Undertaking desktop data searches for biological records/information and discussions with nature conservation consultees, as required

-
Undertaking additional work outside of normal working hours, as reasonably required by specific survey needs and company workloads, on a par with the other ecologists (regular dusk and occasional dawn bat surveys, overnight newt surveys, etc.). At peak times this may involve 2–3 nights in a week (not including weekends)
-
Playing an active role in organising work and survey planning, to benefit the smooth running of the team
