Why Join Ecology by Design

We’re an independent, people‑first ecology business built on trust, flexibility, and creativity. Forget timesheets, clock‑watching, and rigid hierarchies. Here, you manage your own hours, work where you work best, and take unlimited holidays when you need them.

Our offices are dog‑friendly, relaxed, and full of energy. You’ll be surrounded by passionate ecologists who care deeply about their work and each other. We’re a small‑to‑mid‑size team with a genuinely awesome culture – from summer Olympics and Three Peaks challenges to Friday drinks and spontaneous adventures, there’s always something happening if you want to get involved.

We’re proud to be diverse and inclusive, with team members from all backgrounds – LGBTQ+, neurodivergent, and from a wide mix of cultures and experiences. We see diversity as our collective superpower, and we’ll help you use yours to the max.

• Excellent communication and organisational skills, with the ability to work independently and as part of a team.
• A full UK driving licence and willingness to travel as required.
• Experience in EcIA, BNG, BREEAM, or related ecological assessments.
• Experience of mentoring or line management (particularly for Principal‑level candidates).

• CIEEM membership (or eligibility).
• Degree (or equivalent) in an ecology‑related discipline.
• Advanced or multiple species licences (e.g. Bat Low Impact, Badger).

We maintain a healthy, team‑orientated, supportive culture. Communication is key to all that we do, both with clients and across the company.

We prioritise the health and well‑being of our staff. From encouraging people to take appropriate leave throughout projects to in‑house mental health support, keeping our team safe, healthy and feeling valued are all part of our company ethos. Whilst quality and timeliness of surveying and reporting is core to our business, we like to have fun too.
