Company Overview

At Ecology by Design, we’re redefining what it means to be an ecological consultant — blending scientific rigour with creativity, innovation, and a genuine commitment to restoring nature. Here, your expertise isn’t boxed in by bureaucracy or lost in endless process. It drives real-world change.

Culture & Values

We prioritise the health and well-being of our staff. From encouraging people to take appropriate leave throughout projects and having in‑house mental health support, keeping our team safe, healthy and feeling valued are all part of our culture. While quality and timeliness of surveying and reporting is core to our business, we like to have fun too. If you’re an ecologist looking to progress your career and make a tangible difference — whether stepping into senior responsibility or leading projects at a principal level — we’d love to hear from you.

If you’re a Senior or Principal Ecologist ready to take ownership of your work, influence project outcomes, and lead with purpose, this is your moment. You’ll join a passionate, forward‑thinking team where autonomy, trust and technical excellence go hand in hand — and where your ideas shape landscapes, policy, and the next generation of ecological practice.

Why Join Ecology by Design

We’re not your typical corporate consultancy — and that’s exactly the point. 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.

We believe happy, trusted people do their best work — so we give you the freedom to shape how you work, not just what you do. 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 an SME with a genuinely awesome team 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. And if you’re someone who loves to explore new ideas — whether experimenting with AI, testing new methodologies, or even building a new business from scratch — you’ll have our full support. Our trust‑first policy means we back innovation, not bureaucracy.
