Senior Behavioural Designer — Behavioural Science Consultancy - London (Hybrid)
Our client is one of the UKs most respected behavioural science consultancies — recognised by the Financial Times for three consecutive years and trusted by major brands across financial services, retail, FMCG, travel and utilities to design interventions that measurably shift behaviour.
They work at a genuinely rare intersection: rigorous behavioural science, applied through high-quality design, at commercial scale. This isnt a team doing light BeSci decoration on top of standard UX. The behavioural thinking and the design craft are inseparable here.
Theyre looking for a Senior Behavioural Designer to join their London team.
The role
This isnt a production design seat. Youll be leading the application of behavioural design on client projects — translating research and BeSci insight into polished, commercially effective interventions across communications, UX, physical environments and service experiences.
Youll also be pushing how the team works: developing new approaches, contributing to proprietary neurodesign frameworks, and helping raise the bar for junior designers around you.
Day to day youll be:
* Owning key sections or full deliverables on client projects, from concept through to final output
* Applying behavioural science principles across multiple touchpoints and sectors
* Presenting and defending your work directly to clients, adapting your communication style to different audiences
* Contributing to proposals and supporting the commercial pipeline
* Mentoring and supporting junior team members
What were looking for
Youll have meaningful experience applying behavioural science frameworks within design work — not just awareness of BeSci, but genuine fluency in how it shapes decisions and how to make that tangible through design. Youre as comfortable in Figma as you are discussing cognitive load or choice architecture.
Specifically:
* A degree in Design, Psychology, Behavioural Science or a related field
* Proficiency in Figma and Adobe Creative Suite
* A strong portfolio of conceptually driven, behaviourally grounded work
* Proven client-facing experience — presenting, defending, building relationships
* Experience across varied touchpoints and sectors
* Curiosity about where behavioural design is heading — AI, motion, prototyping
Why this role
* Access to proprietary neurodesign frameworks and tools you wont find in most organisations
* A genuinely multidisciplinary team — behavioural scientists, designers and strategists — working on complex, high-profile briefs for major brands
* Real professional development, not just a line in a job spec
* A culture that takes the quality of its work seriously without taking itself too seriously
Our client is an equal opportunities employer. We welcome applications from candidates of all backgrounds.
