About You
Responsibilities
- Developing strategy — zooming out to see the bigger picture, identifying interaction design opportunities and navigating ambiguity to shape product strategy aligned with long‑term goals

- Testing assumptions — generating multiple ideas, establishing metrics to measure success and guiding the team to respond to evidence‑based insights
- Creating prototypes — using technical knowledge in the right level of details (paper, clickable, or code) and testing ideas with users to influence decision‑making
- Designing for accessibility — leading inclusive design from start to finish across discovery, alpha, and beta, and implementing comprehensive accessibility testing plans
- Establishing design patterns — auditing designs for consistency, effectively using existing design systems, reducing complexity and technical debt
- Working with developers — bridging the gap from user needs to tech implementation, communicating design intent clearly to translate designs into working software
- Communicating design decisions — telling the compelling story of our work and impact, and consistently presenting yourself in a confident and effective manner in complex project environments
- Elevating capabilities — actively mentoring others, providing proactive and actionable feedback, fostering an inclusive team culture
- Driving practice growth — actively sharing knowledge with wider audiences and strategically managing your time to deliver value while supporting bid, proposals, or pitches

- Apply digital accessibility principles and standards (WCAG) across all stages, implementing testing plans that use assistive technologies (JAWS, VoiceOver, Magnifier, and Dragon)
- Audit designs for consistency, differentiate between patterns and components, and contribute to complex design systems (GOV.UK, NHS, etc)
- Demonstrate the value of prototyping in code, using tools like GOV.UK and NHS prototype kits
