• Champion good design and help shape the culture and ambition of our growing architecture team
• Grow into a leadership role — with the opportunity to shape team culture, support junior colleagues, and take on more responsibility over time

What we’re looking for:

• A natural team player with an ambition to grow into a leadership role as someone who’s ready to take ownership and develop long-term client relationships with the support of the wider leadership team
• RIBA Part III qualified or international equivalent; ARB registration preferred
• 5+ years’ post-registration experience within a respected design consultancy
• Proven experience across all RIBA stages , with design leadership and technical delivery capability
