Join the growing London Design team at Tétris as a Senior Technical Designer. We're looking for someone with strong experience in workplace and retail design — a detail-focused, technical designer who thrives in a fast-paced Design & Build environment and is ready to step into a senior role within a global organisation.

You'll bring expert technical knowledge and strong communication skills, with the ability to translate creative vision into construction-ready packages that stand up on site.

You'll be actively involved in projects from concept through to construction issue, working closely with concept designers, estimators, project managers, and delivery teams.

• Review and sign off technical information
• Maintain Tétris technical standards across all project outputs

Innovation & Problem Solving

• Develop creative technical solutions that balance design ambition with practical delivery
• Stay up to date with materials, construction methods, and workplace design trends
• Contribute to continuous improvement of technical processes and standards
