Senior Product Designer – Design Systems - London
London-Hybrid, 3 days onsite in London
No sponsorship available for this role
I'm partnering with a global, product-led B2B SaaS company operating at the intersection of data, infrastructure, and real-world impact. Their platform supports complex, high-stakes decision-making at scale, and as they continue to modernise and grow, design consistency, speed, and quality are becoming critical differentiators.
They’re now hiring a Senior Technical Product Designer-Design Systems to take full ownership of the design system underpinning their core platform and brand new SaaS product. This is an incredible opportunity to own a mission-critical design system at scale, shape not just the product, but how the product gets built, work on complex, meaningful problems with real-world impact and join a globally distributed, product-focused organisation investing heavily in design maturity.
The Opportunity
This is a high-impact, senior individual contributor role with true platform-level ownership.
You’ll be the single owner of the design system, responsible for defining its strategy, structure, and governance across a sophisticated, data-rich product environment. Operating outside of product squads, you’ll work horizontally across teams to ensure everything shipped is consistent, scalable, and production-ready.
Beyond the system itself, this role is about elevating how design happens, improving workflows, introducing smarter tooling (you must geek out over the latest AI tools), and accelerating the path from idea to implementation.
If you enjoy bringing order to complexity, influencing at scale, and shaping how world-class products are built, this is a rare opportunity to do exactly that.

Drive Consistency & Governance

Improve Design Velocity & Ways of Working

* Introduce modern approaches (including AI-enabled tooling) to reduce manual effort and increase speed
Bridge Design & Engineering
* Partner closely with engineers to ensure seamless translation from design to code
* Reduce gaps between design intent and implementation
* Contribute to scalable, reusable approaches across design and frontend
Influence & Enable Teams
* Guide Product Designers on best practices and system usage
* Provide clear rationale to align teams and drive adoption
* Raise the overall quality bar across the product ecosystem
