Principal Product Designer - Agentic Workflows

Principal Product Designer: AI & Agentic Workflows

Remote-first in the UK.

The company

We’re partnering with a 250-person SaaS scale-up that has rebuilt its product around AI. Its agent is already live with customers and AI is now the company’s core product strategy - not an additional feature.

The role

Reporting directly to the VP of Product, the Principal Product Designer will become the design counterpart to the engineering architect - defining how agentic workflows and traditional SaaS interfaces come together as one coherent product.

This is a hands‑on player–coach role with the influence of an early‑stage design leader, backed by the customers and resources of an established scale‑up. You’ll set the design direction, support a team of five designers and personally lead the hardest product challenges.

You'll

• Define the interaction architecture and design patterns across the product
• Design the most complex experiences yourself, prototyping and shipping in code (Claude Code, Cursor)
• Lead critique and raise the bar for a team of five designers
• Partner with Product, Engineering and leadership on direction

You've

• Spent 10+ years in product design, including several operating at Staff or Principal level
• Designed complex AI products at a top‑tier SaaS company
• Shipped genuinely agentic workflows - not just standalone AI features
• Set design direction across an entire product, beyond your own product area
• They have a very high bar and have never lost out on exceptional talent because of salary constraints, so this won’t be a blocker.
