Founding Product Designer

About Us

annwn is building a new category of product: an AI-native platform for sustainability professionals and enterprise.

We give consultants and enterprises specialist AI agents, structured tools for complex knowledge work, and a digital twin of the organisation so people can work with far better context, clarity, and speed. The goal is better decisions, better delivery, and better outcomes for business and the world.

This is AI for a better world. The work matters. The customers matter. The product has the potential to shape how sustainability work gets done across large organisations.

The Role

We’re hiring a founding product designer to help define that category.

You’ll work closely with the Founders / CPO and engineering to design the core experience of the platform: agent-driven workflows, human review and refinement, data-rich interfaces, and the systems that make a powerful product feel clear and trustworthy.

We’re looking for someone who is not just a strong designer, but an AI-native builder. Someone who uses AI fluently as part of how they think, design, prototype, and ship. Someone who can move from concept to flow to prototype quickly, work closely with engineers, and help invent new interaction patterns for how expert users work with agents.

This is a ground-floor role with real influence over the product, design culture, and customer experience.

What you’ll do

• Design the product end to end, from early concepts through to production-ready designs
• Shape the core UX for agents, workflows, review flows, decision support, and expert user tooling — in such a way that our product is intuitive and relevant for our customers
• Help define new interaction patterns for AI-native work, including delegation, oversight, refinement, and trust
• Turn complex sustainability and enterprise workflows into interfaces that feel clear, useful, and fast
• Prototype ideas quickly in Figma (or similar) and, where useful, in code or AI-assisted tools
• Help define the product’s structure, navigation, and design system
• Work closely across the team, clearly articulating and engaging in debate around the design direction of our platform
• Speak to users regularly and turn insight into better product decisions

What We’re Looking For

We are looking for a positive, collaborative, curious designer who loves tackling knotty problems. Someone who enjoys learning and applying new knowledge, and who values team contribution.

Research shows that women and people from under-represented groups often only apply to roles when they meet 100% of the criteria. Please don’t let that stop you — if you meet most of the skills below and are excited about the mission, we’d genuinely love to hear from you. We strongly encourage applications even if you don’t meet every single requirement: we value potential, leadership, and transferable experience, and we’re actively working to build a diverse founding team.

Core skills

• 5+ years of product design experience, ideally in complex B2B or expert-facing software
• Strong experience designing workflow-heavy, data-rich products
• Excellent product thinking, interaction design, and information architecture
• High level of visual craft and attention to detail
• Ability to make dense workflows and complex systems feel simple and coherent
• Confidence working closely with engineers in an early-stage environment
• Comfort with ambiguity, pace, and shaping a product as it is being built
• Strong fluency with AI tools as part of your design and build workflow
• Clear evidence that you can prototype, test, and iterate quickly — not just hand over polished mock-ups

Highly desirable

• Strong judgment on designing for AI-native products, including trust, visibility, uncertainty, and human-in-the-loop review
• Experience with AI products, or strong judgment on how AI changes UX
• Enterprise SaaS experience
• Data visualisation experience
• Front-end development experience
• Familiarity with sustainability, climate, or regulatory domains
