Overview

Neutreeno is hiring its first full-time UX Designer to own the end-to-end design of a complex emissions data platform. The problems are genuinely hard: emissions data is messy, deeply hierarchical, and full of uncertainty. Users span operations, finance, and sustainability teams inside some of the largest companies in the world, each with different mental models. Your job is to make that complexity feel obvious and to make the resulting insight something a decision-maker acts on.

This is a hands-on, founding role with a path to leading an expanded design function as the company grows. The position is hybrid with a minimum of 2 days per week in the Cambridge office.

Product Design

• •Own end-to-end design from problem framing and information architecture through to interaction detail and shipped UI.
• •Make complex, uncertain, hierarchical emissions data legible and actionable for operations, finance, and sustainability audiences.
• •Set the visual and interaction direction and raise the bar on craft across everything shipped.
• •Prototype fast and often.

Design System, Built AI-First

• •Define, build, and maintain the Neutreeno design system: foundations, components, patterns, content, and data-visualisation standards.
• •Architect the system to be machine-readable and AI-native so AI coding tools and agentic workflows can build against it reliably.
• •Make the system the fastest path to both a prototype and production UI.
• •Champion AI-native design and development practices across the team.

Cross-Functional Collaboration

• •Work shoulder-to-shoulder with software engineers, translating design intent into well-scoped work that ships reliably.
• •Partner with the Head of Product on discovery, roadmap, and prioritisation.
• •Work with climate engineers to understand the methodology behind the numbers and represent uncertainty, assumptions, and data quality honestly in the interface.

Customer Engagement and Research

• •Design and run structures that make client engagement continuous and systematic: design partner programmes, regular usability sessions, feedback channels, and a clear route from what is heard to what is built.
• •Embed those structures across the company so engagement is a shared habit rather than a design activity.
• •Run discovery research on new product capabilities: what to build, for whom, and what good looks like.
• •Measure whether shipped work moved the needle and feed that back into the roadmap.

Minimum Qualifications

• •7 or more years of professional product or UX design experience, with a portfolio you can talk through in depth.
• •Proven experience designing complex B2B, enterprise, or data-heavy products.
• •Demonstrable experience defining and running a design system, including how engineering consumes it.
• •Strong craft across research, information architecture, interaction design, and visual design.
• •Real, daily use of AI tools as a core part of how you work, whether for prototyping, design system tooling, research synthesis, or generating production-ready UI.
• •Experience running research and usability sessions directly with customers and turning what you learn into decisions.
• •A track record of shipping high-quality work at pace, with high autonomy and little process.
• •Strong communication and the ability to build trust quickly across engineering, product, science, and leadership.

Preferred Qualifications

• •Experience as an early or founding designer at an early-stage startup.
• •Comfort working in and around code: enough to read a component, ship a small front-end change, or hold a credible conversation about implementation trade-offs.
• •Experience designing data visualisation for analytical products, including communicating uncertainty.
• •Experience building AI-powered product features or designing for agentic and LLM-driven interfaces.
• •Exposure to climate, sustainability, supply chain, manufacturing, or deep-tech domains.

Compensation and Benefits

• •Competitive pay dependent on skills, qualifications, and experience.
• •25 days annual leave.
• •Year-end performance bonus.
• •Meaningful equity stake.
• •Company pension with NEST.
• •Leading private health insurance with WPA.
• •Cycle to work scheme.
• •Remote working allowance of 2 weeks per year for personal travel in addition to regular holiday.
• •Hybrid work model based at Neutreeno HQ at the Cambridge Institute for Sustainability Leadership.
