Product Designer

Every business is using AI. The ones that get it right start with real people. GWI is the human intelligence underneath: verified data that helps businesses understand what moves their audience, and act on it faster. If you want your work to matter, keep reading.

01What will I be doing?

As our Product Designer you’ll design how people and AI agents get to GWI data, working in a cross-functional squad alongside Product and Engineering.

Right now our biggest need is agentic, API and MCP. Customers reach GWI through agents, integrations and workflows as well as our platform, so you’ll shape the experiences built on our MCP servers and APIs: how a developer connects to an endpoint, how an agent calls a tool and gets a trustworthy answer, and how a person stays in control when it goes wrong. That’s where you’ll start, but there’s room to work in other squads and domains as our priorities change.

02A few things you’ll be responsible for

• Taking problems from discovery through to delivery, partnering with Product Managers, Engineers and Data teams.
• Designing the experiences around our MCP servers and APIs (onboarding, authentication, tool and endpoint discovery, error handling, usage and permissions) and improving the workflows that take developers, analysts and AI agents to trusted data.
• Designing for agents and machines as well as people, working with Engineering on tools, schemas, naming and error messages so the machine-facing and human-facing sides feel like one product.
• Using AI to speed up discovery, design and delivery, and prototyping with working code and live APIs so ideas get tested early.
• Contributing to our design system: proposing, designing and documenting components and patterns, including agentic and API-led ones, and working with Engineering to implement them consistently.
• Contributing to developer-facing content such as documentation, quickstarts and example flows.

Working at GWI means a high tempo environment where change is common. We’re building quickly because the industry is moving quickly, and our customers rely on us to stay ahead. If you like being part of that, you’ll enjoy it here.

03What do I need to bring with me?

You’ll need to be able to demonstrate the core skills this role requires. You don’t have to tick all the boxes right away; the important thing is that you’re willing to learn.

• Fluency with AI tools: you use them to prototype quickly, ideally against live APIs or in code, as well as to speed up research and design.
• Strong design system knowledge: you’ve built or extended components and patterns, written usage guidance, and helped keep a product consistent.
• Some experience with API or MCP workflows, or agentic products (or a strong appetite to learn fast), and an understanding of how APIs work (REST, authentication, rate limits, schemas, errors) and how they shape the experience.
• A solid product design and UX foundation, with a good grasp of interaction design and usability, and comfort in complex, technical product environments.
• Strong problem-solving and systems thinking: you break problems down, land on clear solutions, and see how a tool, an API response or an agent interaction fits into the wider journey.
• Clear communication with technical and non-technical stakeholders, and a collaborative, proactive approach that makes the team around you better.
• Independence within your squad, the judgement to seek input on the more ambiguous challenges, and the curiosity to pick things up quickly and adapt when priorities change.
• Proficiency with Figma, FigJam and Jira, and experience using qualitative and quantitative insights to inform decisions.

04Nice to have

• Experience designing developer tools, API documentation or developer portals.
• Hands-on experience building MCP servers.
• Experience with data products, analytics or market research platforms.
• Experience with a design system that covers non-visual patterns, such as API error messaging, agent interaction states or developer documentation.
• A track record of introducing a new process, tool or practice that your team adopted.
• Experience running lightweight research with technical users, such as developers and data analysts.

05Why Join Us?

• Work on a problem few teams have solved: designing how AI agents and developers get to trusted data through our MCP servers and APIs.
• Help set the patterns. You’ll shape how agentic and API-led experiences work at GWI and contribute to our design system, so your decisions carry across the product.
• Room to move. You’ll start in agentic, API and MCP, with the option to work in other squads and domains as our priorities change.
• A hybrid setup, with 2 days a week in our London office.

Weekly office requirement: 2 days Employment type: Permanent Seniority level: Intermediate to Senior

06Diversity, Equity & Inclusion 🫶

Diversity is fundamental to who we are-as a data company and as a workplace. Our data reflects global realities, and so must our teams. We strive to build a workforce as diverse and inclusive as the insights we deliver.
