PolyAI serves hundreds of enterprises across 75 languages and 25 countries, including Metro Bank, Marriott, PG&E, and Uni Credit.

We're hiring a senior brand designer to own PolyAI's visual identity and to build the AI-native systems that let that identity scale. You are the day-to-day owner of how the brand looks and feels across campaigns, web assets, sales, events and video. You are also a design engineer  turn recurring design work into templates, automations and AI-assisted workflows, so the team can produce on-brand work faster without losing craft.

You will work with the Creative Director, the web and content teams, marketing, sales and product. This is a hands‑on role with real ownership and a lot of range. One week you may be directing a launch video, the next you may be building a component library or an automated asset pipeline.

• Own and manage the brand identity across all marketing: website, events, advertising, sales materials, video and audio demos.
• Champion consistency across the company, including sales, product and people teams. Say no when it matters, explain why and offer a better option.
• Evolve the identity as the company grows, and document it so others can apply it correctly.
• Design web assets, including landing page visuals, page graphics and animation, and hand them to the web team and partners to build. This role does not build pages.

• Build and maintain a living brand design system: tokens, Figma libraries with variables and components, templates, and guidelines written for humans and for AI tools.
• Turn repeatable work into AI-assisted workflows, templates and generators that marketing, sales and product can use without a designer in the room.
• Automate production with scripts, AI coding tools and no-code tools, for example resizing and localising ad variants, generating decks and building video templates.
• Define quality guardrails for AI-assisted output: review checkpoints, acceptance criteria and feedback loops that prevent brand drift.
• Evaluate and adopt new AI design, image, video and audio tools. Share what works and what doesn't, and help the wider team build fluency.

• Concept and design campaign assets end to end: key visuals, paid and social creative, ebooks, one-pagers, sales decks, event materials and custom client content.
• Direct and produce video and motion work, from storyboard to final edit, using both traditional tools and AI-assisted workflows.
• Use design thinking to solve marketing problems, and work with the team to test and improve engagement and conversion.
• Repurpose content across channels.

• Partner with design, motion, and development partners or agencies end to end: briefs, direction, review and quality.
• Partner with engineering and product so the brand carries through to product-adjacent surfaces.
• Explain design decisions to non-designers and tie them to business goals.

• 7+ years of brand design experience, with a track record of owning a brand or identity at an applied AI, SaaS or other fast-growing technology company.
• A portfolio showing a brand system that grew and was applied consistently across channels. Case studies of tools, templates or workflows you built are a strong plus.
• Hands-on experience using AI tools in real creative workflows (generative image, video, audio and layout tools), with a clear view…
