Job description

Location: London, UK (Office-based)

Company: Fyxer AI

Revenue Goal: $100M+ by EOY 2026

The Mission

At Fyxer AI, we believe the only sustainable competitive advantage for a startup is the quality and speed of execution. You aren't starting from a blank page. We’ve recently partnered with Red Antler to redefine our visual identity, and we are now looking for a Senior Product Designer to take that vision, build upon it with us and scale it across our entire product ecosystem.

You’ll be working alongside another product designer and working closely with the Founder CPO and Founder CTO.

While not day 1, we are still very early in our mission to make Fyxer’s platform legendary for the thoughtful and clean experience you’ve come to admire from the world's very best apps.

A Designer’s Dream: The Product

We don't build boring CRUD apps. You will be designing high-utility, complex interfaces that feel like magic:

• The Notetaker: A sophisticated real-time interface that generates live transcripts and insights.

• Customisable Drafts: A feature that generates deeply personalized AI responses based on user context.

• The Ecosystem: A seamless journey across web and mobile web that turns raw AI power into an intuitive daily habit.

Who You Are

• Evidence-Led: You have a strong affinity for User Research. You don't just move pixels; you run your own research, gather insights, and use them to defend your design decisions.

• Startup Veteran: 6+ years of experience in high-growth environments (Series A–D, 20–120 employees).

• System Thinker: You won't be designing from scratch. You’ll use our existing design system to maintain consistency while proactively evolving it as we scale.

• Technically Fluent: You understand the "how." You are comfortable working with a stack of Figma, ShadCN, Tailwind CSS, and Lucide.

• High Intensity: You thrive on speed. You believe every minute counts and that execution is a competitive sport.

The Role

• Execute & Iterate: Take our world-class brand identity and apply it to complex product flows, ensuring every interaction feels premium and trustworthy.

• User-Centric Ownership: Own the research process for your features. Talk to users, identify friction, and prototype solutions that solve real problems.

• Collaborative Building: Partner directly with Product Engineers. We have no PMs; you will be the bridge between user needs and technical implementation.

• Maintain Excellence: Ensure the "Instant Usability" of our web app, design system, and mobile web experience stays at the highest level.

Our Stack

• Design: Figma, Miro, Lucide

• Tech Alignment: ShadCN, Tailwind CSS, V0 (for prototyping)

• Insights: Posthog (Surveys, Session Recording, Analytics)

Why Fyxer AI?

We are intentional about our team. We believe a small, exceptional team working with extreme focus will always outperform a large, bloated organization.

• Autonomy: We hire people who want ownership and then we actually give it to them.

• Velocity: You will be fast-tracked into senior responsibilities far earlier than at a traditional company.

• Scale: We are on track to hit $100M in revenue by the end of 2026. This is a rare opportunity to join a high-growth rocket ship at the foundational stage.
