About Bunch

Every adult loses hundreds of hours a year to admin. Bills they're overpaying. Renewals they forgot. Forms half-filled on a Sunday night. None of it is hard. All of it is exactly the kind of work AI was built for. We're building the AI that handles it. All of it. So people never have to think about it again. We're Series A, moving fast, and we intend to build something that becomes part of how the world works.

We're a small team building from scratch, and we're looking for exceptional people who want real ownership of what they create. If you want to see the direct impact of your work and be part of the founding team that defines how this gets built, read on.

The Role

As Product Designer, you'll shape how people experience the product, from first click to lasting habit. You'll own the full arc of design, from raw research through shipped experiences and have real influence on product direction. As the first designer in the team you will translate new brand guidelines into our product for the first time and be responsible for shaping and developing them as we grow.

You'll design how people interact with an AI that handles their money, their contracts, and their time - where every word, screen, and interaction either builds or erodes trust. You'll shape conversational flows for our AI assistant, craft microcopy that feels warm and precise, and prototype rapidly with AI-native tools before opening Figma.

You'll work in a small, cross-functional team alongside Product Marketing, Engineering, Growth, Brand and Customer Experience. This is an environment where your work ships, your opinions land, and your craft will grow.

What You'll Do

Lead end-to-end UX and UI for one or more core product areas, from discovery through delivery

Produce journey maps, service blueprints, flows, wireframes, prototypes, and high-fidelity specs as the moment demands

Optimise customer journeys based on data analysis and feedback loops

Collaborate closely with engineers during build, staying close to ensure intent survives implementation

Define and track UX metrics that connect design decisions to real user outcomes

Contribute to and evolve the design system; raise the quality bar for the whole team

Design conversational, text-driven interfaces where language is the product and every word matters

Prototype rapidly using AI-native tools (v0, Cursor, Lovable, Replit) to validate ideas before committing to code

Build trust mechanics into every touchpoint with transparency about what the AI is doing, why, and what it means for the user

Run hypothesis-led experiments, designing for measurable proof, not just polish

Simplify genuinely complex decisions (energy tariffs, broadband packages, council tax) into flows that feel effortless

QA what ships, you care as much about the live experience as the Figma file

Who You Are

We care far more about how you think than where you've been. That said, you'll likely have:

AI-first approach to delivery and always looking for new AI tools to optimise productivity and execution

5+ years in UX / product design

Portfolio showing complex problem-solving, not just beautiful screens

Mastery of Figma (or similar tooling)

Strong research & synthesis skills

Experience shipping at scale

Comfort with data and experimentation

Clear, confident communication

A point of view and the humility to update it

A natural feel for conversational and text-driven interfaces - you treat tone, hierarchy and word choice as design decisions

Comfort prototyping with AI-native tools - you reach for v0 or Cursor as naturally as Figma

Strong facilitation instincts - you bring clarity when engineers, PMs and stakeholders are circling a problem

High personal bar for quality - sloppy details, inconsistent patterns and lazy defaults bother you

Bonus Points

Experience with design systems at scale

Motion / interaction design chops

Background in SaaS, fintech, or marketplace

Familiarity with front-end code (HTML/CSS)

Experience with consumer advocacy, compliance, or trust/safety design

Understanding of B2B2C distribution, you’ll be designing for partner-embedded experiences as well as our direct B2C app

Experience designing for products people trust with their money
