Senior Product Designer

Winnin; Brasil; Presencial; BRL 180 000 - 300 000; Tempo integral

Resumo da oferta

Winnin is building an AI-first product organization and seeks a senior designer to own usability and UX across our web and mobile platforms. You will partner with Product and Engineering to decide what gets built, not just how it looks, and you will set the bar for design excellence in a fast-paced environment.

You will craft prototypes quickly, evolve our design system, and design for dense workflows under real-time pressure with accessibility in mind.

Qualificações

• Experience designing dense, workflow-heavy platforms.
• Ability to turn user insights into working prototypes quickly.
• Ownership of design systems and contribution to product strategy.

Responsabilidades

• Understand the operation and its economics well enough to challenge a requirement, not just receive it.
• Run your own discovery with users and internal operators, and turn what you hear into problem definitions the team agrees on.
• Move from problem to clickable prototype in days, not sprints, using AI tools as your default way of working.
• Ship functional prototypes with real data and real logic that can be tested end to end.
• Design AI-native experiences: conversational interfaces, agentic workflows, human-in-the-loop review, model uncertainty, and failure states.
• Own and evolve our design system across products: tokens, components, documentation, adoption.
• Design for the hard states (empty, loading, error, offline, edge cases) and guarantee accessibility across web and mobile.
• Define what metric your work should move before design starts, and follow it after launch.
• Mentor designers, run critique, and defend decisions to leadership with user evidence and business reasoning.
• Bring new tooling and better ways of working into the team.

About Us

Trucking moves the American economy. It is a $1 trillion market, and it still runs on fragmented operations, thin margins, and technology a generation behind. Billor, short for "Bill of Rights,", is the only company transforming this market end to end, combining Freight and Technology for Truck Drivers, Freight Brokers, and Small Carriers into a single ecosystem. We operate a fleet of several hundred heavy-duty trucks and run integrated business lines across freight, fintech, and technology platforms.

About the role

We are building an AI-first product organization, and that changes what design means here.We are not looking for someone to hand off screens. We want a designer who takes a messy business problem, talks to the people living it, and comes back days later with a working prototype others can click and break. Someone who builds instead of describes. You will own usability and UX across our product portfolio: dense, workflow-heavy platforms used by people under real time pressure, where every second of friction has a measurable cost. Web and mobile, internal and customer-facing. You will be the most senior design voice in the room. You set the bar, own the design system, and sit next to Product and Engineering as a partner in deciding what gets built, not just how it looks.
