Senior Product Designer

About the role

You will own the discovery process for our billing and payments suite, planning and running user research to validate design decisions that move the business. You will define what is worth researching by framing questions and choosing methods that keep a continuous discovery cadence running alongside delivery. You will synthesize findings into actionable design opportunities and help shape the product roadmap with them. You will build and maintain a shared research repository so insights compound over time and stay accessible across the team. You will design intuitive, accessible, and aesthetically consistent interfaces for web applications that serve SMBs. You will own design work from low-fidelity wireframes to high-fidelity prototypes, ensuring pixel-perfect implementation that reflects our brand. You will partner with engineers during implementation to maintain design quality and fidelity through handoff. You will collaborate with Product Managers to define scope, requirements, and success metrics for features so that outcomes are clear. You will present design concepts, research findings, and rationale to stakeholders with clarity and confidence to align everyone on the vision.

• Familiarity with financial workflows, accounts payable, and accounts receivable processes will help you design with deeper context.
• Exposure to AI-assisted tools and prototyping workflows is valued as the product team explores AI-powered analytics and automation.
• Willingness to build and maintain shared artifacts like research repositories, design systems, and documentation that outlast individual projects.
• Commitment to evidence-based design, where decisions are grounded in user research, data, and experimentation rather than opinion.
• Ability to manage multiple streams of work and prioritize effectively across discovery, delivery, and strategic initiatives.

Nice to have

• Comfort turning ideas into working front-end prototypes, whether hand-coded or built with AI-assisted tools to validate concepts quickly.
• Fluency using AI as part of your process to accelerate exploration, generate and test concepts faster, support research synthesis, and cut the time between question and answer.
• Experience designing for B2B SaaS platforms or fintech products where security, compliance, and reliability are non-negotiable.
• Experience working with payment products or teams that handle money movement, settlements, and reconciliation.
• Knowledge of behavioral design or cognitive psychology principles to influence adoption and reduce friction in financial tasks.

Practical notes

This role is full-time and remote based in Brazil. There may be travel required for team offsites or stakeholder meetings, and occasional visa support may be needed for international collaboration. The schedule aligns with standard working hours, with flexibility for asynchronous communication across time zones. Deadlines are tied to product milestones, and the pace is fast as the team builds a platform that will scale globally.
