The role

We’re looking for a senior Product Designer (~5 YoE) to join Sequence and help shape the future of AI-powered finance automation. As one of our first designers, you’ll work closely with product, engineering, and founders to design intuitive, AI-native workflows for billing, invoicing, and receivables.

You’ll thrive here if you love operating in ambiguity, exploring new interaction models, and making AI agents feel both powerful and trustworthy.

You’ll be part of a small, high-leverage team where your design decisions have immediate product and customer impact.

What you’ll do

• Design AI-first product experiences across billing, invoicing, collections, and finance agent workflows

• Partner with PMs and engineers from discovery through shipping to bring new concepts to life

• Explore how agentic AI workflows should behave. What they do automatically, when they ask for input, how they explain their reasoning

• Move fluidly between broad concepts and tactical deliverables: from sketching a new finance copilot experience to refining a critical interaction for invoice approval

• Prototype rapidly, testing ideas with internal stakeholders and customers

• Contribute to design reviews and help build a strong design culture at Sequence

This may be a good fit if

• You’ve shipped B2B products, ideally in finance, b2b or workflow-heavy domains

• You’re comfortable in an early-stage environment and excited to help shape both product and process

• You’re interested in AI tools (such as Cursor, Midjourney, Figma Make, Claude Artifacts, etc.) and curious about designing with and for AI

• You embrace ambiguity and enjoy exploring entirely new interaction patterns rather than refining existing ones

• You prioritize speed and impact over weeks of analysis & research

This might not be a good fit if

• You want to spend most of your time running long-form user research studies or maintaining large design systems

• You prefer highly structured environments with detailed requirements

• You’re not interested in AI or unfamiliar with designing for AI-native workflows
