About the Company
They build the accounting engine for modern finance teams. Their platform learns each company's accounting logic — chart of accounts, business rules, dimensions — and uses AI to automate work that's still manual today: processing invoices, reconciling bank accounts, and managing period-end close.

4+ years of product design experience.
Portfolio that demonstrates visual judgment and product thinking — not just polished screens, but design decisions grounded in business context.
Experience with SaaS or fintech products with high information density interfaces.
Ability to operate as the sole designer in a small team with no prior structure.
Figma proficiency.
Fluent conversational English.
