Product Designer
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. They integrate into the existing ERP, no migrations required. SOC 2 Type II and GDPR compliant, with clients in Spain, the UK, and France.
About the Role
This is the first internal designer. There's no design system in place, no established design structure — you build it. The product combines data-dense interfaces (reconciliation tables, accounting entries, close dashboards) with AI-driven conversational flows. You'll work closely with engineering and the founders, and you'll need to defend design decisions with product context, not just aesthetic instinct.
Responsibilities
Own product design end-to-end — from definition through handoff to engineering.
Build the design system from scratch.
Design interfaces for complex financial workflows: invoice processing, bank reconciliation, period-end close management.
Work alongside the engineering team during implementation and ensure design fidelity in production.
Participate in client conversations to validate design decisions with real users.
Contribute to the visual direction of the product as it evolves toward a more conversational AI model.
Requirements
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.
Startup experience or genuine appetite for that pace.
Use of AI tools in your workflow is a plus.
Expectations
Ownership without waiting for everything to be defined.
Judgment to prioritize between urgent and important.
Direct collaboration with engineering, no friction.
Willingness to iterate fast and kill your own work when context demands it.
Why Join
First internal designer — the visual language of the product is yours to define.
Direct impact on a product used by finance teams at companies across Europe.
Work directly with the founders from day one, no intermediaries.
Competitive USD salary and equity.
If you want to build something that matters for finance teams in Europe and own the design craft from the ground up, this is the role.
