Senior Product Designer (B2B)

💼 About Valeria Valeria is building the future of HR and payroll in Spain. We're an AI-native platform that automates contracts, payroll, and compliance for companies with high employee turnover (hospitality, delivery, events, agriculture). We're rethinking how an entire industry works—moving from manual, error-prone processes to intelligent automation. We're a fast-growing startup backed by top investors, disrupting a €5B+ industry that's still stuck in spreadsheets and legacy software.

🤝 Your Role

HR software has a UX problem. Most tools in this space are complex, outdated, and built for admins, not for the people who actually use them every day. We're fixing that. You will be defining AI-powered workflows that make payroll feel effortless.

You'll report to the CPO and work across the full product, both the core HR/payroll platform and the AI experience layer.

What you’ll do

We are looking for a Product Designer with technical skills and AI fluency to join our team.

The old way is over, but the design process isn’t. The traditional wireframe → mockup → handoff model no longer fits how great products are built today. We’re looking for someone who uses AI as a core part of their workflow, from rapid prototyping and research synthesis to design and implementation support.

Your job

•

Work closely with the CPO, engineering and AI, shipping features that are both beautifully crafted and technically robust.

•

Use AI tools (Cursor, v0, Claude Code, Codex) to design and prototype without waiting on engineering

•

Ship fast, gather feedback, and adjust

•

Shape how AI surfaces in the product: when it acts, when it asks, and when it stays out of the way

•

Share ownership of the design system together with the engineering team: challenge it, propose new components, and think actively about how design decisions can compress development cycles

•

Lead user research — interviews, usability tests, concept validation — and turn findings into sharp design decisions

•

Own the end-to-end design process from discovery to production-ready specs

•

You’re comfortable moving between Figma, Claude Code, and AI tools to turn ideas into reality, faster.

Must-have

•

4+ years of experience in product design b2b, with a strong UX foundation (not just UI)

•

Strong technical foundation — Understand how AI systems are built well enough to design intelligently on top of them, and actively think about how design decisions impact development velocity

•

A portfolio that shows complex problem-solving — ideally in B2B, SaaS, or data-heavy products

•

Experience designing for or alongside AI features (conversational UI, copilots, agentic workflows)

•

Strong research instincts — you validate before you build

Nice-to-have

•

Background in HR tech, fintech, or other regulated/complex domains

•

Experience setting up a design system from scratch

Mindset

•

Systems thinker with a bias for action.

•

Comfortable operating in ambiguity and moving fast.

•

Highly autonomous: sees what needs to be built and makes it happen.

•

Obsesses over understanding users and developing exceptional product intuition.

•

AI-native by default: willing to challenge established processes and adopt better ways of working.

•

Clear, concise communicator in both Spanish and English.
