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 Most tools in this space are complex, outdated, and built for admins, not for the people who actually use them every day.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.
