Product UX/UI Designer

Valencia, Spain

We’re looking for a Product UX/UI Designer to help TraceAir ship better product decisions faster.

This role is for a designer who loves the full cycle: Task framing → research & hypotheses → quick prototypes → validation → production-ready UI → post-launch iteration.

You’ll work closely with Product Managers, Engineers, Marketing, and Customer Service to evolve existing flows and launch new features and products, using research and metrics to turn uncertainty into clarity.

What you’ll do

• Frame problems like a detective: Dig into user behavior, support tickets, recordings, funnel drop-offs, and edge cases to find what’s actually broken (or missing).
  Mixpanel / Hotjar investigation and analytics experience is a big advantage — if you have case studies, please send.

• Generate and validate hypotheses: Propose solution directions, prototype quickly, and run lightweight research/testing to reduce risk before dev investment.

• Design end-to-end flows: From low-fi exploration to production-ready UI with strong interaction details.

• Work in a design system: Use components, variables, and libraries; enhance the system when gaps emerge; maintain consistency without slowing down.

• Partner closely with PM and Engineering: Clarify scope, align on trade-offs, define acceptance criteria and Definition of Done, and keep delivery moving.

• Communicate clearly: Present reasoning, decisions, and alternatives — not just screens.

• Keep documentation tidy: We are a mature company, so maintaining organized records is essential. Status reports and ticket descriptions in Asana aren't just bureaucratic tasks; they're vital for keeping us sane and efficient. We’re seeking someone detail-oriented enough to keep up with it.

What we’re looking for

• 3–5 years of product design experience (web apps preferred; B2B SaaS is a plus)

• Strong skills in UX thinking + UI craft (flows, states, error handling, edge cases)

• Practical experience with research and validation: usability tests, interviews, surveys, and analysis of recordings

• Comfort with product metrics: conversion, retention proxies, event thinking

• Confident Figma skills (component architecture, variants & variables, library management, prototyping)

• Experience working with design systems and contributing to their evolution

• Autonomous and proactive: you don’t need to be chased; you chase clarity

• Strong collaboration and stakeholder communication: you can negotiate, align, and move work forward without drama

• Ability to analyze and unravel complex flows and mechanics, and investigate missing information (engineering/tech background is a plus)

• English: solid working proficiency (async collaboration, reviews, documentation)

You’ll be a great fit if you…

• Enjoy moving fast without breaking the product

• Love ambiguity and can turn “we should improve onboarding” into a concrete plan with measurable outcomes

• Naturally notice inconsistencies, missing states, weird edge cases, and “silent” UX failure points

• Can balance craft with pragmatism: when to go deep vs when to ship

What you’ll work on (examples)

• Improving onboarding/activation and feature adoption using funnels + session insights

• Launching new product capabilities with rapid validation and tight delivery cycles

• Evolving key workflows and reducing friction across the product

• Strengthening the design system to enable the team to ship faster and more consistently — negotiating and prioritizing resources, delivering designs, and overseeing execution

What we’ll ask in the hiring process

• Portfolio with 2–3 case studies showing your thinking (problem → research → options → validation → outcome)

• Ability to explain tradeoffs and how you used research or data to make decisions

• Examples of close collaboration with PM/engineering and shipped outcomes
