Description

A fast-growing startup building a financial operating system for construction is hiring a Frontend Developer for its Growth Team, based in Milan or Barcelona. The mission is to own the UX, speed and conversion of acquisition paths from the first landing page to the onboarding wizard. The role combines shipping pages and components, running A/B tests with marketing, and keeping the site fast, accessible and mobile-first.

Responsibilities

Build and ship pages, components and flows with a strong focus on conversion and performance
Turn Figma designs into polished, mobile-first interfaces and speak up when a design won't convert
Own the UX of conversion paths: landing pages, forms, onboarding wizard and navigation
Run A/B tests with Marketing and iterate on layout, copy placement and interaction patterns
Use session recordings, heatmaps and funnel data to find where people drop off, then fix it
Keep the site fast and solid: Core Web Vitals, responsive behaviour, accessibility and SEO-friendly markup
Grow a reusable component library so new pages ship in days, not weeks

Requirements

3+ years of frontend experience with React / Next.js and modern CSS
TypeScript is a plus
A real eye for UI: spacing, hierarchy, states and micro-interactions
Mobile-first work by default, not as an afterthought
Comfort working from Figma side by side with designers, challenging a choice with data and alternatives
Experience with CRO, A/B testing or conversion-driven web projects
Data-driven mindset thinking in conversion rate, drop-off, page speed and funnel
AI-native approach with AI already part of how you prototype, test and ship
Fluent Italian or Spanish and professional English

Conditions

Full-time employment
Based in Milan or Barcelona or open to relocation
Gross salary 35 000–40 000 € based on experience
1 000 € fringe benefit, 1 000 € welfare and 8 € a day in meal vouchers
Real ownership of a critical growth area
Impact you can measure: every test you ship moves a number the whole company watches
Growth based on impact: the more you move the needle, the faster you grow
An offsite every 6 months with the whole team
