[Milan or Barcelona based]
Pillar was founded in 2025. Today, we are 90+ people, serve 1000+ customers, raised €15.2M (pre-seed and seed round) and are expanding internationally.
We are building the financial operating system for construction: bringing AI, automation and modern software to an enormous industry still full of slow, fragmented processes.
We are looking for a Frontend Engineer who thinks about the person on the other side of the screen, loves a measurable result and wants to build the web experience behind Pillar's growth.

Why join now
Growth at Pillar can no longer be only sales-driven: we are building a scalable, measurable acquisition engine. Most of our traffic is mobile, and most of it never reaches a form. Every point of conversion rate we gain is a point we don't have to buy in paid media. We need someone who owns that problem at the interface level: layout, interaction, speed and clarity.

The mission
Make every page easier to use and easier to say yes to: own the UX, speed and conversion of our acquisition paths, from the first landing page to the onboarding wizard.





What you will do within the Growth Team
• 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 our 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.

Who we are looking for
• You have 3+ years of frontend experience with React / Next.js and modern CSS. TypeScript is a plus.
• You have a real eye for UI: spacing, hierarchy, states and
