Frontend developer for web conversion

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.

• 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.
• 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.

• Grow a reusable component library so new pages ship in days, not weeks.

• You have 3+ years of frontend experience with React / Next.js and modern CSS.
• You have a real eye for UI: spacing, hierarchy, states and micro-interactions.
• You work mobile-first by default, not as an afterthought
• You are comfortable working from Figma, side by side with designers, and you can challenge a choice with data and alternatives.
• You have worked on CRO, A/B testing or conversion-driven web projects.
• You are data-driven: you think in conversion rate, drop-off, page speed and funnel, and you act on what you see.
• You are AI-native: AI is already part of how you prototype, test and ship.
• Fluent Italian or Spanish and professional English.
• Будет плюсом: TypeScript is a plus; startup or high-growth experience; GA4, GTM or PostHog; technical SEO; headless CMS such as Strapi; no-code tools; motion and animation

• Gross salary 35.000-40.000 €, based on experience
• 1.000 € fringe benefit, 1.000 € welfare and 8 € a day in meal vouchers
• a critical growth area that is yours, not someone else's backlog
• every test you ship moves a number the whole company looks at
• the more you move the needle, the faster you grow
• An offsite every 6 months with the whole team
• a team that celebrates wins together, gives honest feedback and has fun along the way.
