About this role
HELLO ✨ We’re HappyScribe https://www.happyscribe.com/, a profitable, 100% bootstrapped AI company based in Barcelona. We built one of the web’s most accurate multilingual transcription platforms, trusted by hundreds of thousands of users each month. That product funds our freedom to create what’s next—no investors, no burn rate, just focus. Now we’re taking that same tech and expertise to a bigger frontier: turning conversations into intelligence. We’re building the layer where speech becomes memory, insights become action, and teams work with more clarity and speed. You’d be joining a team of ~17 people, close-knit and pragmatic. Some of us are scaling a mature, revenue-generating platform. Others are prototyping new products that push the limits of speech and agentic AI. We move fast but think long-term. There’s room here to shape, ship, and own real products — not pitch decks. ABOUT THE ROLE: You’ll join the Engagement pod, which owns our web app, and our mobile and desktop recording apps. You’ll work in a small team with Matej, Eduard and a designer, and report to Ignasi, our CPTO. You’ll own a product area from day one. WHAT YOU’LL DO - Own Engagement features end to end, across our Rails backend and our React web, React Native mobile and Electron desktop apps - Decide with your designer what to build, then prototype it, ship it with coding agents, and prove it works with evidence - Grow our design system and component library together with the designer - Make architecture calls across the stack, review other people’s work and raise the pod’s bar WHAT WE’RE LOOKING FOR - You’ve been full-stack in production. You’ve shipped both backend and frontend code that real users rely on - You’re AI-first. You use coding agents every day, and they write all of your code - You build things in your own time. Big or small, we want to see it - You’ve shipped at least one cross-platform mobile or desktop app - You’ve worked on a design system or component library - You have product judgment. You can partner with a designer and prototype without waiting for mockups or a PM - You’re comfortable with ambiguity and get moving without full specs - You check quality with evidence, not by reviewing every line - 5+ years of experience and fluent English Nice to have, but you can learn it here: Ruby on Rails (solid experience in another server-side framework is fine), and whichever of mobile or desktop you haven’t done yet. COMPANY CULTURE - 🤝 A company culture built on trust, autonomy, and independence - 🤲 Hybrid set-up - Our setup is hybrid and built on trust. We come together in our Barcelona office for the things that are better in person, and protect focus time wherever you work best. - ⏱️ Flexible working hours — Work on the schedule that makes you the happiest and productive.

Your space for collaboration and community. - 🌏 International & English-fluent — Global team, fully inclusive conversations. WHAT WE OFFER... - 💰 Competitive salary — our salaries are in the top percentiles of the Barcelona startup scene. - 📈 Equity — By joining the company when the team is so small, you’re helping us set the foundations of our future success. We're asking you to come on an adventure, so if we find a treasure, we want you to get a piece. - 🤖 Generous token spend policy — We expect our team members to work at the frontier of what's possible with AI. We expect spending, not saving, at the moment - 🏖️ 30 days holiday allowance — Recharge whenever you need to. - 🍏 Health coverage — Alan https://alan.com/es-es partnership covers half your medical insurance, anywhere you are. - 💳 Tax-smart savings — Cobee by Pluxee https://www.pluxee.es/productos/ for meals, transport, nursery. Keep more of what you earn.
