Requirements

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

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.

Pay & benefits

What you'll get

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 partnership covers half your medical insurance, anywhere you are.
💳 Tax-smart savings - Cobee by Pluxee for meals, transport, nursery. Keep more of what you earn.

The role

We're HappyScribe, 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.

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
