Product Engineer (Core)650709329274901227

Product Engineer (Core)

Location Barcelona Employment Type Full time Location Type Remote Department Engineering **Hello** 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 conversations become memory, ideas become action, and teams work with more clarity and speed. You’d be joining a team of \~20 people (previous Typeform, Revolut, Pitch, King, Skyscanner, etc.), 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 own, shape, and ship real products — not pitch decks. **About the role…** We're looking for a Product Engineer to build and evolve our core transcription and intelligence platform. You'll partner with Matej (Tech lead, ex\-Typeform), designers, and founders to ship features that serve both small teams and global enterprises. It's a role for experienced builders who love the craft — engineers who think in systems, care about impact, and know when to move fast and when to dig deep. **What you will do…** * Build and maintain the core HappyScribe app — the platform that hundreds of thousands of users rely on every month. You'll own features end\-to\-end, from idea to production. * Ship to learn. Proactively measure impact, seek user feedback, and iterate or kill features based on what you discover. * Collaborate with engineers, designers, and leadership to shape the product roadmap. You'll have a voice in what gets built and why. * Example projects: + Integrations with phone calling platforms to capture real\-time conversations. + Search and storage systems for insights across hundreds of transcripts. + Desktop app for local recording and seamless access to conversation data. **What you will bring…** * You're an experienced engineer who thrives in small, high\-output teams. You know how to balance speed with quality—and when to choose one over the other. * You're self\-driven and business\-aware. You care about solving real problems and moving the needle on metrics, not just shipping features. Give you context, and you'll find the leverage. * You communicate clearly with engineers and stakeholders. You can explain trade\-offs, own decisions, and stay calm when things are ambiguous. * You're comfortable with our stack (Rails, Turbo/Hotwire) or have solid experience in MVC\-based frameworks and can adapt quickly. * You're fluent in AI — you've built or integrated AI features, or you use coding agents regularly to work faster and smarter. * You're excited about our engineering principles, and most of the Rails doctrine aligns with your work style. **Bonus points if…** * You’ve worked in B2B SaaS products, not just agencies or consumer apps. * You’ve interfaced directly with customers — validating ideas, collecting feedback, or supporting launches. **Company Culture** A company culture built on trust, autonomy, and independence **️ We're remote\-first, office\-encouraged** — We work asynchronously and with high trust, but value in\-person collaboration for creativity and speed. * ️ **Flexible working hours** — Work on the schedule that makes you the happiest and productive. **Beautiful office in Gràcia** — One of the best areas in Barcelona. Our offices are much more than just a place to work. We like to see them alive 24/7, filled with friends and creative activities. Want to organise a community event, a breakfast with other designers, developers, etc.? The place is yours. . **International, English\-only speaking environment** — We're building an international team and want to create an inclusive environment where anyone can join any conversation at any time, even if it’s just kitchen talk. That's why you'll find Italian, French or Catalan people talking in English to each other. **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 vacation time** — To relax and recharge your batteries whenever you need to. **The hardware that you need to be most productive.** **Private Health Insurance** — We have partnered with Alan to best take care of our team both in Barcelona and while they’re on the road, covering half of the full price of the medical coverage. **Monthly savings** — Use part of your gross salary for meals, public transport, or nursery services through Cobee and enjoy income tax savings on everyday expenses.

Hands\-on experience creating or managing technical content is a strong plus. **Full\-funnel GTM experience** You have worked across awareness, evaluation, trial, and conversion flows and understand how narrative, content, product experience, and data all influence momentum through the funnel. **Pragmatism \& bias for action** You are comfortable operating in an early\-stage environment with evolving priorities. You make data\-informed decisions, move quickly, and balance “perfect” with “good enough” to drive meaningful progress. **GTM systems \& automation experience** You have worked with marketing automation, analytics, and CRM tools. You know how to build dashboards, implement conversion tracking, manage lead flows, and design processes for scale. **What You Will Do** ==================== **Own the whole GTM funnel \-** Design, implement, and continuously refine our GTM funnel from awareness evaluation free trial POC conversion. You will identify bottlenecks, conduct experiments, and develop the systems necessary to support efficient growth. **Manage and evolve our external\-facing assets \-** Oversee the website, blog, whitepapers, documentation touchpoints, and events.
