Finary

What is Finary? Our mission is to change how money can work for you. We're building the one-stop shop for investing, where you can track your assets, manage your budget, invest, and learn, giving power back to investors. Mounir launched Finary in 2021, and we've since crossed 1,000,000 users. We ship cutting-edge products with touches of delight, and we care deeply about experience, performance, and ease of use. Why now? A new generation of investors is emerging: ambitious and involved. Money is no longer taboo, and the pension system is under tremendous pressure. We see a world where investing empowers everybody to live the life they've always dreamt of. To fuel that, we raised a €25M Series B in September 2025, backed by PayPal Ventures, Hedosophia, Y Combinator, and Speedinvest, alongside world-class founders and operators like Steve Anavi & Alexandre Prot (Qonto), Matthieu Rouif (Photoroom), Eric Demuth (Bitpanda), Axel Weber (former UBS Chairman), and Harsh Sinha (CTO at Wise). And in July 2026, the AMF granted us our MiCA license, on top of our Investment Firm license: Finary is now one of the very few French platforms holding both, offering stocks, ETFs and crypto on a single regulated platform, at the exact moment Europe consolidates around licensed players. There's never been a more exciting time to join. What we offer We hire people who lift the team's ceiling: A-players who are as kind as they are demanding. We move fast, aim high, and treat ownership as the default. Our culture is direct, transparent, and built on radical candor. We challenge each other openly, then commit. It's demanding and not for everyone, but if you want to raise the bar every day alongside equally driven teammates, this is the place. And we don't hedge on this. We believe AI fluency is the single most important skill of the next decade, and it's a real bar here, not a buzzword. Everyone at Finary has rebuilt how they work around AI. It's the first reflex, not a side experiment. If reaching for AI before you reach for the old way isn't already second nature, this won't be the right fit. If it is, you'll be surrounded by people pushing that frontier every day. Read more about our values here. What you can expect * A high-performing team: work with A-players across every discipline, in an environment that challenges you and helps you grow fast. * Ownership from day one: freedom, responsibility, and trust. We hire for talent and get out of the way. * Impact that matters: build a product that helps people take control of their financial future. * A hybrid setup: teammates across France and Europe, meeting in person in Paris six times a year. * Competitive compensation: a package aligned with your experience and impact. What we don't care about * Your degree or your school. We care about what you bring to the team. * Ping pong tables, free laundry, or trendy perks. We focus on what truly matters. At Finary, we're on a mission to give power back to investors. We've grown to 1M+ users on the strength of our product, and we're now making a defining bet: becoming an AI-native company in the next 6 months, in how we build and in what we ship. As VP Engineering, your mission is to lead that transformation and own engineering end-to-end.
