Founding Backend Engineer
Intro Corporation
Join Our Team at IntroIntro is growing our team of amazing people who are on a mission to give everyone access to anyone, empowering each other to create a better world. Intro started in 2022 by first building a tool for the world's top founders and experts, enabling their audiences from all over the world to be able to access them, jump on a live video call, and get personalized advice. We were (and still are) grateful to see that it was an INSTANT hit.Today, we have over 20k five star reviews, and the founders of Reddit, Zillow, Sweetgreen, DryBar, and 1k+ more all became partners, as well as advocates of our product, company, and mission. We then launched a marketplace, chat, subscriptions, and more, each leading to faster growth.We're just getting started — the Intro of tomorrow will look very different than the Intro of today. In fact, we're confident that Intro will become the go-to network for access, knowledge, and…(we can't say the last part just yet), all over the world.If you're interested in joining an amazing company that is growing (fast), loved by its users, and deeply cares about quality, we'd love to meet you.TeamHey everyone! it's Raad, CEO at Intro.Our team is world-class. It's the best team I've ever worked with because everyone here is (1) a good person who cares about the mission (2) they're functionally great at their craft, and (3) they help each other out! It's a very no-drama type of place which is what happens when everyone is really good at what they do.In their past careers, people on our team helped create or build major products like QuickBooks Online, Uber Eats, Calm, and more. We love working on BIG problems for a LOT of people and believe that Intro will be the most impactful yet.Role OverviewWe are looking for a Senior/Staff level Backend Engineer to design, build, and maintain scalable backend systems that power our product.
