We are Callstack, a React & React Native consultancy trusted by global tech leaders. Founded in 2016, we have grown into a 200-person, remote-first company that helps companies build scalable apps, solve architectural challenges, and contribute back to the tools they use every day. We move fast, ship with purpose, and value people as much as code.
You’ve definitely heard of our clients, including companies like PwC, DIRECTV, Major League Soccer, Evernote, and Amazon. What makes these partnerships work isn’t just code or business relations. We offer strategic input, product insight, and operational support that help their teams ship smarter, scale faster, and stay focused on what matters. From global brands to early-stage ventures, we collaborate like part of the team, because that’s exactly what we are.
We take growth seriously, and that includes yours. You’ll have access to a personal development budget, ongoing feedback, and the freedom to try new things. Whether you’re building in sales, marketing, project management, or finance, you’ll have ownership from day one, support when it matters, and the kind of impact you can actually see.
You might have heard of React Universe Conf: a conference we created to allow the brightest minds in the community to push the boundaries of what’s possible with React and React Native. That’s just one part of how we show up. We write blog posts, run podcasts, and contribute to Open Source; not to market ourselves, but to move the ecosystem forward. We share what we learn and invite others to build with us.
Regardless of the contract, you will get the same benefits as everyone else! That means flexible hours, paid time off, sick leave, and access to mental health resources. We also support your growth and well-being with our personal budget and real tools to do great things.
