We don't follow best practices, we set them
We build and scale React and React Native products with expert engineers and AI agents. If you enjoy solving engineering problems and taking responsibility for what you build, you’ll fit right in.








Open positions
Join us to build products and improve how teams deliver software with AI agents.
A place for builders, learners, and leaders
We build products across platforms and work on architecture, performance, and native integrations. We also develop tools and workflows for agentic software delivery. If you value ownership and sharing what you learn, you’ll feel at home here.
We always play to win
We lead the market by delivering the highest performance and exceptional value, setting ambitious goals and taking ownership to achieve them.
Drive for personal growth
We take responsibility for our growth and success by owning our professional development, seeking feedback to improve, and prioritizing our well-being.
Build positive relationships
We prioritize respect, understanding, and care for those around us by treating each other with respect, actively listening, and showing empathy.
Innovate for future success
We shape the future by embracing the unknown, actively seeking and experimenting with new ideas while sharing the lessons we learn.

Not your average software company
Work with React Native contributors and open-source tool builders on product development and agentic delivery projects that stretch your skills. Collaborate with teammates who share knowledge and own what they ship. And that’s only the beginning of a long list of perks of working at Callstack.

Remote-first by design
Work from wherever you do your best work. Our team spans 10+ countries, and remote is the default, not a perk. Some roles may require hybrid or in-office work, but unless it’s in the job description, you won’t be asked to return just because.

Workations and team events worth showing up for
From team-wide workations to internal meetups, we make space for deep work, real connection, and a little adventure. Each Callstacker gets a one-week workation in a villa somewhere in southern Europe.

Wellbeing & Development Budget
Use this flexible budget to invest in your growth, learning, and overall well-being, from courses to physiotherapy.

We’ve got your back, at work and beyond
Fully covered life insurance
We care about your future, which includes support for you and your family when it matters most.
Time off that actually supports you
You get 24 paid days off per year, plus up to 30 days of paid sick leave. No games, no stress-we want you to rest when you need to.
Private healthcare
We co-finance private healthcare plans for you and your family or provide an equivalent if you're outside Poland.

Whether it’s a Multisport card or local equivalent, we help cover the cost of staying active.
