Job description
Our mobile apps are how tens of thousands of entrepreneurs run their business and how their customers experience digital products. We ship white-label apps across iOS and Android using Flutter, with a fully automated CI/CD pipeline via Codemagic. The work matters and the scale is real: 150+ white-label apps, each serving a seller and their customer base., * Own mobile features end-to-end: understand the problem, build the solution, ship it, and make sure it works for real users on real devices.
- Build and maintain Flutter apps for iOS and Android, keeping a single codebase clean and performant.
- Work with shared API endpoints alongside the web frontend team, understanding how backend changes affect the apps.
- Improve and maintain the white-label app infrastructure so onboarding new sellers is smooth and reliable.
- Keep the CI/CD pipeline (Codemagic) healthy and the release process to both app stores fully automated.
- Collaborate with designers, product managers, and backend engineers to figure out what to build and why.
- Integrate AI-powered capabilities into the mobile experience where they create real value.
Requirements
Do you have experience in iOS?, Enthusiastic drivers. You fully own your projects and get them done. You know when to ask for help. "Are we there yet?" is the wrong question.
Optimistic problem solvers. Things get hard sometimes: tricky platform differences, store review rejections, features that touch multiple teams. You won't get disheartened. You'll collaborate, iterate, and ship your way through it.
Grown ups. We're an international bunch, and one thing unites us: everyone is kind, considerate, and professional. This isn't about age or experience. It's about being low-ego, flexible, and respectful.
Genuine builders. People who love building software and would still be doing it without a paycheck. If that sounds like you, we should talk.
