You will join our Platform Team with a clear mission: Enable our feature teams to move faster, safely. You will own the mobile architecture, the design system, and the developer experience. You won't just write code; you will design the standards for security, performance, and scalability that the rest of engineering relies on. You will work in a cross‑functional team with like‑minded people to ensure this product is successful and sustainable.

- Design System Ownership: Build, document, and maintain the core UI library to ensure UI consistency across iOS and Android.
- Mobile DevOps: Own the CI/CD pipelines and manage the release lifecycle, including iOS/Android beta testing and upgrades.
The must haves:
- 5+ years of software engineering experience, with deep expertise in React Native.
- Proficiency in TypeScript and a strong understanding of static typing.
- Experience writing or maintaining Native Modules (Swift/Obj-C or Kotlin/Java).
The other stuff we are looking for:
- Observability, “you build it you run it” attitude.
- Event‑Driven Architecture; SOLID principles; micro‑frontends.
- Deep knowledge of performance profiling (Flipper, Xcode Instruments).
- Background in creating CLI tools to automate developer workflows.
Benefits: We offer a competitive salary and a comprehensive benefits package, including hybrid working options and a supportive, inclusive culture. Employees are encouraged to enjoy a healthy work‑life balance and are supported with various perks and development opportunities.
