Here at giffgaff we’re looking for a passionate and enthusiastic Software Engineer who doesn't just want to ship features, but wants to build the engine that ships them. 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. We work with many teams at giffgaff, including various partners and associates we rely on, to ensure we’re active and engaged with our engineering community, improving our ways of working and maintaining a high standard and quality of products we create.
What you’ll build & own
* Platform Architecture: Architect the core React Native framework, abstracting complex tasks into reusable components.
* 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.
Location: Our office is in Uxbridge, West London. Hybrid and remote options are also available.
