Senior Software Engineer; Mobile Platform

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.

• 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 Dev Ops:
  Own the CI/CD pipelines and manage the release lifecycle, including iOS/Android beta testing and upgrades.

Do you want to join a connectivity provider that's up to good? At giffgaff, we do things differently. We call out the bad and find a better way. We're laser-focused on flexibility, value and mutual good.

In return for your outstanding efforts, you'll be rewarded with a competitive salary and excellent benefits that are all about making your work life a winner. Take a look at our culture and benefits - you might just be surprised.

Our bright and modern gaff is in Uxbridge, in leafy West London. But if commuting isn't for you, most of our roles can be hybrid or remote, or anywhere in between.

In order to be considered, you must have the following experience;

• 5+ years of software engineering experience, with deep expertise in React Native.
• Proficiency in Type Script and a strong understanding of static typing.
• Experience writing or maintaining Native Modules (Swift/Obj-C or Kotlin/Java).

We'd also love you to bring;

• 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.

Our goal is to celebrate our people and their lives. We aim to create a culture that empowers everyone to bring the best versions of themselves to work each and every day. We believe the most inclusive and diverse culture makes for a better business and a brighter world.

Working at giffgaff means you get a bumper reward package bursting with benefits, and loads of extras you can add if you'd like. These are designed to support both you and your loved ones, making sure that you're covered no matter what life throws your way.

We're all about hybrid working here, so expect to have a base location where you'll have the right facilities to enable amazing collaboration and quality time with your team, alongside all the right kit to work from home too.
