The contract
Six-month contract, starting 5 January 2027. Outside IR35. Remote first, with some time on site. Why you'll want this
A lot of i OS contracts drop you into a client team on your own, picking up their ways of working while you try to deliver.
On this one you'll join a hedgehog lab team, working on a banking app customers use every day.
What's in it for you
You'll work alongside a Principal i OS Engineer and another Senior, so there's always someone to pair with or test your thinking.
You'll have room to do the work properly and fix problems at the source.
You'll have a say in where the app's architecture goes next.
With a 5th January start, you can line up your next contract before Christmas.
Who you'll be doing it for hedgehog lab is a digital product consultancy with 20 years of experience.
We're B Corp and Great Place to Work certified, with around 100 people working remote first across the UK.
This engagement is with a well-known UK bank, on its customer-facing i OS app.
Our team will be a Principal i OS Engineer, two Senior i OS Engineers, a Senior Android Engineer and two QAs.
What you'll be doing
Building features and refactoring in small steps, with tests protecting existing behaviour.
Writing unit tests, using dependency injection and mocking.
Handling sensitive data securely, from storage to networking.
Investigating defects and performance problems, including memory leaks, responsiveness and network behaviour.
Reviewing code and working closely with the bank's own mobile engineers.
What you'll need
Commercial i OS experience with Swift, and a sound grasp of core i OS frameworks.
Experience working within the architecture of a large, established codebase, using patterns such as MVVM, MVC or Clean Swift.
Unit testing experience, including mocking, dependency injection and asynchronous code.
Practical mobile security knowledge, including secure storage, secure networking and certificate pinning.
Confidence debugging memory, CPU and network issues.
It would help if you've worked on banking, fintech or other regulated apps, or brought Swift Concurrency or Swift UI into an existing app.
