mustard is a creative recruitment consultancy and is committed to fostering an inclusive and diverse workplace. We encourage individuals of all backgrounds, experiences, and perspectives to apply. Our recruitment process is free from discrimination and bias and we welcome the opportunity to work with you. If you require any accommodations during the application process, please let us know. We appreciate the unique skills and experiences each candidate brings, and we are dedicated to creating an environment where everyone feels valued and respected.

As a Mobile focused Engineer, you will primarily be working on our Android and/or iOS apps, although you'll be open to dabbling elsewhere in the stack. You could also be working on the architecture design for some of our exciting new features, perhaps around DevOps, maybe streamlining some of our AI work and deciding how that should be displayed to the user.

Skills / Experience 🤹🏽

(Almost) nothing here is a hard requirement, clearly the more the better but we certainly don't expect you to have it all:

• 6+ years programming experience / 4+ years with loads of relevant mobile experience

• UK-based

• Built responsive, real-time mobile apps from scratch that aren't just CRUD - we're making some exciting things, and they need to be slick. Give us an example if at all possible!

• Kotlin/Android or Swift/iOS experience (the more the better) - both is even better

• Designed and worked on large systems with lots of moving parts and uptime requirements

• Professional experience with some of DevOps, AI/ML, VoIP, Infosec.

• Demonstrated ability to pick up new stuff quickly.

• Be comfortable working on the backend to either unblock yourself with quick fixes or build small features (with the potential to spend more time on C# if you want). Or on the web apps, with React.

• Happy to speak to our sales team and customers and develop features (i.e. a decent level of English)

• Worked in a similar fast-paced environment (startups, big tech, hedge funds, fintech, anywhere the tech is the product)

• CS/Maths/Engineering/Science/Philosophy Degree
  
  

Features 📋

• As our first UK-based mobile developer, you'll be expected to be largely self-sufficient while the team is small. You'll need to take the initiative, make smaller decisions and propose a course of action rather than expecting work to be fed to you.

• You’ll work with our excellent Ukranian Android developer and can potentially move into a leadership role as the team expands.

• You'll be contributing to big design choices that affect the entire system and working directly with our sales team and customers to design features.

• In return, we'll support you in making those decisions. We're small enough to be open-minded about tech

• Our mobile apps are native - Kotlin and Swift. Web frontends are React/Next/Swift/Kotlin based. The admin portal uses graphql. The softphone uses an auto generated OpenAPI typescript client. On the backend we use C#, .Net 6/7/8, and aim to be modern in our choices. We love types! We use Azure as our cloud

• We care most about UX and core product reliability, although we've not always been able to meet that goal (especially around UX), while looking to ship non-core features more quickly.

• We are doing some genuinely fun stuff around AI, as well as potentially around the nitty-gritty of VoIP

• Sane hours, flexible working. Moving fast shouldn’t involve 12 hour days.
  
  

Bugs 🐛

Perhaps these are red flags (and we'd all like to find that out sooner rather than later), but hopefully they're a list of things you're up for working on together.

• Our CI/CD process could probably be improved and more standardised

• Some of our services need close to 100% uptime. This makes deploying and working on them a little more painful

• Whilst there will be a lot of new features being built, there is a decent amount of “legacy” code that you’ll need to get to grips with.
