Clove

Join us to build the future of financial advice - personal, accessible, and built for today. Financial advice has been too expensive, exclusive, and out of reach for too long. At Clove, we’re combining trusted advisers with technology to close the advice gap and help people make smarter decisions with their money. As one of our first hires, you’ll shape how advice works for today - personal, accessible, and built around real lives. You’ll own the Android app experience end-to-end, from early prototypes to polished releases. You’ll work closely with design and our other engineers to solve real problems from first principles, shaping the approach as you go, and turn that into interfaces that feel simple, fast, and trustworthy. We’re a small team, so this role is a mix of design-minded engineer and engineering-minded designer: you’ll sweat the details, iterate in tight loops with design, and turn high taste into shippable, maintainable product. In a world where the “can we build it?” bar keeps dropping, the real differentiator is how the app makes someone feel - confident, in control, and cared for. And beyond that: a little bit like they’ve got superpowers. It should be fun. It should feel genuinely magical; through the details of the UI, motion, and interaction design. Your background * Product-minded: you care about the user problem, you ship, and you iterate based on data and user feedback. * Strong Android engineering fundamentals and a track record of shipping high-quality apps. * High ownership and autonomy: you can take ambiguous problems from “vague” to “shipped”, bring others along, and drive them through to impact. There are no PMs here. * A true self-starter: you don’t wait to be told what to do, and you take ownership end-to-end. * You don’t settle for mediocrity. You push the quality bar and keep raising what “great” looks like. * A love of building and learning by doing: you prototype, measure, iterate, and you enjoy the loop. * First-principles thinking and healthy skepticism: you ask “why?”, challenge assumptions, and look for simpler, better foundations. * Excellent product taste: you care about typography, spacing, motion, and the “last 10%” details that make an experience feel premium. * Comfort building complicated UI and stateful flows with clean, maintainable code. Nice-to-haves * Jetpack Compose expertise and experience designing reusable UI systems. * 0→1 experience: you’ve taken a product from a blank page to something people love. * Comfortable with backend technologies and collaborating across the stack. * Comfortable diving into analytics dashboards, understanding what’s happening, and turning it into product improvements. * Comfortable talking directly with users. * Experience working in regulated or high-trust environments (fintech, health, identity), where clarity and correctness matter. * Experience working in an early-stage team where you set patterns, not just follow them. Your impact * Build and ship new onboarding and advice experiences with a strong bias for experimentation and learning. * Create complex, high-craft interfaces (dynamic forms, rich state, thoughtful motion, and edge-case handling) that still feel effortless to use, including polished animations and transitions that communicate state, reduce cognitive load, and make the experience feel premium. * Push what’s possible on Android: modern UI patterns, performance, accessibility, and delightful micro-interactions. * Set the foundations for Android engineering at Clove: architecture, quality bar, testing, release cadence, and observability. * Partner tightly with design and product to iterate quickly, then refine until it’s genuinely excellent. Our offer A chance to join a small, senior team building Clove from the ground up. You’ll have ownership, flexibility, and real impact - backed by trust, momentum, and a mission that matters. Our process We keep it simple: real conversations with the founding team, practical exercises if useful, and clarity about what we expect from each other. No hoops for the sake of it.

We’re searching for product-focused Android engineers to evolve our native mobile app. You’ll take pride in building polished user experiences, and you’ll balance the need for well-tested resilient code with moving fast and iterating.  You’ll be working on a product that is a part of day to day life for more than 11 million people already, and your work here will shape the way that people interact with their finances. As an Android Engineer at Monzo you'll work in a small, autonomous product squad alongside iOS Engineers, Backend Engineers, User Researchers, Product Designers, Product Managers, QA Testers, and Data Scientists.

Mobile engineers at Monzo work on everything from the personal banking product to customer support tools. We also have a small mobile platform squad dedicated to enabling other engineers to move faster. Every week we meet as an Android discipline to discuss tools, techniques, problems we're encountering across the company and work together to improve our codebase and processes. You'll report to an engineering manager who will meet with you every 1-2 weeks 1:1. They’re dedicated to helping you grow and develop as an engineer. OUR ANDROID APP Our app is 100% Kotlin, built using MVVM (Model View ViewModel) and Coordinators, and modularised by product feature. We use RxJava, Retrofit and Moshi for API calls and Dagger for dependency injection. We’re starting to use Coroutines for most new features. Room is our choice for persistence, and we use repositories for interacting with data. We’ve built out our design system with Compose.  We use GitHub Pull Requests to do code reviews, and write unit tests for our ViewModels, Coordinators, and any other classes which contain logic. We write tests for all of our Compose screens and snapshot test them with Happo. We also use Espresso to test flows, which are executed via our continuous integration system. We’ve previously written about building Monzo Chat on Android, which goes into detail on some of these elements. 🤩 WE’D LOVE TO HEAR FROM YOU IF… * You care about the impact your work has on our customers, and optimise for outcomes rather than the number of lines of code you output * You’re excited about and have experience in programming in Kotlin * You’ve shipped and iterated on at least one app in the Play Store * You have a product mindset: you care about customer outcomes and you want to make data-informed decisions * You love turning excellent design into beautiful products * You’re comfortable working in a team that deals with ambiguity * You have an understanding computer science principles We're on the look out for L30 Engineers at the moment, you can read more in our Engineering Progression Framework you will be interviewed across the whole framework, so if you're not sure what level you're aiming for chat to your recruiter!  🙌WHAT’S IN IT FOR YOU: 💰Base salary range for this role is depending on experience + equity + stock options & benefits  💰 Base salary for this role is depending on experience + Incentive Awards tied to your performance  + benefits  ⏰ We offer flexible working hours and trust you to work enough hours to do your job well, at times that suit you and your team. 📚Learning budget of €1,200 a year for books, training courses and conferences 🌈 THE APPLICATION JOURNEY HAS 3 KEY STEPS Our interview process involves three main stages:  1.
