What you’ll be doing

Responsibilities

• Joining a cross-functional product squad with a mix of frontend engineers, designers, UX writers, backend engineers, data analysts and others to develop features that improve our users’ financial health
• Working on our React Native application, building out amazing experiences for our users which bring financial health to life in the unique Cleo tone of voice
• Writing automated tests alongside your code to give us the confidence to ship it
• Using AB-Tests, feature flags and other tools that let us iterate quickly
• Using data to dig into user journeys, detecting problems and helping to optimise the Cleo experience
• Being part of the rota for our weekly app releases to the Apple and Google app stores
• Getting involved in cross-cutting concerns that lift our entire engineering effort with the rest of the frontend chapter
• Taking part in shaping all the work your squad does, not just the technical parts. Delivery is a team sport, and we encourage everyone at Cleo to share their ideas, so you can expect to be involved in product ideation sessions, user research calls, design reviews, retrospectives, ways of working sessions, product demos, OKR reviews

Whichever squad and part of the business you land in, you will be shipping changes multiple times a week to our hundreds of thousands of active users and seeing your work having a material impact on the financial health of those most in need.

About You

You are passionate about making a positive difference in society by improving the financial health of our users. You align with our company values and engineering principles, which drive our ways of working and software delivery.

For this frontend focused role, we also have some specific asks:

• As this is an SE2/SE3 position, we’re looking for someone with strong industry experience of using React Native / React with TypeScript for a minimum of 2+ years. If it’s a lot more than that, maybe you want to look at our Senior role.
• As your work will primarily involve working on features for our mobile apps, we’d either like to see some proven experience in this area or a genuine passion for moving into the mobile app space.

Tech Stack

Cleo is built as a Ruby on Rails monolith with a single React Native app frontend, utilising TypeScript. We also leverage Python for machine learning services and PostgreSQL for our database, all hosted on AWS. Our CI/CD pipeline is fully automated, with production deployments happening on every merge via Heroku. Our backend engineers deploy multiple times a week, and we release our frontend app to Google and Apple for review at least once a week.

We place a strong emphasis on quality. Our code is peer-reviewed, and we maintain automated testing using Minitest and CircleCI. We’re actively working towards a modular architecture, focusing on separating concerns to achieve all the benefits of microservices within a monolith, while progressively refactoring our code as we build new features. Everyone in the engineering team contributes to driving our technical strategy; voices from all levels are valued: we are all owners at Cleo.

Benefits & Perks

• A competitive compensation package (base + equity) with bi-annual reviews, aligned to our quarterly OKR planning cycles. You can view our public progression framework and salary bandings here: https://cleo-ai.progressionapp.com/
