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.

Here Are Some Examples, Big And Small, Of The Kinds Of Product Feature Work Our Engineers Have Taken Part In Over The Last Year

*   Building a secured credit card from scratch to help our users improve their credit scores without changing their habits.
*   Launching our new budget rewind feature to help users understand their pay-cycle and provide them with better analysis of how they got on with their budget.
*   Adding discount plans and tiering options to our subscriptions so we can experiment with the best pricing for different types of users.

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. **Our 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. While we take a pragmatic approach, we place a strong emphasis on quality. Our code is peer-reviewed, and we maintain automated testing using Minitest and CircleCI. We're also actively working towards a more 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 & ideas from all levels are valued: we are all owners at Cleo. **About You** Firstly and most importantly, all of the above sounds exciting to you and you want to make a positive difference in society by improving the financial health of our users worldwide.

You share and embrace these opinions and are passionate about using them to deliver value. For this frontend focused role, we also have some specific asks:

*   As this is an SE3/SE4 position, we’re looking for someone with strong industry experience of using React Native / React with TypeScript for a minimum of 5+ years. If it’s a less than that, maybe you want to look at our Product Engineer 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.

**What do you get for all your hard work?**

*   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/
*   Work at one of the fastest-growing tech startups, backed by top VC firms, Balderton & EQT Ventures
*   A clear progression plan. We want you to keep growing. That means trying new things, leading others, challenging the status quo and owning your impact. Always with our complete support.
*   Flexibility. We can’t fight for the world’s financial health if we’re not healthy ourselves. We work with everyone to make sure they have the balance they need to do their best work
*   Work where you work best. We’re a globally distributed team. Our Poland team works fully remotely, but we host virtual socials and an annual company offsite somewhere in Europe with all expenses paid.
*   Other benefits;

*   Company-wide performance reviews every 6 months
*   Generous pay increases for high-performing team members
*   Equity top-ups for team members getting promoted

_We strongly encourage applications from people of colour, the LGBTQ+ community, people with disabilities, neurodivergent people, parents, carers, and people from lower socio-economic backgrounds._ _If there’s anything we can do to accommodate your specific situation, please let us know._ **Poland App access:** The Cleo app is not downloadable in Poland right now. Why? 99% of our users are based in the US – where financial health is often overlooked. We’ve decided to shift our focus to where we can provide the most value and make the greatest impact for users who need it most.
