Senior Product Engineer - Ruby

At Cleo, we are embarking on a mission to fundamentally change humanity's relationship with money. Imagine a world where everyone, regardless of background or income, has access to a hyper-intelligent financial advisor in their pocket. That is the future we are creating. Cleo is a profitable, fast-growing unicorn with over $200 million in ARR and growing over 2x year-over-year. This is a chance to join a team of brilliant, driven individuals who are passionate about making a real difference.

Responsibilities:

• Joining a cross-functional product squad and collaborating with engineers, designers, analysts and other disciplines to develop features that enhance our users' financial health.
• Collaborating with senior peers in your squad and pillar to provide technical insight into upcoming work, and leading the delivery by helping pull everyone together to get it shipped.
• Mentoring colleagues to help them grow as engineers and actively supporting their development.
• Working on our Ruby on Rails monolith, building data models, APIs, and business logic services.
• Delivering your work using agile methodologies and tools like tests, observability, AB-tests, and feature flags.
• Analyzing data to identify problems and generate new ideas, using various sources such as our database, application logs, and user research data.
• Supporting colleagues through in-hours support and optionally joining the compensated out-of-hours on-call rotation.
• Contributing to cross-cutting concerns that improve our engineering efforts.
• Taking part in shaping the work of your squad beyond technical aspects, participating in product ideation, user research, design reviews, retrospectives, and more.

Here are some examples of the kinds of product feature work our engineers have taken part in over the last year:

• Building a secured credit card
• Launching new budget analysis features
• Implementing pricing experiments for subscriptions

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 are 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 and ideas from all levels are valued: we are all owners at Cleo.
