Backend Engineers (Ruby)

Here at Cleo, we have ~200 Engineers organised into Pillars ✨ Our stack spans a Ruby on Rails monolith, a single React Native (TypeScript) app frontend, Python for machine learning services, and PostgreSQL, all hosted on AWS and shipped through Kubernetes - backend goes out multiple times a week, app releases to Google and Apple at least weekly. To thrive here, our engineers proactively use our Engineering Principles to guide daily decisions, take ownership of problems beyond their own squad to drive broader impact, and actively drive their own learning, development and growth.

We're hiring Backend Engineers to join one of our cross-functional product squads - working closely with other engineers, designers, analysts, and other disciplines to build features that improve our users' financial health.

Key responsibilities for this role include:

Work on our Ruby on Rails monolith, building data models, APIs, and business logic services

Collaborate with peers across your squad and pillar, providing technical insight into upcoming work and helping pull the team together to ship it

Deliver your work using agile methodologies and tools like tests, observability, A/B tests, and feature flags

Mentor colleagues to help them grow as engineers, and actively support their development

Contribute to cross-cutting concerns that raise the bar across engineering

Shape your squad's work beyond the technical - take part in product ideation, user research, design reviews, and retrospectives

Solid experience with Ruby on Rails, building data models, APIs, and business logic services in a production monolith

Comfortable delivering with agile methodologies and practices like automated testing, observability, A/B testing, and feature flags

A collaborative approach — you work well with product, design, and analytics partners, and enjoy shaping work beyond just the technical bits

Experience mentoring colleagues and supporting their growth as engineers

Alignment with our company values and engineering principles

Cleo's mission is to change the world's relationship with money.
