[Hiring] Senior Backend Engineer @Cleo

Role Description

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

• Shape the direction of upcoming work - break down ambiguous problems with your squad and help drive projects from early discovery through to shipped impact.
• Build and evolve the APIs, data models, and business logic behind our product; no Ruby experience required, just strong fundamentals and sound judgement on trade-offs.
• Contribute to testing, observability, and experimentation, and help continuously raise the bar on developer experience and product quality.
• Drive high-impact initiatives such as our secured credit card, budgeting and financial insight features, and subscription/pricing experiments.
• Mentor engineers at your level and beyond, share knowledge generously, and help build a culture where people grow quickly and have real influence.

Qualifications

• An experienced engineer with solid fundamentals, having worked across any modern tech stack - the specific language matters less than your ability to reason clearly, learn quickly, and think in trade-offs.
• A track record of writing maintainable, thoughtful code and making sound technical decisions with minimal oversight.
• Comfortable working with Ruby, or confident you can ramp up quickly in it - deep Ruby experience isn't required.
• Strong collaboration skills with product, design, and data partners, with genuine curiosity about users and their problems.
• Experience mentoring or raising the bar for engineers around you, and contributing positively to team culture.
• Motivated by Cleo's mission - you care about building products that genuinely improve people's financial health.
• Alignment with our engineering principles - autonomy, accountability, pragmatism, and building things that matter.

Benefits

• Meaningful equity.
• Comprehensive health, dental and vision insurance.
• Mental health support.
• A paid one-month sabbatical after four years.
• A learning and development platform.
• Pension or retirement contributions.
• Location-specific leave entitlements.

Company Description

Cleo's mission is to change the world's relationship with money. We can't do that without building a brilliant, genuinely diverse team - and making sure our hiring process gives everyone a fair shot, running a fair and transparent recruitment process in which every candidate is considered on their merits.
