Lead MLOps Engineer

Most money apps talk at you. Cleo talks back ✨

We're not building another finance app. We're building the world's first AI financial assistant, one that actually understands your money and makes you better at it, and we're changing the world's relationship with money in the process 💰 For everyone, whatever their background or balance.

The proof: profitable, fast-growing, a unicorn with over $300M in ARR, and millions of people who now feel differently about their money.

We love original thinkers who challenge the status quo. We move fast, tell the truth, and there's nowhere to hide from good work here. If that excites you more than it scares you, you'll fit right in.

Meet the team 👥

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.

About The Role ✍️

We're hiring an engineer to sit between our product teams and the Data Platform team, helping product teams adopt the Data Platform's tools, frameworks, and processes so they can build scalable, efficient, and reliable data and ML solutions.

• Support product teams in achieving their OKRs while championing best practices in data engineering and MLOps
• Help teams implement robust data pipelines, model deployment workflows, monitoring strategies, and cost-efficient practices
• Act as the bridge between product teams and the Data Platform team, surfacing real-world challenges, gaps, and pain points in the existing platform

Collaborate with the platform team to continuously improve internal tooling and infrastructure for engineers and data scientists

Blend hands-on engineering with strategic impact, influencing both product success and the evolution of the data platform

What We're Looking For 🕵️

• Data system design and the ability to break down work
• Solid experience with a data engineering language (Python ideal)
• Knowledge of at least one distributed processing framework, ideally streaming (e.g. PySpark, Flink)
• Containerisation and orchestration - Docker, Kubernetes
• Infrastructure as Code - Terraform
• Software engineering best practices - proficiency in Python (preferred), code quality and maintainability
• Good knowledge of different storage types and when to use them - OLTP, OLAP, S3
• Understanding of value and product thinking
• Experience working cross-functionally with data scientists, software engineers, and product managers to align ML initiatives with business goals
• Nice to have: experience running streaming platforms and knowledge of stream-to-table and table-to-stream
• Nice to have: deep technical knowledge of core data structures and distributed processing, with a preference for practical application over theory
• Nice to have: monitoring and alerting as it pertains to data systems
• Nice to have: deploying APIs and systems outside of the core data platform, moving toward deploying ML systems
• Nice to have: experience working with feature stores
• Nice to have: experience building and managing ML pipelines (e.g. Kubeflow, MLflow, Airflow, Flyte)
