We’re not about selling products - we want to solve problems and change lives through Monzo ❤️   📍London / UK Remote | £85,000–£110,000 + Incentive Awards tied to your performance + Benefits About Machine Learning Platform Engineering at Monzo The Machine Learning Platform team builds the systems that help teams across Monzo train, evaluate, deploy and serve ML models and AI features safely and reliably. We work on backend services, Python libraries, model lifecycle tooling, evaluation workflows and low-latency serving systems. Our users are internal ML engineers, scientists and product teams building with ML and LLMs. The work matters because machine learning powers many important decisions and experiences at Monzo, from fraud checks and credit decisions to customer operations. We help teams move faster while keeping production systems reliable, observable and safe. This is a platform engineering role in the ML and AI space. We’re looking for someone who combines strong software engineering foundations with ML or AI context, and who enjoys building tools and systems for other engineers. 🧰 What you'll be working with... Go for backend services, platform APIs, and production systems Python for libraries, workflows, and tooling used by our ML engineers and scientists Feature platforms and data workflows using Chronon, Feast, and DataHub Model training pipelines and experiment tracking using Vertex AI and Comet AI observability, evaluation, and tracing using Langfuse and Bifrost AWS for real-time serving and online inference, GCP for batch compute and our BigQuery data warehouse. (Please note direct experience with all of them is helpful but not required and our interview process can be completed in any language). 🤩 We’d love to hear from you if... You combine solid backend engineering with real ML or AI platform experience (ML pipelines, feature stores, model serving, experiment tracking or LLM tooling) You’ve designed and operated distributed systems that handle scale, concurrency and failure You think like a platform engineer, focused on developer experience and removing friction for internal teams You’re happy working across both Go and Python You enjoy ambiguity and want to shape a platform as it grows You have experience with strongly typed languages, writing and working on backend software You’re curious about how systems behave in production, including reliability, latency, quality, safety and operational risk 🤔 This might NOT be the right fit if... Your background is predominantly SRE, DevOps or infrastructure operations You’re focused on data science or modelling You’ve shipped AI product features but haven’t worked on the platform side (serving, evaluation, model lifecycle) Levels We're on the look out for Engineers of varying levels at the moment. You can read more in our Engineering Progression Framework - we will interview you across the entire framework, so if you are not sure what level you are aiming for please chat to your recruiters!
