Machine Learning Engineer

ComplyAdvantage TechnologyAt Comply, we are building cutting-edge solutions that help prevent money flowing to and from bad actors to create a safer world. Your work will allow our customers to find out who is associated with crimes, financial and political risks, what that association is, and when it occurred, and it will dynamically update their state as new information emerges across a huge range of sources.In our Entity Resolution Team we build and maintain data pipelines and services to perform Entity Resolution at scale. We use various ML and DS techniques to curate entities by ensuring their consistency and uniqueness across millions of data points. We define success via metrics representing our clients’ experience around minimising risk while also controlling operational costs.What You Will Be DoingAs a Machine Learning Engineer, you willBuild/train and productionize machine learning models for your squadBuild capabilities to monitor model performance and feature driftWhere appropriate re-use public models and techniques such as prompt engineering and RAG to reduce time to valueCollaborate with other software engineers in a cross functional team to design and implement intelligent servicesDesign software with scale, transparency and ease of operation in mind, writing maintainable, performant and well-tested code in PythonIntegrate ML models into new and existing data pipelines to drive positive impacts for CA’s customers, including feature engineering as well as building APIs and consuming and producing event streams as inputs and outputs of modelsOur Tech Stack:Our technology stack is designed to run on public cloud architectures, notably AWS and GCPWe use Python and Kotlin in the backend and TypeScript, ES6 and React in the frontendWe make substantial use of modern database technologies (eg. Yugabyte) as well as Spark and cloud based object stores for big data processingWe also use an event-sourced model powered by Kafka for our communication bus and gRPC for our intra-service communication protocolOur data and AI teams use a wide range of machine learning libraries, large scale hybrid columnar data stores such as Databricks, Spark for stream and big data processing in combination with Kafka, as well as some graph databasesWe use modern observability solutions (Grafana) and deploy our code using ArgoCDWe have a strong emphasis on engineering excellence and strive to ship the best possible code and the best possible solutions to our customers.About you:Experience maintaining and scaling machine learning-powered applications in production environments. Experience building scalable backend applications (preferably with Python). A track record of working in multi-disciplinary teams alongside Data Scientists, ML Engineers, and Product Managers. Hands-on experience with cloud platforms (AWS, Azure, or GCP) or with containerized infrastructure (e.g., Kubernetes, Docker, ArgoCD, Argo Workflows). Strong communication skills and a collaborative mindset, with the ability to contribute to system design discussions and mentor more junior engineers. Nice to have:Experience working with PySpark or other distributed data processing frameworks. Background in building data-intensive applications or distributed systems using map-reduce style architectures. Familiarity with event-driven or microservice architectures. About us:Our mission is to empower every business to eliminate financial crime.By harnessing AI, a unified platform, and an extensive partner ecosystem, we help customers turn compliance into a catalyst for growth, operational resilience, and enduring regulatory trust.More than 3,000 enterprises across 75 countries rely on our end-to-end platform and the world’s most comprehensive financial crime risk intelligence. With full-stack agentic automation, we help organizations automate up to 95% of KYC, AML, and sanctions reviews, cut onboarding times by 50%, reduce false positives by 70%, and handle 7x more work with the same staff.ComplyAdvantage is headquartered in London and has global hubs in New York, Lisbon, Singapore, and Cluj-Napoca.
