Proof of work

The team

We are seeking an experienced Senior AI/ML Engineer to join our Core Services team. Our team focuses on building and maintaining some of the core APIs that power Kraken’s user experience, ranging from funding accounts and moving assets to fraud prevention and transaction analysis.

In this role, you’ll be a key contributor in designing and implementing a robust, scalable, and developer-friendly AI/ML platform. This platform will enable data scientists, analysts, and engineers to efficiently build, train, and deploy models that support anti-fraud and compliance monitoring initiatives across the organization.

You’ll thrive here if you have an exceptional eye for detail, take pride in writing performant, secure, and scalable software, and enjoy bridging the gap between data science and production engineering.

The opportunity

Design and implement robust Python services and libraries to power real-time fraud detection and compliance monitoring systems.
Build scalable batch and streaming data pipelines for feature building, model inference, and training, with strong guarantees for data quality, latency, and reliability.
Develop and operate a developer-friendly ML platform, including feature stores, data validation tooling, and model-training pipelines with automated quality checks.
Support ML model lifecycle management — from feature engineering and experimentation to deployment, monitoring, and performance tuning.
Manage and optimize real-time data infrastructure, leveraging technologies such as Kafka, Apache Flink, and Kubernetes/Nomad.
Work closely with experienced Python and Rust engineers, data scientists, and business stakeholders.
Mentor junior engineers, foster best practices, and help shape a strong engineering culture.
Stay current with MLOps, AI infrastructure, and data engineering trends, bringing innovative solutions into production.
