Jobs in Lisbon, Portugal

About the role

As a Senior Machine Learning Engineer at Iterable, you will design and build the end-to-end machine learning systems that power intelligence across our product. As a high-tech marketing platform, we work with thousands of large-scale and diverse enterprise customers. You will have real autonomy: from research and experimentation through to models running reliably in production, you'll own the systems and models behind our ML products and help shape the direction of AI at Iterable.

What you'll bring

• 5+ years of hands-on MLE experience putting complex models into production at scale.
• Databricks & Spark mastery: Real experience building, optimizing, and scaling production data pipelines using Databricks.
• Production-level Model Engineering: Proven track record of taking deep learning and ensemble architectures from training through optimization to production deployment.
• Production Code: Strong Python and/or Scala skills with an emphasis on readable, modular, and maintainable systems code.
• Systems & Infra Experience: Hands-on work with microservice backends, distributed compute (Ray/Spark), and containers (Kubernetes).
• Pragmatism: You care more about serving latency, reliability, and measurable customer impact than novel theoretical architectures.
• Prior work on large-scale recommendation systems.
• Experience setting up feature stores or model observability tools.
• Exposure to Infrastructure-as-Code (Terraform, Pulumi).
