Senior Python Engineer – ML Platform in London

Are you looking for a new challenge? Fancy helping us shape the future of motor insurance? Prima could be the place for you. Since 2015, we’ve been using our love of data and tech to rethink motor insurance and bring drivers a great experience at a great price. Our story began in Italy, where we’ve quickly become the number one online motor insurance provider. In fact, we’re trusted by over 5 million drivers. And now we’re expanding to help millions more drivers in the UK and Spain.

To help fuel that growth, we need a Software Engineer to join our Engineering team. This team is the beating heart of Prima. You’ll be joining over 350 engineers across software development, infrastructure, operations and security. Fueled by curiosity, experimentation and collaboration, you’ll help deliver scalable, impactful solutions that shape the future of insurance.

What you’ll do

• Contribute to the design and evolution of reliable systems and shared capabilities that support the full ML lifecycle—from experimentation to production.
• Take the lead in developing platform tools, shared services, and infrastructure that power Machine Learning at scale.
• Work within a dynamic team of engineers in the ML Platform Domain, providing technical guidance, mentorship, and support.
• Collaborate closely with product managers and stakeholders, including data scientists and ML engineers, to support the full ML lifecycle, from experimentation and training to deployment and monitoring.
• Continuously learn and stay up to date with emerging technologies, tools, and industry trends to ensure Prima’s ML platform remains robust and future-proof.

What we’re looking for

• 3+ years of professional experience in software development with Python.
• Strong knowledge of software design principles and architecture.
• Proficiency in software development practices like TDD and BDD, ensuring our code is marked by quality, readability, and maintainability.
• Practical Knowledge of CI/CD, IaC, containerization technologies.
• Experience working with messaging/streaming platforms (e.g. Kafka, RabbitMQ) and designing relational databases (e.g., MySQL, PostgreSQL).

Nice-to-Have

• Experience working with machine learning models and workflows in production environments.
• Proficiency in cloud-based systems (preferably AWS).
• Familiarity with Domain Driven Design.
• Experience with data and ML orchestration frameworks (e.g. Databricks, Airflow, Kubeflow).
• Experience in infrastructure as code (e.g. Terraform, CloudFormation, Pulumi), container orchestration (e.g. K8s, Knative) and Service mesh.

Why you’ll love it here

• Work Your Way: Enjoy full flexibility – work from home, the office or a mix of both. Plus, work from anywhere for up to 30 days a year.
