Senior Machine Learning Site Reliability Engineer

• SRE & Cloud Engineering: Hands-on experience with SRE practices in production, strong AWS expertise, Kubernetes, networking, DNS, and Infrastructure as Code (Pulumi preferred, Terraform a plus)
• Automation, Software Engineering and MLOps: Demonstrate strong software engineering fundamentals with an emphasis on code quality and maintainability. This includes solid Python proficiency and deep knowledge of the Python ecosystem (testing, debugging, packaging), hands-on experience with PySpark, and a consistent focus on writing clean, well-structured, and maintainable code. Familiarity with MLOps practices such as model registries, model versioning, retraining workflows, and end-to-end deployment lifecycles is also expected
• Reliability, Data & Operations: Add stakeholder engagement and mentoring e.g. lead incident response and RCAs, improve system reliability, and engage stakeholders to propose solutions, share learnings, and mentor others

• Regulated Environments & Security: Experience operating in highly regulated industries (e.g. Insurance, Banking, Healthcare), managing sensitive data, and supporting secure networking setups, including exposure to security technologies such as Cloudflare
• Distributed Systems & Microservices: Strong understanding of microservices architectures, their principles and trade-offs, with the ability to troubleshoot and maintain distributed systems and supporting technologies (RabbitMQ, Kafka, PostgreSQL, Redis)
• Observability & Platform Operations: Hands-on experience with Datadog for platform and application monitoring, performance optimisation, and solid fundamentals in database structures and operational troubleshooting, with exposure to systems built in languages such as Rust and Elixir

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 Senior Machine Learning Site Reliability Engineer to join our Infrastructure 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.
