Site Reliability Engineer

Are you a Site Reliability Engineer looking for more than your next technical role? At EMBL-EBI, you’ll help build and evolve the platforms that make vital scientific data accessible to researchers around the world, while developing your skills, broadening your technical expertise and building a long-term career in infrastructure engineering. We’re looking for an engineer with a solid foundation in Kubernetes, Linux, automation and production services who is keen to take the next step.

About the Team

You’ll join the Applications Group, working within the Web Applications Platform Team. Led by David Ocaña, Head of Applications – Web Hosting & DB, the group sits at the intersection of IT infrastructure and scientific services, helping teams deliver the web applications and databases that underpin EMBL-EBI’s research resources. Our platforms support services used by the global scientific community, including resources such as Ensembl, UniProt and Expression Atlas. With billions of requests handled each month, reliability, scalability, security and performance are fundamental to what we do.

We’re continuing to evolve our web hosting platform, moving towards a more consistent, container-based approach built around Kubernetes and greater automation. Working closely with colleagues across Infrastructure and Operations, you’ll help shape how these platforms are designed, managed and improved. This is an exciting time to join us. As the team develops its technical direction and strengthens its approach to Site Reliability Engineering (SRE), you’ll have the opportunity to contribute ideas, learn from experienced colleagues and help establish the practices that will support our services into the future.

Just as importantly, we want to invest in your development. This role is designed for someone who has established their technical foundations and is ready to grow. As you build expertise and demonstrate increasing ownership, there is scope to progress towards a senior engineering role, with greater autonomy and opportunities to guide colleagues, and potentially towards a more strategic coordination role over time. Your development will be supported by practical experience, collaboration and the opportunity to take on progressively more complex challenges.

What you’ll do

You’ll help build, operate and improve the platforms that host EMBL-EBI’s public-facing scientific web services. This is a hands-on engineering role where you’ll develop your expertise in production infrastructure, automation, monitoring and service reliability, while contributing to a team-wide programme of continuous improvement. Your responsibilities will grow with you: from delivering reliable technical solutions and improving day-to-day operations to taking greater ownership of projects, helping shape engineering practices and supporting the wider team as your experience develops.

• Build and maintain our hosting platform: Contribute to the administration and evolution of our on-premises Kubernetes-based web hosting environment.
• Improve reliability and performance: Help ensure production services remain available, resilient, secure and responsive under demanding workloads.
• Automate and simplify operations: Develop and improve automation, configuration management and deployment processes to reduce manual effort and improve consistency.
• Develop our monitoring capabilities: Work with tools such as Prometheus and Elasticsearch to improve infrastructure monitoring, observability and insight into service performance.
• Support our delivery ecosystem: Help maintain and improve supporting technologies, including GitLab CI/CD and related tooling.
• Champion SRE practices: Apply and develop approaches that improve service reliability, operational efficiency, documentation and continuous improvement.
• Collaborate across teams: Work with colleagues in Applications, Infrastructure and Operations to solve problems, share knowledge and deliver improvements.
• Grow your technical ownership: Take increasing responsibility for tasks and projects, contribute to prioritisation and, as your experience develops, help guide technical decisions and support colleagues.

You will have

We’re looking for someone with a sound technical foundation, a practical approach to problem-solving and the curiosity to keep learning.

• A degree in Computer Science, or equivalent demonstrable professional experience.
• Around three years’ relevant experience designing, deploying or operating production infrastructure or large-scale web hosting services.
• Hands-on experience deploying and administering Kubernetes in an on-premises or cloud environment.
• Strong Linux administration skills, ideally with Red Hat Enterprise Linux (RHEL) or a related distribution.
• Experience with infrastructure automation and configuration management, using tools such as Ansible, Puppet or Terraform.
• Practical experience with Git, CI/CD pipelines and scripting or programming, ideally using Python.
• Understanding of infrastructure monitoring, production service management and approaches to improving reliability.
• A proactive, growth-oriented mindset, with a strong commitment to continuous learning, developing technical expertise, taking ownership and embracing opportunities to grow and progress within the team.
• Strong communication and collaboration skills, with the ability to organise competing priorities, document work clearly and share knowledge within a multidisciplinary team.

You may also have

You don’t need to tick every box, but additional experience in the following areas would be an advantage:

• Kubernetes certifications such as CKA, CKAD or CKS.
• Experience with public cloud platforms, particularly AWS or Google Cloud.
• Familiarity with automation and orchestration tools such as Jenkins or Rundeck.
• Knowledge of web application security principles and practices, including OWASP guidance.
• Experience working in Agile teams and contributing to iterative service improvement.

We value engineers who take ownership, communicate openly, support their colleagues and are enthusiastic about learning. You’ll bring your own expertise and perspective, while being willing to share knowledge, explore new approaches and help the team become even better at what it does.
