Site Reliability Engineer (Mid / Senior) - Platform Infrastructure in London

Elastic, the Search AI Company, enables everyone to find the answers they need in real time, using all their data, at scale — unleashing the potential of businesses and people. The Elastic Search AI Platform, used by more than 50% of the Fortune 500, brings together the precision of search and the intelligence of AI to enable everyone to accelerate the results that matter. By taking advantage of all structured and unstructured data — securing and protecting private information more effectively — Elastic’s complete, cloud-based solutions for search, security, and observability help organizations deliver on the promise of AI.

The Infrastructure team sits at the foundation of the Elastic product stack, enabling engineering efforts across the entire company. We are software developers who specialize in managing state — CI pipelines, cloud resources, and cross-team integrations. The Elastic Stack is built on our infrastructure, and we own everything needed to get it there. Beyond that, we act as internal software consultants, putting our own products to work for Elastic's business.

Responsibilities

• Design and develop tooling that facilitates building, testing, and shipping the Elastic Stack.
• Build and operate production services that power core aspects of the Elastic business, including downloads, Docker registry, maps service, and more.
• Support internal adoption of the Elastic Stack for software development and analytics use cases.

Qualifications

• Software Developer: You have a broad development background and are deeply proficient in at least one language. Our team uses Python, JavaScript, Clojure, and Haskell, but we work alongside engineers across the company using everything from Java to Go — the specific language matters less than the depth of your expertise.
• Site-Reliability Engineering: We are fundamentally an operations team. We solve problems with code, but our core mission is keeping things running. Experience in an SRE or equivalent role is a strong indicator of fit.
• Service-Oriented: You have multiple years of hands-on experience administering Linux systems, ideally at scale and in distributed environments. Experience helping operate a SaaS platform is a plus.
• Infrastructure-as-code: You're comfortable automating production systems collaboratively — treating configuration as code, managing it through version control, and working with tools such as Docker, Terraform, Puppet, Chef, Ansible, Salt, Packer, Kubernetes, or your own well-crafted shell scripts.

Bonus Points

• A drive to automate and monitor everything. If it can be automated, you'll find a way.
• Experience building reusable software components; open source contributions (library, patch, documentation, or otherwise) are a bonus.
• Comfort with a versioned, Git-based workflow driven by issues and pull requests.
• Strong Linux fundamentals. You know your way around syscall tracing, TCP internals, init systems (sysvinit/runit/systemd), and aren’t afraid to go deep when a problem demands it.
• A passion for open source, whether through code, mailing lists, documentation, or community participation.
• Experience thriving in a distributed, asynchronous work environment with strong written communication habits.
• A genuine appreciation for diverse, globally distributed teams and a collaborative, inclusive approach to getting work done.

Benefits

• Competitive pay based on the work you do here and not your previous salary.
• Health coverage for you and your family in many locations.
• Ability to craft your calendar with flexible locations and schedules for many roles.
• Generous number of vacation days each year.
• Increase your impact - We match up to $2000 (or local currency equivalent) for financial donations and service.
• Up to 40 hours each year to use toward volunteer projects you love.
• Embracing parenthood with a minimum of 16 weeks of parental leave.

Take ownership of protecting the confidentiality, integrity, and availability of organizational data and systems by following applicable privacy and security policies, standards, and procedures. Ensure that all individual contributions follow Elastic’s Secure Software Development Framework (SSDF). Proactively participate in mandatory role-based training to ensure personal technical execution consistently aligns with the highest standards of data protection, data privacy, and system resilience.
