Job description

Harrison Clarke partners exclusively with venture-backed technology companies building category-defining products. We are currently conducting a confidential retained search on behalf of one of our flagship portfolio companies, a well-capitalised, mission-driven technology firm that has been operating at scale since 2014, with millions of global users and a reputation for rigorous engineering.

The Role

As Senior Site Reliability Engineer, you will own the infrastructure foundation that the entire engineering organization depends on. This isn't a support function, it's a strategic one. You'll work at the intersection of reliability, scalability, and developer experience, ensuring that a high-availability distributed system stays fast, resilient, and ready to grow.

What You'll Be Doing

• Maintaining, improving, and securing cloud infrastructure across AWS and GCP, alongside Linux systems at scale
• Partnering directly with engineering teams to streamline deployment, packaging, and troubleshooting of complex distributed applications
• Driving CI/CD maturity using Jenkins and adjacent tooling
• Building, operating, and continuously improving Kubernetes clusters in production; serving as the internal authority on container orchestration
• Leading application migration efforts onto Kubernetes in close collaboration with development squads
• Owning internal platform services including Prometheus and ELK
• Monitoring high-availability environments and responding to incidents with urgency and rigour; conducting thorough, blameless post-mortems
• Participating in architecture and code reviews, setting the bar for infrastructure best practice
• Evaluating emerging technologies and making pragmatic decisions on adoption
• Identifying and eliminating toil through intelligent automation

What You Bring

• 5+ years in cloud-based systems operations as an SRE or DevOps engineer
• Hands-on experience with infrastructure as code and configuration management
• Strong command of SRE methodologies: SLOs/SLIs/error budgets, capacity planning, disaster recovery testing
• Deep understanding of networking fundamentals
• Proven track record managing production workloads with sophisticated monitoring and alerting
• Comfort with on-call responsibilities and a systematic approach to incident management
• Proficiency in at least one scripting or programming language
• A collaborative, low-ego working style — you raise the team up, especially under pressure

Bonus Points

• Ability to read and reason about Go, Rust, C++, or TypeScript
• Experience applying AI-driven approaches to operational automation
