Senior Site Reliability Engineer Job Summary The Senior Site Reliability Engineer is a key technical leadership role at the intersection of infrastructure, platform engineering, operational resilience, and developer enablement. At Partnerize, we operate a high-scale platform processing over a billion daily events across a hybrid estate spanning on-prem datacentres and AWS cloud infrastructure. You will play a critical role in ensuring our systems remain reliable, scalable, secure, and operationally efficient whilst helping evolve our engineering culture towards a modern "you build it, you own it" model. This is not a purely operational support role. We are looking for an experienced technical leader and subject matter expert who can balance hands-on engineering with strategic thinking - someone capable of modernising legacy systems, improving observability and automation, and guiding engineers through increasingly complex distributed environments. The Things You Care About At the heart of our platform, we process and distribute performance marketing data at enormous scale, generating over a billion events across our infrastructure daily. Our systems power real-time decision making, partner attribution, analytics, and customer-facing products that require high availability and operational excellence. As we continue to scale globally, we are evolving our infrastructure, modernising legacy systems, and investing heavily in automation, containerisation, observability, and platform reliability. We deploy to production multiple times a day and operate a hybrid environment spanning physical datacentres and AWS cloud services. Our infrastructure and engineering ecosystem includes technologies such as Linux, Kubernetes, Docker, Kafka, MySQL, PostgreSQL, Redis, Python, Terraform, Ansible, Elasticsearch, Druid, and modern CI/CD tooling. As a Senior Site Reliability Engineer at Partnerize, You Will: Lead Reliability & Operations Take ownership of platform reliability, availability, and operational performance across a complex hybrid estate supporting Partnerize, BrandVerity, Ascend, and Konnecto. Drive Platform Modernisation Help lead the transition from legacy operational models towards modern containerised infrastructure and self-service engineering platforms.

Mentor & Develop Engineers Act as a player-coach within the SRE organisation, mentoring engineers, supporting technical growth, and helping shape future technical leaders. Lead Incident Management Take ownership during major incidents, driving clear communication, structured troubleshooting, and pragmatic resolution strategies across the wider business. Drive Automation & Continuous Improvement Continuously improve infrastructure, deployment pipelines, monitoring, and operational tooling to improve reliability, scalability, and delivery velocity.
