Job Description
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.
