We are evolving our Site Reliability Engineering capabilities to strengthen reliability, observability, security, and operational excellence across our Risk Intelligence division.
Role Overview
As a Senior SRE, you will be a senior hands‑on technical person helping shape the foundations of reliability across both new and existing platforms. You will collaborate with Architecture, Engineering, Security, and Platform teams to ensure reliability is built into systems from day one. While this is not a people‑management role, you will work closely with global teams and may be called upon for major incidents or critical issues. This position requires a highly proactive, hard‑working expert with strong leadership presence and ownership of platform reliability outcomes.
Key Responsibilities
* Lead the establishment of SRE foundations for new projects, building environments, monitoring, alerting, and ensuring operational readiness from day one.
* Define, implement, and champion observability standards, tooling, and guidelines across metrics, logs, traces, and SLIs/SLOs.
* Design and evolve monitoring and alerting solutions that improve visibility, reduce toil, and strengthen system health.
* Continuously drive reliability improvements across our environments through incident reduction, performance tuning, and building resilient patterns.
* Partner with Security teams to ensure our platforms meet compliance, security, and risk‑management expectations.
* Influence architectural and design decisions through data‑driven cloud cost optimization and efficiency initiatives.
* Be a technical leader and mentor supporting engineers, shaping engineering standards, and fostering a culture of learning and development.
Education & Qualifications
Education: Bachelor’s Degree or equivalent experience in Computer Science, Engineering, or a related field.
