Description
Trintech is an award-winning AI-driven Fintech SaaS organisation transforming the way finance teams operate.
We are looking to hire a Lead Site Reliability Engineer to helm the technical delivery of reliability improvements across a broad service portfolio.
You will turn production evidence into a prioritised engineering plan, coordinate work across teams and ensure incident learning results in measurable improvement. This is a technical individual-contributor role with no direct reports.
You will remain hands-on across Kubernetes and OKD/OpenShift, Azure, VMware-based infrastructure, and Linux and Windows workloads. Grafana, Prometheus, Datadog, Sumo Logic and PagerDuty support investigation, service visibility and incident response.
YOUR IMPACT
• Own the integrated reliability engineering plan across services, regions and workstreams, with clear technical priorities and accountable follow-through.
• Strengthen the SRE team's effectiveness through practical direction, better operational tools, sustainable response practices and verified engineering outcomes.
WHAT YOU WILL DO
• Build a prioritised reliability roadmap from customer impact, incident recurrence, service risk and operational effort, agreeing delivery capacity with the SRE manager.
• Lead adoption of meaningful service indicators, objectives and error-budget decisions with product and service owners, establishing ownership and review practices.
• Coordinate alert improvements across Grafana, Prometheus, Datadog, Sumo Logic and PagerDuty, addressing duplication, missing coverage, routing and diagnostic context.
• Lead technical response to complex incidents and strengthen regional handovers, escalation readiness and blameless reviews; verify completion of consequential follow-ups.
• Direct and contribute to automation that removes repeated operational work, with code review, testing, bounded permissions and safe recovery behaviour.
• Coordinate readiness, capacity and recovery work across application, data, infrastructure and Platform Engineering teams, resolving dependencies and technical blockers.
• Review high-risk changes and remain hands-on through diagnosis, prototypes and targeted implementation where direct involvement improves the outcome.
• Report customer impact, reliability trends, repeat failures, alert quality and engineering progress; raise gaps in capacity or ownership with clear recommendations.
WHO YOU ARE
• A record of leading reliability improvements across multiple production services and teams, with evidence of sustained outcomes after delivery.
• Strong practical judgement across Kubernetes, Linux, application behaviour, networks, storage and hybrid infrastructure, with the ability to involve specialists effectively.
• Hands-on depth in monitoring, PromQL, log analysis and alert design, including the ability to distinguish telemetry faults from service failures.
• Experience leading significant incidents, improving on-call practices and driving corrective actions through to verified resolution.
• Credible software and automation skills, including reviewing and implementing maintainable, tested operational tooling and controlled changes.
• Ability to coordinate dependencies, mentor technical leaders and negotiate delivery priorities and reliability trade-offs without relying on line-management authority .
NICE TO HAVE
• Experience with OKD/OpenShift, Azure, VMware, Windows, Datadog, Sumo Logic, PagerDuty, Terraform, SaltStack, Azure DevOps or Argo CD.
• Experience supporting distributed teams and SaaS services with database, integration, batch-processing or customer-facing financial-workflow dependencies.
HOW YOU WILL WORK AND LEAD
• Set technical priorities and guide Senior and Principal contributors, agreeing resource commitments with their managers and retaining clear service ownership.
• Partner with the SRE…
