Lead Site Reliability Engineer

Description

About the role

At Trintech, the Lead Site Reliability Engineer leads 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.

What you will bring

• 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 manager on on-call readiness and protected engineering capacity; provide coaching and technical input into development and recruitment.

• Make delivery and recovery decisions within agreed authority, escalating business-risk acceptance, funding and organisation-wide architecture choices to accountable owners.

What success looks like

• The reliability roadmap delivers measurable reductions in customer disruption, recurring incidents and avoidable operational effort.

• Critical services have agreed owners, meaningful health measures, actionable alerts and tested recovery procedures.

• Regional handovers, escalation and incident follow-ups work consistently, with response load and capacity constraints visible to management.

• Teams deliver coordinated improvements with verified outcomes while engineers develop stronger independent technical judgement.
