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.
