WeWork Reforma Latino (97001), Mexico, Ciudad de Mexico, Ciudad de Mexico Lead Site Reliability Engineer We're building a Site Reliability Engineering center in Mexico City, and we're hiring a Manager-level Backend Engineer to own the reliability and operational maturity of our settlement platforms. These are batch-critical systems that process every credit and debit transaction across the network. This is a foundational role. You'll be one of the first engineers in CDMX responsible for ensuring settlement cycles complete accurately, on time, and in compliance with SOX and PCI-DSS requirements. You'll work across hybrid infrastructure (on-prem data centers and AWS), partner closely with UK-based engineers, and build the automation and observability that allows Mexico City to operate settlement.

What You'll Do

Own reliability for batch settlement systems

ensure cycle completion windows are met, data integrity is maintained, and failures are detected before they reach downstream consumers

Build and improve observability for settlement pipelines - dashboards, alerts, and anomaly detection that make system health legible and reduce reliance on tribal knowledge

Drive automation of operational toil - certificate rotation, environment provisioning, compliance artifact generation, and manual validation steps that currently require human intervention

Partner with UK-based settlement engineers - acquire domain expertise on Durbin compliance windows, cross-border DCI routing, and acquirer/issuer SLA adherence

Participate in incident management - respond to settlement failures, drive root cause analysis, and implement durable fixes that prevent recurrence





Contribute to regulatory readiness - ensure SRE practices produce audit-ready artifacts for SOX and PCI-DSS exams without manual toil

What Success Looks Like

Independently validate and troubleshoot settlement cycle failures

At least two manual settlement operations processes fully automated

Settlement observability coverage sufficient to detect anomalies before cycle deadlines

Documented runbooks and severity criteria for all critical settlement failure modes

The Environment You'll work with batch processing systems that handle financial transactions across multiple on-prem data centers with active/active and active/passive configurations. The stack includes Java, Python, shell scripting, SQL, AWS, Kubernetes, OpenShift containers, Datadog, Observe, and legacy payment platforms. CI/CD pipelines, API automation, and secret management via HashiCorp Vault are part of daily operations. You'll leverage agentic AI automation (Claude Code or others) to accelerate development and build automation solutions. You'll need strong troubleshooting and debugging skills and be comfortable with both modern cloud-native tooling and traditional enterprise batch systems.
