Senior Site Reliability Engineer

Tapcheck is hiring a Senior Site Reliability Engineer to anchor the shift from DevOps to a Site Reliability Engineering practice. The role will improve reliability of critical payment paths through SLOs, observability, resilient cloud infrastructure, safer deployments, and incident leadership.

Responsibilities:

• Define tiered reliability standards for our services (availability, monitoring, recovery, on-call, and security), and run the production readiness reviews that hold new services to them
• Lead our regional resilience work so critical payment flows keep running through a cloud region outage
• Build security and compliance into the platform itself, so SOC 2 and PCI DSS evidence comes from the system rather than from manual collection
• Make sure we catch production incidents before customers do, with alerting that reaches the right person at the right time for the right reason, and almost never otherwise
• Partner with product engineering to define SLOs and error budgets for critical user journeys, and use them to guide release decisions
• Grow our internal deployment platform into a self-service, governed path to production that doesn't need a ticket to SRE
• Make safe delivery the default, with progressive rollouts, automated rollback, and release controls teams get for free
• Replace manual access requests and provisioning with self-service, least-privilege workflows
• Bring our cloud environment fully under infrastructure as code, with policy as code enforcing tagging, security baselines, and cost visibility
• Share the on-call rotation and serve as incident commander and senior escalation point for major incidents
• Run blameless postmortems that fix systems, not people, and see the follow-up work through to done
• Measure toil and automate it away, using AI tools where they make detection, diagnosis, or remediation faster, with guardrails suited to a regulated environment
• Be the senior technical voice on cloud architecture and reliability, and write the design docs that turn decisions into shared practice
• Mentor engineers on the team and across product engineering, and guide the technical work of partner and contract engineers
• Make work and risk visible early; on this team, a slip is okay and a surprise is not

Requirements:

• candidates must already possess the right to work in the United States without the need for employment-based visa sponsorship now or in the future
• Spent 6+ years in SRE, platform, or infrastructure engineering, running production systems where downtime had real customer or financial impact
• Operated production workloads on Azure in depth, including PaaS compute, managed databases, messaging, private networking, and Entra ID
• Written production-quality code in Go, Python, C#, or PowerShell, and built tooling other engineers adopted
• Managed infrastructure as code at team scale with Terraform or OpenTofu, including modules, state, and pipeline-driven change
• Defined SLOs or equivalent reliability targets and built the monitoring and alerting to back them
• Led incidents as commander or senior responder, and run blameless postmortems that produced lasting fixes
• Explained technical risk and trade-offs clearly in writing, to engineers and to non-technical leaders
• Worked in fintech, payments, or payroll, where the availability and correctness of money movement matter
• Supported SOC 2 or PCI DSS audits as the engineer whose systems produced the evidence
• Designed multi-region resilience or run disaster recovery exercises
• Built or contributed to an internal developer platform or self-service deployment tooling
