Site Reliability Engineer (SRE) - Remote

Overview

OpenFX is on a mission to move money as freely as data, unrestricted by time zones, banking hours, or legacy systems. We are building the infrastructure that powers the next generation of cross-border payment systems for institutions. Our early team comes with experience from J.P. Morgan, Goldman Sachs, FalconX, PayPal, Affirm, Kraken, and Nium, and we’re backed by Accel, Lightspeed, NfX, and other top-tier investors.

As a Site Reliability Engineer, you will ensure the reliability, availability, and performance of OpenFX’s systems. This is a hands-on, high-impact role at the intersection of DevOps and incident response. You will participate in on-call rotations covering U.S. operating hours, triage production issues in real time, and work with engineering pods to quickly resolve or escalate incidents.

In Short

• Serve as first responder for production incidents during U.S. operating hours (±2h EST).
• Lead triage during outages, analyzing logs, metrics, and traces to identify root causes.
• Drive incident postmortems and follow-ups to prevent recurrence.
• Communicate clearly and quickly during incidents to internal stakeholders.
• Own reliability outcomes across all OpenFX systems, focusing on uptime, latency, and error budgets.
• Enhance observability through logging, metrics, alerting, and dashboards.
• Optimize on-call processes and ensure smooth handoffs across IST, EST, and PST coverage.
• Proactively identify systemic reliability risks and propose improvements.
• Contribute automation and tooling to reduce manual incident handling.
• Champion best practices in reliability engineering and operational excellence.

Requirements

• 5+ years of experience in Site Reliability Engineering, DevOps, or Infrastructure Engineering.
• Proven experience leading incident response, running postmortems, and communicating during outages.
• Strong background with cloud infrastructure (AWS preferred), container orchestration (Kubernetes, ECS), and Infrastructure-as-Code (Terraform, CloudFormation).
• Familiarity with observability stacks (e.g., Prometheus, Grafana, Datadog, ELK, OpenTelemetry).
• Ability to triage errors at both the infrastructure and application level, and escalate effectively when deeper intervention is required.
• Ownership mindset with strong communication skills in high-pressure situations.

Benefits

• Competitive salary and benefits package.
• Equity in a rapidly growing company.
• Opportunity to work on mission-critical infrastructure in fintech.
• A collaborative team culture with a bias toward ownership and outcomes.
