Senior Site Reliability Engineer - Linux Systems & Application Observability

<p><strong>Company Name: </strong>tastytrade</p> <p><strong>Role: </strong>Senior Site Reliability Engineer - Linux Systems &amp; Application Observability</p> <p><strong>Location: </strong>Chicago, IL (Hybrid, 3 days/week in office)</p> <p><strong>Role Summary</strong><br>Come join tastytrade, part of IG Group, as we build the reliability practice behind the brokerage platform<br>that active options, futures, and equities traders rely on every market day. As our first Senior Site<br>Reliability Engineer, you'll harden the systems behind order execution and market data delivery —<br>designing for fault tolerance, closing gaps in our telemetry, and making sure our HashiCorp Nomad-based<br>service fabric scales cleanly as trading volume grows. You'll work embedded alongside our infrastructure<br>and application engineering teams, contributing directly to our Ruby, Java, and Elixir services. This is a<br>rare opportunity to shape a practice and a culture from day one, on a platform where every order, quote,<br>and position has to be right, because real client capital is on the line.</p> <p><strong>What You'll Do (Job Responsibilities)</strong><br>• Build self-healing, fault-tolerant infrastructure and internal tooling that automates repetitive<br>operational work and reduces toil for Platform and Application teams.<br>• Run gap analysis across our observability stack to find blind spots in telemetry, logging, and alerting<br>coverage, then close them so failures surface before customers feel them.<br>• Own scalability work across our HashiCorp Nomad service fabric: capacity planning, load testing,<br>and identifying architectural bottlenecks before they become incidents.<br>• Extend our observability stack (Prometheus, Honeycomb, OpenTelemetry) with the instrumentation<br>needed to actually see the failure modes above.<br>• Set SLOs and error budgets with multi-window burn-rate alerting for critical brokerage flows, once<br>the fault-tolerance and telemetry foundation is in place.<br>• Mentor engineers across teams to build a culture of site reliability champions so the practice outlives<br>any one person.</p> <p><br><strong>Who You Are (Skills Needed)</strong><br>• Hands-on experience designing fault-tolerant, self-healing distributed systems — not just describing<br>the patterns, but having shipped them.<br>• Deep understanding of one or more: distributed systems, Linux systems, cloud-native architectures,<br>containerization.<br>• Experience running gap analyses on observability/telemetry systems: identifying what's not<br>instrumented, not alerted on, or not visible until it's too late.<br>• A track record scaling systems
