Company Name: tastytrade Role: Senior Site Reliability Engineer - Linux Systems & Application Observability Location: Chicago, IL (Hybrid, 3 days/week in office) Role Summary Come join tastytrade, part of IG Group, as we build the reliability practice behind the brokerage platform that active options, futures, and equities traders rely on every market day. As our first Senior Site Reliability Engineer, you'll harden the systems behind order execution and market data delivery — designing for fault tolerance, closing gaps in our telemetry, and making sure our HashiCorp Nomad-based service fabric scales cleanly as trading volume grows. You'll work embedded alongside our infrastructure and application engineering teams, contributing directly to our Ruby, Java, and Elixir services. This is a rare opportunity to shape a practice and a culture from day one, on a platform where every order, quote, and position has to be right, because real client capital is on the line. What You'll Do (Job Responsibilities) • Build self-healing, fault-tolerant infrastructure and internal tooling that automates repetitive operational work and reduces toil for Platform and Application teams. • Run gap analysis across our observability stack to find blind spots in telemetry, logging, and alerting coverage, then close them so failures surface before customers feel them. • Own scalability work across our HashiCorp Nomad service fabric: capacity planning, load testing, and identifying architectural bottlenecks before they become incidents. • Extend our observability stack (Prometheus, Honeycomb, OpenTelemetry) with the instrumentation needed to actually see the failure modes above. • Set SLOs and error budgets with multi-window burn-rate alerting for critical brokerage flows, once the fault-tolerance and telemetry foundation is in place. • Mentor engineers across teams to build a culture of site reliability champions so the practice outlives any one person. Who You Are (Skills Needed) • Hands
