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

Our Mission You call. You wait. You call again. In every other part of your life, you book in seconds. In healthcare, you’re blocked. We’re here to give power to the patient. For nearly 20 years, we’ve built the leading healthcare marketplace - helping tens of millions of people find and book the care they need. Now, we’re going further: building our infrastructure beyond Zocdoc’s marketplace to power access to care wherever patients search, from provider websites and insurance directories to search engines, AI platforms, and more. Healthcare still lacks something every other major consumer industry takes for granted: a seamless way to go from seeking to getting . We don’t want to own the front door to care; there isn't one. We want to make sure all of those doors open when patients are knocking. Fixing healthcare starts with fixing access to it. And we're still just getting started. Your Impact on our Mission: Zocdoc is looking for a Senior Site Reliability Engineer to make our distributed production systems more observable, reliable, and safe to change. Our platform connects patients, providers, and many interconnected services and integrations, so reliability depends on understanding the full path of a request—not just whether an individual service is running. You’ll help build the observability foundations, automation, and engineering practices that allow Zocdoc to move quickly without sacrificing safety. You’ll work across cloud infrastructure, microservices, APIs, and integration points in AWS, partnering closely with product engineering teams to identify risks, improve operational visibility, and make the right behavior easier to build and operate. You’ll enjoy this role if you are… Passionate about observability and believe that teams can’t reliably operate what they can’t see Experienced in integration-rich environments where APIs, third-party dependencies, asynchronous workflows, and distributed services create complex failure mode
