Job summary

tastytrade, part of IG Group, seeks a Senior Site Reliability Engineer to harden systems behind order execution and market data delivery. You will design for fault tolerance, close telemetry gaps, and scale a Nomad-based service fabric as trading volume grows.

Collaborate with Ruby, Java, and Elixir teams to improve telemetry and reliability. You will set SLOs, lead on-call response, and mentor peers to establish a lasting SRE culture.

Qualifications

• Hands-on experience designing fault-tolerant, self-healing distributed systems.
• Deep understanding of distributed systems, Linux systems, cloud-native architectures, containerization.
• Experience running gap analyses on observability/telemetry systems: identifying what's not instrumented, not alerted on, or not visible until it's too late.
• Track record scaling systems under real production load, including capacity planning and architectural bottleneck identification.
• Hands-on experience with OpenTelemetry, Prometheus, and Grafana, with the ability to instrument services directly.
• Strong Linux internals and networking fundamentals, including TCP/IP, UDP/multicast, packet capture, and flow analysis.
• On-call experience on production systems and comfort building a blameless post-incident review process.
• Working knowledge of SLOs and error budgets as a tool, not the job description; Nomad, Consul, or Vault experience is a strong plus.
• Strong programming skills in a language such as Python, Ruby, Java, or similar.

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.
