Build and own the reliability platform

• Implement comprehensive monitoring and observability usingOpenTelemetryand distributed tracingMaintain SLO, error budgetsand burn-rate tracking

• Establish andmaintain24/7 operational readiness including automated deployments, blue/green releases, and zero-downtime patching strategies

• Engineer self-healing capabilities: auto-remediation, error-budget-gated rollback, and automated traffic rerouting

• Design and run chaos experiments across the AWS estate, turning severe-but-plausible failure scenarios into engineering improvements

• Build automation tools and CI/CD pipelines that embed reliability practices, whileapplyingsoftware engineering discipline including version control, code reviews, and testing

• Contribute to the SRE AI agent, IG’s agentic tooling for incident investigation and reliability review, built on AWS frontier models

• Mentor junior SREs and Reliability Champions on reliability patterns and production engineering discipline

Set and uphold standards

• Author and evolve the SRE standards that underpin the Guild: SLOmethodology, error budget policy, observability instrumentation guide, andProduction Readiness Review(PRR)checklist

• Mentor developers on reliability patterns including circuit breakers, retry logic, and fault tolerance

• Work with development teams and Reliability Champions to design SLOs on customer journeys rather than per-service

• Assistand guide teamsin system design, capacity planning,architecturalreviewsandclosingobservability gaps

Own incident response and learning

• Facilitate blameless post-incident reviews (PIRs) within five working days using contributing-factormethodology

• Maintain the Lessons Register, track remediation actions to closure, and surface patterns across incidents quarterly

What you'll need for this role:

Extensive working experience in all the below mentioned areas.

Essential Technical Skills

• Observability and instrumentation:hands-onOpenTelemetryexperience (spans, metrics, traces, context propagation) and production use of Honeycomb, Datadog, Dynatrace, or Grafana; able to instrument Java or Python services directly

• SLOs and error budgets:proventrack recorddesigning customer-meaningful SLIs, setting error budgets, configuring multi-window burn-rate alerts, and working with development teams on reliability measurement

• CI/CD and release engineering:experience building pipelines with safety mechanisms: blue/green and canary releases, automated rollback, and DORA metrics integration

• Container orchestration:Kubernetes (EKS, AKS, or GKE)required;HashiCorpNomad is a strong advantage on IG’s hybrid estate; solid understanding of cloud networking andIaC(Terraform preferred)

• Software engineering:production-quality coding in Java and/or Python; comfortable contributing to application codebases to implement reliability patterns, not just configuring infrastructure around them

• Distributed systems:strong understanding of how large-scale systems fail and how to make them fail safely; circuit breakers, bulkheads, idempotency, graceful degradation, and load-shedding; high-throughput, low-latency environments preferred

• Incident management:on-call experience on production systems, blameless PIR facilitation, contributing-factor analysis, and driving action items to closure; PagerDuty and ServiceNow familiarity helpful

• Chaos engineering:experience designing and executing hypothesis-driven experiments with blast-radius controls and gap-to-impact-tolerance analysis; AWS FIS, Gremlin, or equivalent

• Community and standards:at ease in a guild or community-of-practice model; comfortable writing RFCs, presenting at engineering forums, and building standards that others will adopt

Experience Requirements

• Track recordin high-throughput, production environments (financial services, trading platforms, or similar mission-critical systems preferred)

• Demonstrated ability to improve system reliability and performance at scale

• Experience working collaboratively with development teams to implement observability and reliability improvements

• Strong troubleshooting skills in distributed systems environments

Core Competencies

• Systems thinking approach to problem-solving

• Excellent communication skills for cross-functional collaboration and technical enablement

• Ability to balance hands-on development work with operational responsibilities

• Strong bias toward automation andeliminatingmanual toil
