Senior Platform SRE

IG is a FTSE 100 fintech operating across five continents, serving over 1.3 million customers and handling billions of dollars in transactions. The Platform SRE team is part of Infrastructure & Operations working across a hybrid estate of on-premises HashiCorp Nomad and AWS, responsible for reliability programs at IG.

• 6+ years of experience including:
• Hands-on OpenTelemetry experience with spans, metrics, traces, context propagation; production use of Honeycomb, Datadog, Dynatrace, or Grafana; ability to instrument Java or Python services.
• Proven track record designing customer-meaningful SLIs, error budgets, multi-window burn-rate alerts, and working with teams on reliability measurement.
• Experience building CI/CD pipelines with safety mechanisms like blue/green and canary releases, automated rollback, and DORA metrics integration.
• Container orchestration experience with Kubernetes (EKS, AKS, or GKE) required; HashiCorp Nomad is a strong advantage; solid understanding of cloud networking and Infrastructure as Code (Terraform preferred).
• Production-quality coding in Java and/or Python with ability to implement reliability patterns in application code.
• Strong understanding of distributed systems failure modes, circuit breakers, bulkheads, idempotency, graceful degradation, load-shedding; preferably in high-throughput, low-latency environments.
• Incident management experience with on-call duties, blameless PIR facilitation, contributing-factor analysis; familiarity with PagerDuty and ServiceNow.
• Experience designing and executing chaos engineering experiments with blast-radius controls; familiarity with AWS FIS, Gremlin or equivalents.
• Comfortable working in guild or community-of-practice model, writing RFCs, presenting at forums, and building adoptable standards.
• Track record in high-throughput production environments, preferably financial services or trading platforms.
• Strong troubleshooting skills in distributed systems.

Core Competencies:

• Systems thinking approach.
• Excellent communication skills for cross-functional collaboration.
• Ability to balance development and operational responsibilities.
• Strong bias toward automation and eliminating manual toil.

Build and own the reliability platform:

• Implement comprehensive monitoring and observability using OpenTelemetry and distributed tracing.
• Maintain SLO, error budgets and burn-rate tracking.
• Establish and maintain 24/7 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.
• Build automation tools and CI/CD pipelines embedding reliability practices and software engineering discipline.
• Contribute to the SRE AI agent built on AWS frontier models.
• Mentor junior SREs and Reliability Champions on reliability and production engineering discipline.

Set and uphold standards:

• Author and evolve SRE standards including SLO methodology, error budget policy, observability instrumentation guide, and Production Readiness Review checklist.
• Mentor developers on reliability patterns such as circuit breakers, retry logic, and fault tolerance.
• Work with development teams and Reliability Champions to design SLOs on customer journeys.
• Assist and guide teams in system design, capacity planning, architectural reviews, and closing observability gaps.

Own incident response and learning:

• Facilitate blameless post-incident reviews using contributing-factor methodology within five working days.
• Maintain the Lessons Register, track remediation actions to closure, and surface patterns across incidents quarterly.
