Job summary

IG Group is seeking a Senior Platform SRE to own and improve the reliability platform within a hybrid AWS/on-premises environment. The role focuses on observability, SLOs, and automated resilience across hundreds of services and engineers.

You will mentor others, drive incident prevention, and contribute to IG’s reliability standards. The position requires hands-on engineering, chaos testing, and strong collaboration with Platform Engineering and product teams in a fast-paced fintech setting.

Qualifications

• Hands-on observability and instrumentation with OpenTelemetry and production use of monitoring tools.
• Design and maintain SLOs, error budgets, and multi-window burn-rate alerts.
• Build and operate CI/CD pipelines with blue/green/canary releases and automated rollback.
• Experience with Kubernetes and Nomad in a hybrid cloud environment.
• Production-quality coding in Java and/or Python.
• Strong knowledge of distributed systems and failure modes.
• Experience with incident management and blameless post-incident reviews.
• Familiarity with chaos engineering practices and tooling.
• Ability to write RFCs and contribute to engineering standards.

Responsibilities

• Build and own the reliability platform and tooling.
• Implement comprehensive monitoring and observability across services.
• Maintain production readiness including automated deployments and zero-downtime patching.
• Design self-healing capabilities and automated traffic rerouting.
• Run chaos experiments to improve resilience and incident response.
• Develop CI/CD pipelines embedding reliability practices.
• Mentor engineers on reliability patterns and production engineering discipline.
• Collaborate with platform teams to define SLOs on customer journeys.

Job description

Job Title Senior Platform SRE Job Description So, who are we? IG is a FTSE 100 fintech operating across five continents, serving over 1.3m customers and handling billions of dollars in transactions – built on scale, trust, and proof. We didn't pivot to innovation; it's how we've always operated. What that means for the people who work here is real: genuinely complex problems to solve, the technology and resources to tackle them properly, and the kind of scope that's rare in established businesses. The bar is high – bring a curious and forward-thinking mindset and we'll give you the platform to define what comes next. Join us at IG – the future gets built here.

The Platform SRE team is the engine of IG’s reliability programme. We sit within Infrastructure & Operations, working across IG’s hybrid estate of on-premises HashiCorp Nomad and AWS. We are not a reactive ops team. We build the platform, standards, and tooling that make reliability the default for every engineering team at IG. Through the SRE Guild, we connect with Domain SREs and Reliability Champions across the organisation, setting the bar and lifting it together.

Your role in the Team's Success You will be a hands-on technical contributor at the heart of the Platform SRE team, owning pieces of the reliability platform that hundreds of engineers depend on. You will work at the intersection of software engineering, observability, and systems reliability, turning reliability from a reactive concern into a proactive engineering discipline. You will partner with Platform Engineering, product teams, and Reliability Champions to define what good looks like in production and then make it the default. You will contribute to the SRE Guild, mentor engineers across the organisation, and when things go wrong, you will be on the call helping to mitigate, understand, and prevent a repeat.

What you'll do

• 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, turning severe-but-plausible failure scenarios into engineering improvements
• Build automation tools and CI/CD pipelines that embed reliability practices, while applying software 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: SLO methodology, error budget policy, observability instrumentation guide, and Production 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.
• 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 (PIRs) within five working days using contributing-factor methodology
• Maintain the Lessons Register, track remediation actions to closure, and surface patterns across incidents quarterly

What you'll need for this role

• Observability and instrumentation: hands-on OpenTelemetry experience (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: proven track record designing 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; HashiCorp Nomad is a strong advantage on IG’s hybrid estate; solid understanding of cloud networking and IaC (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 record in 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 and eliminating manual toil
