Role
Who you are
- 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
- 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
- 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
What the job involves
- 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
- 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
- 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
- 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

Our take
Founded in 1974 by Stuart Wheeler as a UK-based spread betting company for gold, IG Group, abbreviated from Investors Gold Index, was initially set up to allow people to speculate and trade on the price change of gold without owning physical gold. And in the year 2000, it was listed on the London Stock Exchange and its gradual evolution into the world of fintech began.
By 2011, the company had played a part in numerous international buyouts before narrowing its focus down to financial wagers. During the latter half of that decade, IG shut down its binary options trading platform and focused instead on building an investment portfolio with partner BlackRock Investments, all whilst maintaining its Forex and CFD trading processes. Since then, it has become a fast-paced market leader in the investment space.
In recent years, IG Group has developed major platforms for various trading actions and has grown profit and revenue significantly. Alongside this it has acquired a number of companies, including tastytrade and Freetrade, and launched its own crypto product, making it the first UK-listed company to launch crypto trading to retail investors. This further proves how much of a staple IG Group is in the world of financial trading.
