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.\nThe bar is high - bring a curious and forward-thinking mindset and we'll give you the platform to define what comes next.\nJoin us at IG - the future gets built here.\nYour team\nThe 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.\nWe 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.\nYour role in the Team's Success\nYou 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.\nYou 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.\nWhat you'll do\nBuild and own the reliability platform\nImplement comprehensive monitoring and observability using OpenTelemetry and distributed tracing. Maintain SLO, error budgets and burn-rate tracking \nEstablish and maintain 24/7 operational readiness including automated deployments, blue/green releases, and zero-downtime patching strategies \nEngineer self-healing capabilities: auto-remediation, error-budget-gated rollback, and automated traffic rerouting \nDesign and run chaos experiments across the AWS estate, turning severe-but-plausible failure scenarios into engineering improvements \nBuild automation tools and CI/CD pipelines that embed reliability practices, while applying software engineering discipline including version control, code reviews, and testing. \nContribute to the SRE AI agent, IG’s agentic tooling for incident investigation and reliability review, built on AWS frontier models \nMentor junior SREs and Reliability Champions on reliability patterns and production engineering discipline \nSet and uphold standards\nAuthor and evolve the SRE standards that underpin the Guild: SLO methodology, error budget policy, observability instrumentation guide, and Production Readiness Review (PRR) checklist \nMentor developers on reliability patterns including circuit breakers, retry logic, and fault tolerance \nWork with development teams and Reliability Champions to design SLOs on customer journeys rather than per-service. \nAssist and guide teams in system design, capacity planning, architectural reviews and closing observability gaps. \nOwn incident response and learning\nFacilitate blameless post-incident reviews (PIRs) within five working days using contributing-factor methodology \nMaintain the Lessons Register, track remediation actions to closure, and surface patterns across incidents quarterly \nWhat you'll need for this role:\nExtensive working experience in all the below mentioned areas.\nEssential Technical Skills\n 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. \nSLOs 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 \nCI/CD and release engineering: experience building pipelines with safety mechanisms: blue/green and canary releases, automated rollback, and DORA metrics integration \n 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) \nSoftware engineering: production-quality coding in Java and/or Python; comfortable contributing to application codebases to implement reliability patterns, not just configuring infrastructure around them \nDistributed 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 \nIncident management: on-call experience on production systems, blameless PIR facilitation, contributing-factor analysis, and driving action items to closure; PagerDuty and ServiceNow familiarity helpful \nChaos engineering: experience designing and executing hypothesis-driven experiments with blast-radius controls and gap-to-impact-tolerance analysis; AWS FIS, Gremlin, or equivalent \nCommunity 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 \nExperience Requirements\nTrack record in high-throughput, production environments (financial services, trading platforms, or similar mission-critical systems preferred) \nDemonstrated ability to improve system reliability and performance at scale \nExperience working collaboratively with development teams to implement observability and reliability improvements \nStrong troubleshooting skills in distributed systems environments \nCore Competencies\nSystems thinking approach to problem-solving \nExcellent communication skills for cross-functional collaboration and technical enablement \nAbility to balance hands-on development work with operational responsibilities \nStrong bias toward automation and eliminating manual toil \nThe Perks\nYour growth fuels our success! Thrive with tailored development programs, mentoring opportunities with leaders, and clear career progression. Expand your network through committees, sports and social clubs. Enjoy extra time off for volunteering and community work.\nCompetitive salary\nFlexible Benefits Package on top of your salary (12%)\nPrivate medical cover for you and your family\nLife insurance\nContribution to gym memberships\n25 Days holiday, with 1 additional day off to celebrate your Birthday & 2 additional days off a year for voluntary work (28 in total\nThe option to buy or sell holiday days.\nUnlimited access to the LinkedIn Learning Platform\nA comprehensive global and local onboarding process\nEmployee-led LGBTQ+, Women’s, Black and Parents & Carers networks with an annual budget for organising events & projects that foster an open, diverse and inclusive culture\nEnhanced primary (maternity), secondary (paternity), and shared parental pay and leave, as well as a range of support and benefits for parents\nOption to participate and create ESG initiatives based on IG Brighter Future Fund\nLearn more about the Perks here!\nJoin us for this exciting journey.
