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.

Your team

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 a pply ing 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 clos ing 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:

Extensive working experience in all the below mentioned areas.

Essential Technical Skills

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

We follow a hybrid working model with 3 days in the office - which we think balances the need to collaborate effectively and connect with each other.
