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 role in the Team
We're looking for a Senior Platform Engineer with deep Akamai expertise to own IG's edge delivery estate and change how it's run. Today, much of our Akamai configuration is managed by hand through Control Center. Your mandate is to move it into code: Terraform modules, version-controlled rule trees, and GitLab pipelines with the automated checks and guardrails that let application teams request and ship their own edge changes safely. You'll be the expert other engineers come to, and the person who steadily reduces how often they need to.

The Platform Team owns the infrastructure and automation platform underpinning IG's global trading operations - cloud-native infrastructure on AWS, GitLab CI/CD, and self-service capabilities that help development teams move faster with greater confidence. Edge delivery sits at the very front of that stack: every customer session, trade, and API call reaches IG through it, across every region we operate in and under latency-sensitive conditions.

You'll work hands-on with Property Manager and Akamai's rule tree model, Edge DNS and traffic management, edge security controls, and certificate lifecycle - from routine property changes through to incident diagnosis and long-term modernisation of the estate. If you care about content delivery and edge infrastructure, and want your work to have direct commercial and customer impact, we'd welcome your application.

What you'll do

• Automate the estate and enable self-service
• Lead the migration of Akamai configuration from manual Control Center changes to a Terraform-first workflow, building reusable, well-documented modules for properties, rule trees, and DNS that other teams can safely consume
• Build self-service paths for routine edge changes - new hostnames, redirects, caching rules - wrapped in policy checks, automated validation, and staging tests that catch mistakes before they reach production
• Integrate edge configuration into GitLab CI/CD alongside ServiceNow change control, so every property and DNS change is peer-reviewed, tested, and promoted through environments the same way each time
• Build tooling around Akamai's APIs (Python, Bash) that removes repetitive operational work - bulk changes, certificate expiry checks, drift detection, and inventory reporting
• Own the design, configuration, and operational health of IG's Akamai estate across staging and production networks, in line with change control
• Design and maintain URL redirection, rewrite, and forwarding logic - 301/302, host- and path-based, and Cloudlet-driven - across IG's public and internal domains, rationalising inherited redirect chains as you go
• Configure routing and origin behaviour, including edge hostnames, CP codes, conditional and dynamic origin selection, failover, and load balancing to support multi-origin, multi-region delivery
• Set caching and delivery strategy - compression, HTTP/2 and HTTP/3, image and video delivery, API acceleration - and run purge and cache invalidation workflows that support release and incident response
• Support multi-CDN and failover strategy through Global Traffic Management, and contribute to disaster recovery and resilience planning for edge delivery
• Configure and tune edge security controls - Site Shield, network lists and IP allow-listing, WAF, and bot mitigation - as traffic patterns and threats evolve
• Manage the SSL/TLS certificate lifecycle for edge properties in coordination with Venafi, ensuring certificates reach the edge well ahead of expiry
• Maintain an auditable inventory of properties, hostnames, certificates, and CP codes, and lead periodic reviews that surface and remediate configuration drift and stale entries
• Diagnose complex delivery, routing, and performance incidents using Edge Diagnostics, debug and pragma headers, mPulse, and reporting APIs - tracing an issue from DNS resolution through edge and origin behaviour to root cause, then closing the gap that allowed it
• Partner with Platform Managers and application teams to translate hosting and delivery requirements into configuration that is secure, performant, and maintainable, and spread edge knowledge across the wider platform organisation

What you'll need
Experience level: 5+ years in CDN and e
