Job Description

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 edge delivery and routing

  • 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

Secure and govern the edge

  • 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, partner, and share

  • 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 edge delivery engineering, with deep hands-on Akamai expertise and a strong infrastructure-as-code background.

  • Deep Akamai expertise - property creation, versioning, rule tree configuration, and activation across staging and production via Property Manager (Control Center and PAPI), with the judgement to know which logic belongs at the edge and which doesn't
  • Automation and infrastructure-as-code - hands-on with the Akamai Terraform Provider, writing reusable modules that others actually adopt; GitLab CI/CD pipeline experience; and scripting in Python or Bash to automate against vendor APIs
  • Routing, DNS, and traffic management - edge hostnames, CP codes, origin and failover behaviour, conditional origins, and traffic steering, with working knowledge of Edge DNS and/or Global Traffic Management for resolution, load balancing, and multi-region routing
  • Redirection and rewrite strategy - host- and path-based redirects, rewrites, and Cloudlet policies (Edge Redirector, Forward Rewrite, Visitor Prioritization), including untangling legacy redirect logic without breaking live traffic
  • Edge security and certificates - Site Shield, network lists, WAF and bot mitigation, plus SSL/TLS certificate lifecycle management (ideally with Venafi) and a solid grasp of certificate chains, SNI, and secure delivery requirements
  • Troubleshooting and delivery observability - Edge Diagnostics, debug headers, mPulse (RUM), and traffic reporting APIs, backed by strong network fundamentals (TCP/IP, DNS, HTTP/HTTPS, routing) and a clear picture of how DNS, CDN, origin, and application layers interact under production load
  • Delivering change in a controlled environment - experience working through formal ITSM/change-control processes such as ServiceNow, in regulated or high-availability settings

Company Benefits

  • Competitive salary
  • Flexible Benefits Package on top of your salary (x%)
  • Private medical cover for you and your family
  • Life insurance
  • Contribution to gym memberships
  • 25 Days holiday, with 1 additional day off to celebrate your Birthday & 2 additional days off a year for voluntary work (28 in total)
  • The option to buy or sell holiday days
  • Unlimited access to the LinkedIn Learning Platform
  • A comprehensive global and local onboarding process
  • Employee-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
  • Option to participate and create ESG initiatives based on IG Brighter Future Fund

Job Description

Starling is the UK’s first and leading digital bank on a mission to fix banking! Our vision is fast technology, fair service, and honest values. All at the tap of a phone, all the time.

Our technologists are at the very heart of Starling and enjoy working in a fast-paced environment that is all about building things, creating new stuff, and disruptive technology that keeps us on the cutting edge of fintech. We operate a flat structure to empower you to make decisions regardless of what your primary responsibilities may be, innovation and collaboration will be at the core of everything you do. Help is never far away in our open culture, you will find support in your team and from across the business, we are in this together!

The way to thrive and shine within Starling is to be a self-driven individual and be able to take full ownership of everything around you: From building things, designing, discovering, to sharing knowledge with your colleagues and making sure all processes are efficient and productive to deliver the best possible results for our customers. Our purpose is underpinned by five Starling values: Listen, Keep It Simple, Do The Right Thing, Own It, and Aim For Greatness.

Hybrid Working

We have a Hybrid approach to working here at Starling - our preference is that you're located within a commutable distance of one of our offices so that we're able to interact and collaborate in person. We don't like to mandate how much you visit the office and work from home, that's to be agreed upon between you and your manager.

Our Data Environment

Our Data teams are excited about the value of data within the business, powers our product decisions to improve things for our customers and enhance effective and agile decision making, regardless of what their primary tech stack may be.

Requirements

We have built our entire banking platform in house and mostly in Java. We are looking for people who want to work on building the tooling that is used by our engineers on a daily basis.

We are looking for people who are truly full stack, and are as comfortable polishing their javascript front end as they are debugging the innards of their java applications database interactions, or standing up infrastructure with terraform. We are looking for people who can:

  • Design REST apis.
  • Code backend services, ideally using Java, or another other server side compiled language.
  • Develop modern front ends, ideally using React and Redux.
  • Get their code into the cloud and support it there, ideally on AWS.
