Location: Hybrid in London office
Start Date: ASAP
Duration: 3 months (extension after)
Daily Rate: £300 - £400 per day outside IR35
Summary of what we’re looking for
  • We need someone who is excellent with people, stays calm under pressure, pays close attention to detail, and has the judgment to know when to escalate and when to act independently.
  • The role is predominantly support-facing, serving internal teams including developers, traders, and operations.
  • Think of it as an internal client-facing role with a technical infrastructure backdrop.
Key Skills
  • 3 years in a Platform Support Engineer, DevOps, or similar role
  • A track record of delivering high-quality support to internal or external clients, with strong communication and responsiveness.
  • Experience working in financial services is preferred but not required.
  • AWS, Ansible, Terraform, GitLab CI, Linux are the core technical areas.
  • Strong knowledge of AWS (equivalent to AWS Associate Certification level) across a multi-account, multi-region environment.
  • Proficiency in Terraform and Ansible for infrastructure and server management.
  • Experience with Docker or managing EKS clusters and containerised applications.
  • Experience supporting CI/CD pipelines, ideally with GitLab CI.
  • Strong understanding of Linux systems, including diagnosing and resolving common issues.
  • Familiarity with observability tools such as Prometheus, Grafana, and OpenSearch.
  • Good understanding of networking concepts, including connectivity, latency, and routing.
  • Knowledge of cloud and network security principles.
  • Strong troubleshooting and problem-solving skills, with a natural curiosity for understanding root causes.
  • Ability to communicate technical concepts clearly to non-technical users.
  • The team uses Teleport as its primary identity and access management platform. Prior experience is not required, but candidates should be comfortable picking it up quickly.
Responsibilities
  • Serve as the primary point of contact for infrastructure-related support requests, building strong working relationships with teams across the business.
  • Respond to Slack and support queue requests promptly, taking time to understand each request fully before acting and keeping users informed of progress and timelines throughout.
  • Maintain clear and up-to-date ticket records so that the team always has visibility of what is in flight.
  • Work within agreed SLAs and help users understand what to expect and when, including when a request needs to be prioritised, routed to another team, or scheduled.
  • Bring a security-conscious mindset to every request, understanding when to proceed independently, when to involve the security team, and when compliance or operational constraints apply.
  • Build user confidence in the support function by being reliable, transparent, and easy to work with.
  • Troubleshoot and resolve issues related to infrastructure, applications, and configurations, ensuring minimal downtime.
  • Promote self-service solutions and help users help themselves where possible, reducing repetitive requests over time.
  • Support and manage infrastructure in AWS, including EC2, S3, IAM, EKS, and VPCs.
  • Configure and manage servers using Ansible for operational consistency.
  • Use Terraform to manage infrastructure changes and resolve support-related issues.
  • Support CI/CD pipelines and assist teams with pipeline-related issues using GitLab CI.
  • Support hybrid infrastructure, including workloads in AWS and physical servers in data centres near exchanges.
  • Participate in the out-of-hours support rota, ensuring business continuity.
  • Maintain and update documentation to support repeatable, high-quality service delivery.
  • Leverage AI-assisted development tools productively while applying sound engineering judgment to all outputs.
  • Work in a non-tiered support model where any incident may go to any engineer on call.
  • Develop broad exposure to the infrastructure estate while operating within agreed runbooks for production systems.
