Aspect Capital is an award-winning systematic hedge fund based in London that manages over $9 billion of client assets. Technology plays a critical role in the success of our business. Our team supports a diverse technology estate spanning Linux and Microsoft platforms, virtualisation, networking, storage, cloud services and automation tooling.

The Role: We are looking for a Systems Administrator to join our Infrastructure team.

Key Responsibilities:

  • Supporting Linux systems and infrastructure services across a mixed Linux (Ubuntu and RHEL) and Microsoft environment
  • Assisting with the deployment, maintenance and improvement of servers and infrastructure services
  • Troubleshooting system, application, performance and availability issues
  • Working with automation and configuration management tooling
  • Supporting virtualisation, storage, networking and cloud-based services
  • Contributing to documentation, monitoring and operational best practices

Requirements: Essential:

  • 2-5 years' experience supporting production infrastructure environments
  • Good Linux administration skills, including services, networking, permissions, filesystems and logging
  • Experience working in mixed Linux and Microsoft environments
  • Experience supporting physical, virtual or cloud-based infrastructure
  • Familiarity with Active Directory, DNS, DHCP and authentication services
  • Experience with scripting or automation using Bash, PowerShell or Python

Desirable:

  • Experience with configuration management or automation tooling such as Puppet, Ansible or similar
  • Exposure to AWS or other cloud platforms
  • Familiarity with Active Directory-integrated Linux environments
  • Experience with tools such as TeamCity, Jenkins, Artifactory, Git, Docker, Grafana, Terraform or Kubernetes would be beneficial but is not required.

If this sounds like a role you’d be interested in, we would love to hear from you. No agencies, please.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
