Description

We are seeking a hands-on IT Infrastructure Engineer to join our London office. This role is responsible for supporting and evolving the core infrastructure that underpins our production systems, as well as development and research platforms.

We are looking for someone with a modern, automation-focused mindset who is comfortable operating in business-critical environments. You will play a key role not only in maintaining stability and resilience, but also in improving and modernising our infrastructure practices over time.

Key Responsibilities

Primary Duties

Implement and support Infrastructure-as-Code using tools such as Terraform and Ansible
Write and maintain scripts (Bash, Python) to automate operational tasks and reduce manual processes
Identify opportunities to modernise and optimise infrastructure and operational processes
Work closely with Managed Service Providers (MSPs) and internal stakeholders
Administer and manage NFSv4 file systems
Administer and support Red Hat Enterprise Linux (RHEL) servers in a production environment
Contribute to Disaster Recovery planning, testing, and continuous improvement
Maintain and improve monitoring, logging, and alerting systems
Investigate and remediate Cyber security alerts from our suite of monitoring tools
Contribute to infrastructure hardening and security best practices

Technical stack & tools

Strong hands-on experience administering RHEL in production environments
Experience managing on-premise physical hardware infrastructure
Strong scripting skills in Bash and/or Python
Experience with automation and configuration management tools (e.g., Ansible)
Experience implementing or working with Terraform or other Infrastructure-as-Code tooling
Solid understanding of Disaster Recovery principles and testing
Proven experience administering NFSv4 file systems
Experience working alongside or managing Managed Service Providers (MSPs)
Good understanding of infrastructure security fundamentals and system hardening
Experience working within a financial services firm or similarly regulated environment

Skills, Knowledge and Expertise

Experience, Knowledge & Skills

5+ years infrastructure experience.
A pragmatic, hands-on infrastructure engineer who enjoys solving complex technical problems.
An automation-first mindset, with a drive to eliminate repetitive manual tasks.
Strong sense of ownership and operational discipline.
Comfortable challenging legacy processes and proposing modern alternatives.
Continuous improvement mentality with a focus on reliability and efficiency.
Good systems thinking and architectural awareness beyond individual servers.
Ability to work independently while collaborating across technical teams.
Clear communication skills and ability to engage with both technical and non-technical stakeholders.

Desirable

Active Directory administration
Pure Storage (Pure SAN)
Microsoft Azure and/or AWS
HashiCorp stack (Vault, Consul, Nomad)
VMware
Docker and/or Kubernetes
Exposure to vulnerability management or security auditing practice

Educational & Professional Qualifications

Educated to degree (or equivalent) level or higher, preferably from a leading university.
A degree with some mathematical and/or computing content.
Professional certifications are not required but relevant training or certifications are a plus.

Benefits

Systematica Investments provides you with excellent benefits from day 1. We provide private medical insurance for you and your immediate family.
