Systems Infrastructure Engineer

TransFICC
London
Location: Remote First; office location Moorgate, London (flexible remote working locations within UK/Europe)
Employment type: Permanent
Working Hours: Full-time (9-5 UK)
Salary: Up to £110,000 + Shares + Benefits

TransFICC is hiring a Systems Infrastructure Engineer to provide high-performance services to our customers. We develop an integration service product that enables our clients to have a flexible, hosted service without requiring their internal resources to respond to connectivity challenges across trading venues.

You will be joining our SRE team and contributing to TransFICC's culture of automation. We are a multidisciplinary team covering all aspects of Linux, including physical data centre provisioning, AWS cloud, and networking infrastructure.

While you may be more of an expert in systems management (operating systems and hardware provisioning), we all share responsibility for the entire environment. You will also have the opportunity to learn and help manage the other areas our team is responsible for, including network infrastructure, identity management, security, and more. We are seeking someone like-minded who can contribute to our team while also learning from us.

About the Role - Your mission will be:
  • Building out the automated provisioning of TransFICCs servers and networks, both in physical environments and Cloud, i.e. AWS
  • Contributing to our first-class Infrastructure-As-Code ecosystem based on Ansible, Terraform and other high-level programming languages (e.g., Python, Bash)
  • Evolving our Continuous Delivery pipeline for provisioning servers and switches, and deploying software
  • Managing Linux builds and configuration across all physical and virtual hardware.
  • Interacting with hardware vendors, data centre hardware specialist teams, telecom providers, and financial institutions
  • Optimise hardware and software server builds for low-latency and high-performance trading activities.
  • Plan work in data centres.
What we are looking for:
  • Need to know how to code. You don't need to be an expert, but basic programming in your language of choice is required - you need to be able to build a program.
  • Everything we configure at TransFICC is automated, so having experience with a software automation tool like Ansible and coding ability is a must.
  • Holding a high degree of Linux administration is essential.
  • We are looking for someone experienced as a systems administrator; however, you must have a reasonable understanding of what is involved across systems, networks and security.
  • Constructive, open-minded and self-motivated. A belief in life learning, and an awareness of how much there still is to learn.
  • Appreciate autonomy and be able to take the initiative.
  • Experience managing 3rd parties via email and phone, negotiating with vendors, purchasing hardware and enabling remote work.
  • Ability to work with other teams, including developers, customer support and sales
Whilst not essential, it would be great if you had some of the following:
  • Authentication Protocols, i.e. SAML, OAuth2, OpenID, Kerberos
  • Microsoft/Azure Active Directory
  • Database HA - Clustering/replication, e.g. Postgres
  • Happy to provide desktop support when needed for MacOS, Windows and Linux laptops alike.
