Your role requires quick assessment, triage and resolutions of technical issues impacting our environment. You’ll have the opportunity to develop a range of tools used for monitoring, real-time trade analysis, and job management. Furthermore, our technology framework continues expanding and changing, introducing top of the line, dynamic technologies. All of this offers you an opportunity to enhance your technical expertise and project management skills through collaboration with development and engineering staff across the firm and our technology organization as well as through the learning opportunities exposure to such technologies can provide.

In this role, you will:

  • Support and maintain Windows and Linux server processes and the internally developed application services that run on them
  • Monitor and support a highly distributed production system
  • Work directly with application teams and other stakeholders to understand their needs and generate practical solutions
  • Build automation using AI tools to reduce manual operational work and speed up incident response
  • Have the autonomy to seek out and implement process optimization opportunities in support of business and technical users

What we’re looking for

  • 2-5 years of experience in an operations, systems administration, or application support related role
  • Demonstrated experience with Linux and Windows environments and a solid understanding of how multitiered systems work
  • Scripting experience with Python, PowerShell, and/or Bash to automate tasks, build tooling, and simplify repetitive work
  • Working familiarity with Kafka, MariaDB, MongoDB, InfluxDB, and ELK sufficient to support and troubleshoot production environments
  • Working knowledge of networking fundamentals
