Position: Systems Administrator
Company: Optimal Market Technologies, LLC
Location: Chicago or NYC, hybrid
Salary: $140,000 - $200,000 base salary + discretionary bonus (commensurate with experience)

Position Overview:

We are seeking a hands-on Systems Administrator, working alongside our existing sysadmin, to keep our production infrastructure running and to grow it. You and your colleague own the infrastructure layer: hosts, network, storage, and connectivity, with some services supported by external providers. Application-level production support and incident coordination sit with our senior Production Engineer. You will build and operate what you put in place, automate routine work, and help us move from individual knowledge to reliable, documented systems.

Our environment:

We run an automated trading system with single-digit-millisecond latency requirements on bare-metal Linux. We use cloud for storage and are investigating wider use. We currently use Nagios and Ansible; our applications are written in C++, Python and SQL. We are actively modernizing, upgrading technologies (e.g. CentOS7 to RHEL9), and have legacy and new systems running in parallel. You will deliver a stream of technology changes.

Primary Responsibilities:

• Own the Linux and network estate across colocation and cloud: deployment, capacity, and failover.
• Automate routine work through Infrastructure as Code.
• Own infrastructure security: hardening, access control, recoverable backups, and security incident response.
