Job description

We are seeking a hands‑on Linux Systems Engineer to build, maintain, and scale our on‑premise infrastructure. This role is focused on bare‑metal Linux systems, with significant ownership across server provisioning, storage, and system reliability.

The ideal candidate is detail‑oriented, highly disciplined, and comfortable operating in a demanding, production‑critical environment. This is not a cloud‑focused role—success requires deep experience with physical infrastructure, Linux internals, and automation in a high‑performance setting.

Responsibilities

• Build, provision, and maintain bare‑metal Linux servers, including OS installation, configuration, and lifecycle management
• Own server infrastructure from hardware through operating system and core services, ensuring stability and performance
• Configure and manage storage systems, including ZFS and enterprise storage platforms (e.g., NetApp, Dell, or similar)
• Monitor system health and performance; troubleshoot issues and implement durable, long‑term fixes
• Develop and maintain automation using Ansible and Bash to standardize provisioning, configuration, and operations
• Perform system patching, upgrades, and capacity planning across a growing server fleet
• Participate in incident response, root cause analysis, and continuous improvement of system reliability
• Collaborate with engineering and infrastructure teams to support application performance on Linux systems
• Contribute to documentation, runbooks, and operational best practices
• Support data center operations as needed, including hardware troubleshooting, racking, cabling, and server replacements
• Travel to data centers periodically for maintenance, expansions, and issue resolution

Requirements

• Bachelor's degree in a technical field or equivalent practical experience
• 3+ years of experience managing Linux systems in a production environment
• Strong expertise in Linux at the system level, including OS installation, configuration, and troubleshooting on bare metal
• Proven experience provisioning and managing physical servers at scale (100+ servers preferred)
• Hands‑on experience with storage systems, including ZFS; familiarity with enterprise storage vendors (NetApp, Dell, or similar) is strongly preferred
• Proficiency with Ansible for configuration management and automation (required)
• Strong Bash scripting skills; Python is a plus but not required
• Solid understanding of system performance, resource management, and reliability in production environments
• Experience working in environments where uptime, precision, and operational discipline are critical
• Willingness to perform occasional hands‑on hardware work and travel to data centers as needed
• Ability to participate in an on‑call rotation

Benefits

• Competitive salary with performance‑based bonus
• Collaborative, team‑oriented work environment
• PPO health, dental, and vision insurance fully covered for employees and dependents
• Pre‑tax commuter benefits
• Weekly company‑sponsored meals

Applications are open for both Stamford and New York City offices, the latter with a planned opening in October 2026.

The base salary for this role is $130,000 - $150,000, and will be determined based on the candidate's educational background and professional experience. Base salary is one component of Trexquant's total compensation package, which may also include a discretionary, performance‑based bonus. This position is classified as overtime‑exempt.
