Job Information
Trexquant Investment Linux Systems Engineer (USA) in New York, New York
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.
