Jobbeschreibung

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
• Competitive salary with performance‑based bonus
• Collaborative, team‑oriented work environment
• PPO health, dental, and vision insurance fully covered for employees and dependents
• 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.
