What is a systems engineer?

Systems engineers are professionals who design, integrate, and manage complex systems throughout their life cycles. They work across various industries, ensuring that all aspects of a project or system—hardware, software, processes, and people—work together efficiently and effectively. Systems engineers coordinate between different engineering teams, address technical and organizational challenges, and ensure requirements are met. Their role often involves both big-picture thinking and attention to detail to deliver reliable and scalable solutions.

What does a systems engineer do?

The role of a systems engineer varies based on the company they work for, but in every industry systems engineers use computerized systems to keep track of all the moving parts within their organizations. The term systems engineer usually refers to a computer systems engineer, which combines several disciplines to create, purchase, and install a computer system that suits the needs of each particular client. They will also work in a hands-on manner during the installation, acquisition, testing, and implementation phases of the project. Duties typically include making recommendations for scalability, troubleshooting any problems that arise during the use of the system, reviewing a company’s security requirements, and recommending security measures to allow the company to avoid compromising any sensitive data.

What is the difference between Systems Engineer vs Network Engineer?

AspectSystems EngineerNetwork Engineer

Work EnvironmentDesigning, implementing, and managing IT systems and infrastructureDesigning, configuring, and maintaining network hardware and connectivity
Industry UsageIT, technology, enterprise solutionsTelecommunications, IT, networking service providers
Common TasksSystem integration, troubleshooting, server managementNetwork setup, routing, switching, security

While both roles involve technical expertise in IT infrastructure, Systems Engineers focus on overall system architecture and integration, whereas Network Engineers specialize in network hardware, connectivity, and security. Understanding these differences helps employers and professionals align skills with job requirements.

What are the key skills and qualifications needed to thrive as a systems engineer, and why are they important?

To thrive as a Systems Engineer, you need a strong background in systems architecture, troubleshooting, and integration, typically supported by a degree in computer science or engineering. Familiarity with operating systems (like Linux and Windows), virtualization platforms, scripting languages, and certifications such as CompTIA, Cisco (CCNA), or Microsoft (MCSA) are commonly required. Strong problem-solving abilities, effective communication, and teamwork make candidates stand out in this role. These skills and qualifications ensure the design, implementation, and maintenance of reliable, scalable systems critical for organizational operations.

How does a systems engineer typically collaborate with cross-functional teams during a project lifecycle?

Systems Engineers often serve as a bridge between various technical and non-technical teams, including software developers, network specialists, project managers, and end users. Throughout a project, they participate in requirements gathering, design reviews, and integration testing, ensuring that each component fits seamlessly within the overall system. Effective communication and documentation are crucial, as Systems Engineers must translate complex technical concepts into actionable tasks for diverse stakeholders. This collaborative approach not only streamlines problem-solving but also helps deliver robust, scalable solutions.

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.

Trexquant is an Equal Opportunity Employer
