What is a senior systems engineer?

A senior systems engineer is an IT (information technology) professional tasked with designing and maintaining network systems and security. Examples include large server or storage systems, computer networks, and mainframes. As a systems engineer, your primary duties are to oversee the daily operations of your facility and lead a team of engineers in designing new systems to replace old ones. You may work for a company that provides engineering services and solutions for other businesses, or you may be part of a large university or other institution's IT department. Skills needed for the career include the ability to work independently, leadership, and analytical problem-solving. A bachelor’s degree in electrical engineering or IT and significant experience in a lower systems engineering position are essential qualifications.

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

To thrive as a Senior Systems Engineer, you need expertise in systems architecture, troubleshooting, and network administration, typically supported by a degree in computer science or a related field and several years of relevant experience. Familiarity with virtualization platforms, cloud services (like AWS or Azure), automation tools (such as Ansible or PowerShell), and certifications like CompTIA, Microsoft, or Cisco are often required. Outstanding problem-solving, communication, and project management skills help you lead initiatives and collaborate effectively across teams. These competencies are crucial for ensuring system reliability, scalability, and security in complex IT environments.

What are some common challenges faced by senior systems engineers when integrating new technologies into existing infrastructure?

Senior Systems Engineers often encounter challenges such as ensuring compatibility between legacy systems and new technologies, minimizing downtime during migrations, and addressing unforeseen security vulnerabilities. Effective integration requires thorough planning, cross-team collaboration, and detailed testing to avoid disruptions to business operations. Staying current with emerging technologies and adopting best practices for change management are essential for overcoming these challenges and ensuring smooth implementation.

What is the difference between Senior Systems Engineer vs Systems Administrator?

AspectSenior Systems EngineerSystems Administrator
CertificationsCompTIA Security+, Cisco CCNA, Microsoft certificationsCompTIA A+, Network+, Microsoft certifications
Work EnvironmentDesigning, implementing, and troubleshooting complex systemsManaging daily system operations and user support
Industry UsageIT, technology, enterprise environmentsIT support, small to medium businesses

While both roles involve working with IT systems, Senior Systems Engineers focus on designing and implementing complex infrastructure, whereas Systems Administrators handle routine maintenance and user support. The senior role typically requires more advanced certifications and experience, and often involves strategic planning and system architecture.

Job description

Aquatic was founded with a shared passion for tackling some of the most complex challenges in one of the world's most competitive arenas-global financial markets. From the very beginning, we have been driven by a deep commitment to applying cutting-edge scientific research and technological innovation to deliver unparalleled performance. Our journey is one of continuous growth and exploration, marked by a spirit of curiosity and relentless drive for excellence.
Aquatic Capital Management is seeking a Systems Engineer to join our team.
Systems Engineer
Infrastructure & Research Computing
Aquatic Capital Management • Chicago, IL • Full-Time
About the Role
  • We are hiring a Systems Engineer to join our Infrastructure team. This is a senior individual contributor role with significant architectural ownership, and real accountability for how our research and trading systems compute.
  • You will own and evolve the compute infrastructure that powers quantitative research and production trading at Aquatic: our on-premise grid, hybrid cloud compute (GCP and AWS), GPU workloads, storage systems, and the automation that ties it all together.

What You Will Do
Grid & High-Performance Computing
  • Own and evolve Aquatic's Slurm and Ray cluster infrastructure across on-prem and GCP - supporting research and trading workloads including fitting, tuning, backtesting, feature computation, and market data processing.
  • Drive architectural improvements to capacity, scheduling efficiency, and throughput across the full footprint, including GPU computation.
  • Design and maintain the connectivity and automation between on-prem and cloud environments
  • Evaluate and implement newer compute paradigms as research needs evolve

Storage & Performance
  • Own high-performance storage systems including VAST (NFS and S3-compatible), ensuring data access is fast and reliable across research, trading, and build workloads.
  • Investigate and resolve performance bottlenecks at the intersection of storage, network, and compute.

Developer Experience & Automation
  • Design and maintain provisioning systems for complex compute resources and datacenter onboarding.
  • Own and improve CI/CD infrastructure (GitHub Actions) as well as the development toolchain for the broader engineering organization.

Technical Leadership & Mentorship
  • Serve as the go-to architect for infrastructure decisions; provide technical direction and help establish vision across the team.
  • Pair with and mentor earlier-career Systems & Software Engineers, helping them develop sound instincts and grow their skills.
  • Diagnose and resolve the hardest, most obscure system issues that others cannot get to the bottom of.

What We Are Looking For
Required
  • 10+ years of experience in systems engineering, infrastructure, or a closely related discipline.
  • Deep Unix/Linux expertise across multiple distributions; comfortable at every layer of the stack.
  • Strong experience with HPC grid systems (SLURM preferred) in a research or scientific computing environment.
  • Experience provisioning and managing bare-metal infrastructure and data centers, not just cloud-native environments.
  • Familiarity with high-performance / parallel storage systems (VAST, GPFS, Lustre, or similar).
  • Strong scripting and automation fluency (Bash, Python, or similar); able to build tools that others rely on and to contribute to and own production codebases.
  • Ability to operate as an independent technical leader: establishing direction, building trusted relationships, and communicating clearly with stakeholders outside the team.

Strongly Preferred
  • Experience with distributed compute frameworks such as Ray, Dask, or Spark in a research context.
  • Low-level systems programming on Linux using C/C++, with a focus on performance and reliability.
  • Experience with GPU computation and instrumenting GPU utilization for ML/research workloads.
  • Hands-on experience building and operating cloud infrastructure on GCP (or comparable major cloud), including autoscaling compute clusters.
  • Strong networking fundamentals; able to design and troubleshoot complex network topologies including cloud interconnects.
  • Background working alongside quantitative researchers or software engineers in a trading, finance, or research-intensive organization.

What Makes You Stand Out
  • You have an architectural mindset: you think about how systems will fail before they do, and you build for stability and operational simplicity.
  • You are energized by the intersection of systems and the people who use them. You want researchers and engineers to have great tools, not just working ones.
  • You are a patient, generous mentor. You grow the people around you.
  • You are direct, give well-reasoned dissenting opinions when you have them, and do not let ideas roll by unchallenged when you see a better path.

The base salary for this role is anticipated to be between $150,000 and $300,000, which is based on information at the time of posting. This position may also be eligible for additional forms of compensation, such as a discretionary bonus, and benefits. Discretionary bonus can be a significant portion of total compensation. Actual compensation for successful candidates will be carefully determined based on a number of factors, including their unique skills, qualifications and relevant experience.
Benefits:
  • Benefits: For full-time employees, fully paid medical, dental, and vision for employees and dependents, competitive 401k plan, employer-paid life & disability insurance
  • Perks: Wellness programs, casual dress, snacks, lunch, game room, team and company events
  • Development: Open environment to maximize learning and knowledge sharing
  • Time: Generous PTO, paid holidays, competitive paid caregiver leaves

Aquatic Capital
This role represents a unique opportunity to join a quantitative investment manager in its early stage of growth. The firm's culture will be shaped by collaboration, meritocracy, ambition, and calm determination.
