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
