Systems Engineer

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.
