Role summary

Tower Research Capital, a quantitative trading firm, seeks a GPU Systems Engineer to design, deploy, and operate large-scale distributed GPU clusters. This role involves deep Linux system administration, performance tuning across compute, storage, and network, and building automation for provisioning and monitoring. The engineer will collaborate with researchers to optimize GPU workloads and work with vendors on hardware and software issues. Requires 5+ years of experience in large-scale Linux systems (HPC, AI, or distributed infrastructure) and hands-on experience with GPU workloads and Python for automation. Familiarity with configuration management tools and C/C++ or CUDA is also expected. The position offers a hybrid work model in NYC with a competitive salary and bonus.

Tower Research Capital is a leading quantitative trading firm founded in 1998. Tower has built its business on a high-performance platform and independent trading teams.

Our engineers solve challenging problems in the realms of low-latency programming, FPGA technology, hardware acceleration and machine learning. Our ongoing investment in top engineering talent and technology ensures our platform remains unmatched in terms of functionality, scalability and performance.

At Tower, every employee plays a role in our success. Our Business Support teams are essential to building and maintaining the platform that powers everything we do — combining market access, data, compute, and research infrastructure with risk management, compliance, and a full suite of business services. Our Business Support teams enable our trading and engineering teams to perform at their best.

At Tower, employees will find a stimulating, results-oriented environment where highly intelligent and motivated colleagues inspire each other to reach their greatest potential.

Summary:Trading and research at the firm run around the clock and across the globe, and they run on infrastructure this team designs, builds, and operates.

As part of R&D, you will join the engineers responsible for the compute, storage, operating systems, and automation behind that work at serious scale: hundreds of petabytes of storage and large CPU and GPU clusters spanning thousands of nodes.

The role is broad by design. One week you might be shaping the architecture of a new AI cluster, the next profiling a training job that will not scale, the next writing automation that keeps the whole fleet healthy with minimal human intervention.

Responsibilities:

  • Design, deploy, and scale distributed GPU clusters, from hardware selection and network topology through to production operation.
  • Track down performance bottlenecks across the full stack: compute, storage, network, and the seams between them.
  • Partner with researchers to profile and benchmark GPU workloads, then turn the findings into measurable speedups.
  • Build the automation that lets a small team operate thousands of nodes: provisioning, monitoring, diagnostics, and self-healing.
  • Own infrastructure projects end to end, from scope and design through implementation and long-term support.
  • Qualify new generations of hardware and software, and work directly with vendors to root-cause complex issues.

    • Qualifications:

  • 5+ years engineering large-scale Linux systems in HPC, AI, or distributed-infrastructure environments.
  • Deep Linux fundamentals: installation, performance tuning, and debugging, down to the kernel when the problem calls for it.
  • Hands-on troubleshooting of distributed GPU workloads, with a strong mental model of GPU performance.
  • Working experience with GPUDirect RDMA. You understand how data moves between GPUs and the network, and what to check when it does not.
  • Solid Python for automation and tooling, plus CUDA or C/C++ experience. You can read, profile, and debug GPU code, not just operate the clusters it runs on.
  • Familiarity with configuration management tools such as Salt, Ansible, Puppet, or Chef.
  • Comfort diagnosing problems that cross hardware, OS, and network boundaries rather than stopping at one layer.
  • Clear communication. You will work daily with researchers, engineers, and vendors.

    • Nice to Have:

  • Experience with the rest of the NVIDIA stack, such as NCCL and NVLink.

    • Anticipated annual base salary range $200,000-$300,000, plus eligible for discretionary bonus.

  • Hybrid working opportunities
  • Free breakfast, lunch, and snacks daily
  • In-office wellness experiences and reimbursement for select wellness expenses (e.g., gym, personal training and more)
  • Company-sponsored sports teams and fitness events (JPM Corporate Challenge, Cycle for Survival, Wall Street Rides FAR and more)
  • Volunteer opportunities and charitable giving
  • Social events, happy hours, treats, and celebrations throughout the year
  • Workshops and continuous learning opportunities
