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 As part of Tower Research's Core Engineering team, you will develop a multi-tenant research compute platform capable of dynamically orchestrating large scale ML workloads across a hybrid compute infrastructure of GPUs and CPUs. Your primary mission is to work closely with Quant Researchers, Portfolio Managers, and Infrastructure teams, to build a unified, elastic, and multi-tenant research substrate. Key Responsibilities • Elevating Researcher Experience: Design intuitive platform abstractions, APIs, scheduler wrappers, and a durable job control plane so researchers can seamlessly launch simulations, distributed training runs, and complex research pipelines without incurring infrastructure overhead • Architecting Multi-Tenant Scheduling & Isolation: Build a multi-tenant compute substrate combining HPC-grade batch scheduling (gang scheduling, topology awareness, fair share) with cloud-native flexibility, enforcing strict tenant isolation across trading desks • Enabling Multi-Datacenter & Multi-Cloud Compute Portability: Establish infrastructure agnostic execution abstractions that enable compute workloads to run transparently across multiple on-premise datacenters or burst into external cloud providers • Standardizing Workflow Orchestration: Evaluate, select, and integrate production-grade job graph orchestration engines to automate multi-stage feature, training, and backtesting pipelines • Building Fault-Tolerant Research Pipelines: Implement automated failure detection, retry-on-fault mechanisms, and high-performance checkpointing to ensure long-running distributed jobs survive hardware degradation and faults without manual intervention • Optimizing Data-Paths: Profile and eliminate I/O bottlenecks, ensuring distributed ML workloads align with high-speed network fabrics and high-performance storage • Delivering Observability & Cost Transparency: Implement comprehensive telemetry to track compute utilization, queue pressure, and GPU/CPU cost attribution, giving Portfolio Managers and Senior Management clear visibility into resource consumption and ROI Technical Requirements • HPC Administration: Deep experience with HPC job schedulers (e.g., Slurm), including gang scheduling, fair-share priority trees, topology-aware node allocation, and containerized HPC execution • Kubernetes-native Engineering: Advanced understanding of Kubernetes architecture, CRDs, HPC focused operators, admission controllers and GPU-native schedulers • Distributed ML Computing Frameworks: Familiarity with distributed computing frameworks (e.g., Ray) and deep learning frameworks (e.g., PyTorch, JAX) with multi-node scaling primitives • Workflow Orchestration Expertise: Hands-on experience evaluating, architecting, and operating job graph orchestration frameworks • Multi-Platform Architecture: Experience designing vendor-agnostic infrastructure layers, cloud-bursting strategies, and compute execution spanning multiple on-premise datacenters and public cloud environments • Storage & Network Performance: Familiarity with high-performance storage solutions and high-speed network fabrics for large scale research workloads • Compute Observability: Proven track record building cluster-wide telemetry and cost-attribution platforms for multi-tenant environments • Architectural Leadership Mindset: A strong platform engineering mindset focused on reducing friction for researchers while maintaining rigorous operational efficiency, cost transparency, and system scalability Anticipated annual base salary range $200,000-$300,000, plus eligible for discretionary bonus Tower’s headquarters are in the historic Equitable Building, right in the heart of NYC’s Financial District and our impact is global, with over a dozen offices around the world.  At Tower, we believe work should be both challenging and enjoyable. That is why we foster a culture where smart, driven people thrive – without the egos. Our open concept workplace, casual dress code, and well-stocked kitchens reflect the value we place on a friendly, collaborative environment where everyone is respected, and great ideas win. Our benefits include: • Generous paid time off policies • Savings plans and other financial wellness tools available in each region • 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 At Tower, you’ll find a collaborative and welcoming culture, a diverse team and a workplace that values both performance and enjoyment. No unnecessary hierarchy. No ego. Just great people doing great work – together. Tower Research Capital is an equal opportunity employer.
