What You’ll Do:

The Monolith Data Science team is building a layered reliability platform that shifts CoreWeave from reactive troubleshooting to proactive reliability engineering. The platform spans telemetry ingestion, feature engineering, anomaly detection, failure prediction, distributed straggler detection, and agentic root cause analysis. We partner closely with Fleet, Infrastructure, and AI Platform teams to improve cluster reliability, increase effective utilization (MFU), reduce MTTR, and protect uptime and revenue.

About the role:

As a Data Science Researcher, you will develop advanced statistical models and machine learning methodologies to optimize GPU utilization, workload scheduling, and infrastructure efficiency. You will design experiments, analyze large-scale system telemetry data, and prototype predictive and optimization algorithms that directly inform production systems. This role blends research rigor with real-world impact, turning complex infrastructure data into measurable improvements in performance and cost. You will collaborate cross-functionally to translate research insights into deployable solutions.

Who You Are:

  • MS or PhD in Computer Science, Statistics, Applied Mathematics, Machine Learning, or related quantitative field
  • 8+ years (or equivalent research experience) applying statistical modeling or machine learning to large-scale datasets
  • Strong proficiency in Python and scientific computing libraries (NumPy, pandas, SciPy, scikit-learn, PyTorch or TensorFlow)
  • Demonstrated experience designing and analyzing controlled experiments (A/B testing, causal inference, hypothesis testing)
  • Experience working with distributed data systems (Spark, Ray, Dask, or similar)
  • Proficiency in SQL and working with large-scale structured datasets
  • Experience building and validating predictive models in production or research environments
  • Strong understanding of optimization techniques (linear programming, convex optimization, stochastic optimization, or reinforcement learning)
  • Experience working with time-series data and performance telemetry
  • Ability to translate research findings into production-ready prototypes

Preferred: 

  • PhD with published research in systems optimization, distributed computing, ML systems, or performance modeling
  • Experience with GPU workloads, distributed training, or AI infrastructure
  • Familiarity with Kubernetes, containerized workloads, or cloud-native systems
  • Experience developing reinforcement learning or adaptive scheduling systems
  • Background in capacity planning, forecasting, or resource allocation modeling
  • Contributions to open-source ML or systems projects

Wondering if you’re a good fit? We believe in investing in our people, and value candidates who can bring their own diversified experiences to our teams – even if you aren't a 100% skill or experience match. Here are a few qualities we’ve found compatible with our team. If some of this describes you, we’d love to talk. 

  • You love uncovering hidden failure patterns in massive, noisy infrastructure datasets
  • You’re curious about building autonomous, agentic systems that investigate and explain system behavior
  • You’re an expert in reinforcement learning, predictive modeling, or large-scale data analysis
