Job description

This is not a pure ML modeling role. The ideal candidate is excited about building reliable infrastructure, data pipelines, and developer-facing tools that make ML engineers more productive.

What You’ll Do

  • Design and build data infrastructure that supports large-scale feature and training set computation, transformation, and storage.
  • Develop frameworks for batch and real-time features with a focus on reliability, scalability, and ease of use.
  • Build platform capabilities for feature governance, including lineage tracking, validation, drift detection, anomaly monitoring, reproducibility, and versioning
  • Partner with ML engineers to ensure smooth integration of feature engineering workflows into ML production systems.
  • Build systems that support agentic ML workflows, including automated feature discovery, feature quality evaluation and feature lifecycle management
  • Contribute to operational excellence through observability, performance tuning, reliability engineering, and cost optimization initiatives.

Requirements

Do you have experience in Spark?, We are looking for an engineer with experience in building high-scale data infrastructure and exposure to ML platforms to help evolve and scale our feature management systems., * 3+ years in data infrastructure/platform engineering or ML infrastructure platforms.
