• Drive the technical roadmap for core ML infrastructure, influencing platform choices and building cloud-native systems primarily on GCP.


• Operate with high autonomy, owning outcomes end-to-end, proactively identifying gaps, and raising the technical bar for the team.


• Set a high standard for code quality and system design, producing clear, principled, and extensible solutions that scale with the firm.


• Bring positive energy in every interaction with the team and foster inclusive collaboration

• Proven experience deploying and managing ML models in a production environment using tools like Kubeflow, MLflow, Airflow, or TFX


• Strong understanding of containerization technologies (e.g., Docker, Kubernetes/GKE) as applied to ML serving


• Familiarity with cloud computing environments (preferably GCP), including data storage and compute services


• Low ego, high empathy, and the capacity to collaborate effectively with diverse teams
