You will play a key role in productionizing ML models, optimizing pipelines, and ensuring seamless deployment of high-performing recommendations and search systems.

• Partner with Data Scientists, Engineers, and Product Managers to turn ideas into production-grade solutions with measurable business impact.

• Mentor and guide engineers, review designs, and set technical direction.

• Evaluate and implement new technologies to expand our capabilities.

• Champion reusability and scalability, enabling faster iteration cycles and reducing tech debt across recommendation/search pipelines.

WE’D LOVE TO MEET YOU IF

• 8+ years of experience in ML Engineering, including deep expertise in building production-grade ML systems at scale.

• Proven track record of shipping ML models to production, including complex pipelines with real-time serving and batch processing.

• Expertise in cloud infrastructure (AWS), orchestration tools (Airflow), and feature stores.

• Hands-on experience with Databricks, Spark, and distributed training and inference.

• Strong knowledge of retrieval/ranking/recommendation systems.

• Ability to lead through influence, drive alignment on architecture, and set engineering standards across multiple teams.
