LLM & AI/ML Pipelines: Collaborate with data science teams to build, fine-tune, deploy, and scale Large Language Models (LLMs) and Generative AI applications within production AWS environments (utilizing services like Amazon SageMaker, Bedrock, or integrated partner platforms).
Industry Domain Application: Apply custom cloud solutions tailored specifically to retail and e-commerce challenges, including inventory optimization, personalization engines, and transactional data streams.
Collaboration & Integration: Work closely with cross-functional technical teams, aligning cloud engineering workflows with Sesheng LLC’s broader partner ecosystem solutions.

Required Qualifications & Experience

Industry Experience (Mandatory): Proven track record of working within the Retail or E-commerce sector, displaying a strong understanding of high-volume digital commerce architectures and customer data patterns.
AWS Expertise: Minimum of 3–5 years of hands-on experience engineering and administering production AWS environments. Relevant AWS Certifications (AWS Solutions Architect, AWS DevOps Engineer, or AWS Data Engineer) are highly valued.
Advanced Data Engineering: Deep, demonstrable experience with data warehouse transformation, data modeling, lakehouse architectures, and big data technologies (e.g., Snowflake, Redshift, or Databricks).
AI/ML & LLMs (Mandatory): Practical experience building, deploying, or fine-tuning LLMs and integrating Generative AI components into broader application architectures.
Education: A Master’s degree in Computer Science, Computer Engineering, or a highly related technical discipline is strongly desired.
