Applied GenAI & LLM Data Scientist

GCS Recruitment Specialists; California (MO); On-site; USD 140,000 - 200,000; Full time

Job summary

Amazon Translation Services is seeking a Data Scientist to lead GenAI and LLM initiatives, building production-grade models for multilingual content translation and localization. You will fine-tune models, optimize OCR and image processing workflows, and deploy scalable ML systems with low latency.

The role demands 3+ years of ML model experience, deep LLM expertise beyond prompts, and strong Python skills.

Qualifications

• 3+ years building machine learning models for real business applications.
• Hands-on LLM experience that goes beyond prompt engineering: fine-tune models, adjusting weights and parameters, and working directly with model internals.
• A solid understanding of how foundation models work under the hood, and the judgment to pick the right model for the problem. Open source or closed models are both fine.
• Experience building and deploying production-grade models at scale.
• Strong programming in Python. Java or C++ backgrounds are also welcome.
• PhD, or Master's degree plus 4+ years of experience in Computer Science, Computer Engineering, Machine Learning or a related field.
• Comfort with ambiguity and autonomy on an early-stage team, where engineering judgment matters as much as model performance.

Responsibilities

• Evaluate and select models for incoming text, image and video content.
• Fine-tune models across the full image localization workflow: OCR extraction, grouping text within images, translation, and rendering translated text back onto the image. The work spans many languages and content types.
• Match model size to the problem. That means choosing the smallest model that does the job well rather than over- or under-engineering it.
• Find automation opportunities across the translation pipeline (training, sampling, inferencing) and work with the MLOps team to automate repeated manual work.
• Design and ship production-grade ML solutions that handle millions of pieces of content daily at low latency.
• Run data analysis to drive recommendations, and explain technical approaches clearly to both technical and non-technical stakeholders.
