At Amazon's Fin Tech organization, we are building AI systems that process hundreds of millions of financial transactions, turn complex documents into actionable intelligence, and power autonomous agents that learn from every customer interaction. We are looking for a Senior Applied Scientist to lead the development of generative AI applications that change how finance teams work, tackling problems at the intersection of large language models, multi-agent systems, and real-world financial operations.

Key job responsibilities

What You'll Work On:

• Building AI systems that finance teams trust enough to rely on without manual review, where precision isn't a nice-to-have, it's a compliance requirement
• Designing agents that learn from user corrections and get measurably better with every interaction, not just at the next model release
• Solving inference at massive scale using tiered model architectures, intelligent routing, and small language models that deliver production-grade accuracy at a fraction of frontier model cost
• Developing evaluation frameworks that catch quality regressions before customers do and gate every model change before it ships

Who Thrives Here:

• You're someone who cares as much about shipping as about research.

• You've built models that run in production, not just in notebooks.

• You're comfortable working across the full stack, from model architecture to deployment to measuring whether the customer's workflow actually changed.

• You operate well in cross-functional settings where science, engineering, and business teams inform each other continuously.

• You'd rather solve a hard real-world problem than optimize a benchmark.

What Makes This Different:

Your work ships to production and directly changes how thousands of finance professionals operate daily
The problems are genuinely hard: financial data is messy, regulated, high-stakes, and operates at a scale where naive LLM approaches break down
You'll work across multiple domains — from contract intelligence to cash application to financial data investigation — not a single narrow use case

Work/Life Balance

We value work-life harmony. Achieving success at work should never come at the expense of sacrifices at home, which is why we strive for flexibility as part of our working culture. When we feel supported in the workplace and at home, there's nothing we can't achieve.

Basic Qualifications

• PhD, or Master's degree and 6+ years of applied research experience
• 3+ years of building machine learning models for business application experience
• Experience with neural deep learning methods and machine learning
• Experience programming in Java, C++, Python or related language

Preferred Qualifications

• Experience with modeling tools such as R, scikit-learn, Spark MLLib, Mx Net, Tensorflow, numpy, scipy etc.
• Experience with large scale distributed systems such as Hadoop, Spark etc.
• Have publications at top-tier peer-reviewed conferences or journals
