The Retail Business Services (RBS) Technology team's mission is to transform the Amazon's e-commerce business through technology, delivering order of magnitude higher speed, scale and impact. This Principal Engineer role leads a strong charter to accelerate business functions currently done manually, by envisioning and developing ML/GenAI-driven Agentic core platforms, thus enabling self-service building of agents to perform cognitive tasks autonomously.

Providing a delightful experience to Amazon's e-commerce customers and selling partners requires thousands of various types of tasks performed by business teams that operate at the interface of the company as well at the heart of it. These teams work with vendors to source products to increase selection and choice for the customers, audit the app/website experience to ensure trustworthy information is provided to customers to enable confident purchases, learn from customer feedback on product reviews and returns, and ensure the inventory is placed at the right location for fast delivery of orders, just to name a few activities. Manual activities reduces speed of operations, introduce undesirable variations and limit scale. Hence there is a need to automate these, while overcoming the challenges of 1) task-by-task automation being inefficient, 2) human cognitive work automation requires equivalent or better intelligent systems, 3) a vast variety of business use cases, and 4) ability to integrate with the existing ecosystem of 100s of tools.

The Principal Engineer sets the right quality bar for resilience, latency, maintainability, accuracy (precision/recall), usability, security/privacy and efficiency, for the team to adhere to. The ideal candidate is one who thrives on understanding the complexity of software systems, and brings a nuanced understanding of different aspects of automation technologies spanning machine learning and big data processing. Working with the rest of the team, peers and stakeholders, they will lead the technology decisions to empower thousands of task automation, from simple few steps, to complex ones involving several tool integrations and conditional steps. The enormous challenge requires creative thinking and passion to use technology to make customers' and internal teams' lives better.

The Principal Engineer in this role collaborates with the team to grow/mentor talent, review work constructively and create a supportive learning environment. They never lose sight of the customer needs, and tackle ambiguous technical and product challenges to continually find ways to serve them better. They build mechanisms to expand and maintain coverage of the platforms to multiple geographies in which Amazon operates, multi-lingual needs, multitude of product types, and hundreds of teams.
