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, enabling self-service building of agents to perform cognitive tasks autonomously. These teams work with vendors to source products to increase selection and choice for customers, audit the app/website experience to ensure trustworthy information for confident purchases, learn from customer feedback on product reviews and returns, and ensure inventory is placed at the right location for fast delivery. Manual activities reduce speed of operations, introduce undesirable variations and limit scale. 1) task-by-task automation being inefficient, 2) human cognitive work automation requiring equivalent or better intelligent systems, 3) a vast variety of business use cases, and 4) the ability to integrate with the existing ecosystem of hundreds of tools.
The Principal Engineer owns the charter of defining and building scalable platforms for automation, leveraging state-of-the-art technologies such as GenAI and Agentic infrastructure. It will define the core services and platforms that enable rapid automation through leverage of ML/GenAI. These platforms will enable self-service, low-code/no-code automation by deskilling automation development. 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 thrives on understanding the complexity of software systems and brings a nuanced understanding 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 automations, from simple steps to complex ones involving several tool integrations and conditional steps. The enormous challenge requires creative thinking and a passion to use technology to improve customers' and internal teams' lives.
