The Vision
We do not believe in the "one size fits all" AI. We are building a Composable AI Microservice Architecture composed of hundreds of hyper-specialized services. Each service is a "Generic Function" (an LLM) that has been expertly programmed through data, context, and tool-integration to dominate a specific, high-leverage task.
As a Senior Software Engineer, Core AI, you are the primary builder of these intelligent services. You aren't just calling APIs; you are designing the logic, memory structures, and retrieval systems that turn a raw model into a production-grade agent. You will be at the forefront of moving our company from static specifications to a dynamic, agentic reality.
The Mission: Specialized Intelligence
Our philosophy is simple: LLMs are generic until they are grounded. You will drive excellence by treating LLM application development as an optimization and experimentation problem. Your goal is to move beyond "generic chat" to build services that exhibit high agency while maintaining deterministic precision.
What You’ll Do:
What We’re Looking For:
The Reality of the Work
This is a high-velocity building role. You won't be writing research papers; you will be shipping production code. One week you might be building a specialized agent for Global Support, and the next you'll be optimizing a design-to-code microservice. Your success is measured by the number of high-leverage human workflows you successfully augment.
We are creating the company’s AI operating layer, built from focused, composable services. If you want to shape how those services fit together, let’s talk.
