AI Principal Engineer (Agentic AI / Marketplace Platforms)
Location: US / Remote
Role Type: Full-Time | Leadership + Hands-on Builder
The Opportunity
We are building a next-generation AI-native marketplace platform where intelligence is not a feature, but the foundation.
We re looking for an AI Principal Engineer who can architect and build the AI core from zero to scale owning everything from LLM orchestration to control planes and agent ecosystems.
This is a rare builder role: you won t be integrating AI you ll be defining how AI systems operate at scale in a real-world marketplace.
What You ll Own
Architect and deliver a full-stack AI platform powering marketplace intelligence
Build agentic AI systems using leading models from OpenAI and Anthropic (Claude)
Design and implement Model Context Protocol (MCP) servers for tool + model interaction
Create a centralized AI Control Plane:
Model routing & multi-LLM orchestration
Prompt lifecycle management
Guardrails, governance, and observability
Develop real-time decision engines for matching, pricing, and recommendations
Build scalable AI infrastructure (RAG, vector memory, knowledge systems, ingestion pipelines)
What We re Looking For
Builder DNA
You ve built 0 1 systems not just optimized existing ones
You are deeply hands-on and still love coding complex systems
AI Depth
Strong experience with LLM ecosystems like OpenAI, Anthropic
Expertise in:
Agentic workflows & multi-agent systems
RAG and memory architectures
Prompt engineering and evaluation
Tool orchestration and function calling
Systems & Architecture
Experience designing:
AI Control Planes
MCP servers or equivalent frameworks
Distributed, event-driven architectures
Strong cloud-native engineering (AWS/Google Cloud Platform/Azure)
Data & Intelligence Systems
Experience with:
Vector databases & knowledge graphs
Crawl-based or large-scale ingestion systems
Real-time AI inference pipelines
What Sets You Apart
You think in systems, not features
You can translate ambiguity into working AI architectures
You ve built or contributed to marketplace or platform ecosystems
You understand the trade-offs of real-world AI systems (latency, cost, accuracy, safety)
Impact
Define the AI backbone of a marketplace platform
Build systems that directly drive revenue, automation, and decisioning
Shape how agentic AI platforms are designed and scaled
Tech Landscape
LLMs: OpenAI, Anthropic
Backend: Python / Node.js / Java
Data: Vector DBs, Graph DBs
Cloud: AWS + Kubernetes
Streaming: Kafka / Event-driven systems
Why This Role
True greenfield AI platform build
High ownership, high visibility
Work at the edge of agentic AI + marketplace systems
