Job Description

Job Description**

  • 10+ years of experience building large-scale distributed systems + strong experience with LLM systems, agentic workflows or advanced ML infrastructure
  • Proven ownership of complex, cross-cutting agentic systems spanning multiple teams or products.
  • Strong engineering fundamentals across backend systems, APIs, data pipelines, and cloud infrastructure.
  • Deep experience across the agentic AI stack, including planning, tool use, memory, and evaluation.
  • Fluency with AI-assisted and agentic development workflows.
  • Comfort operating in ambiguous problem spaces and translating them into shipped, reliable autonomous systems.
  • Ability to influence technical direction and align teams without formal authority.
  • Experience in workflow engines, async processing, queues, and streaming systems.
  • Languages: Python, Go, TypeScript
  • APIs and services: REST, gRPC
  • Cloud and infrastructure: AWS and/or GCP, Kubernetes
  • Distributed systems: event-driven architectures, including Kafka
  • Orchestration Frameworks: LangGraph, LangChain, AirFlow, etc
  • Integration of commercial and open-source LLMs into agentic workflows
  • Agent and orchestration frameworks such as LangChain, LlamaIndex, Semantic Kernel, or CrewAI, with strong judgment about when to use frameworks versus building lighter-weight primitives
  • Model-level work using PyTorch and the Hugging Face ecosystem (embeddings, fine-tuning, inference tooling), with some exposure to TensorFlow
  • Strong schema, validation, and state management practices using tools such as Pydantic (Python) and Zod (TypeScript)
  • Drive technical direction for agentic AI initiatives, influencing architecture patterns, autonomy boundaries, and system design.
  • Design, build, and operate production-grade agentic AI systems used across multiple products.
  • Own and evolve shared agentic AI capabilities, including:
  • Agent frameworks and orchestration layers
  • Planning, tool use, and memory strategies
  • Retrieval and grounding (RAG) pipelines
  • LLM infrastructure, inference, and model gateways
  • Evaluation, observability, and safety tooling for autonomous systems
  • Lead technical design reviews and help teams navigate tradeoffs involving autonomy, safety, reliability, scalability, and cost.
  • Partner across teams to deliver complex, cross-cutting agentic AI initiatives from concept to pro duction.
  • Evaluate emerging models, techniques, and agentic patterns and translate them into practical, enterprise-ready improvements.
  • Mentor senior engineers and raise the technical bar for agentic AI development through example and influence.
