We’re looking for a hands-on Principal Engineer (AI Systems) who loves to build, not just design.
You’ll spend your time writing code, experimenting with LLMs, and turning ideas into production-grade Generative AI systems. You’ll work directly on Retrieval-Augmented Generation (RAG), LLMOps, and multi-agent orchestration frameworks, solving real technical problems every day.
This is a purely technical IC role, not a managerial one. You’ll lead by example, mentor through code reviews, and own end-to-end technical delivery.

Key Responsibilities

  • Design and code RAG systems with embeddings, hybrid search, and evaluation pipelines.
  • Develop hands-on multi-agent orchestration frameworks (LangGraph, AutoGen, CrewAI, or custom).
  • Implement and maintain LLMOps pipelines for prompt versioning, cost tracking, and evaluation.
  • Integrate AI workflows with backend services and data layers for real-world scalability.
  • Experiment with LLMs for retrieval, summarization, and personalization use cases.
  • Contribute directly to code, architecture reviews, and performance improvements.
Collaborate with data and platform engineers to deploy and optimize GenAI solutions.

Skills, Knowledge and Expertise

Must-Have Skills

  • 5+ years of backend or ML engineering experience, with strong Python coding skills.
  • Proven experience shipping RAG systems (vector DBs, embeddings, chunking).
  • Familiarity with orchestration frameworks (LangGraph, LangChain, AutoGen, or similar).
  • Understanding of LLM behavior, evaluation, and fine-tuning workflows.
  • Experience with APIs, microservices, and cloud-native development (AWS preferred).

Nice-to-Have

  • Experience with unstructured data (PDFs, tables, images).
  • Familiarity with distributed systems concepts (async, message queues, caching).
  • Experience with LLM evaluation or reinforcement learning from feedback (RLAIF).
  • Understanding of data versioning or retrieval metrics.

Soft Skills

  • Builder mindset — thrives on writing, debugging, and improving production code.
  • Collaborative, humble, and open to feedback.
  • Strong communicator who explains design decisions clearly.
Influences through contribution, not hierarchy.
