When you apply for this position, you're taking the first step in a process that goes beyond the ordinary. We aim to align your passions and skills with our vacancies, setting you on a path to exceptional career development and success.
Staff AI Engineer at BairesDev
In this role, you'll lead backend AI features end to end, owning a component of a larger body of work alongside a Principal Engineer and a tech lead. Staying hands‑on throughout, you'll build LangGraph flows and RAG pipelines while holding evaluation coverage on everything you ship. This is your opportunity to lead technically while remaining deeply hands‑on, unblocking engineers in your pod and shaping how production LLM systems are built, maintained, and evolved over time.

What You'll Do

• Lead and own backend AI features end to end, breaking down and delivering complex work.
• Build and maintain LangGraph agent flows and RAG pipelines over structured and unstructured data.
• Hold evaluation and tracing coverage on shipped AI behavior.
• Stay hands‑on across development phases, building alongside Principal and Senior engineers.
• Unblock Senior engineers in the pod and surface blockers early.

What We Are Looking For

• 8+ years of experience in Python.
• Proven experience building, maintaining, and evolving production LLM systems, not just zero-to-one projects.
• Hands‑on experience with LangChain and LangGraph, including agent flows, tool and skill invocation, and state management.
• Experience building RAG pipelines over structured and unstructured data.
• Experience with LLM evaluation and tracing, including LangSmith, LLM-as-judge, and golden datasets.
• 4+ years of experience with React/Next.js and TypeScript.
• Experience with MCP server development against structured databases and data lakes.
• Experience with streaming agent interactions, including LangGraph API and WebSockets.
• Background with CI/CD pipelines and service observability, including logging, tracing, and SLOs.
• Experience with distributed systems, microservices, and REST/GraphQL on AWS.
• Strong prompt engineering skills, iterating against measured output.
• Advanced proficiency in English.

Nice To Have

• Experience with model gateway and routing such as Bedrock or LiteLLM.
• Familiarity with agent-to-agent communication patterns (A2A).
• Experience with vector databases such as Pinecone, FAISS, Qdrant, or pgvector.
• Security mindset, including secure coding and AuthN/AuthZ practices.
• Analytics and data visualization experience.
• Experience with ServiceNow or enterprise workflow integration.

How we do make your work (and your life) easier:

• 100% remote work (from anywhere).
• Excellent compensation in USD or your local currency if preferred
• Hardware and software setup for you to work from home.
• Flexible hours: create your own schedule.
• Paid parental leaves, vacations, and national holidays.
• Innovative and multicultural work environment: collaborate and learn from the global Top 1% of talent.
• Supportive environment with mentorship, promotions, skill development, and diverse growth opportunities.
