Job description

At BairesDev®, we've been leading the way in technology projects for over 15 years. We deliver cutting-edge solutions to giants like Google and the most innovative startups in Silicon Valley.

Our diverse 4,000+ team, composed of the world\'s Top 1% of tech talent, works remotely on roles that drive significant impact worldwide.

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.

Python AI Engineer at BairesDev

In this role, you\'ll build the agent and retrieval layer of an enterprise AI assistant serving thousands of employees, where an orchestrator invokes skills and routes to specialized agents exposed as internal services. This is a production system that already exists and keeps evolving, not a greenfield prototype. You\'ll own evaluation coverage for the behavior you ship, working primarily in Python, with some frontend work as your features require it.

What You\'ll Do:

• Build agent and retrieval capabilities for a production AI assistant.
• Build LangGraph flows and RAG pipelines over structured and unstructured sources.
• Hold evaluation coverage on the AI behavior you ship.
• Extend the existing Next.js front end where your features require it.

What we are looking for:

• 5+ years of experience with Python, 8+ years for lead-level scope.
• Proven experience with LLM systems running in production, built, maintained, and evolved, not just taken from zero to one.
• Hands-on experience with LangChain or LangGraph.
• Experience with RAG over structured and unstructured sources.
• Experience with AWS.
• Availability to work PST hours.
• Advanced proficiency in English.

Nice to have:

• Experience with LLM evaluation and tracing, including LangSmith, LLM-as-judge, or golden datasets.
• Some experience with React or TypeScript.
• Experience with multi-agent orchestration.
• Familiarity with vector databases, MCP servers, or streaming agent interactions.

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

• 100% remote, work from anywhere.
• Excellent compensation in USD or your local currency if preferred.
• Hardware setup for you to work from home.
• Paid parental leave, vacation, and national holidays.
• Innovative and multicultural work environment.
• Collaborate and learn from the global Top 1% of talent in each area.
• Supportive environment with mentorship, promotions, skill development, and diverse growth opportunities.

Join a global team where your unique talents can truly thrive and make a significant impact!
