Our work focuses on developing intelligent systems for

• Cognitive and behavioral analysis
• Stress and emotional state assessment
• Adaptive AI systems
• Biosignal intelligence
• Applied healthcare and security technologies

We operate in a fast-moving research and product environment where experimentation, originality, and rapid problem-solving are highly valued.

About the Role

We are looking for an experienced Conversational AI Engineer to build reliable, intelligent, and scalable conversational AI systems powering our cognitive AI platform.

• *This role is intended for engineers who have personally designed, deployed, and maintained production conversational AI or LLM systems. Candidates whose experience is limited to prototypes, hackathons, or proof-of-concept projects are unlikely to be a good fit.**

You will architect modern LLM solutions, improve chatbot reliability, and deliver production-grade conversational experiences for real users.

Key Responsibilities

• Design and improve production-grade conversational AI systems.
• Architect RAG, fine-tuning, or hybrid LLM solutions based on product requirements.
• Build reliable multi-intent chatbot workflows for text and voice.
• Improve response quality, retrieval accuracy, latency, and reliability.
• Optimize prompts, orchestration, and evaluation pipelines.
• Develop automated testing and evaluation frameworks.
• Diagnose and resolve production issues systematically.
• Collaborate with AI, research, and product teams.
• Document architecture, engineering decisions, and best practices.

Required Qualifications

• 4+ years of hands-on experience building and deploying production conversational AI systems.
• Demonstrated ownership of at least one production LLM application from design through deployment, monitoring, and continuous improvement.
• Prototype-only experience is not sufficient.
• Practical experience with RAG, fine-tuning, prompt engineering, and LLM evaluation.
• Experience designing production multi-intent conversational systems.
• Strong Python programming skills.

Preferred Qualifications

• LangChain, LangGraph, or LlamaIndex.
• Vector databases.
• Healthcare, wellness, or other regulated domains.
• Experience deploying scalable LLM applications.
• Experience implementing structured AI evaluation and testing practices.

Technologies You'll Work With

• Python
• OpenAI APIs
• LangChain
• LangGraph
• LlamaIndex
• Vector Databases
• FastAPI
• Docker
• Git

Why Join Brainwave Science?

• Build next-generation AI assistants using modern LLM technologies.
• Work on production AI systems with real-world impact.
• Influence the architecture of a growing AI platform.
• Collaborate with experienced AI engineers and researchers.
• Be part of a team that values technical excellence, ownership, and continuous learning.
