About Brainwave Science 

Brainwave Science is a deep-tech company building next-generation cognitive AI systems at the intersection of artificial intelligence, neuroscience, biosignals, mathematics, and human cognition. 

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.
