• Research and prototype multi-agent frameworks (open-source and commercial)
• Experiment with cutting-edge conversational AI and real-time speech processing techniques
• Contribute to evolving the team's LLMOps best practices
• Continuously improve conversational quality, RAG pipelines, and reduce latency

Must have

• 2+ years hands-on experience with LLMs (OpenAI or similar, open-source models)
• Strong knowledge in prompt engineering and LLM optimization strategies
• Experience in evaluating LLMs, designing and running evaluation frameworks, creating test datasets, and defining success metrics
• Familiarity with automated testing pipelines, building CI/CD-integrated eval systems that run on every prompt change
• Experience in multi-agent architecture, from design to development of orchestration of complex LLM systems
• Good understanding of transformer architectures and proficiency in LLM frameworks such as LangChain, LlamaIndex, or similar frameworks
• Proficiency in Python
• Experience with RAG pipelines and vector databases
• Experience in cross-functional teams, ability to work in fast-moving environments where you own outcomes, not just tasks. You're comfortable with ambiguity and excited by the challenge of figuring things out.
