ZenBusiness Inc. is hiring a Conversational AI & Prompt Engineer

ZenBusiness Inc. is looking for a Conversational AI & Prompt Engineer to craft the voice, reasoning, and effectiveness of our AI agent, Velo. Your mission is to ensure every interaction is clear, trustworthy, and results-driven by evolving prompts, dialogue flows, and decision logic through rapid experimentation.

What You'll Do

• Analyze conversation transcripts and user feedback to identify areas of confusion, failure, and prompt leakage.
• Work with the Customer Impact Team Product Lead to define and track conversational KPIs like resolution rate, containment rate, and user satisfaction.
• Optimize prompts and model selection for cost efficiency, response latency, and scalability in production.
• Collaborate with engineers to improve conversation-specific evaluation criteria, such as NLU accuracy and intent recognition.
• Design and maintain evaluation frameworks to measure prompt performance using golden datasets and automated scoring.
• Implement guardrails to reduce hallucinations, prevent prompt injection, and ensure compliant, safe responses.
• Collaborate on the design, mapping, and implementation of complex conversation flows, including error recovery and contextual handoffs.
• Own the continuous optimization of system prompts and instructions for LLMs like Gemini and OpenAI to ensure Velo's responses are accurate, tone-consistent, and on-brand.
• Design and optimize structured outputs, function calling, and tool-routing logic for accurate data capture and downstream system integrations.

What We're Looking For

• 5+ years of total professional experience.
• 2+ years in Conversational AI, Applied LLM Engineering, Prompt Engineering, or NLP systems in production environments.
• Deep experience designing and optimizing prompts for GPT, Gemini, or similar models, including structured outputs and function calling.
• Practical experience designing and tuning RAG pipelines (chunking, embeddings, retrieval evaluation).
• Experience building evaluation datasets and running prompt experiments, including A/B testing and automated scoring.
• Proficiency in Python or TypeScript.
• Experience integrating LLM APIs in production systems.
• Ability to analyze conversational performance using data and logs to drive measurable improvements.
• Strong systems thinking, empathy for users, and ability to translate business logic into scalable AI behavior.

Nice to Have

• Experience with agentic systems, similar to Decagon, Agentforce, or Fin.

Technical Stack

• Languages: Python, TypeScript
• Models & APIs: GPT, Gemini, LLM APIs
• Systems: RAG Pipelines

Team & Environment

You will report to the Senior Director of Growth & AI.

Benefits & Compensation

• Medical, vision, dental, disability, and life insurance.
• Parental and military leave.
• Employee assistance program.
• 401k + match.
