THE OPPORTUNITY
We are seeking an AI Interaction Engineer to design, implement, and optimize the way AI agents understand, respond, and act within enterprise workflows.
This role sits at the intersection of linguistics, context engineering, and enterprise AI systems. You will blend prompt engineering, context orchestration, and memory architecture to ensure large language models (LLMs) and multi-agent systems are accurate, reliable, and compliant in production.
If you are passionate about making AI smarter, context-aware, and enterprise-ready, this role is for you.
Key Responsibilities

• Prompt Engineering – Design, test, and refine prompt strategies to drive optimal agent behavior across diverse use cases.
• Context Orchestration – Build pipelines integrating RAG, knowledge graphs, APIs, and layered memory (short-term, long-term, episodic).
• Optimization – Optimize token usage and context allocation for long-running, multi-turn, and multi-agent workflows.
• Reusable Blueprints – Develop reusable interaction templates and context blueprints for engineering and product teams.
• Compliance & Guardrails – Implement safety, compliance, tone, and brand guardrails in agent workflows.
• Continuous Improvement – Use execution traces, feedback, and automated evaluation to improve agent responses.
• Experimentation – Conduct A/B testing on prompt and context variations to measure accuracy, latency, and cost trade-offs.
• Knowledge Management – Maintain a central library of tested interaction patterns and context management strategies.
• Research Tracking – Stay updated on multi-agent orchestration frameworks and the state of AI interaction design.
  

Skills & Qualifications
Must-Have

• 2–4 years in AI/ML engineering, NLP, or enterprise software development.
• Strong understanding of LLM architectures, prompt engineering, and context window limits.
• Hands-on with RAG pipelines, vector databases, and knowledge graph integration.
• Proficiency in Python and frameworks like LangChain, LangGraph, LlamaIndex.
• Familiarity with enterprise AI governance, privacy, and compliance standards.
• Proven ability to translate business objectives into structured AI interactions.
  

Good-to-Have

• Experience with multi-agent orchestration (MCP, A2A messaging, AgentBridge).
• Knowledge of reinforcement learning (RLHF, RLAIF, reward modeling).
• Exposure to edge AI deployment and quantized inference.
• Domain knowledge in BFSI, GRC, SOC, or FinOps.
