Job description

  • Define and drive the technical vision and architecture for AI systems within Realm-X
  • Design and build deep, context-aware agents leveraging domain ontologies and structured business primitives
  • Lead the development of agentic workflows that combine reasoning, planning, and execution
  • Architect systems for real-time, multi-modal AI agents across communication channels
  • Build and evolve platform capabilities to enable broad internal adoption
  • Translate ambiguous, high-impact problems into scalable, production-ready AI systems
  • Establish best practices for LLM evaluation, observability, safety, and iteration loops
  • Collaborate cross-functionally with product, design, and engineering leaders to shape strategy and execution
  • Mentor engineers and raise the technical bar across the organization
  • Identify and introduce emerging AI technologies and paradigms that create leverage for the business

Requirements

  • Think in terms of systems and platforms, not just features
  • Track record of building and deploying ML/AI systems in production at scale
  • Comfortable operating in high ambiguity and defining direction where none exists
  • Ability to lead through influence, aligning multiple teams around a technical vision
  • Balance long-term architecture with pragmatic delivery
  • Motivated by high-impact problems that shape products and business outcomes

Technical Experience

  • Master's or Ph.D. in Computer Science, Machine Learning, or a related technical field (required)
  • Extensive experience developing and deploying machine learning systems in production environments
  • Strong software engineering expertise with languages such as Python, Go, Ruby, or JavaScript
  • Deep understanding of distributed systems, APIs, and cloud infrastructure (AWS or similar)
  • Experience leading large, cross-functional technical initiatives
  • Ability to design systems that integrate structured data, models, and Real Time decisioning

Nice to Have

  • Experience with LLMs, AI agents, and tool-using systems (eg, LangChain, LangGraph, OpenAI APIs)
  • Familiarity with agentic architectures, planning/execution loops, and orchestration frameworks
  • Experience building domain-specific ontologies, knowledge graphs, or semantic layers
  • Background in workflow orchestration systems (eg, Temporal)
  • Experience building platforms that enable other engineering teams
  • Exposure to multi-modal AI systems (voice, chat, email, etc.)
