About the role

Foundational AI Engineer role at Numeral focused on building end-to-end LLM-powered automation systems, model orchestration, tool calling, and scalable backend services in a hybrid NYC environment.

Responsibilities

  • Design, build, and operate production AI systems, including tool-calling agents, model orchestration layers, and RAG.
  • Implement and maintain AI integrations using modern frameworks, MCP servers, and external model providers.
  • Build and evolve scalable backend services and APIs that power automated workflows and customer-facing features.
  • Think in automation and workflows: design systems using tools like n8n, Claude Code-style agents, or similar orchestration approaches.
  • Make architectural decisions that balance latency, cost, reliability, and iteration speed.
  • Own infrastructure, observability, and performance for both AI and non-AI services.
  • Collaborate closely with product, design, and data teams to ship features that solve real customer problems.
  • Help define engineering best practices, AI safety/reliability norms, and our overall technical culture.

Qualifications

  • 7+ years of experience building products in high-growth environments.
  • 2+ years of experience building with LLMs.
  • Avid use of state-of-the-art AI development tools such as Cursor and Claude Code.
  • Fluency with backend technologies like PostgreSQL, Redis, and cloud services (AWS preferred).
  • Experience with frontend development, especially TypeScript and its ecosystem.
  • Strong product sense, balancing performance, flexibility, and speed.
  • Comfortable working in dynamic startup environments with evolving needs.
  • Excellent communication and collaboration skills.
  • Startup mindset: Not scared of ambiguity and hungry for rapid growth
  • Intensity & Ownership: This is not a 9-5 — we’re scaling rapidly and have a massive opportunity ahead of us.
  • Customer Obsession: You deeply care about the user experience and solving their problems
