About the role

Senior AI Engineer at Zalos, building the AI agent architecture and production-grade LLM pipelines to enable cross-system enterprise automation across SAP, Salesforce, and ServiceNow with auditable actions.

Responsibilities

  • Design and own the core agent architecture: how we take a natural language intent, decompose it into steps, call the right APIs and UI agents, handle failures gracefully, and close the loop with the user
  • Build reliable, production-grade LLM pipelines covering context management, tool use, structured outputs, and multi-step reasoning across systems with real enterprise data
  • Create evaluation frameworks that let us ship with confidence: evals, replay testing, regression detection, and output quality scoring against enterprise workflows
  • Build computer-use agents that can navigate legacy enterprise UIs including SAP GUI, ServiceNow, and thick clients, reliably enough to trust in production
  • Work directly with the founders and customers to understand where AI fails in real enterprise workflows and translate that into better systems
  • Set the technical standards for how we build AI at Zalos. You'll be defining the patterns the rest of the team builds on

Qualifications

  • You've shipped AI-powered features that real users depend on in production. You know what breaks and how to prevent it
  • Deep hands-on experience with LLM APIs, agentic patterns, and tool/function calling. Not just wrappers around OpenAI, but genuine systems-level thinking about how agents fail
  • You think about reliability, latency, and cost as first-class engineering concerns, not afterthoughts
  • You build evals before you ship, not after something breaks in front of a customer
  • Strong Python; comfortable owning the full loop from prompt design to deployed API
  • High ownership: you take something from an ambiguous problem statement to a clean, working solution with minimal hand-holding
  • You're pragmatic. Startups are always on fire somewhere. You know when to let something burn and when to drop everything
