About the role

We are hiring a Chief Agentic Systems Architect

WHAT YOU’LL DO

AGENT‑OPERABLE SYSTEM ARCHITECTURE

  • Decompose legacy monoliths into agent‑readable, modular systems with strict boundaries and single responsibility
  • Lead incremental modernization using the Strangler Pattern, wrapping legacy logic in modern, contract‑driven interfaces
  • Enforce SOLID principles, Dependency Injection, and Hexagonal Architecture to ensure deterministic AI execution and low regression risk

AGENTIC FRAMEWORK & MCP LEADERSHIP

  • Architect and maintain the agent context layer: standardized Skills, Rules, and Commands for AI‑driven engineering workflows
  • Build and operate Model Context Protocol (MCP) servers exposing legacy APIs, services, and databases as typed, secure, AI‑consumable tools
  • Own contract‑first API design as the primary interface between human intent and autonomous agent execution

ENGINEERING GOVERNANCE & AI QUALITY CONTROL

  • Act as architectural gatekeeper for AI‑generated pull requests, ensuring scalability, security, and long‑term maintainability
  • Mandate test‑driven development (TDD) and characterization testing to preserve legacy behavior during refactoring
  • Monitor and optimize agentic reasoning loops to balance cost, speed, and architectural integrity

WHAT WE’RE LOOKING FOR

  • 15+ years in software architecture, platform engineering, or technical leadership
  • Proven experience modernizing large, undocumented legacy systems
  • Deep hands‑on expertise with TypeScript, .NET, and Node.js
  • Strong background in API design, distributed systems, and modular architectures
  • Practical experience with agentic development, MCP, LLM tooling, or AI‑assisted engineering
