Job summary

EVA is seeking a Chief Agentic Systems Architect to transform a 10+ year legacy codebase into a high‑velocity, agent‑operable architecture. This role sits at the intersection of software architecture, AI‑agent orchestration, and engineering governance.

You will design system patterns, MCP interfaces, and cognitive context layers that allow LLMs and autonomous agents to safely refactor, test, and ship production code with minimal human intervention.

Qualifications

• 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.

Responsibilities

• Decompose legacy monoliths into agent-readable, modular systems with strict boundaries.
• Lead incremental modernization using the Strangler Pattern and contract-driven interfaces.
• Enforce SOLID, Dependency Injection, and Hexagonal Architecture for deterministic AI execution.
• Architect and maintain the agent context layer with standardized Skills, Rules, and Commands.
• Build and operate MCP servers exposing legacy APIs as typed, secure AI tools.
• Own contract-first API design as the interface between human intent and autonomous execution.
• Gatekeep AI-generated PRs for scalability, security, and maintainability.
• Mandate TDD and characterization testing to preserve legacy behavior.
• Monitor and optimize agentic reasoning loops balancing cost and integrity.
