Chief Architect

Responsibilities

• Hands-On Architecture and Technical Decision-Making
• Serve as Legion’s senior-most hands-on technical authority for complex architecture, system design, and platform evolution.
• Personally dive into code, design documents, production incidents, performance bottlenecks, and implementation tradeoffs to diagnose root causes and guide technical direction.
• Lead the hardest technical decisions across AI systems, optimization engines, distributed systems, data architecture, reliability, scalability, security, and platform modernization.
• Write prototypes, reference implementations, architecture decision records, technical specifications, and design patterns where needed to unblock teams and establish clear direction.
• Make high-consequence technical decisions with incomplete information, balancing correctness, simplicity, speed, scalability, reliability, cost, and long-term maintainability.
• Challenge architectural drift, unnecessary complexity, weak abstractions, and short-term decisions that create long-term platform risk.
• Partner directly with Staff, Principal, and senior engineering leaders in design reviews, code-level discussions, and implementation planning.
• Platform Architecture and Technical Vision
• Define and own the long-term architecture for Legion’s AI-driven Workforce Management platform across application services, data infrastructure, ML systems, optimization engines, APIs, integration architecture, developer platforms, and enterprise-scale operations.
