Set the standard for AI-native development across the org, coaching Staff and Senior engineers on integrating AI tooling into architecture, design, and delivery to drive measurable speed and quality gains.

Software Development & Technical Craft

Lead architectural design and technical direction for systems spanning multiple teams, ensuring they are extensible, scalable, and built to enterprise-grade standards.
Introduce architectural patterns that get adopted as organizational standards, not just single-project fixes.

Problem Solving & Technical Judgment

Tackle complex challenges involving data gravity, security, and system coupling across teams and organizational boundaries.
Exercise sound judgment selecting architectural approaches that hold up as usage and team size grow.

Code Quality & Mentorship

Define code review and quality standards adopted across the engineering organization.
Mentor senior and mid-level engineers through design reviews and architectural discussions, setting the technical bar for the team.

Scope & Operational Excellence

Own strategic technical direction and execution of multi-quarter roadmaps for your platform area.
Define reliability, security, and operational standards that meet enterprise-grade expectations.

Deep technical expertise across Xometry's core stack: Python (backend services, APIs), React/TypeScript (frontend), and AWS cloud infrastructure.
Deep, hands-on fluency with modern AI development tools (AI coding assistants, agentic dev tools, AI-assisted code review), with a demonstrated ability to use them to compress delivery timelines and to coach others in adopting them effectively.
Significant experience with system architecture, microservices design, and distributed systems, particularly systems that operate cleanly across multiple teams or organizational boundaries.
A track record of introducing architectural patterns that get adopted as organizational standards, not just single-project fixes.
Excellent communication and collaboration abilities, comfortable engaging with both technical and non-technical stakeholders, from junior ICs to executives, across geographies and time zones.
