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.

Collaboration & Communication

What You'll Bring to Xometry:

• 12+ years of professional software development experience, with a proven track record of leading complex, multi-quarter initiatives.
• 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.

Why Join Xometry?

• Play a critical role in driving profitable growth and shaping the future of manufacturing through an AI-powered platform.
• Partner directly with executive leadership on high-impact strategic decisions, while founding and scaling a new engineering organization.
