Head of Engineering

Executive Summary

This candidate is a competent mid-level Ruby on Rails developer with 6+ years of experience but completely lacks the leadership experience, infrastructure expertise, and scale required for a Head of Engineering position. They have never managed teams, built infrastructure at scale, or demonstrated the technical depth needed for this executive role. This candidate is a role mismatch - they're applying for a C-level position with an individual contributor background.

Assessment Reasoning

NOT_FIT decision based on fundamental role mismatch. The candidate is an individual contributor developer applying for a Head of Engineering position requiring extensive leadership experience, high-scale infrastructure expertise, and team management skills. They lack experience with critical technologies (Kubernetes, Terraform, Rust, ScyllaDB) and have never operated systems at the required scale (3B+ requests/day). Most critically, there's no evidence of any leadership, management, or team-building experience. The salary expectation gap alone ($150k-$250k vs likely $80k-$120k market rate for their actual level) indicates misalignment with role requirements.
