## Description

We are seeking a Mechanical Integration & Test Engineer to own the mechanical integration of machines, tooling, fixtures, and workstations across our production lines and development labs. Integration & Test Engineers at Mesh must have a working knowledge of design, manufacturing, and test operations across their domain. A successful engineer on this team demonstrates strong engineering intuition, critical thinking, and comfort working under ambiguous requirements with minimal oversight., * Own the mechanical integration of production equipment, tooling, fixtures, and workstations into high-volume manufacturing lines

 * Lead mechanical bring-up, debug, and ramp of new and modified production cells, resolving integration issues across mechanical, structural, and thermal boundaries
 * Define and maintain system-level mechanical interfaces between tools, fixtures, material handling systems, and factory infrastructure
 * Design, build, and qualify test fixtures, workholding, and mechanical hardware interfaces used for qualification, validation, and manufacturing
 * Evaluate proposed designs for manufacturability and mechanical integration, providing feedback on assembly sequence, access, tolerance stackups, and fixturing requirements
 * Develop and refine assembly procedures, integration sequences, and mechanical validation checklists based on build experience and lessons learned
 * Enable day-to-day execution of the mechanical integration and test flow on the production floor
 * Evaluate nonconformances to determine root cause and drive corrective action and system improvements
 * Maintain mechanical configuration of production lines, including tracking fixture revisions, tooling changes, and equipment modifications
 * Interface with both engineers and technicians to optimize manufacturing, assembly, and automation workflows
