Mechanical Engineer

Design and develop mechanical components, assemblies, and enclosures for Cerillo's microplate reader product family using 3D CAD software. Create detailed engineering drawings with proper GD&T tolerancing in accordance with ASME Y14.5 standards. Lead prototype development including hands-on fabrication, assembly, and iterative testing of mechanical subassemblies. Define and execute mechanical testing protocols to validate structural integrity, thermal performance, sealing, and environmental robustness. Collaborate with electrical and optical engineers to integrate PCB assemblies, optical paths, and illumination systems into compact, precise enclosures. Design fixtures, jigs, and tooling to support assembly, calibration, and quality control on the production floor. Drive design for manufacturability and design for assembly, working with contract manufacturers to optimize part geometry, material selection, and tolerances for scalable production. Manage relationships with external vendors, machine shops, and injection molding suppliers; obtain and evaluate quotes and lead times. Maintain complete and accurate design documentation including SolidWorks models, drawings, BOMs, and ECOs within a PDM/PLM system. Troubleshoot mechanical issues identified during development, testing, or production; implement and document corrective design changes. Support regulatory documentation and risk management activities as required. Contribute to new product concept development and product roadmap planning. Perform ad-hoc engineering tasks as directed by the Chief Executive Officer and/or Engineering leadership.
