Jonas Cruz

Mechanical Engineer working on the development and validation of complex electromechanical systems for mission-critical defense applications. Experience in CFD and thermal modeling (Ansys Fluent), mechanical design (PTC Creo), and physics-based simulations (Python, MATLAB). Responsible for prototype development, verification & validation, and implementation of industrial telemetry systems for real-time performance monitoring.

Military officer responsible for leading and training teams in high-reliability operational environments. Managed the operation and troubleshooting of complex defense, communication and command-and-control (C2) systems where redundancy and operational continuity were critical. Enforced SOPs and risk management protocols, coordinating logistics, system deployment and operational readiness in demanding mission-critical scenarios.

Research assistant in experimental materials engineering, supporting investigations on residual stresses and hardness in steels using non-destructive testing techniques. Collected and monitored electromagnetic noise signals with specialized sensors and processed experimental data in MATLAB to support model validation. Worked in an international research environment applying rigorous experimental methodologies.

CNC operator responsible for high-precision machining using CNC and conventional equipment including lathes, milling machines and surface grinders. Developed and optimized G-code programs directly at the machine controller and independently prepared machines for production runs (tooling, fixtures, offsets and calibration). Performed dimensional inspection using precision metrology tools to ensure compliance with engineering tolerances.

Industrial maintenance mechanic responsible for diagnosing failures in pharmaceutical production machinery and restoring equipment functionality on the shop floor. Manufactured replacement parts using conventional machining (lathe, milling and drilling) and performed precision inspection to meet strict tolerance and hygiene standards. Conducted mechanical assembly and alignment to minimize downtime.
