Stefan-Mihnea Lovas

Hardware Engineer working on the development of medical devices such as drug delivery systems, insulin pens, blood glucose meters, autoinjectors, and imaging equipment. I design hardware, solve complex technical problems, support new product launches, and worked on cost-reduction initiatives. Key achievements & responsibilities: * Worked on a major VAVE project for a mammograph system, achieving 25% cost reduction through PCB/function merging, redesign for manufacturability, and component optimization (ICs, IGBTs, motors, power supplies). * Created the Troubleshooting Guide for a new device entering market launch, helping field engineers diagnose hardware/software issues efficiently. * Led customer complaint investigations, identifying root causes (Ishikawa, structured problem-solving) and communicating directly with customers. * Performed bring-up & Electrical Verification (EV) for early-phase hardware, ensuring correct functionality and compliance with requirements. * Conducted risk assessments and DFMEAs, driving design improvements early in development. * Worked extensively with battery-powered devices: charge/discharge (CV, CC, CP), battery analysis, and power budget validation. * Proposed validated component alternatives during global shortages to ensure continuity of supply. * Supported production teams, collaborated with Firmware, Mechanical, Quality, and ATE teams, and mentored new colleagues. * Skilled with oscilloscopes, spectrum analyzers, battery testers, Cadence OrCAD 17.4, LTspice.

During my internship in the R&D Medical division, I supported hardware development activities for medical devices while completing both my bachelor’s and master’s degree projects. This role gave me hands-on experience with design, testing, documentation, and early-phase validation. Key responsibilities & achievements: * Assisted hardware engineers in development projects, performing BOM analyses, comparison reports, block-diagram reviews, and early bring-up / EV (Electrical Verification) tests. * Developed my Bachelor’s project, an electronic system that simulates an invasive glucometer and sends glucose values via Bluetooth. * Designed the schematic, BOM, power budget, and PCB. * Created Gerber files and delivered a fully functional prototype. * Completed my Master’s project focused on improving wireless inductive charging efficiency in low-power applications by identifying and validating technical optimization methods. * Gained practical experience with lab equipment such as oscilloscopes, spectrum analyzers, and battery testers, as well as CAD/design tools (OrCAD 17.4, LTspice). * Supported senior engineers with documentation, testing, and technical investigations across multiple ongoing medical device projects.
