• Collaborate with customers, product engineering, manufacturing engineering, quality, supply chain, sales, and program management teams to achieve technical, commercial, and program objectives.
• Lead design reviews, technical risk assessments, DFMEA activities, and engineering decisionmaking processes to ensure products meet performance, manufacturability, reliability, cost, and quality objectives.
• Design and develop speed and position sensing solutions, including Variable Reluctance (VR), Hall-effect/active, and Magnetic Resistive (MR) sensor technologies.
• Develop and evaluate magnetic circuit designs including pole-piece geometry, magnet selection and placement, flux-path optimization, and target/tone-wheel interactions to achieve required sensing performance.
• Analyze and optimize sensor performance including signal amplitude, waveform quality, zero crossing accuracy, timing performance, speed response, air-gap sensitivity, tolerance stack-up effects, and operation across temperature and environmental conditions.
• Develop and evaluate active sensor architectures incorporating Hall-effect and MR integrated circuits, including analog and digital signal processing, filtering, output interfaces, noise mitigation, timing performance, temperature stability, and EMC considerations.
• Support coil and electrical design activities, including turn count, resistance, inductance, signal conditioning requirements, and tradeoff analysis between output amplitude, response characteristics, and system performance.
• Design and optimize sensor packaging, encapsulation, and sealing solutions utilizing injection molding, transfer molding, low-pressure molding, overmolding, potting, and related manufacturing processes to ensure product durability and environmental protection.
• Select and evaluate materials based on thermal performance, coefficient of thermal expansion (CTE), chemical compatibility, mechanical durability, and the effects of mechanical stress and thermal expansion on sensor performance.
• Plan, execute, and interpret prototype evaluations, design verification (DV), production validation (PV), and environmental testing activities using laboratory and data acquisition equipment to validate product performance and reliability.
• Assess and validate system-level performance including signal-to-noise ratio (SNR), timing accuracy, jitter, drift, electrical robustness, and environmental durability under customer-specific operating conditions.
• Lead and support root-cause investigations and corrective actions related to development issues, validation failures, manufacturing concerns, and field returns; correlate laboratory results with design, process, and application variables.
• Support Design for Manufacturability (DFM), Design for Reliability (DFR), APQP, PPAP, and production launch activities, including resolution of launch-related technical issues and transition of products into volume manufacturing.
