Résumé du poste

Proper Voltage designs and builds safety-critical battery energy storage systems. This role leads the real-time control firmware for our bidirectional DC/DC power conversion stage, implementing compensators within a sub-microsecond ISR budget and proving on the bench that the silicon meets the design.

You will collaborate with the Lead Controls Engineer to ensure correct timing, fixed-point scaling, and safe-state transitions, owning the portable DC/DC control library across multiple MCU targets.

Qualifications

• Bachelor-level degree in EE/CE or equivalent demonstrated capability.
• 6+ years producing embedded firmware in C for RT systems.
• Experience with switched-mode power converters, inverters, or motor drives.
• Strong understanding of control fundamentals, discretization, and anti-windup.
• Fluency with PWM, ADC, DAC, DMAs and related peripherals.
• Deterministic ISR design and measurement of worst-case execution time.
• Ability to justify fixed-point vs floating-point decisions for timing.
• Proven lab capability with power hardware and measurement tools.

Responsabilités

• Implement compensators and control loops in C within fixed budgets.
• Verify firmware against models using closed-loop simulations.
• Architect and maintain the control ISR and scheduler with deterministic timing.
• Configure PWM, ADC, and trigger architectures with accurate timing.
• Measure and report timing, jitter, and worst-case execution time.
• Lead verification efforts for UL 1973/UL 1998/UL 9540 certifications.
• Lead power-conversion firmware reviews and port to multiple MCU targets.
