Inductive Power Transfer DSP Engineer (Wireless Power)

Summary

Posted: Mar 13, 2025

Role Number:200594458

The Wireless Power Technology team is pioneering new ways of charging your devices. Our flagship product’s name, the MagSafe charger, says it all. It is magnetic, it charges fast, and above all, it is safe! Bringing all these aspects together requires careful orchestration of electromagnetism, passive and active electronics, state-of-the-art safety algorithms, communication over inductive links, and, of course, an appealing product design. Our products touch millions of lives each day… with consistency and dependability. We adhere to rigorous, data-driven engineering principles to ensure optimal performance in every conceivable scenario. We are looking for a hands-on digital signal-processing (DSP) architect who will design, integrate, and ship next-generation communication architecture for inductive charging products. The successful candidate will have a strong grasp of electrical engineering fundamentals, including DSP, digital communication, and analog/power circuits. They will be eager to learn and explore new domains, particularly wireless charging. Proficiency in simulation and modeling tools (SPICE, MATLAB, C, Python) is essential. Collaboration with system-integration teams will be crucial for the successful productization of these technologies.

Description

• Develop and own analog/digital simulation models of communication modules • Predict bit error-rate and packet error-rate estimates using simulation models • Participate in the development of innovative, new digital communication architectures for inductive links • Author engineering requirements specification and drive cross-functional product execution • Validate hardware/firmware implementation across full range of user operating conditions • Troubleshoot and analyze failures throughout the product development cycle

Minimum Qualifications

• Experience in developing applications in DSP or digital communication applications is required and hands-on hardware bring-up and debugging (e.g., digital filters, FFT, sampling theory, modulation schemes, DSP/MCU, fixed-point implementations, algorithms)
• Scripting and software tools — MATLAB, Python, C
• BS and a minimum of 3 years relevant industry experience

Preferred Qualifications

• BS or MS in electrical engineering
• Experience using bench equipment in the lab (e.g., oscilloscopes, spectrum analyzers, power supplies)
• Basic circuits and circuit simulations (e.g., RLC circuits, op-amps, ADC, diodes, FET’s, SPICE, Cadence)
• Experience authoring technical documentation, architectural trade-off analysis, and executive presentations.
