Job Description

Ring is looking for a System Power Engineer who will be a part of our global electrical engineering team, playing a critical role in ensuring the highest product quality standards and driving continuous improvement for the products.

As a member of the Power Engineering team you will develop and test power solutions for our next generation Doorbell/Camera hardware. You will be a power electronics subject matter expert in an engineering team responsible for both new product development as well as product sustaining and support. You will help grow the capabilities in our power test lab by creating/running new tests, innovating new test processes, and automating the execution of these tests.

This is a fast-paced, intellectually challenging position, and you’ll work with thought leaders in multiple technology areas. You’ll have high standards for yourself and everyone you work with, and you’ll be constantly looking for ways to improve products performance, quality and cost.

You must be responsive, flexible and able to succeed within a fast-paced environment. You are expected to represent as the Power Design owner and dive deep into the difficult problem for the root cause analysis and arrange appropriated solution for it.

Key job responsibilities
Power Architecture & Design
. Define system-level power architectures (block diagrams, schematics, PDN design) from concept (RFQ) through mass production, ensuring compliance with safety (IEC/UL/FCC) and thermal requirements.
. Design and validate power circuits, including DC-DC converters (buck/boost/forward), battery charging systems, and low-noise LDOs for IoT devices.

Testing & Validation
. Develop test plans/specifications for power integrity, efficiency, thermal performance, and compliance (EMI/EMC, safety, CE/FCC).
. Automate test workflows using Python/MATLAB and lab equipment (oscilloscopes, power analyzers, thermal chambers) to accelerate prototype validation.

Problem Solving & RCA
. Lead root cause analysis (RCA) for power anomalies, collaborating with firmware, thermal, and manufacturing teams to implement hardware/software fixes or approved workarounds.
. Troubleshoot complex issues in power sequencing, voltage droops, and transient response under dynamic loads.

Component & Supply Chain
. Execute component qualification programs, including stress testing, second-source vendor evaluation, and cost-reduction initiatives.
. Optimize power, performance, and cost (PPC) trade-offs across the product lifecycle.

Compliance & Documentation
. Ensure designs meet global safety, regulatory, and reliability standards (IEC, UL, CE).
. Author technical documentation, design reviews, and test reports for internal and external stakeholders.

Basic Qualifications

- Experience designing, testing, and debugging power electronics such as AC/DC and DC/DC power conversion, switching power supplies, driver circuits, and battery systems

Preferred Qualifications

- Experience designing or testing products for safety, compliance, and regulatory standards
- Experience in working with overseas CM/OEM/ODM vendors in product development
- In-depth experience in Doorbell, Camera and other IoT product development
- Knowledge of IoT infrastructure constraints including power tree, power budget and battery life estimation
- Ability to apply critical thinking in complex situations; experience working in cross functional groups including mechanical engineering, thermal engineering, test, reliability, and failure analysis.
- Cross-organizational communication – comfortable evangelizing ideas and concerns clearly and persuasively, in both verbal and written forms.
- Experience with power, performance and cost optimization
