We are looking for a highly experienced **Senior Firmware Engineer **with deep expertise in charger architectures, PMIC integration, and battery-powered embedded systems. If you have built product firmware around complex power management and enjoy working at the intersection of hardware and low-level embedded software, this role is for you.
This is a hands-on individual contributor role within our global Firmware team. You will contribute to power management and charging firmware development across our product portfolio, including both core devices and accessory products. The role spans the full development and device lifetime pipeline—from early prototyping and hardware bring-up through NPI, mass production, factory support, and long-term sustaining in the field.
Power management and charging performance are foundational to product reliability and user experience. In this role, your work directly influences battery life, charging behavior, safety, manufacturability, and long-term durability across multiple product categories—from early development to years in the field.
**What you will do: **
- Develop power management Firmware: Design, implement, debug, and optimize firmware for battery charging systems, PMIC integration, power sequencing, and charging interfaces across multiple product categories. Ensure solutions meet safety, efficiency, and performance requirements in real-world conditions.
- Contribute to the Full Power Management Stack: Participate in the development and evolution of the complete power management firmware stack, including low-power state handling, battery management, charger negotiation, and system-level power transitions.
- Engage Across the Full Product Lifecycle: Contribute from early architecture discussions and hardware bring-up through NPI validation, manufacturing ramp, and post-launch sustaining. Support firmware releases, field issue investigations, and continuous improvements throughout the lifetime of shipped devices.
- Hands-On Hardware Bring-Up & Debugging: Work directly with schematics, datasheets, specifications, and lab equipment to implement and debug board-level and system-level power and charging designs.
- Develop Low-Level Drivers & Platform Ports: Implement and maintain device drivers for PMICs, chargers, and related subsystems. Contribute to firmware porting across MCU platforms and firmware update mechanisms to ensure safe and reliable factory and field updates.
- Manufacturing & Factory Support: Develop factory test firmware, contribute to defining manufacturing test specifications, and troubleshoot issues during hardware builds and production ramp.
- Cross-Functional Collaboration: work closely with hardware, product, program management, and manufacturing teams as a key system level technical contributor in the power and charging domain.
- Optimize for Power and Reliability: Design firmware architectures that balance device performance, power consumption, and user experience, especially for always-on, battery-constrained wearable devices.
- Contribute to Strategy: Play a key role in strategic decisions related to firmware architecture and technology stack, aligning with our mission to revolutionize the wearable technology industry.
**Requirements **
We would love to consider you for this role if you have:
- 5+ Years of Firmware Development experience:** **With strong hands-on development experience in battery-powered consumer electronics or other high-volume embedded systems including
- Battery & Low-Power Optimization Experience: Demonstrated experience optimizing power states, wake-up flows, power transitions to maximize battery life, battery qualification processes and development.
- Agile Development Practices: Comfortable working in an agile development environment, with excellent collaboration and communication skills to work effectively with teams across different locations.
- Hardware-Level Debugging Skills: Comfortable using oscilloscopes, power analyzers, logic analyzers, and other lab tools to root-cause complex charging and power issues.
- Manufacturing & Production Support Exposure: Experience supporting factory firmware releases, ramp activities, and troubleshooting production issues.
- Strong System-Level Thinking: Ability to understand interactions between hardware, firmware, and manufacturing processes across the full product lifecycle.
- Education: Bachelor’s or Master’s degree in Electrical Engineering, Computer Science, or related field.
