As a
** Sr. Principal Embedded Engineer**, you will act as a technical authority and engineering leader, responsible for architecting and delivering complex embedded systems across a diverse range of applications. This role combines deep technical execution with strategic leadership, including shaping technical direction, mentoring engineers, and driving system-level decisions across the full product lifecycle from concept development through production and sustainment.### Responsibilities
* Lead the architecture, design, and delivery of advanced embedded systems, including high-speed mixed-signal PCB design and embedded firmware.
* Own end-to-end product lifecycle execution, including requirements definition, feasibility analysis, system architecture, prototyping, validation, production release, and post-production sustainment.
* Design and develop multi-layer PCBs incorporating high-speed digital, analog, RF, and power electronics subsystems.
* Develop embedded firmware and platform software using C/C++, RTOS, and/or embedded Linux.
* Drive hardware/firmware/software integration, ensuring performance, reliability, and scalability in complex systems.
* Lead system-level technical decision making, including component selection, platform selection, trade studies, and risk mitigation.
* Guide design verification and validation, including unit testing, integration testing, compliance testing, and certification readiness (e.g., FCC, CE, UL).
* Serve as a technical leader and mentor, providing guidance, coaching, and technical oversight to multidisciplinary teams.
* Collaborate with cross-functional teams (mechanical, systems, software, manufacturing, controls) and external stakeholders to deliver integrated solutions.
* Support stakeholder engagement, including technical presentations, solution definition, and expectation management.
* Drive improvements in engineering processes, tools, and development methodologies to enhance execution quality and consistency.
* Oversee productization activities, including DFM/DFT, supplier engagement, production ramp, and field support.### Qualifications
* *
* Education:

** Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or related STEM field.
* *
* Experience:

** Typically 12+ years of experience in embedded systems engineering with demonstrated technical leadership.
* Deep expertise in:  + PCB design (high-speed digital, mixed-signal, RF, and power electronics)  + Signal integrity, EMI/EMC, and robust hardware design practices
* Strong embedded firmware experience in C/C++, with exposure to RTOS (FreeRTOS, Zephyr, RTX) and/or embedded Linux.
* Extensive experience with microcontrollers and embedded platforms (ARM Cortex, STM
32, NXP, TI, Silicon Labs, etc.).
* Strong working knowledge of communication protocols, including SPI, I2C, UART, CAN, Ethernet, USB, and wireless interfaces.
* Experience with version control systems (Git) and modern collaborative development workflows.
* Proven experience implementing unit testing, automated testing, and CI/CD workflows.
* Demonstrated success delivering complex products from concept through production and field support.
* Strong expertise in debugging and root-cause analysis using lab instrumentation (oscilloscopes, logic analyzers, spectrum analyzers).
* Excellent communication skills with experience working in customer-facing or cross-functional environments.
* Must be a U.S. citizen or national, U.S.…
