The ideal candidate brings deep experience architecting embedded hardware, with a strongtrack recordof takingproductsfrom early concept through validation, manufacturing, and deployment.

This role spans the full embedded hardware lifecycle—from early system architecture through schematic capture, PCB layout, validation, and production support. As a Staff Engineer, you will help shape technical direction, guide design decisions thatimpactmanufacturability and reliability, and collaborate closely with multidisciplinary teams toproductizesystems where power efficiency, physical footprint, RF performance, and robust communication are critical.

This position requires US Citizenship.

Job Responsibilities:

• Architect, design, and deliver embedded PCBs integrating microcontrollers, SoCs, sensors, and power management circuits
• Provide technical ownership of schematic capture and PCB layout, balancing electrical performance, RF considerations, mechanical constraints, and manufacturability
• Lead board bring-up, debugging, and validation of prototype and production hardware using oscilloscopes, logic analyzers, spectrum analyzers, and related lab equipment
• Drive hardware through verification, qualification, and release to manufacturing, supporting multiple product revisions as needed
• Support system-level integration, test strategy development, and root-cause analysis of field or manufacturing issues
• Define and implement digital interfaces such as I²C, SPI, UART, USB, GPIO, and wireless interfaces
• Collaborate closely with firmware engineers to ensure reliable hardware/software co-design and integration
• Support rapid prototyping, iterative board revisions, and design-for-manufacture (DFM) and design-for-test (DFT) activities
• Establish andmaintainclear documentation for hardware designs, test procedures, and revision history to support product lifecycle needs
• Participate in and lead design reviews, contributing to system architecture and long-term platform decisions
• Mentor andprovidetechnical guidance to other engineers on embedded and RF hardware best practices
• Contribute to R&D efforts to evolve core technology capabilities and transition them into shipped products

Preferred Skills and Experience:

• 9+ years of experience designing, debugging, anddeployingembedded hardware products from concept through production
• Demonstrated ownership of hardware that has entered manufacturing or fielded use
• Proficiencywith schematic capture and PCB layout tools (e.g., Altium Designer,KiCad, OrCAD)
• Strong understanding of PCB design best practices for signal integrity, power distribution, grounding, EMI/EMC, and mixed-signal layouts
• Hands-on RF experience, such as integrating wireless modules, designing RF signal paths, antennas, or supporting RF validation and tuning
• Experience using high-speed lab equipment (e.g., spectrum analyzers, VNAs, high-bandwidth oscilloscopes)
• Experience integrating microcontrollers, SoCs, sensors, wireless modules, and power management into compact, low-power designs
• Deep familiarity with embedded interfaces and protocols (I²C, SPI, UART, USB, GPIO)
• Experience collaborating with firmware teams on complex hardware/software integration and debugging
• Working knowledge of DFM, DFT, and manufacturing workflows with contract manufacturers
• Strong documentation and communication skills, with the ability to clearly explain design decisions and tradeoffs
• Ability tooperateindependently, take initiative, and provide technical leadership in small, fast-moving teams
• Comfortable working on ambitious, early-stage technologies with evolving requirements and tight iteration cycles
