Top Tech Jobs & Startup Jobs in San Francisco Bay Area, CA

Design and develop reusable wireless software libraries and embedded system infrastructure supporting Bluetooth, UWB, NFC, and related technologies. Integrate wireless chipsets through I²C, SPI, UART, USB, and GPIO; collaborate across hardware, firmware, operating systems, and product teams; debug hardware-software interactions; optimize memory, CPU, power, and latency; validate new platforms; investigate field issues; influence architecture; and mentor engineers.

Design and prototype AI-powered digital experiences, interfaces, and features. Create user flows, wireframes, prototypes, and polished visual designs using tools such as Figma and Origami Studio. Present concepts, participate in design reviews, collaborate with software, hardware, and product partners, and contribute to design systems, interaction patterns, reusable components, iconography, and visual standards. Explore emerging AI technologies and experimental interaction models.

Develop and maintain firmware and embedded system architecture for ARM-based MCUs, focusing on low-power, radio stacks (BT/BLE/Wi‑Fi), sensors, and audio pipelines. Perform hardware bring-up and lab debugging, collaborate with cross-functional teams (EE, RF, Security, Cloud, AI), manage performance metrics (memory, power, latency), and coordinate vendors and manufacturing for production builds.

Lead RF system architecture, integration, and desense mitigation for wearable/mobile products across Wi‑Fi, Bluetooth, UWB and NFC. Define specs, run CST/ADS simulations, review PCB layouts, lead RF bring‑up and OTA/conducted validation, support certifications, mentor engineers, and drive cross‑functional RF performance decisions from concept through mass production.

Design and build performant, native Windows applications that surface AI-driven, context-aware experiences on-device. Lead architecture, integrate with AI and cloud services, collaborate with design and product, and prototype responsive UI interactions.

The Senior Software Engineer will design and maintain backend services and RESTful APIs, ensuring scalability and performance, while collaborating with team members across functions.

The Lead Software Engineer will design and implement scalable cloud-native systems, mentor engineers, and oversee cloud services delivery across multiple teams.

Lead power architecture and system-level modeling for wearable devices: build and correlate power models, define battery/charging profiles, design measurements and telemetry, and partner across product, hardware, firmware, and manufacturing to meet power targets.

Lead design and implementation of embedded device security across firmware, OS, and cloud interfaces. Perform threat modeling, architect hardware-backed identity and secure key management, implement TrustZone/TEE/kernel solutions, integrate biometric sensor security, and apply secure SDLC and vulnerability management practices across multi-disciplinary teams.

Provide executive-level support to the SVP, Design & Innovation, manage priorities, and ensure smooth operational processes for the Design team.
