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

Lead and scale Tacit’s software organization across consumer applications, real-time AI systems, cloud infrastructure, and R&D platforms. Recruit and develop engineers, establish technical priorities, drive architecture and execution, pioneer AI-native engineering workflows, and collaborate with ML, hardware, firmware, and product teams to deliver advanced consumer products.

Validate, debug, and improve electrical systems for next-generation sensing hardware from prototype through production. Responsibilities include board bring-up, analog, digital, power, and mixed-signal characterization; root-causing hardware issues; schematic and PCB updates; automated bench testing; reliability, yield, and statistical analysis; and collaboration with firmware, software, mechanical teams, and contract manufacturers.

Electrical Engineering Intern supporting prototype sensing hardware validation, board bring-up, bench measurement, debugging, and root-cause analysis. Responsibilities include testing power rails, battery charging, sensor front ends, and digital interfaces; proposing schematic and layout improvements; automating bench tests; analyzing multi-board data; and documenting findings. The role offers exposure to the product lifecycle from prototype development through mass production.

Build polished, user-facing interfaces for novel human-computer interaction workflows using React and TypeScript. Translate product concepts and designs into intuitive UX flows, prototype and test experiences, improve onboarding and session journeys, analyze user behavior, and establish frontend patterns and component systems. The role emphasizes accessibility, performance, responsiveness, motion, visual quality, and close collaboration across design and engineering.

Hands-on RF hardware internship focused on characterizing RF signal chains and bringing up transceiver evaluation hardware. Work includes prototyping circuits, designing PCBs and test fixtures, using lab instruments (VNA, spectrum analyzer, signal generator), developing automated test setups with Python and embedded C/C++, analyzing measurement data, and producing validation procedures and engineering recommendations. Interns own focused projects and collaborate with RF and validation engineers onsite in San Francisco.

Design, implement, and optimize embedded firmware and NPU/DSP runtimes for on-device ML. Build realtime sensor-to-inference pipelines, optimize latency, memory, and power, debug hardware/firmware interactions, and collaborate with ML, electrical, and product teams to deliver production-grade edge intelligence.

Lead architecture and transistor-level design for ultra-low-power, frequency-agile CMOS RF sensing. Define RF front-end, synthesizer, and power-management approaches; stand up RFIC design flows; simulate and design critical blocks; manage tape-out, bring-up, and external partners; and build the internal silicon team and IP strategy.

Develop and optimize deep learning models to decode multimodal biosignals from custom sensors for real-time inference on edge hardware. Build neural architectures, fusion techniques, evaluation frameworks, and collaborate with hardware engineers and neuroscientists to deploy and benchmark models across users and datasets.

PhD-level internship to design, simulate, prototype, and test antenna systems. Duties include EM simulations, PCB layout support, measurement with RF test equipment, prototype integration, on-body characterization, and documentation to support product development and manufacturability.
