Senior Audio IC Design Engineer (Class-D / Power + Signal Chain)

Location: Redmond, WAComp: $160K-200K base + benefitsCompany: Stealth-mode product builds + Tier1 partnershipsWhat this role actually isIf you've designed real audio silicon (not just blocks on paper) and taken at least one chip to silicon + bring-up, this is your lane. You'll own audio-centric analog/mixed-signal IC design end-to-end, especially:Class-D / audio amplifier architecturesPower + analog signal chain (ADC front-end, regulators, biasing)Silicon debug when things don't behave like your sims said they wouldThis is not a narrow "block owner" role. It's for engineers who can go from architecture > transistor > layout > interaction > lab bench > fix > ship.What you'll actually doDesign audio IC blocks from scratch (Class-D, analog front-end, PMIC elements)Build robust analog/mixed-signal circuits (bandgaps, POR, regulators, comparators)Run real simulations that matter: PVT, Monte Carlo, post-layoutOwn silicon bring-up and lab characterizationSolve power + efficiency challenges in audio systemsPartner closely with layout, validation, and customersYou're a strong fit if youHave 6+ years in analog/mixed-signal IC designWork comfortably at the transistor level (CMOS)Have shipped at least one tapeoutHave hands-on experience with:Audio ICs (Class-D preferred)OR adjacent high-performance analog signal chainsKnow your way aroundCadence Virtuoso + SPICE (Spectre/HSPICE)PVT, mismatch, noise, stability analysisHave done silicon debug in the lab scope analyzers real measurementsBonus points (but not required)Low-power / high-efficiency design experienceVerilog-AMSPython or MATLAB for automationWhat makes someone stand out hereYou've personally debugged failing silicon and fixed itYou understand audio performance tradeoffs deeply (efficiency vs THD vs noise)You can move between system thinking and transistor-level detail easilyYou don't wait for specs, you help define themWhy this team600+ engineers globally, deep silicon + product expertiseStrong engineering culture (low ego, high ownership)Work on real shipped products in consumer/connected devicesTight, collaborative US team with global backingBenefitsCompetitive base salary and overall compensation packageFull benefits: Medical, Dental, Vision401 (K) with generous company matchGenerous Paid time off (PTO)Vacation, sick, and paid holidaysLife Insurance coverageOpportunity to work on cutting-edge technology projects
