Role Description As an Analog Design Engineer at Tylsemi, you will design and deliver high-performance analog and mixed-signal circuits that enable robust, manufacturable silicon. This role spans a wide experience range (5–30 years) and is ideal for engineers who combine strong fundamentals with practical execution—translating system requirements into silicon-ready designs, validating performance across corners, and partnering closely with layout, verification, test, and product teams to drive first-time-right outcomes. - Own end-to-end analog block development: requirements definition, architecture, transistor-level design, simulation, and signoff - Design and optimize analog/mixed-signal circuits such as amplifiers, references, biasing, regulators (LDO/DC-DC support), comparators, oscillators/clocking, data converters (as applicable), and sensor/AFE front ends - Drive performance across PVT corners, mismatch/Monte Carlo, aging/reliability considerations, and realistic loading/interaction with surrounding blocks - Partner with layout to guide floorplanning, matching/guarding strategies, parasitic-aware design, and post-layout closure (PEX) - Develop and maintain testbenches, modeling collateral, and documentation to enable efficient verification and integration - Support silicon bring-up and debug: correlate lab data to simulations, root-cause issues, and implement design fixes or ECOs - Collaborate cross-functionally with digital, firmware, DFT, validation, and product engineering to ensure system-level success - Contribute to design methodology improvements: reusable circuits, checklists, signoff flows, and best practices that scale across programs Qualifications - 5+ years of experience in analog or mixed-signal IC design (scope and ownership aligned to experience level) - Strong fundamentals in analog circuit design, device physics, noise, stability/compensation, and feedback systems - Proficiency with industry-standard EDA tools and simulation flows (e.g., Spectre/HSPICE, ADE, waveform/debug tooling) - Experience closing designs through post-layout parasitics and across process/voltage/temperature corners - Ability to translate ambiguous system needs into clear block requirements and executable design plans - Strong debugging skills and comfort working with lab/validation teams to correlate silicon to simulation - Clear communication and high ownership in cross-site, cross-functional environments Requirements - Experience with high-speed or precision analog (low-noise, low-offset, high-linearity) depending on product needs - Background in power management (LDOs, bandgaps, references, protection, start-up, transient response) - ADC/DAC, PLL/clocking, or SERDES-adjacent analog experience - Familiarity with reliability/ESD considerations and design-for-manufacturability practices - Experience supporting production ramp: yield learning, characterization, and test correlation Success in This Role Looks Like - Analog blocks meet spec with margin across PVT, mismatch, and post-layout effects - Design reviews are crisp: requirements, tradeoffs, and risks are clearly articulated and managed - Silicon bring-up converges quickly through strong correlation, structured debug, and decisive fixes - Cross-functional partners (layout, verification, test, validation) can execute efficiently with clear interfaces and documentation - Reusable design collateral and improved methodology reduce cycle time and increase first-pass success
