Principal Analog Design Engineer

Role Overview 

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. 

What You’ll Do 

• 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 

What We’re Looking For 

• 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 

Nice to Have 

• 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, Power related 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
