Job description

Responsibilities

• 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

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, 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

Compensation

Pay range: 175,000 – 350,000 USD per year (San Jose (HQ))
