Principal RF and Analog Design Engineer

Job title: Principal RF and Analog Design Engineer

We are seeking a Principal RF and Analog Design Engineer to design, integrate, and characterize high-performance RF and analog circuits for next-generation products. This role requires deep hands-on expertise, strong system-level understanding, and the ability to technically lead complex mixed-signal designs from concept through silicon qualification and production. You will work closely with digital, layout, validation, firmware, and product teams to deliver robust, manufacturable solutions for demanding RF and analog applications.

Responsibilities:

• Design, simulate RF and analog circuit blocks, including LNAs, mixers, and VCOs/PLLs.
• Develop data converters (ADCs/DACs); bias generation, bandgap references, LDOs.
• Design baseband amplifiers and filters; translate system-level requirements (noise, gain, linearity, power, phase noise) into robust circuit implementations.
• Perform detailed schematic design, simulation, and optimization across PVT corners.
• Collaborate with system architects to define RF signal chains and analog subsystems; drive tradeoff analyses between performance, power, area, and cost.
• Support RF budgeting (NF, IP3, phase noise, jitter, spur); participate in silicon signoff and characterization.
• Work with layout engineers on floor planning, sensitive routing, EM/IR/substrate issues; coordination of block-level and top-level signoff (AC/DC, noise, stability, yield).
• Lead silicon bring-up, lab characterization, debugging; correlate measurement results with simulation; identify root causes and drive fixes; support yield and ramp.
• Provide technical leadership; define best practices; mentor junior engineers; influence roadmaps; act as technical contact across cross-functional teams.

Qualifications:

• Bachelor’s, Master’s, or PhD in Electrical Engineering or related field.
• Typically 10+ years of hands-on RF and/or analog IC design experience.
• Proven tape-out ownership and silicon success.
• Strong understanding of RF fundamentals (noise, linearity, matching, phase noise).
• Analog circuit design techniques.
• CMOS/BiCMOS device physics.
• Experience with Cadence Virtuoso, SpectreRF, ADS, EMX or equivalent.
• Comfortable working across process nodes and foundries.
• Desired: Strong DSP fundamentals.
• Desired: Mixed-signal integration experience (RF + digital SoC).
• Desired: High-speed or precision analog experience.
• Desired: Familiarity with packaging, test, and manufacturing constraints.
• Desired: Experience supporting volume production.
• Soft Skills: problem-solving and debugging; ability to communicate complex technical concepts clearly; ownership mindset with attention to detail; collaborative and pragmatic approach to engineering tradeoffs.

Nice to Have:

• Experience with additional lab automation and test equipment.
• Familiarity with packaging, test, and manufacturing constraints in volume production environments.
• Prior exposure to RF/mixed-signal verification methodologies beyond the core tools.
