Job description

Electrical/Optical SerDes Analog Mixed Signal Design Engineer

Category: Chip Design

Location: Irvine, CA

Experience: More than 2 years work experience

Job Description

The Interconnect Solutions team is searching for qualified candidates to join our fast‑growing team. As a member of this dynamic team, you will work on state‑of‑the‑art next generation electrical and optical transceivers for data centers serving cloud infrastructure as well as the growing field of AI and high‑performance computing. We are looking for ambitious analog and mixed‑signal designers with exposure to silicon photonics and electro‑optical systems who are willing to learn, grow, and contribute to a diverse portfolio of high‑speed interconnect products. Architecture study and evaluation of advanced high‑speed SerDes and optical transceiver topologies targeting 100G/lane PAM4 and beyond, including EIC/PIC partitioning and link‑budget definition. Design and verification of high‑speed, high‑performance analog and mixed‑signal circuits including, but not limited to: modulator drivers (MRM/MZM/EAM), TIAs, front‑end circuits, samplers, comparators, ADCs, DACs, PLLs, CDRs, clock distribution, heater drivers, and bias DACs. Electro‑optic system modeling and co‑simulation with PIC designs, including behavioural modeling of photonic devices (MRM, MZM, EAM, PD, heaters, laser sources) in Verilog‑A, MATLAB, or Python. Collaborate with package and SI/PI teams to define and sign off EIC‑to‑PIC interface, bump map, and supply distribution for co‑packaged and advanced‑packaging contexts. Partner with DSP and algorithm teams on TX/RX equalization partitioning (analog CTLE/FFE/DFE vs. digital DSP) and link adaptation. Evaluate, measure, and debug silicon with firmware and test teams through bring‑up and post‑silicon validation until it reaches high‑volume production.

Main Requirements and Qualifications

• MS or above with a major in EE, Applied Physics, or a related field; PhD preferred.
• Solid background in high‑speed analog CMOS circuit design in advanced process nodes.
• Good understanding of deep‑submicron/FinFET process technology.
• Familiarity with serial links, wireline transceivers, or optical transceiver design and verification.
• Hands‑on experience with silicon photonic devices or electro‑optical transceivers: MRMs, MZMs, EAMs, PDs, grating couplers, heaters, lasers, etc.
• Understanding of optical transceiver design and system‑level requirements, including OMA, ER, TDECQ, RLM, BER, FEC, RIN, shot noise, chirp, dispersion, and optical nonlinearity.
• Proficient with Cadence design environment and mixed‑signal simulation.
• Proficient in MATLAB and/or Python for modeling, signal processing, and design automation.
• Able to assume responsibility for a variety of technical tasks and to work independently.
• Excellent working attitude and good interpersonal and communication skills.

Preferred Qualifications

• Experience developing behavioural or compact models of photonic devices (MRM, MZM, EAM, PD) in Verilog‑A/Verilog‑AMS for mixed‑signal co‑simulation.
• Experience with Lumerical (INTERCONNECT/FDTD/MODE).
• Exposure to CPO or pluggable optical transceiver architectures, thermal/wavelength control loops, and hardware/firmware partitioning of calibration and tracking.
• Experience with PIC‑level design and integration using foundry photonic PDKs.
• Experience with lab bring‑up of high‑speed or electro‑optical silicon.

Salary & Compensation

Salary range: $150,000 – $301,000. Employee may be eligible for performance bonus, short‑term and long‑term incentive programs. Actual total compensation will be dependent upon the individual's skills, experience and qualifications.

MediaTek provides a variety of benefits including comprehensive health insurance coverage, life and disability insurance, savings plan, company‑paid holidays, sick leave, vacation time, parental leave, 401K and more.
