About the role
- Mesh Optical Technologies was founded on the belief that optical photons will be at the center of advanced technologies in the coming century. Making advanced technology ubiquitous means building at scale, and that's exactly what we're doing at Mesh.
- Our optical hardware platform requires tightly integrated high-speed electronic and photonic systems operating at tens of gigahertz and beyond—modulator drivers, trans-impedance amplifiers, SerDes interfaces, and the analog signal chains that connect them. We are seeking a High-Speed Mixed-Signal Design Engineer to architect, design, and validate the
Responsibilities
- Design and analyze high-speed analog and mixed-signal circuits for electro-optic systems, including modulator drivers, TIAs, CTLEs, limiting amplifiers, and clock/data recovery circuits
- Develop and own circuit-level and system-level models for high-speed signal chains, incorporating device parasitics, package effects, and photonic component behavior
- Perform transistor-level simulation and verification using industry tools (e.g., Cadence Virtuoso, Spectre, ADS, HFSS) across process corners, temperature, and supply variation
- Lead or contribute to chip-to-package-to-board co-design, including high-speed interconnect design, SI/PI analysis, and signal integrity closure from die through PCB
- Collaborate with PIC designers to co-optimize electro-optic performance across the driver-modulator and photodetector-TIA interfaces
- Analyze measurement data and correlate to simulation models, driving root-cause investigation and design iteration
- Partner with manufacturing and test engineering teams to develop production test methods for high-speed electrical and electro-optic assemblies
Requirements
- 3+ years of experience in high-speed analog, mixed-signal, or RF circuit design, with emphasis on circuits operating at multi-GHz bandwidths
- Experience with circuit simulation tools (e.g., Cadence Spectre, ADS, HFSS, or equivalent)
- Experience with high-speed lab characterization, including use of high-bandwidth oscilloscopes, VNAs, BERTs, and spectrum analyzers
- Working knowledge of semiconductor device physics and IC fabrication processes (CMOS, SiGe BiCMOS, or III-V)
- Familiarity with DSP concepts relevant to optical links (e.g., FFE, DFE, CTLE equalization) and optical performance metrics (e.g., OSNR, OMA, receiver sensitivity)
- Experience with electromagnetic simulation for high-speed interconnects and packaging (e.g., HFSS, Momentum, CST)
- Experience with photonic-electronic co-design or co-simulation (e.g., Lumerical Interconnect, VPI, ADS co-simulation)
- Experience working with silicon photonics or III-V electro-optic platforms
- Familiarity with reliability and qualification testing for high-speed electronic or electro-optic assemblies
- Master's or PhD in electrical engineering, applied physics, or a related discipline
- Strong foundation in analog and RF circuit design principles, including small-signal and large-signal analysis, noise analysis, and stability
- Understanding of high-speed serial link architectures and signaling formats (e.g., NRZ, PAM4, coherent modulation)
- Strong programming and data analysis skills (e.g., Python, MATLAB) for simulation automation, data processing, and visualization
- Willingness to work extended hours and weekends as needed
Nice to have
- Experience designing high-speed circuits for optical communications, including modulator drivers, TIAs, or SerDes front-ends
- Experience with high-speed package and interconnect design, including wirebond, flip-chip, or co-packaged optics integration
Compensation
- High-Speed Mixed Signals Design Engineer: $140,000.00 - $190,000.00/per year
- Title and base salary are determined on a case by case basis commensurate with experience and merit.
- In addition to base salary, compensation for this role includes:
- Paid parental leave and flexible PTO (3 weeks accrued vacation and 10 company holidays per year).
- Relocation assistance to sunny Los Angeles.
Benefits
- Eligibility for long-term incentives including company stock options and discretionary bonuses awarded for exceptional achievements.
- Comprehensive medical, vision, and dental insurance with significant cost covered by the company for yourself and dependents.
- Paid parental leave and flexible PTO (3 weeks accrued vacation and 10 company holidays per year).
- 401(k) retirement plan access.
