Dwdm System Architect Jobs (NOW HIRING)

Company:
Qualcomm Atheros, Inc.
Job Area:
Engineering Group, Engineering Group > RFIC Design
General Summary:
Define, design, and develop photonic integrated circuits for next-generation silicon photonics platforms targeting high-speed
optical interconnect and DWDM transceiver applications. Perform photonic device design covering both active components
and passive components using 3D structure simulation tools and foundry PDKs.
Collaborate cross-functionally with other designers, and systems teams in a DWDM transceiver product project.
Utilize script-based workflow with AI to automate simulation, layout generation, and data analysis.
Work with testing engineers on post-fabrication device characterization in the lab to validate designs and close the loop between simulation and hardware.
Required for This Role:
- Bachelor's degree in EE, Physics, Optics, or related field with 5+ years of PIC design experience, OR
- Master's degree in EE, Physics, Optics, or related field with 3+ years of PIC design experience, OR
- PhD in EE, Physics, Optics, or related field with 1+ year of PIC design experiences.
- 2+ years hands-on with: Lumerical (FDTD, MODE, CHARGE, INTERCONNECT), and any layout editor/viewer (Cadence Virtuoso, KLayout, or equivalent), and Python.
- Hands-on design experience with silicon-photonics foundry PDKs
- System-level understanding of optical link budgets, DWDM channel plans, OMA/TDECQ, and transceiver power allocation.
Preferred Qualifications:
- 2+ years of Co-Packaged Optics (CPO) design experience - chip-to-chip optical coupling, CPO-specific constraints, or tape-out in a CPO-targeted node.
- 2+ years of PIC-EIC co-design - joint optimization for high-speed transceivers, including driver/TIA co-simulation with active photonic devices.
- System-level photonic simulation tools: VPI Photonics, Lumerical Zemax OpticStudio, or equivalent.
- DWDM wavelength control loops, thermal tuning, closed-loop resonance lock for ring-modulator transmitters.
- Track record of photonic tape-outs (MPW or full-reticle) with post-silicon characterization closure.
- Publication record or patent filings in integrated photonics.
Principal Duties and Responsibilities
- Design active (MRM, MZM, photodetectors) and passive (edge/grating couplers, power splitters, wavelength MUX/DEMUX) photonic devices
from spec through tape-out using foundry PDKs and 3D structure optical simulation.
- Perform 3D photonic simulation (FDTD, MODE, INTERCONNECT, and CHARGE for carrier/electro-optic effects) to validate device
performance and iterate to target specs.
- Develop and maintain script-based workflows - leveraging AI-assisted tooling - to automate parameter sweeps, layout
generation, and measurement-data processing.
- Review and sign off on PIC physical layouts produced by the dedicated layout engineer from physical design team.
- Collaborate with other PIC designers, EIC designers, and package teams to run co-simulations. Align interface specs, and validate electro-optical
performance in the full DWDM transceiver system.
- Execute and interpret post-fabrication characterization lab testing.
- Close the simulation-to-hardware loop by correlating characterization data with models and proposing corrections.
- Participate in cross-functional design reviews spanning component performance, tape-out readiness, and system link budget.
- Maintain internal technical documentation: design specs, simulation methodology, characterization reports, and tape-out checklists.
- Track silicon photonics, CPO, and DWDM transceiver developments, and apply emerging techniques to improve design quality and
time-to-tape-out.
Level of Responsibility
- Works under some supervision, with high independence for component-level design decisions.
- Provides technical guidance and layout-review feedback to layout engineers and junior team members.
- Owns design deliverables; errors may impact the tape-out schedule and require re-simulation or a re-spin.
- Communicates technical status, simulation results, and characterization findings to EIC designers, packaging engineers, and systems
architects.
- Works within the tape-out schedule, reticle area budget, and PDK constraints.
- Has meaningful influence on component-level architecture and platform-direction discussions.
- Completes multi-step tasks spanning simulation, layout, and characterization, and prioritizes parallel workstreams.
- Exercises engineering judgment when simulation, PDK, or characterization data is incomplete or conflicting.
- Applies inductive and deductive problem-solving to diagnose simulation-versus-measurement discrepancies.
EDA Tools
- Must: Lumerical (FDTD, MODE, INTERCONNECT), any layout editor/viewer (Cadence Virtuoso, KLayout, or equivalent), Python or equivalent
- Optional: MATLAB, VPI Photonics, Lumerical Zemax OpticStudio
