I korthet

Define, design, and develop photonic integrated circuits for next-generation silicon photonics platforms targeting high-speed optical interconnect and DWDM transceiver applications. The role involves photonic device design, simulation, collaboration with cross-functional teams, and utilizing script-based workflows with AI for automation. Post-fabrication characterization and correlation with simulation are key aspects.

Ansvarsområden

  • 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 the 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.

Krav

  • 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.
  • Bachelor's degree in Electrical Engineering with 3+ years of experience designing RF/Analog circuits for wireless products (e.g., LNA's, PLL's) and 2+ years of ASIC design, verification, or related work experience.
  • OR Master's degree in Electrical Engineering or related field and 2+ years of ASIC design, verification, or related work experience.
  • OR PhD in Electrical Engineering or related field.
  • 2+ years of academic or professional experience using two or more of the following software: CADENCE, Virtuoso, ADS.

Önskade kvalifikationer

  • 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.

Förmåner

  • Competitive annual discretionary bonus program
  • Opportunity for annual RSU grants
  • Highly competitive benefits package designed to support your success at work, at home, and at play.
