Sr. Simulations Engineer, Silicon Photonics

Skorpios Technologies•Temecula, CA

10d•Hybrid

About The Position

Skorpios Technologies, Inc. are innovators in heterogeneous integration of silicon photonic technology and semiconductor development. The company is rapidly expanding the technical organization and seeking Sr. Simulation Engineers specializing in Optical and Photonics modeling. These roles are critical in developing the next generation of disruptive III-V and Silicon Photonics integrated products. The Sr. Simulation Engineer is responsible for high-fidelity modeling and simulation of complex photonic integrated circuits (PICs). You will lead the virtual prototyping of high-performance devices—including lasers, modulators, and passive optical components—ensuring designs are optimized for Skorpios’ unique technology platform. Operating with an in-house foundry, these roles serve as the essential bridge between theoretical physics and rapid hardware implementation.

Requirements

Expert-level proficiency in Ansys Lumerical (FDTD, MODE, DEVICE, INTERCONNECT), Synopsys RSoft/OptSim, and Zemax/Speos.
Experience with Keysight ADS, Ansys HFSS, or CST Microwave Studio.
Advanced proficiency in Python or MATLAB for automation and large-scale data analysis.
Ability to synthesize large datasets and utilize statistical tools (e.g., JMP or Minitab) for performance reporting.
Proven ability to present complex technical trade-offs to engineering teams, executive leadership, and customers.
Strong troubleshooting skills in resolving discrepancies between modeled and measured device performance.
M.S. with 10+ years’ experience or Ph.D. in Physics, Electrical Engineering, Material Science, or a related field with an emphasis on computational photonics.
Photonics simulation and design, with a proven track record of bringing products from concept through in-house manufacturing.
Must be a 'U.S. person' within the meaning of ITAR (U.S. Citizen, U.S. Permanent Resident, Political Asylee, or Refugee).

Responsibilities

Design and simulate III-V and Silicon Photonics components, including DFB/DBR Lasers, SOA, active and passive design of Silicon Photonics components such as MZM modulators, optical couplers, WDM devices, and 90-degree hybrids.
Lead complex modeling that couples optical, electrical, and thermal solvers (e.g., self-heating effects in laser diodes).
Optimize RF performance for high-speed modulators and optical-electrical conversion efficiency.
Partner directly with the internal Fab and Device Designers to translate simulations into actionable layouts.
Establish process design rules and perform DRC (Design Rule Check) and LVS (Layout Versus Schematic) to ensure tapeout accuracy.
