Sr. Simulations Engineer, III-V Devices

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.

Simulation Mastery: Expert-level proficiency in Ansys Lumerical (FDTD, MODE, DEVICE, INTERCONNECT), Synopsys RSoft/OptSim , and Zemax/Speos .

RF & Mathematical Tools: Experience with Keysight ADS, Ansys HFSS , or CST Microwave Studio . Advanced proficiency in Python or MATLAB for automation and large-scale data analysis.

III-V & Semiconductor Physics: Deep understanding of bandgap engineering, carrier dynamics, recombination mechanisms, and band structures.

Fabrication & Packaging: Strong knowledge of how epitaxy growth, etching profiles, and metalization affect optical modes. Familiarity with fiber coupling and Co-Packaged Optics (CPO).

Analytical Thinking: Ability to synthesize large datasets and utilize statistical tools (e.g., JMP or Minitab) for performance reporting.

Communication: Proven ability to present complex technical trade-offs to engineering teams, executive leadership, and customers.

Problem Solving: Strong troubleshooting skills in resolving discrepancies between modeled and measured device performance.

Education: M.S. or Ph.D. in Physics, Electrical Engineering, Material Science, or a related field with an emphasis on computational photonics.

Experience: 5-10 years of industrial experience in photonics simulation and design, with a proven track record of bringing products from concept through in-house manufacturing.

Environment: Temperature-controlled office/lab setting.

Physical: Constantly viewing high-resolution monitors for prolonged periods (8+ hours) for detailed modeling.

Travel: Anticipated travel is less than 5%.
