Job Purpose

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.

Core Responsibilities

• Material & Heterogeneous Integration: Optimize epitaxy layers and quantum well designs. Perform optical mode and impedance matching across diverse material interfaces to ensure seamless III-V and Silicon integration.
• In-House Foundry Collaboration: 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.
• Virtual DOE & Validation: Execute virtual Design of Experiments (DOE) to predict device reliability and performance. Validate simulation outputs against internal lab characterization data to refine material parameters and "close the loop" on model accuracy.

Requirements

Technical Stack & Knowledge Domains

• 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).

Competencies

• 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.

Required Education and Experience

• Education: M.S. or Ph.D. in Physics, Electrical Engineering, Material Science, or a related field with an emphasis on computational photonics.
• Experience: 5+ years of industrial experience in photonics simulation and design, with a proven track record of bringing products from concept through in-house manufacturing.

Physical Demands & Work Environment

• 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%.

Work Environment

Work is primarily performed in a temperature-controlled, open cubicle setting. Frequent interruptions and conversational noise can be expected. This role may also require occasional work in a manufacturing or cleanroom environment.

Work Authorization/Security Clearance Requirements

Authorization may be required to release covered technology to employees who are not U.S. citizens, U.S. nationals, lawful permanent residents, asylees, or refugees.

Compensation and Benefits

Skorpios embraces a Total Compensation philosophy that includes a base salary and eligibility for overtime for non-exempt roles.

We offer a comprehensive and competitive benefits package designed to support employee health, welfare, and retirement. Highlights include healthcare benefits, a 401(k) savings plan, and paid time off.

Expected salary range: $160,000-210,000, depending on education, qualifications and experience.

The actual starting rate will be determined based on role-related criteria, including educational qualifications or equivalent experience, relevant work history, and the skills required for the role.
