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.\nJob Purpose\nThe 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.\nCore Responsibilities\nActive & Passive Device Modeling: Design and simulate III-V components, including DFB/DBR Lasers, SOAs, EAM/MZM modulators, UTC photodiodes.\n Multi-Physics & RF Simulation: 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.\n 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.\n 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.\nRequirements\nTechnical Stack & Knowledge Domains\nSimulation Mastery: Expert-level proficiency in Ansys Lumerical (FDTD, MODE, DEVICE, INTERCONNECT), Synopsys RSoft/OptSim, and Zemax/Speos.\nRF & 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.\nIII-V & Semiconductor Physics: Deep understanding of bandgap engineering, carrier dynamics, recombination mechanisms, and band structures.\n Fabrication & Packaging: Strong knowledge of how epitaxy growth, etching profiles, and metalization affect optical modes. Familiarity with fiber coupling and Co-Packaged Optics (CPO).\nCompetencies\n Analytical Thinking: Ability to synthesize large datasets and utilize statistical tools (e.g., JMP or Minitab) for performance reporting.\nCommunication: Proven ability to present complex technical trade-offs to engineering teams, executive leadership, and customers.\nProblem Solving: Strong troubleshooting skills in resolving discrepancies between modeled and measured device performance.\nRequired Education and Experience\nEducation: M.S. or Ph.D. in Physics, Electrical Engineering, Material Science, or a related field with an emphasis on computational photonics.\nExperience: 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.\nPhysical Demands & Work Environment\nEnvironment: Temperature-controlled office/lab setting.\n Physical: Constantly viewing high-resolution monitors for prolonged periods (8+ hours) for detailed modeling.\n Travel: Anticipated travel is less than 5%.\nSalary Description\n160,000 - 210,000","description_format":"text","description_chars":3594,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Hardware","Manufacturing","Optical Communications"],"lifecycle":[{"event":"open","at":"2026-10-01T10:41:09Z"}],"visa":[],"liveness":{"score":72,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.797,"p_room":0.9,"age_days":26,"expected_fill_days":38,"reasons":["conf:2","win:mid"],"computed_at":"2026-10-20T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/skorpios-technologies-inc-sr-simulations-engineer-iii-v-devices","json_url":"https://alion.io/job/skorpios-technologies-inc-sr-simulations-engineer-iii-v-devices.json","meta":{"generated_at":"2026-10-20T12:26:45Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":13705,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":3791990},"rest":"https://alion.io/mcp/rest/get_company?id=3791990"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fskorpios-technologies-inc-sr-simulations-engineer-iii-v-devices"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fskorpios-technologies-inc-sr-simulations-engineer-iii-v-devices"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fskorpios-technologies-inc-sr-simulations-engineer-iii-v-devices"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/skorpios-technologies-inc-sr-simulations-engineer-iii-v-devices\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fskorpios-technologies-inc-sr-simulations-engineer-iii-v-devices"}]}
