Optical Simulation Engineer information

What is an Optical Simulation Engineer?

An Optical Simulation Engineer is a professional who uses specialized software and modeling techniques to design, analyze, and optimize optical systems such as lenses, lasers, and imaging devices. They simulate the behavior of light within these systems to predict performance and identify potential issues before physical prototypes are built. These engineers work closely with product development teams in industries like telecommunications, aerospace, automotive, and consumer electronics. Their expertise helps to improve efficiency, reduce costs, and ensure the quality of optical products.

What are the main challenges an Optical Simulation Engineer faces when working on multidisciplinary project teams?

Optical Simulation Engineers often collaborate closely with mechanical, electrical, and software engineers to ensure that optical designs integrate seamlessly into larger systems. A common challenge is translating complex optical requirements into terms that colleagues from other disciplines can understand, while also adapting simulations to reflect real-world constraints such as tolerances and material properties. Effective communication and flexibility are essential, as project requirements can evolve rapidly and may require iterative simulations or adjustments. Building strong cross-functional relationships can help overcome these challenges and lead to more robust, innovative solutions.

What is the difference between Optical Simulation Engineer vs Optical Design Engineer?

AspectOptical Simulation EngineerOptical Design Engineer
Required CredentialsBachelor's or Master's in optics, physics, or engineering; proficiency in simulation softwareBachelor's or Master's in optics, physics, or engineering; strong design and analytical skills
Work EnvironmentPrimarily uses simulation tools to model optical systems; collaborates with design teamsDesigns and develops optical components and systems; often involved in prototyping
Employer & Industry UsageOptics companies, research labs, aerospace, and defenseOptics and photonics companies, consumer electronics, and medical device industries

Both roles require a background in optics and engineering, but Optical Simulation Engineers focus on modeling and analysis using simulation software, while Optical Design Engineers are more involved in creating and optimizing physical optical systems. They often work together but have distinct responsibilities within the optical development process.

What are the key skills and qualifications needed to thrive as an Optical Simulation Engineer, and why are they important?

To thrive as an Optical Simulation Engineer, you need expertise in optics, physics, and mathematics, typically with a degree in optical engineering or a related field. Proficiency in simulation software such as Zemax, LightTools, or COMSOL Multiphysics, along with familiarity with programming languages like Python or MATLAB, is commonly required. Strong problem-solving skills, attention to detail, and effective communication are crucial for collaborating with interdisciplinary teams and conveying complex technical concepts. These abilities ensure accurate optical system modeling, efficient project workflows, and successful development of innovative optical products.

Job description

About Eridu
Eridu is a Silicon Valley-based hardware startup pioneering infrastructure solutions that accelerate AI data centers to deliver Faster AI. Today's AI performance is frequently limited by communication bottlenecks. Eridu introduces multiple industry-first innovations across silicon, packaging, software, and systems to deliver an order of magnitude improvement in performance and unlock greater GPU utilization to speed training job completion times and tokens-per-second for more profitable inference. We do this while simultaneously reducing capital and power costs and improving reliability.
The company's solutions and value proposition have been widely validated by leading hyperscalers.
Eridu has raised over $200M to date including its most recent, oversubscribed Series A round. The company is led by a veteran team of Silicon Valley executives who have delivered multiple billion dollar product lines and led multiple companies to billion dollar exits, including serial entrepreneur Drew Perkins, co-founder of Infinera (NASDAQ: INFN), Lightera (acq. by Ciena), Gainspeed (acq. by Nokia) and Mojo Vision (the world's leading micro-LED company). The company is in execution mode and has a world-class engineering team with decades of experience in state-of-the-art silicon, packaging, optics, software, and systems. Eridu is working with best-in-class supply chain partners including silicon, packaging and systems.

Position Overview
We are seeking a highly motivated Network Simulation Engineer to lead the simulation and analysis of AI communication workloads (e.g. collective communications) across various data center network topologies. In this role, you will apply network simulation tools to model real-world AI applications-including LLMs and DLRMs-to inform architectural decisions across Eridu's product development lifecycle and to showcase our value to prospective customers and investors.
You will collaborate cross-functionally with customers, ASIC designers, and simulation tool providers to optimize performance, influence design, and deliver transformative AI networking solutions.
Responsibilities
  • Model AI Workloads: Simulate communication patterns of distributed AI workloads (e.g., LLMs, DLRMs) across diverse network topologies to analyze performance and scalability.
  • Drive Architecture Optimization: Work with customers to evaluate their AI workloads and provide recommendations for topology design, protocol tuning, and system architecture.
  • Influence ASIC Design: Collaborate with the internal ASIC and architecture teams by providing simulation-based insights that shape chip design for optimized AI traffic flows.
  • Tool Development & Partnership: Interface with simulation tool providers (who have optimized versions of NS-3, ASTRA-sim, etc.) to customize, tune, and enhance modeling frameworks for Eridu's specific requirements and to operate these tools to run simulations.
  • Documentation & Communication: Create clear and compelling reports, documentation, and presentations to communicate insights to technical and non-technical stakeholders.
Qualifications
  • MSc or PhD in Computer Science, Electrical Engineering, or a related field with some specialization in AI/ML communications or equivalent hands-on experience
  • Strong experience with network simulation tools such as NS3, OMNeT++, or custom-built simulators.
  • Familiarity with distributed training frameworks (e.g., PyTorch, TensorFlow), collective communication libraries (e.g., NCCL, RCCL), and GPU programming (CUDA or ROCm).
  • Deep understanding of frontier model architectures, parallelism approaches and operational functionality
  • Deep understanding of Ethernet, InfiniBand, and high-performance data center networking technologies.
  • Solid grasp of AI system architecture, including compute, memory, and interconnect bottlenecks in large-scale training/inference clusters.
  • Strong programming skills in C++ and Python.
  • Clear and confident communication skills, both written and verbal.
  • 2+ years of relevant experience preferred; exceptional early-career candidates will also be considered.

Why Join Us?
At Eridu, you'll have the opportunity to shape the future of AI infrastructure, working with a world-class team on groundbreaking technology that pushes the boundaries of AI performance. Your contributions will directly impact the next generation of AI infrastructure solutions, transforming the performance of AI data centers.
The starting base salary for the selected candidate will be established based on their relevant skills, experience, qualifications, work location, market trends, and the compensation of employees in comparable roles.
