DescriptionWe are now looking for an outstanding Principal Solution Architect to join our team. The role’s primary responsibility is to work collaboratively with customers in architecting the next generation of super computers and machine learning systems enabled by Lightmatter’s photonic interconnect technology Passage.
In this role, you will work closely with Tier 1 Semiconductor companies and Cloud Service Provider organizations that are defining the next generation of scale out, HPC, and machine learning systems. You will be working cross functionally within Lightmatter as you define an optimal technical solution. Additionally, you will be collaborating with customers who are domain experts in HPC and ML system architectures to refine these designs based on their application requirements. You should be comfortable supporting deep technical discussions focused on interconnect topologies and how to scale HPC/ML architectures in 1024+ node systems. Excellent interpersonal skills and the ability to work independently are essential to being successful in the role.
Responsibilities
Partner with Lightmatter sales leaders to develop strong relationships with key technical stakeholders, and help them optimize their system architecture by taking advantage of Lightmatter’s interconnect technology
Be a domain expert in high performance computing (HPC) and machine learning system architectures with a focus on high-performance interconnects
Leverage background in HPC/scientific computing algorithms to identify performance bottlenecks related to interconnect and optimize topologies to improve performance
Apply extensive knowledge in high-performance interconnect topologies and function as an expert and principal advisor
Define new and refine existing ideas and design concepts that address scaling HPC and ML system architectures using Lightmatter’s highly disruptive interconnect technology Passage
Explains advanced concepts in HPC/ML system architecture and understands how those concepts relate to other disciplines.

10+ years of work-related experience in a high-tech electronics industry in a system design role or technical customer support role.
Experience defining the system architectures of high-performance compute clusters focused on HPC and/or ML workloads
Customer facing skill set and background as well as the ability to communicate effectively with customers
Action-oriented with strong analytical and problem-solving skills
Strong time-management and organization skills for coordinating and prioritizing multiple projects and initiatives
Excellent written and oral communications skills with the ability to effectively interface with management and engineering
Strong team-working and interpersonal skills
Preferred Qualifications
C/C++ and Python programming skills
Master's or PhD in related science or engineering field
High Performance Computing & Networking
Experience architecting systems with computational accelerators and high-performance interconnects (e.g., NVLink, Infiniband, etc...)
Proficiency profiling scientific computing, and/or machine learning workloads to identify performance bottlenecks related to networking, storage, and compute.
Company DescriptionLightmatter is leading the revolution in AI data center infrastructure, enabling the next giant leaps in human progress. The company invented the world’s first 3D-stacked photonics engine, Passage™, capable of connecting thousands to millions of processors at the speed of light in extreme-scale data centers for the most advanced AI and HPC workloads.
Lightmatter raised $400 million in its Series D round, reaching a valuation of $4.4 billion. We will continue to accelerate the development of data center photonics and grow every department at Lightmatter!
If you're passionate about tackling complex challenges, making an impact, and being an expert in your craft, join our team of brilliant scientists, engineers, and accomplished industry leaders.
Lightmatter is (re)inventing the future of computing with light!
