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!
We are hiring a Sr. Staff hardware / Software Photonic Simulation Engineer. The selected candidate will partner with external facing teams at Lightmatter and the internal engineering team to deliver groundbreaking products to the market. As a Photonic Simulation Software Engineer, you will develop electo-optic simulation methodology that predicts the performance of our hardware. This will require a solid understanding of state-of-the-art simulation software, multiple programming languages, and clear communication skills.
In this role, you will focus on the development and maintenance of simulation tools across digital, analog, and photonics domains. This role involves working with 1) device models from the aforementioned domains; 2) multiple simulators, including Xcelium, Spectre, and scattering parameter simulators; and 3) programming languages such as VerilogA and Python.
You will work closely with our digital, analog, photonic, and software teams. We are particularly looking for someone with expertise in architecting digital circuits to enable high-speed AMS circuits, with a strong preference for someone with experience in photonic circuits.
Join a tight-knit team where each individual's contributions directly influence the success of the company and product. You'll have the opportunity to build a new kind of (super)computer from the ground up and to solve groundbreaking challenges along the way. Work with people who love to build and who thrive in technically diverse environments where great ideas are prioritized.
Responsibilities :
- Develop, enhance, and maintain models in digital, analog, and photonics domains.
- Integrate, enhance, and maintain a mixed-signal framework built on top of multiple simulators (e.g., Xcelium, Spectre, and scattering parameter simulators)
- Write and maintain code in VerilogA and Python to support modeling and simulation in multiple domains.
- Develop automated testbenches and verification scripts using the cocotb framework (preferred).
- Work closely with cross-functional teams, including design engineers, verification teams, and photonics specialists, to understand tool requirements and deliver effective solutions.
- Provide technical support and troubleshooting for simulation tools, addressing issues promptly to minimize downtime.
- Analyze and optimize simulation performance, ensuring tools run efficiently and accurately.
- Implement enhancements to improve simulation speed, accuracy, and resource utilization.
- Create and maintain comprehensive documentation for tool development processes, user guides, and technical specifications.
- Conduct training sessions and workshops to educate team members on tool usage and best practices.
- Stay updated with the latest advancements in simulation technologies, programming languages, and industry best practices.
- Propose and implement improvements to existing tools and workflows to enhance productivity and quality.
