Responsibilities

• Collaborate across a multidisciplinary team...

Cloud cost management is one of the biggest challenges organizations face today. As cloud adoption continues to accelerate, so do the complexities and costs associated with it — and macroeconomic conditions only increase pressure to prove cloud efficiency. That’s why we built CloudZero: a SaaS platform at the intersection of next-generation cloud cost management and FinOps. CloudZero ingests billing and usage data from all cloud, SaaS, and PaaS providers, organizes it in real time according to our customers’ business structures, lets customers view it at any level of time or resource granularity, and empowers cloud business optimization.

To date, we’ve raised over $52 million from leading venture capital firms across the country. We’re solving problems of massive scale, business importance, and complexity in a space that needs it more than ever. In 2023 and 2024 we won the New England VC “Hottest Start-Up” award and “Boston’s Best Places to Work” List. We are...

Sr. Staff Software Engineer, System Simulation Lead

Lightmatter builds chips for artificial intelligence computing. Our architecture leverages unique properties of light to enable fast and efficient compute engines and interconnects. If you're a collaborative engineer or scientist with a passion for innovation, solving challenging technical problems, and doing impactful work like building the world's first optical computers, consider joining the team at Lightmatter!

Lightmatter’s technology creates unique computational, communication, and system elements, from photonic systolic arrays to switches to heterogeneous wafer-scale computer systems. Lightmatter and its customers plan to use these elements to build very large and efficient compute clusters. Machine learning is a core target workload.

The System Simulation Lead will be responsible for leading a team that simulates these systems at many levels, generating insight into both current product...

Sr. Staff Software Engineer, Network Architecture

Lightmatter is redefining what computers and human beings are capable of by delivering a fundamentally new kind of computer that calculates using light. Transistors, the workhorse of modern computers, aren't improving at the rate they once were. To scale AI, companies are building increasingly large and energy-expensive data centers, a path that is neither financially nor environmentally sustainable. By delivering ultra-high performance and energy efficiency, 

Lightmatter’s technology allows the construction of systems on a massive scale. Lightmatter systems can support numerous high-radix and reconfigurable network topologies with combined fiber optic and on-wafer communication channels. 

We are looking for talented software engineers to help Lightmatter and our customers understand, optimize, and deploy these networked systems. In this role, you will be responsible for exploring various...
