Senior Frontend Engineer

AI agents can't reason over data they don't understand. Enterprise data today is fragmented across dozens of systems with no shared context, meaning, or structure, and that's why most enterprise AI is failing. The shift from copilots to autonomous agents is creating an entirely new infrastructure layer, and we're building it.

zaimler is the context infrastructure for the agentic era: a platform that automatically discovers domain knowledge, maps relationships, and gives AI agents the semantic understanding to operate with precision at scale. Imagine knowledge graphs that support real-time inference, built for systems that need to reason, not just retrieve.

zaimler was founded by Biswajit Das (ex-VP Engineering, Truera), a Data Infra veteran and former Chief Architect at Visa, and Sofus Macskassy (ex-Director of Engineering, LinkedIn), who built one of the largest knowledge graphs in production in the industry at LinkedIn. We're a small, senior team at the seed stage, deploying with major enterprises across insurance, travel, and technology. If you want to build infrastructure that the next decade of AI runs on, we'd love to talk.

As the Founding Product Engineer, you’ll play a crucial role in defining and building out the product experience for the Graph Semantic Layer. Your focus is to shape the product from inception to launch, working closely with our initial design partners.

As a core member of the team your work will have a direct impact on product direction and design decisions, owning the product lifecycle from user research to the final user interface. 

This role is ideal for someone with an entrepreneurial mindset who thrives in fast-paced, early-stage environments where you’ll wear multiple hats—leading both the technical implementation and contributing heavily to product strategy.

We value builders over résumés. If this role excites you but you don't check every box, we still want to hear from you. zaimler is an equal opportunity employer.
