About zaimler
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.
The Role
As a Technical Lead, you’ll sit at the intersection of technical execution, architecture, and leadership.
This is a hands-on role. You’ll write code, own systems, and lead our growing team of engineers, helping us ship production-quality infrastructure while setting a high bar for engineering rigor as we scale.
You are not a project manager. You are a builder who can lead.

Technical Leadership
Own the design and implementation of core backend/platform systemsLead architecture discussions and make pragmatic tradeoffs in ambiguous environmentsSet technical direction for a small team while staying deeply involved in the codebaseReview PRs with an eye toward correctness, performance, and long-term maintainabilityDrive technical decisions across data, infra, and application layers as needed
Team Leadership
Manage and mentor a small group of engineers Provide regular feedback, coaching, and growth guidanceHelp onboard new engineers and set expectations for technical excellenceFoster a culture of ownership, velocity, and thoughtful engineering
Execution & Delivery
Break down complex problems into clear milestonesBalance speed with system quality in a fast-moving startup environmentPartner closely with product and leadership to align technical work with company goalsIdentify risks early and proactively unblock the team
What We're Looking For
