Full Stack Engineer

Full-Stack 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 growing and deploying with major enterprises across insurance, travel, and technology. If you want to build infrastructure that the next decade of enterprise AI runs on, we'd love to talk.

About the Role

As a Full-Stack Engineer at zaimler, you'll work across the stack to design and implement features that power how users interact with context, data, and AI systems in production. You'll collaborate closely with backend, platform, and ML engineers to translate complex system behavior into intuitive, reliable product experiences.

This is a hands-on role with real ownership; you'll help shape both the architecture and the user experience of a core platform used by engineers.

What You'll Do

• Build End-to-End Product Features: Design and implement features across frontend applications and backend services, from APIs and data models to user-facing interfaces.
• Develop Scalable Backend Services: Build and maintain backend services that support product functionality, focusing on correctness, performance, and long-term maintainability.
• Craft Thoughtful Frontend Experiences: Create intuitive, responsive user interfaces that expose complex system behavior in a clear and usable way.
• Collaborate Across Teams: Work closely with platform, data, and ML engineers to understand system constraints and translate them into cohesive product experiences.
• Own What You Ship: Take features from idea to production, including testing, deployment, monitoring, and iteration based on real-world usage.
• Improve Developer & User Experience: Help refine APIs, tooling, and UI patterns to make the platform easier to understand and faster to use.

What We're Looking For

• 4+ years of experience building production software across the stack
• Strong experience with backend development (e.g., Python, Go, Java, or similar)
• Experience building modern frontend applications (e.g., React, TypeScript)
• Familiarity with API design, data modeling, and service-oriented architectures
• Comfort working with cloud environments (AWS, GCP, or Azure)
• Experience collaborating closely with product and engineering teams
• Ability to reason about system tradeoffs and make pragmatic engineering decisions

Nice to Have

• Experience working on data-heavy or developer-facing products
• Familiarity with distributed systems or ML-adjacent platforms
• Experience with Kubernetes or containerized environments
• Exposure to observability, performance tuning, or production debugging
• Interest in AI systems, infrastructure, or developer tooling

Why Join

• Work on foundational infrastructure powering production AI systems
• High ownership and direct impact on product direction
• Small, senior team with deep systems experience
• Opportunity to shape both architecture and user experience from early days
• Full benefits package (Medical, Dental, Vision, 401k).
• We sponsor H-1B visas and assist with immigration processes.

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.
