Fullstack AI Engineer

CLAR AI deploys agentic AI systems into real businesses (logistics, ops, healthcare) to solve high-stakes challenges. We are looking for a Fullstack AI Engineer to join as one of the first engineers, shaping the stack, UX standards, and delivery speed. The role involves designing and developing frontend and backend features, building agentic UX, and shaping platform infrastructure.

• Develop Features End-to-End: Work shoulder-to-shoulder with Forward Deployed Engineers to build technology that allows new customer-facing features with everything from database models to APIs and UI components.
• Design Agentic UX: Design and build human-in-the-loop controls, monitors, and configuration surfaces that make AI agents intuitive to use. You wire up LLM inference, retrieval, tool/agent orchestration, and evals to launch and productionize new AI integrations into our platform.
• Backend APIs and Integration: Design backend services and clean, typed interfaces with strong observability and CI/CD. Your services function as robust connectors into customer systems and power agentic logic as well as frontend experiences.
• Shape Platform and Infrastructure: Evolve our design system, shared repos, and developer tooling by turning one-offs into libraries, patterns, and platform primitives to compound speed and quality - shaping both our product roadmap and the technical DNA of the company.

• You have strong engineering foundations and quickly write clean, production-ready code. You’re comfortable spinning up full-stack web applications from scratch (e.g. in React, Typescript and NodeJS or Python) and building rich, performant frontends and backend logic to power them.
• You move comfortably across the stack from data flows and APIs to polished UIs and deployment/ops. You understand how relational data structures, and component architecture shape product experience. You’ve built and owned features end-to-end.
• You think like an AI engineer, knowing where AI belongs (and where it doesn’t). You build on top of foundation models and understand combining model capabilities with retrieval, voice AI, multi-agent architectures, external tools etc. You’re excited about designing new abstractions for reasoning, memory, and interaction - the emerging blocks of agentic software.
• You lay the groundwork for tomorrow’s platform. You enjoy figuring out how a feature, interaction, or model capability can evolve into a reusable system through clear, composable code that is easy for others to build on.

• Foundational Impact: This is a rare opportunity to shape a company from day one. Your decisions matter, and you will see the immediate impact of your work.
• Competitive Package: We want you to think and act like an entrepreneur. That's why you receive an equity stake in the company's success - paired with a strong salary.
• Ambitious Work, Serious Fun: We're a group of solid people you'll actually enjoy seeing on a Monday and believe the journey should be as fun as the destination.
