Converts conversations into executable workflows
Our mission: Putting AI to work. We’re not making another “AI app”; we’re fundamentally changing how work gets done. We deploy agentic AI systems into real businesses (logistics, ops, healthcare) to solve high-stakes challenges with our proprietary platform. We believe this is the biggest technological shift since the internet, and we’re building the company to define it. Following significant early traction, we are expanding our team.
We are a team hungry to build, and our culture is the engine that drives us. We care deeply about outcomes and hold ourselves accountable to both speed and quality of craft. We work on-site in the heart of Munich, believing proximity breeds serendipity - the unscripted breakthroughs and high-trust collaboration that forge our supportive culture and world-class results.
We are looking for a Fullstack Engineer to join our team as one of the first engineers shaping our stack, UX standards, and delivery speed from day one. You will be designing and developing frontend and backend software features and establish tech stack choices and API standards to build our growing agentic platform.
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 are a curious, pragmatic, and product-minded engineer who thrives on making real things work end-to-end. You care deeply about speed, the elegance of your code and the value it delivers to users - and you’re motivated by the idea of shaping not just a product, but an entirely new category of software.
Software Engineering: 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.
Builder at Every Layer: 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.
AI Native: 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.
Platform Instinct: 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.
You need a detailed roadmap and clearly defined tickets to be productive.
You’re uncomfortable working in an environment where systems evolve quickly and patterns are still being established.
You see frontend, backend, or infrastructure as “someone else’s problem” rather than parts of one system.
You are looking for an established corporate environment and a 9-to-5 mentality.
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.
Significant Equity: 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.
Does this sound like you? Let’s put AI to work.
CLAR AI automates enterprise workflows by turning everyday conversations into actions executed inside a company’s existing systems, including tasks like updating records and completing processes, through channels employees and customers already use (voice, email, WhatsApp, Teams). Its product uses agentic AI to understand a business context by modeling products, customers, processes, and rules, so the AI can act like an experienced colleague. A governance layer checks actions against standard operating procedures, enforces user roles, and allows human oversight when needed, ensuring consistent, compliant execution without a new user interface. The goal is to scale repetitive requests, improve data quality from conversations, and boost operational efficiency and customer satisfaction while staying within the current software stack.
