Help Companies Work Better with AI Build something that matters. Right now, over 5,000 companies, from DAX enterprises like Merck to fast-growing startups, use Langdock every day. Their employees open our product to draft strategies, analyze documents, automate workflows, and think through hard problems with AI.

We are the platform that makes this possible: secure, model agnostic, and deeply integrated with how work actually happens.

What "Agent Engineer" Means Here AI agents are becoming the operating system of how companies work. Not chatbots. Not simple automations. Agents that own tasks end-to-end: reading customer tickets, updating CRMs, delegating subtasks to other agents, and knowing when to escalate to a human.

At Langdock, we are building both the product that lets our customers deploy agents and the internal infrastructure that runs our own. This role sits at that intersection. You will design, build, and operate the AI agents that power critical parts of Langdock's operations, from customer support automation to internal workflows. And the patterns you develop will directly inform how we build the agent platform for thousands of other companies.

This is not a role where you configure tools built by someone else. You will work across the full stack: prompt engineering, orchestration protocols, integrations, reliability, and cost management. You will own agents the way an engineer owns a production service.

What You Will Actually Do

• Own production agents end-to-end. You design, deploy, monitor, and improve the AI agents that handle real customer interactions and internal workflows. When an agent misbehaves, you dig into the logs to identify the root cause and fix it. When it works beautifully, that is also you.
• Build and operate customer support automation. You will monitor Langdock's support experience by supervising agents that resolve issues faster than most humans could, while knowing exactly when to hand off.
• Manage agent reliability, cost, and quality. You track how agents perform, what they cost, where they fail, and why. You set budgets, tune behavior, adjust governance rules, and make sure every agent earns its keep.

What Makes This Different This role barely existed two years ago. There is no playbook for it. You are building the discipline of "agent operations" at a company that is also building the platform for it.

The agents you run will directly reach Langdock's 5,000+ customers, meaning your work has an immediate, measurable impact. And because the patterns you develop internally become the patterns we productize for customers, you are not just operating agents. You are defining how agents should be operated.

We went from 2 to 20M+ ARR in one year. You will join early enough to shape how things work, but late enough that we have traction, customers, and a product people love.

You will also learn fast. Our team is small, the scope is large, and the feedback loops are short. People who joined a year ago are now running critical functions. If you are good, you will grow.

You Might Be a Fit If...

• You have built and maintained AI agents or automations in production.
• You are deeply technical. You understand LLMs, token economics, prompt engineering, API design, and orchestration patterns. You can read a protocol spec and immediately see the edge cases.
• You obsess over experimentation and reliability. You think in terms of error rates and customer satisfaction. You instrument everything.
• You are not precious about your agents. When one fails, you find the root cause and fix it. When a simpler approach works better, you kill the clever one.
• You do not just use AI tools daily. You actively nerd about your setup. You experiment with different models, prompts, workflows, and automations. You have strong opinions about what works and why.
• You would rather own a problem than be told exactly what to do.

The Environment We work from our office in Berlin, Greifswalder Strasse 212. Everyone works together in person because the hardest problems get solved faster at a whiteboard than in a Slack thread. Conversations happen faster, problems get solved quicker, and we actually know each other.

Days start at 8:30. Lunch & dinner are together. We run, go to the gym, and take care of ourselves. Health is not separate from work here, it is part of how we work well.

The vibe is calm but intense. No one is yelling or panicking. But everyone is working hard on things that matter.

Compensation Salaries are transparent and tied to levels, not negotiation. All roles include equity.

We will figure out the right level together based on your experience and scope. Levels are about the work you own, not your title or years of experience. We narrow down the expected salary range early in the process.

Next steps We move fast. Most processes complete within two weeks.

If this sounds like your kind of work, we would like to meet you.
