## Description

Where Europe's enterprises adopt AI Langdock is the AI platform used by more than 10,000 companies to give employees secure access to the leading AI models, to build and share agents and to automate repetitive workflows. We have grown past $40M ARR while remaining a small team, and we care deeply about operating efficiently across the entire company. For many enterprises, Langdock is becoming the place where most of the net-new work is produced. As people and agents create more documents, analyses, decisions, and automations inside AI interfaces, the context and data behind that work accumulate within Langdock. This gives us the opportunity to earn a larger role in their technology stack by building a platform they choose to rely on. Our ambition is to build that platform for European enterprises while preserving their control over data, model providers, and deployment environments. We have made meaningful progress at the application layer, but much of the foundation beneath it still needs to be built. You can watch the Meet the engineering team video to get a feeling for how we work. The role Product Engineers own a customer problem and its outcome from discovery through production. You speak with users, decide what the product should do, build the solution across the stack, ship it, and use production feedback to determine what happens next. Being close to users gives you substantial product-shaping power. You are expected to distinguish the underlying need from the initial request, form a point of view, and make decisions about scope, interaction, architecture, and sequencing. The role is measured by what changes for users and the business, not by how many tickets move to done. We like the way Linear builds product: a clear point of view, fast iteration, and a consistently high standard in the final software. We want the same care and coherence in a more complex setting, where AI behavior is probabilistic and enterprise requirements are part of the product rather than an afterthought. What you might work on Product Engineers turn new AI capabilities into products that fit how enterprises actually work. This includes evolving our core products, inventing new interaction models for people and agents, making probabilistic systems understandable and governable, and bringing those capabilities into the tools and workflows customers already use. Chat and Agents. Evolve the core Langdock experience where people work with models and agents. Design how users provide context, work with files, call tools, create and share agents, and turn model output into completed work. The product must make streaming responses, tool execution, latency, and failure feel clear and dependable without exposing users to the complexity underneath. New interfaces for agentic work. Design how people steer multi-step work, review intermediate results, approve actions, edit outputs, and recover from failure when established interface conventions do not exist yet. This includes moving beyond chat toward interfaces for producing documents, analyses, applications, and other structured work together with agents. Making agents trustworthy at enterprise scale. Build governance and evaluation capabilities that help workspace administrators discover, test, approve, configure, and manage agents without making them harder for employees to use. Product questions include how to compare agent versions, diagnose regressions, manage permissions, and introduce control at scale without slowing down experimentation. Organizing the work agents produce. Develop Library, the system that brings attachments, generated outputs, and connected knowledge together across Langdock. Help people and agents find the right context, understand where information came from, reuse previous work, and preserve permissions as content moves through the platform. Automating long-running work. Extend Workflows, where agents call tools, pause for human input, produce structured outputs, retry safely,
