Engineering Department (all applications) - m/w/d

Langdock

HELP US CHANGE THE WAY THE WORLD WORKS BUILD SOMETHING THAT MATTERS. Langdock exists to change the way the world works, bridging the gap between what technology can do and what people actually do with it. We bring all leading AI models into one secure, model-agnostic platform and make them usable across entire organizations. Over 6,000 companies use our platform every day, from fast-growing startups to some of Europe's largest enterprises. Their employees open Langdock to draft strategies, analyze documents, or automate workflows - helping them to work smarter, think more creatively, and reach their full potential. WHAT “BUSINESS” MEANS HERE Everyone in business at Langdock is technical. Not in theory, but in practice. You should be comfortable discussing APIs, building automations, and thinking in systems. Our business team does not work with AI. We rethink how work itself gets done with it. We design new AI powered workflows for ourselves and our customers, experiment with internal automations, and continuously refine how sales, operations, and customer success operate using our state-of-the-art products. We treat day-to-day work as an applied AI discipline. We have the following departments that we are hiring for: SALES You will take Langdock from first conversation to signed contract. Our customers are IT leaders, security teams, and executives at mid to large companies worldwide. The product sells well, but enterprise deals require someone who can navigate complexity, build trust, and close. PARTNERSHIPS You will build and own strategic relationships that expand Langdock's reach. This includes technology partners, consulting firms, system integrators, and ecosystem players who influence how AI is adopted. AI ADOPTION MANAGEMENT You will own the relationship after the sale: onboarding, adoption, expansion, renewal. When a customer succeeds with Langdock, that is your work. When they struggle, you figure out why and fix it. SOLUTIONS ENGINEERING You are the technical bridge. You understand APIs, integrations, and enterprise architecture well enough to spec implementations, answer hard questions in calls, and make sure what we promise actually works. OPERATIONS You will build the systems that let everything else run: applied AI, finance, legal, people ops, internal tools. At our stage, this means solving problems directly, not managing people who solve them. MARKETING You will tell Langdock's story: content, brand, events, demand generation. We are not interested in vanity metrics. We want marketing that drives pipeline and helps customers understand what we do. WHAT YOU WILL ACTUALLY DO The specifics depend on the function, but across all business roles: * Own outcomes, not activities. We do not measure hours or meetings. We measure results and efficiency getting there. * Work directly with customers. Even in ops or marketing, you will be close to the people who use our product. * Use Langdock constantly. We build AI tools for work. You will use them to do your work. Your feedback shapes the product. * Ship things. We do not have six month planning cycles. You will identify a problem, propose a solution, and execute, often in the same week. * Work with kind individuals. We are a small team of highly ambitious people with low egos. We want to have fun and enjoy working together. WHAT MAKES THIS DIFFERENT You are working at the forefront of potentially the biggest technological shift in history. Working at Langdock prepares you for the future of work. We went from €1 to €15M+ ARR in one year while being profitable. No aggressive sales tactics. No unsustainable burn. You will join early enough to shape how things work, but late enough that we have traction, customers, and a product people love. The hard part is not convincing people AI matters. It is helping them adopt it well. That is a genuinely interesting problem. 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 done something hard and can talk about it clearly, what worked, what did not, what you learned. * 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, what breaks, and why. * You are technical enough to understand how SaaS products work: databases, APIs, integrations, basic architecture. * You would rather own a problem than be told exactly what to do. * You are genuinely curious about how businesses work and why people buy things. * You are a kind person who cares about the people around you. 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.
