Lead Conversational Ai Platform Engineer (M/W/D)

As a specialized recruiting firm, we are hiring on behalf of our client an experienced Tech Lead who will own the technical core of a globally used AI platform. This is not a research role and not a prototype environment! You will work on a real, revenue-generating product used by millions of users and operating under extreme growth and real production pressure. Your technical decisions directly impact stability, performance, and user experience in live production. Tasks • Actively develop production-level code and take overall technical ownership. • Provide technical leadership to a small senior AI team (3–4 engineers). • Design the architecture for training, inference, and deployment of language models under high load and real-time requirements. • Improve context handling, memory mechanisms, retrieval approaches, and response quality. • Define and drive fine-tuning and post-training strategies. • Build precise moderation and classification solutions for adult / NSFW content, balancing safety with model quality and user freedom. Requirements • 8+ years of experience in software engineering and/or machine learning. • Proven responsibility for AI or LLM systems serving millions of users in production. • Strong hands-on experience with Python, PyTorch, and modern LLM frameworks. • Practical experience with fine-tuning, data preparation, and model steering. • Comfortable working with adult / NSFW content within clearly defined technical and safety boundaries. • Based in Europe and able to collaborate reliably within European time zones. Benefits • Fully remote role with long-term perspective. • Flexible contract models (B2B or EoR). • Salary up to € 200,000 (depending on experience and setup) • Additional $ 80,000 in equity (company shares or stock options) • 20 days of paid vacation and flexible working arrangements. • Budget for professional development, conferences, and learning resources. • Modern hardware and access to current AI tools. • High degree of autonomy and direct technical impact on a scalable product. You can expect a focused environment with short decision paths, high pace, and real technical ownership — not a corporate structure. If you want to build LLM systems that operate under real production pressure and extreme growth, we look forward to your application.
