<p>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.</p>
<p>This is not a research role and not a prototype environment! You will work on a real, revenue-generating product used by <strong>millions of users</strong> and operating under extreme growth and real production pressure. Your technical decisions directly impact stability, performance, and user experience in live production.</p>
<h2>Tasks</h2>
<ul>
<li>Actively develop production-level code and take overall technical ownership.</li>
<li>Provide technical leadership to a small senior AI team (3–4 engineers).</li>
<li>Design the architecture for training, inference, and deployment of language models under high load and real-time requirements.</li>
<li>Improve context handling, memory mechanisms, retrieval approaches, and response quality.</li>
<li>Define and drive fine-tuning and post-training strategies.</li>
<li>Build precise moderation and classification solutions for adult / NSFW content, balancing safety with model quality and user freedom.</li>
</ul>
<h2>Requirements</h2>
<ul>
<li>7+ years of experience in software engineering and/or machine learning - company's <strong>main product LLM</strong>.</li>
<li>Proven responsibility for AI or LLM systems serving millions of users in production - at least <strong>30 million tokens per day</strong>.</li>
<li>Strong hands-on experience with Python, PyTorch, and modern LLM frameworks.</li>
<li>Practical experience with fine-tuning, data preparation, and model steering.</li>
<li>Comfortable working with <strong>adult / NSFW content</strong> within clearly defined technical and safety boundaries.</li>
<li>Able to collaborate reliably within European time zones (+/- 3 hours from European time zones) and having the right to work there.</li>
<li>Fluent in English.</li>
</ul>
<h2>Benefits</h2>
<ul>
<li>Fully remote role with long-term perspective.</li>
<li>Flexible contract models (B2B or EoR).</li>
<li>Salary up to <strong>$ 200,000 (depending on experience and setup)</strong></li>
<li><strong>Additional $ 80,000 in equity</strong> (company shares or stock options)</li>
<li>20 days of paid vacation and flexible working arrangements.</li>
<li>Budget for professional development, conferences, and learning resources.</li>
<li>Modern hardware and access to current AI tools.</li>
<li>High degree of autonomy and direct technical impact on a scalable product.</li>
</ul>
<p>You can expect a focused environment with short decision paths, high pace, and real technical ownership — not a corporate structure.</p>
<p>If you want to build LLM systems that operate under real production pressure and extreme growth, we look forward to your application.</p>
