📋 Description

• Act as a Player/Coach: Architect the system and mentor the team, but spend significant time hands-on in the codebase (Python/PyTorch) • Own the core chat loop: Optimize context windows, memory/RAG retrieval, and inference latency to ensure a seamless, real-time experience • Drive our strategy for SFT (Supervised Fine-Tuning) and RLHF/DPO (Preference Optimization) • Manage the "Data Engine": oversee the sourcing, labeling, and cleaning of diverse datasets to improve model steerability and multicultural performance • Build the immune system of the platform. You will design and train custom classifiers to detect and filter non-consensual or illegal content within an explicit environment • Move beyond binary "safe/unsafe" flags to create nuanced, context-aware moderation systems.

🎯 Requirements

• 8+ years of engineering experience, with a significant portion dedicated to shipping ML/LLM features to millions of active users • Proficient in Python/PyTorch • Comfortable with the modern LLM stack (vLLM, HuggingFace, fine-tuning pipelines, eval frameworks) • Comfortable working with NSFW content and understand the technical rigor required to moderate it effectively without breaking the user experience • Intuition for Alignment: You understand the physics of LLMs—how prompt conditioning, temperature, and sampling affect the "soul" of a chatbot • Doer Mindset: You value velocity. You can distinguish between a "perfect" academic solution and a "shippable" production solution. • Owner: You don't rent code. You obsess over metrics, regressions, and the user experience long after the code has been merged.

🏖️ Benefits

• Paid Time Off: 4 weeks (20 working days) of PTO per year to recharge and reset • Health & Wellness Support: Up to $200 per year for wellbeing expenses + unlimited 1:1 sessions with psychologists and lifestyle experts • Co-Working Space Budget: Work from a co-working space up to twice per month (35 EUR / 40 USD per visit) • Learning Budget: Dedicated funds to support your professional growth: courses, books, conferences, events, or certifications • Equipment: Company laptop provided + monitor budget up to $250 for your workspace setup • AI Tools Access: Premium access to ChatGPT, Cursor, Hugging Face, and others to power your ideas and workflows
