EverAI is processing 80 million tokens per day and growing. We are looking for a Tech Lead to take the helm of our LLM team (currently 3 engineers) and own the architecture, training, and deployment of the models that power our core product. This is a role for a builder. You won't just be managing Jira tickets; you will be writing production code, defining our alignment strategy, and shipping features used by millions of users globally. We operate in the uncensored/NSFW space, which presents unique, high-complexity challenges in alignment, moderation, and steerability that you won't find in standard corporate AI.
Job Responsibility:
Ship Code & Lead from the Front: Act as a Player/Coach, Architect the system and mentor the team, spend significant time hands-on in the codebase (Python/PyTorch), Own the core chat loop: Optimize context windows, memory/RAG retrieval, and inference latency
Own the Model Lifecycle: Drive our strategy for SFT (Supervised Fine-Tuning) and RLHF/DPO (Preference Optimization), decide when to prompt, when to fine-tune, and when to architect a new RAG pipeline, Manage the 'Data Engine': oversee the sourcing, labeling, and cleaning of diverse datasets
Architect High-Precision Moderation: Build the immune system of the platform, design and train custom classifiers to detect and filter non-consensual or illegal content, Move beyond binary 'safe/unsafe' flags to create nuanced, context-aware moderation systems
Requirements:
8+ years of engineering experience
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
Understand the technical rigor required to moderate it effectively without breaking the user experience
Intuition for Alignment: understand the physics of LLMs—how prompt conditioning, temperature, and sampling affect the 'soul' of a chatbot
Doer Mindset: value velocity, can distinguish between a 'perfect' academic solution and a 'shippable' production solution
Owner: obsess over metrics, regressions, and the user experience long after the code has been merged
What we offer:
Paid Time Off: 4 weeks (20 working days) of PTO per year
Annual Gathering: A yearly in-person meetup
Health & Wellness Support: Up to $200 per year for wellbeing expenses + unlimited 1:1 sessions with psychologists and lifestyle experts through OpenUp (also available for up to three family members)
