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. EverAI is processing 80 million tokens per day and growing. 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, 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
Own the Model Lifecycle
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
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 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 and 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
Understand the physics of LLMs—how prompt conditioning, temperature, and sampling affect the 'soul' of a chatbot
Value velocity
can distinguish between a 'perfect' academic solution and a 'shippable' production solution
Obsess over metrics, regressions, and the user experience long after the code has been merged
What we offer:
Fully remote
4 weeks (20 working days) of PTO per year
Annual in-person meetup
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)
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
Company laptop provided + monitor budget up to $250 for your workspace setup
AI Tools Access: Premium access to ChatGPT, Cursor, Hugging Face, and others
