At EverAI, we’re shaping what it means to connect with AI. With 40 million users and counting, we're not just building products — we're creating entirely new categories. Our flagship product is the world’s largest AI girlfriend/boyfriend platform, redefining relationships for millions. It is governed by our proprietary moderation system, EverGuard — an internal AI designed to ensure everything we build is safe, ethical, and human-first. 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.
Job Responsibility:
Ship Code & Lead from the Front: 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
Own the Model Lifecycle: Drive strategy for SFT and RLHF/DPO
Manage the Data Engine: oversee the sourcing, labeling, and cleaning of diverse datasets
Architect High-Precision Moderation: design and train custom classifiers to detect and filter non-consensual or illegal content
Requirements:
8+ years of engineering experience with a significant portion dedicated to shipping ML/LLM features to millions of active users
Deeply technical and proficient in Python/PyTorch
Comfortable with the modern LLM stack (vLLM, HuggingFace, fine-tuning pipelines, eval frameworks)
Comfortable working with NSFW content and understanding the technical rigor required to moderate it effectively
Intuition for Alignment: understanding the physics of LLMs
Doer Mindset: values velocity and can distinguish between a perfect academic solution and a shippable production solution
Owner: obsesses over metrics, regressions, and the user experience
