Our Vision & Products
🚀 EverAI — Building the Future of AI Companionship
One of the Top 15 Largest & Fastest-Growing AI Companies in the World
50 Million Users in 2 years — Help Us Reach 100M first, 500M next
At EverAI , we’re shaping what it means to connect with AI. With 50 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 companionship 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 .
And we’re only just getting started!
Our Team
We are an enthusiastic, passionate and hardworking team of ≈ 75 people. Our founding team has strong entrepreneurial experience building and scaling web products from 0 to IPO.
The Opportunity
We aren't building a wrapper; we are building a massive-scale conversational intelligence. EverAI has created a platform dedicated to personalized human connection, enabling millions of users to create and interact with highly personalized AI companions.
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.
Co budeš dělat
- 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) . You 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 to improve model steerability and multicultural performance.
- Architect High-Precision Moderation
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.
