The Opportunity We’re building a massive-scale conversational intelligence platform dedicated to personalized human connection, enabling millions of users to create and interact with highly personalized AI companions. EverAI processes 80 million tokens per day and is 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.
Why this role is distinct
Massive Scale: Solve latency, throughput, and context management challenges at a scale of 80 M+ daily tokens.
Production Focus: This is not a research sandbox. If you fine‑tune a model today, it impacts millions of users tomorrow.
Nuanced Engineering: Because we are "uncensored," we cannot rely on lazy, blanket safety filters. Build sophisticated classifiers and alignment strategies to balance user freedom with strict safety guardrails.
What You Will Do
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). Decide when to prompt, fine‑tune, or architect a new RAG pipeline.
Manage the "Data Engine": oversee 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.
Who You Are
You have shipped AI at scale. 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).
You understand the "Uncensored" challenge and can work with NSFW content while maintaining rigorous moderation without breaking UX.
Intuition for Alignment: Understand the physics of LLMs – how prompt conditioning, temperature, and sampling affect the "soul" of a chatbot.
Doer Mindset: Value velocity, distinguishing 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.
The Tech Stack & Environment
Scale: 80 M+ Daily Tokens.
Team: You + 3 AI Engineers (reporting to you) + DevOps/Web collaborations.
Culture: High autonomy, low bureaucracy, direct line to the CTO.
Are you ready to build the engine for millions of users? Let’s talk.
Why EverAI?
Exponential Growth: From 40M users in 2 years, to 100M next — and 500M beyond.
Track Record of Category‑Creating Innovation: Consistently launch world‑first AI applications.
Global Impact: Top‑tier user growth, real‑world adoption, and cultural relevance.
Proven Leadership: Senior team launched, scaled, and exited/IPO’d multiple scale‑ups.
Elite Remote Team: 100% remote; world‑class talent from Tier 1 tech companies, culture of ownership, velocity, and radical creativity.
️ Ethical Core: AI ecosystem governed by EverGuard, our proprietary AI moderation technology.
What We Offer
✍️ Contract Type: Prefer B2B, but flexible; long‑term commitment and impact.
Work From Anywhere: Fully remote. Choose the environment where you do your best work.
️ Paid Time Off: 4 weeks (20 working days) of PTO per year.
Annual Gathering: Yearly in‑person meetup.
❤️ Health & Wellness Support: Up to $200 per year for wellbeing expenses + unlimited 1:1 sessions with psychologists and lifestyle experts (OpenUp), up to three family members.
Co‑Working Space Budget: Up to twice per month (35 EUR / 40 USD per visit).
Learning Budget: Dedicated funds for courses, books, conferences, events, certifications.
Equipment: Company laptop + monitor budget up to $250.
⚡ AI Tools Access: Premium access to ChatGPT, Cursor, Hugging Face, and others.
