EverAI is hiring a Tech Lead, LLM & Generative AI. In this full remote role based in Slovakia, you will own the architecture, training, and deployment of models that power a large-scale conversational AI platform. This is a hands-on, player/coach position where you will lead the LLM team while shipping production code that reaches millions of users daily.
What You'll Do
- Lead from the front by shipping code, architecting systems, and mentoring the team while spending significant time hands-on in the Python/PyTorch codebase.
- Own the core chat loop: optimize context windows, memory/RAG retrieval, and inference latency for a seamless, real-time user experience.
- Drive the model lifecycle strategy, deciding when to prompt, fine-tune, or architect new RAG pipelines, including SFT and RLHF/DPO.
- Manage the 'Data Engine', overseeing sourcing, labeling, and cleaning diverse datasets to improve model steerability and multicultural performance.
- Design and train custom classifiers for high-precision moderation to detect non-consensual or illegal content within an explicit environment.
- Build nuanced, context-aware moderation systems that move beyond simple safe/unsafe binary flags.
What We're Looking For
- 8+ years of engineering experience, with a significant portion dedicated to shipping ML/LLM features to millions of active users.
- Deep proficiency in Python/PyTorch and familiarity with the modern LLM stack (vLLM, HuggingFace, fine-tuning pipelines, evaluation frameworks).
- Comfort working with NSFW content and understanding the technical rigor required to moderate it effectively without harming the user experience.
- Strong intuition for alignment: understanding how prompt conditioning, temperature, and sampling affect LLM outputs.
- A doer mindset that values velocity and can distinguish between academically perfect and shippable production solutions.
- An owner mentality that obsesses over metrics, regressions, and user experience long after code is merged.
Technical Stack
- Python
- PyTorch
- vLLM
- HuggingFace
Team & Environment
You will lead the LLM team, which currently consists of 3 AI Engineers reporting to you. You'll also collaborate with DevOps and Web teams, and you will report directly to the CTO.
Benefits & Compensation
- 4 weeks (20 working days) of PTO per year.
- Annual in-person team meetup.
- Up to $200 per year for wellbeing expenses.
- Unlimited 1:1 sessions with psychologists and lifestyle experts through OpenUp (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 for professional growth (courses, books, conferences, events, or certifications).
- Company laptop provided plus a monitor budget up to $250.
- Premium access to AI tools: ChatGPT, Cursor, Hugging Face, and others.
