What you will do

CORE RESPONSIBILITIES:

1. Model Customization & Tuning

• Select / fine-tune SOTA LLMs (Llama-3-70B, Mixtral-8×22B, Phi-3-mini, DeepSeek etc.) using LoRA / QLoRA + Flash-Attention.
• Build and curate a private dataset of explicit-but-policy-safe chat logs; reinforce with RLAIF on real user data.

2. Prompt & Persona Engineering

• Design multi-level prompt stacks (system → persona → scene → user) that ramp intimacy over time.
• Create auto-temperature systems to keep chats spicy yet sustainable.

3. Conversation Intelligence

• Architect long-term memory with vector DB + semantic tagging.
• Implement emotion / kink classifiers (RoBERTa or Tiny-Mistral) to steer replies dynamically.

4. Multimodal Integration

• Hook diffusion / TTS models for image, video, and audio replies.
• Optimize on-device inference (Core ML / NNAPI) for low-latency bursts.

5. Safety & Compliance

• Build tiered filters: soft in-prompt guardrails, hard regex / classifier gates.
• Iterate A/B tests to balance freedom and user safety.

6. Infra & Deployment

• Containerize with Docker; auto-scale on AWS / [Vast.ai](http://vast.ai/) spot GPUs.
• CI/CD pipeline for nightly retrains and canary releases to 5% of traffic.

7. Collaboration & Culture

• Pair daily with product, design, and mobile teams; prototype features in days, not quarters.
• Mentor juniors, share cursed anime memes in Slack, and keep the office vibe spicy.

What you will need

WHAT YOU BRING

• Proven track record fine-tuning LLMs (link to repo / model card).
• Fluency in Python + PyTorch; Rust or Go a plus.
• Deep familiarity with hentai, ero-manga, waifu tropes, and r/GoonsGoneWild culture.
• 3+ yrs shipping ML to prod, preferably at fast-moving start-ups.
• Ability to design content-safety systems without neutering the experience.

EXTRA CREDIT

• iOS / Android on-device ML optimisation.
• Diffusion or TTS model experience for adult content.

OTHER DETAILS:

PERKS

• Revenue-share tokens once Foxy passes 1 M MAU.
• Zero corporate HR cringe - just build stuff fast.

PROS & CONS

Massive impact: Your code shapes millions of horny chats.

Greenfield: Minimal legacy baggage.

Adult content: If you’re squeamish, bail.

High velocity: Comfort zones die here.
