Job Description

🤖 Role Overview — GenAI Focus

This is a hybrid Data Scientist + Machine Learning Engineer position focused heavily on:

  • Large Language Models (LLMs)
  • Diffusion models (Stable Diffusion–type systems)
  • Synthetic data generation
  • End-to-end ML pipelines

It sits closer to Applied AI Engineer than traditional Data Scientist.

Location: Cupertino, California (USA)
Experience Required: 2+ years
Education: Bachelor’s in CS or related field

🧠 What You’ll Actually Do

1️⃣ Generative AI Development (Core Work)

You’ll:

  • Fine-tune LLMs
  • Build diffusion-based models
  • Optimize GenAI architectures
  • Apply models to real business use cases

This is cutting-edge AI work.

2️⃣ Synthetic Data Pipelines

One of the most valuable parts:

  • Design pipelines using LLMs to generate synthetic datasets
  • Improve training data quality
  • Automate dataset creation

Synthetic data is a high-growth AI domain right now.

3️⃣ ML Engineering & Deployment

Responsibilities include:

  • Model deployment
  • Scalable training pipelines
  • Distributed computing workflows
  • Automation tooling

So this is not just research — it’s production engineering.

4️⃣ Cross-Functional Collaboration

You’ll work with:

  • Research teams
  • Data engineers
  • Product teams
  • Program managers

This means strong communication is required.

🔧 Required Technical Skills

Must-Have

  • Python (expert level)
  • PyTorch (or similar deep learning frameworks)
  • Machine learning fundamentals
  • Data preprocessing & evaluation
  • LLM experience
  • Diffusion model experience

This already places the role at mid-level AI engineer.

Bonus Skills (Implied)

Even if not listed, success often requires:

  • GPU training optimization
  • Hugging Face ecosystem
  • Distributed training (DDP, DeepSpeed)
  • Cloud ML platforms
  • Vector databases
  • Prompt engineering

📊 Seniority Level — Important

Despite only “2+ years” mentioned, the skill depth suggests:

👉 Mid-level ML Engineer / Applied Scientist

Not entry level.

Companies often underestimate experience requirements in GenAI postings.

💰 Salary Expectation (Typical Market)

For Cupertino / Silicon Valley:

Estimated range:

  • $130k — $180k base
  • Higher if contract through major client
  • Could exceed $200k with bonuses/equity (depending on end client)

🚀 Career Value

This role is extremely valuable for future growth:

After 2–3 years you could move to:

  • Senior ML Engineer
  • Applied Scientist
  • GenAI Engineer
  • AI Research Engineer
  • Staff AI Engineer

GenAI experience is currently among the highest-paid tech skills globally.

⭐ Strengths of This Role

✅ Cutting-edge AI domain
✅ LLM + diffusion exposure
✅ Synthetic data expertise
✅ Production ML experience
✅ Silicon Valley ecosystem
✅ High career leverage

⚠️ Challenges

❗ Fast-paced environment
❗ High technical expectations
❗ Requires strong math + engineering
❗ Likely heavy experimentation cycles
❗ Work authorization required (USA)
