AI Systems Builder (Impact-Driven) [33162]

Stealth Startup
Menlo Park, CA

We’re hiring an Applied AI Engineer to design, fine-tune, and deploy production-grade AI models powering next-generation AI agents in financial workflows.


This role sits at the intersection of research and real-world deployment — taking models from experimentation to high-stakes production systems.


What You’ll Do


Model Development

  • Fine-tune LLMs and multimodal models for domain-specific use cases
  • Design post-training workflows (instruction tuning, RLHF, evaluation loops)
  • Optimize training pipelines using open-source frameworks
  • Run ablation studies and hyperparameter tuning


AI Agent Systems

  • Build AI agents capable of executing multi-step workflows
  • Integrate models into production environments
  • Improve robustness, accuracy, and reliability
  • Develop evaluation frameworks for edge cases


Data & Collaboration

  • Work with proprietary datasets
  • Build labeling and data-quality pipelines
  • Partner with product and engineering teams globally


Requirements

  • 1–4 years hands-on ML/AI training experience
  • Strong Python + PyTorch
  • Experience with Hugging Face ecosystem
  • Experience deploying models to production
  • Understanding of model evaluation trade-offs


Bonus: RLHF, model distillation, RAG, distributed training, GPU optimization, multi-agent systems.
