Principal ML Engineer required to join the founding team on the design and deployment of cutting-edge AI systems. This is a hands-on, high-intensity role - perfect for someone who thrives in fast-moving, high-stakes environments and wants to help build from the ground up.

Responsibilities

  • Build and deploy AI/ML systems that boost accuracy, speed, and user experience.
  • Partner with domain experts to turn complex workflows into AI-driven automation.

Requirements

  • Proven track record of delivering ML projects from idea → production with measurable impact.
  • Deep hands-on expertise with LLMs (fine-tuning, prompt engineering, evaluation, and deployment at scale).
  • Hands-on experience with PyTorch/TensorFlow, LangChain, vector databases, or similar tools.
  • Excellent communicator; comfortable working with non-technical stakeholders.
  • Thrive in chaos and love building zero-to-one.

This isn’t just another job - it’s a chance to be the Principal Engineer on a rapidly growing startup’s founding team. If you’re ready to go all in and build world-class AI, apply now for immediate review.
