  • Lead and code: Architect systems, mentor engineers, and stay hands-on in Python/PyTorch.
  • Own the model lifecycle: From fine-tuning and RLHF/DPO to designing RAG pipelines.
  • Build smarter moderation: Develop classifiers and safety systems that go beyond simple filters.

What We’re Looking For

  • Proven experience shipping AI/LLM products at scale.
  • Deep technical skills in Python, PyTorch, and modern LLM stacks.
  • A builder’s mindset: fast, pragmatic, and obsessed with quality.
  • Ownership mentality: you care about performance, reliability, and user experience.

Tech Environment

  • Scale: 80M+ tokens/day.
  • Team: Small, high-impact group with direct access to leadership.
  • Culture: High autonomy, low bureaucracy, big challenges.
