  • Familiarity with deep learning frameworks (e.g., PyTorch, JAX, TensorFlow).
  • Experience in ML research beyond completing a PhD (e.g., supervision, industry experience, leading academic initiatives).
  • Excellent communication skills for reporting and presenting research findings.
  • Curious and innovative disposition capable of devising novel, well‑founded algorithmic solutions.
  • Good social skills and ability to motivate, inspire, and mentor team members.
  • Comfortable working in fast‑paced, agile environments, managing uncertainty and ambiguity.

Preferred Qualifications

  • High‑impact publications in top‑tier conferences or other influence in the research community.
  • 5+ years of hands‑on experience leading teams building advanced ML/NLP/IR systems in academia or commercial applications.
  • Extensive experience with deep learning and large‑scale model training.
  • Extensive experience working on agent‑based systems, tool‑using AI, or multi‑agent coordination in LLM contexts.
  • Strong software and/or infrastructure engineering skills, with code contributions to open‑source libraries or production code.
  • Experience training large‑scale models over distributed nodes with cloud tools such as Amazon AWS, MS Azure, or Google Cloud.

Benefits

  • Learning and development opportunities through on‑the‑job coaching and cutting‑edge methods.
  • Access to large datasets, compute, and high‑impact problems.
  • Competitive compensation & benefits packages.
  • Hybrid work model with flexible remote options.
  • Work‑life balance initiatives, including flexible work arrangements and paid volunteer days.
