We're looking for experienced machine learning researchers with hands-on experience training and improving deep learning models end-to-end, across vision and language.

You'll work on well-scoped empirical open-ended ML research problems.

Responsibilities

  • Train image classifiers and generative image models from scratch, and fine-tune open-weight language models.
  • Get the most out of limited data, compute, and model-size budgets.
  • Make models robust — to adversarial inputs and to adversarial conversations.
  • Compress models to meet hard size and latency constraints without sacrificing accuracy.
  • Diagnose and resolve training issues.

Requirements

  • We are looking for candidates with strong expertise in one or more of the following areas:
  • Adversarial Robustness

Experience with

  • Adversarial training of image classifiers (e. g. PGD-based training, TRADES).
  • Evaluating robust accuracy under standard threat models (e. g. L∞ attacks, Auto Attack) and avoiding gradient-masking pitfalls.
  • Managing the robustness–accuracy trade-off and robust overfitting.
  • Efficient Computer Vision

Experience with

  • Training image classifiers end-to-end, especially for fine-grained recognition (many visually similar classes, few examples per class).
  • Model compression: quantization, pruning, and knowledge distillation from large teachers into small students.
  • Deploying models under hard size or latency budgets (on-device, edge, or embedded settings).
  • Generative Image Modeling

Experience with

  • Training image generative models from scratch: diffusion models, GANs, VAEs, or flow-based models.
  • Iterating against sample-quality metrics such as FID.
  • Training-efficiency tricks that produce good generators quickly and at small parameter counts.
  • LLM Post-Training & Behavioral Robustness

Hands-on experience with one or more of

  • Supervised fine-tuning and preference optimisation (DPO, RLHF, RLAIF) of open-weight language models, including building your own datasets via synthetic generation, noisy or weak supervision, and rejection sampling.
  • Shaping conversational behaviour over multiple turns: resistance to persuasion and sycophancy, calibrated confidence, and knowing when to accept corrections.
  • Alignment-style fine-tuning that changes a specific behaviour while preserving general capability.
  • Multilingual Pre-training

Experience with

  • Training multilingual or low-resource-language models from scratch.
  • Tokenizer design across scripts and typologically diverse languages.
  • Balancing highly unequal per-language data (sampling temperatures, cross-lingual transfer) in data-constrained regimes.
  • Additional Areas of Interest

Experience in any of the following is a plus

  • Scaling laws and training-efficiency research.
  • Curriculum learning and data ordering.
  • Model evaluation: benchmark construction, contamination control, statistically sound comparisons.
  • Uncertainty estimation and model calibration.
  • Data augmentation and synthetic data for robustness.
  • General Qualifications
  • 3+ years of machine learning research experience (Ph D research counts toward this requirement).
  • Strong experience with Py Torch, JAX, Tensor Flow, or similar ML frameworks.
  • Degree from a top-100 university, experience at a FAANG or comparable AI company, or an equivalent research track record through publications or impactful open-source contributions.
  • Why Join
  • Work on cutting-edge machine learning research.
  • Collaborate with leading AI researchers on challenging, high-impact projects.
  • Flexible, project-based work with competitive compensation.
