The ideal candidate has a machine learning background with biotech industry experience building generative ML models, pre-processing pipelines, and comprehensive benchmarks to support biological sequence design.

Candidates should have experience and interest in:

• Designing, training and fine-tuning deep learning models to engineer proteins, RNA or DNA.
• Implementing rigorous testing, documentation, and model benchmarking.
• Incorporating these models into AI-enabled toolchains for the biology lab.
• Collaborating with cross-functional teams to translate ML model predictions into evaluated sequences by the wet lab.

Qualifications:

• PhD in applied mathematics, computer science, physics, computational biology or other quantitative disciplines.
• Proven track record in developing deep learning models.
• Experience with large language models (e.g. autoregressive LLMs) for biological sequences.
• Expertise in at least one ML framework (PyTorch/TensorFlow/Jax) and robust experience in the Python data science ecosystem.
• Experience in training and deploying ML models on distributed computing services

Working at FL97, you would have access to advanced technology in the areas of:
