• High agency with the ability to jump on any task as needed. 

• Hands on end-to-end development of high impact publications that use ML methodologies to solve biological problems. 

• Proven track record developing state-of-the-art ML models, ideally including transformers, diffusion models, or multimodal architectures.

• Experience applying ML to large multimodal biological datasets (genomics, transcriptomics, epigenomics, proteomics, single-cell data). 

• Exceptional coding skills (Python, PyTorch, JAX, TensorFlow) and familiarity with scalable training frameworks.

• Experience managing large-scale distributed training across GPUs/TPUs.

• Background in generative AI, large language models, mechanistic interpretability, or reinforcement learning.

Interview Process 

Our interview process is hard from the beginning, so please do come prepared to show us your strongest self. Marie is based in SF and Hannah in London - we are both available to support this process.

We promise to communicate clearly about our process, look for your strengths, be transparent in our feedback and listen to your feedback - we are always learning.

The interview steps are listed below. 1-3 are done remotely over video call. Our preference for 4-7 is in person, but remote is possible too. At stage 4 more information will be shared about the following steps.

1. Screen with Marie or Hannah

2. Meet Ravi

3. CV Deep Dive

4. Take Home Technical Challenge & Discussion

5. Analysis Challenge with Ravi

6. Systems Design & Live Coding

7. Presentation of your work to the wider team
