Data Scientist

Portal Biotech

About the role

We’re looking for a Data Scientist to develop cutting-edge algorithms that unlock insights from complex, noisy time-series data. You’ll work directly with data from our core nanopore technologies, creating methods using techniques from deep learning, probabilistic modelling, and dynamic programming. Collaborating closely with our scientists and engineers, you’ll turn experimental data into actionable outputs and scalable tools. This is a unique opportunity to bring state-of-the-art ML techniques into real-world proteomics—and shape the future of biomedical discovery.

Tasks and responsibilities

  • Research, design, and implement algorithms for analysing time-series data from our core technologies
  • Collaborate with data scientists and engineers to integrate models into pipelines and tools.
  • Document methods and support reproducibility, validation, and publication where appropriate.
  • Stay current with academic and industry advances in temporal modelling and deep learning.

Qualifications

  • Strong programming and modelling skills in Python (NumPy, PyTorch or TensorFlow, SciPy, pandas).
  • In-depth knowledge of machine learning for time-series, including RNNs, LSTMs, GRUs, transformers, attention mechanisms.
  • Solid understanding of probabilistic models (HMMs, Bayesian inference, graphical models).
  • Experience designing or adapting dynamic programming algorithms.
  • A graduate degree (PhD or MSc) in numerate discipline, e.g. Computer Science, Data Science, Mathematics, Physics, or Bioinformatics.
  • Ability to work in a research-style setting and translate ideas into production- ready code.

Desirable

  • Experience working with biological or biomedical time-series data, or other noisy data (e.g., electrophysiology, proteomics, sensor data).
  • Familiarity with domain-specific data types (e.g. DNA/RNA sequences, microscopy, nanopore sensing).
  • Publications or open-source contributions in relevant areas.
  • Experience optimising scientific computing code (e.g., JAX, CUDA, Cython).
  • Exposure to model interpretability and regulatory considerations in biotech/healthcare.
