Description
Epoch Biodesign
Epoch Biodesign is a well-funded, venture-backed start-up using biology to make every type of plastic recyclable - starting with nylon.
Using a unique combination of AI, synthetic biology and green chemistry, we are scaling enzymatic recycling in order to transform currently unrecyclable plastics and textiles into new, virgin-quality materials. Our technology yields substantial reductions in carbon emissions with disruptive unit economics, preventing waste from entering landfill or the environment, allowing us to solve this very urgent challenge.
With our pilot plant already processing nylon 6,6 waste, we will imminently complete construction on our larger demo facility. This site will produce material destined for use in garments made by some of the world’s biggest fashion, sportswear and luxury brands, and also in components for some of the world’s largest car companies.
The Role
As a Machine Learning Engineer at Epoch you will design and build custom machine learning models that deepen our understanding of protein sequence–structure–function relationships, directly informing enzyme engineering decisions. Working closely with computational and lab biologists, you will rapidly prototype approaches, figure out what works and what doesn't, and develop custom models - not off-the-shelf solutions - grounded in evolutionary constraints. We want someone scrappy and pragmatic who can move fast, test ideas cheaply, and pivot without hesitation.
Your Core Activities Will Include

Your Core Activities Will Include
- Building custom machine learning and probabilistic models to capture meaningful patterns in protein sequence and structure data, with an emphasis on understanding evolutionary and functional relationships
- Developing hierarchical and Bayesian modelling approaches to integrate heterogeneous experimental data (e.g. high-throughput screening results alongside detailed biochemical assays)
- A degree (PhD preferred) in a quantitative or life-science field such as computational biology, bioinformatics, mathematics, computer science, physics, biochemistry or similar — with demonstrated application to biological problems
- Hands-on experience applying machine learning in a life-science or biotechnology context
- Demonstrated ability to build custom models from scratch, not solely relying on pre-trained or foundation models - including experience with probabilistic and/or Bayesian modelling approaches
- Strong technical background in Python and common scientific/ML libraries (e.g. NumPy, SciPy, Pandas, scikit-learn, PyTorch or equivalent)
- Experience working with protein sequence and/or structure data
- Experience with environment and dependency management tools (e.g. Conda, Mamba)
- Skills in data engineering, cleaning and preprocessing of experimental datasets
- Skills in data visualisation (e.g. Matplotlib, Plotly or equivalent)
- Excellent interpersonal skills, with demonstrable evidence of working collaboratively in an interdisciplinary environment
- Experience with version control systems (Git)
- Experience with deep learning methods applied to biological data
