About Valence Labs

Valence Labs is an AI research and productization engine within Recursion dedicated to industrializing scientific discovery to radically improve lives. Combining the intellectual freedom of academia with the resources and stability of industry, our focus is the development of highly-autonomous systems that will spearhead a fundamental shift in the way treatments are discovered and developed for complex disease. Our research is driven by optimism, purpose, and a shared vision for a healthier tomorrow. We publish in top journals and conferences, are deeply committed to open-science and open-source, and maintain some of the largest and most active research communities in our industry. Our team is located in London and Montreal, where we share close connections with Mila, the world’s largest deep learning research institute.

About the role

We’re seeking an experienced Machine Learning Engineer to contribute to development of software and specifically LLM-based systems that will help in our mission of industrializing scientific discovery to radically improve lives. We're looking for individuals with strong engineering skills, including expertise in designing, implementing, improving, and deploying large language modeling systems at significant scale. In addition, we value proficiency with state-of-the-art machine learning algorithms and exceptional problem-solving skills. In this role, you will:

  • Support Valence Labs’ research agenda for the application of LLM-based applications in drug discovery.
  • Engage with and contribute to open-source libraries developed by Valence and the research community.
  • Create and improve novel ML methods applicable to LLM systems that will accelerate drug discovery.
  • Collaborate with an interdisciplinary team of dry and wet lab scientists to inform and improve our models and systems.
  • Fine-tune existing open source LLMs and potentially develop proprietary models for specialized tasks.
  • Design and implement a Retrieval-Augmented Generation (RAG) system leveraging vector database technology to enhance the model's capability for generating contextually relevant and accurate responses by efficiently retrieving and incorporating external data.
  • Enhance system capabilities by researching advanced reasoning frameworks for orchestrating complex workflows, incorporating multi-option decision-making, self-reflection, and external memory integration to improve planning, evaluation, and knowledge retrieval.

A successful candidate will have most of the following:

  • PhD or Master's degree with 3+ years of industry experience.
  • Strong programming skills and understanding of modern software development practices, especially in Python.
  • LLM application development experience, ideally with LangChain, and experience building RAG systems/Prompt Engineering or eagerness to learn is highly desirable.
  • Proven track record in machine learning, including building LLM-based systems (ideally with LangChain library), designing new architectures, hands-on experimentation, analysis, visualization, and model deployment in production systems.
  • Demonstrated capability to understand and summarize scientific content and implement deep learning models and novel LLM methods based on descriptions from publications.
  • Strong knowledge of linear algebra, calculus, and statistics.
  • Passion for applying ML research to real-world problems.

Nice to have:

  • Experience in building and deploying high-performance implementations of NLP deep learning algorithms.
  • Scientific knowledge of biology, chemistry, or physics along with previous experience working in a scientific environment across disciplines.
  • Contribution to high-visibility ML codebases.

Valence Labs is committed to creating a diverse and inclusive environment, where understanding and accommodating personal needs and preferences is a priority. Join our multidisciplinary team of passionate researchers, eager to push the boundaries of ML research and contribute to industrializing scientific discovery to radically improve lives.
