Our business, and reputation, is growing fast and we’re always on the lookout for individuals who share our intellectual curiosity and desire to build a positive legacy through technology.

AI is an epoch-defining technology, join a company where you’ll be empowered to envision its most powerful applications, and to make them happen.

About the Team

Bringing medicine to patients is complex, expensive and high-risk. Faculty’s Life Science’s team is concentrated on building AI solutions which optimise the research and commercialisation of life-changing therapies.

We partner with major pharma firms, academic research centres and MedTech start-ups to design and deliver solutions which address critical healthcare challenges, and help to democratise health for all.

• Mentoring a small number of data scientists and supporting the professional growth of technical team members on projects.

• Partnering with commercial teams to build client relationships and shape project scope for technical feasibility.

• Contributing to Faculty’s thought leadership and reputation through delivering courses, public speaking, or open-source projects.

• Ensuring best practices are followed throughout the project lifecycle to guarantee high-quality, impactful delivery.

Who we're looking for:

• You possess senior experience in a professional data science position or a quantitative academic field.

• You demonstrate strong programming skills, with the ability to be a fluent Python programmer, using core libraries (NumPy, Pandas) and a deep-learning framework (e.g., PyTorch).

• You have a deep expertise in core data science paradigms (supervised/unsupervised, NLP, validation), demonstrating a proficiency across the standard data science toolkit, including the ability to develop new, innovative algorithms.

• You bring a leadership mindset, focused on growing the technical capabilities of the team and nurturing a collaborative culture.

• You exhibit commercial awareness, with experience in client-facing work and the ability to translate business problems into a rigorous mathematical framework.
