Senior Machine Learning Engineer

In a world of immense uncertainty, digiLab is a pioneering AI company that empowers governments and organisations in safety‑critical or highly regulated industries to solve critical, complex, and high‑stakes challenges using machine learning and uncertainty quantification.

From forging a path to clean energy to life‑saving medical diagnostics and beyond, making critical decisions with unwavering confidence is difficult, especially when data is complex, sparse, or incomplete. This is where digiLab’s expertise shines through.

Our trustworthy and explainable AI platform, The Uncertainty Engine, supported by our team of machine learning specialists and data scientists, enables decision‑makers to accelerate innovation, reduce the risk of failure, turn insight into action, and deliver greater value through more informed and confident decisions.

Senior Machine Learning Engineers play a key role in driving the technical aspects of our AI initiatives, leading the development of machine learning models, and guiding the delivery of solutions for client benefit.
