  • Advanced technical skills: Strong Python and SQL proficiency for complex data querying and manipulation across large datasets
  • Cloud expertise: Experience with large-scale data processing and familiarity with cloud platforms (GCP, Azure, Databricks)

About this role

Quantium is seeking a Lead Data Scientist to drive analytical delivery and innovation within its healthcare division, based in the Johannesburg office. You would lead a technical team while partnering directly with major healthcare clients to develop data science and AI solutions that improve health outcomes and create business value. This combines hands-on technical work—designing complex analyses using Python, SQL, and cloud platforms—with team leadership, stakeholder management across all organizational levels, and the ability to translate sophisticated analytical insights into clear recommendations for non-technical audiences.

The role demands at least seven years in advanced analytics or data science, with one to two years of leadership experience, alongside a degree in mathematics, statistics, computer science, economics, or a related field. You'll need strong cloud expertise (GCP, Azure, or Databricks), consultative skills in building trusted client relationships, and a working understanding of generative AI applications. Healthcare sector experience is desirable but not essential; what matters more is your problem-solving approach, ability to think strategically, and capacity to mentor others while staying current with emerging technologies.

Beyond the technical and leadership demands, you'll work in a collaborative, multi-disciplinary environment with genuine flexibility—three days onsite, two remote, plus up to 30 days working from other Quantium locations annually. The role offers access to Quantium's Analytics Community for continuous learning and the chance to contribute to projects with meaningful impact across the health sector.
