What you will do
- Design and document data architecture for enterprise clients, covering medallion patterns, domain driven design and governance frameworks.
- Build and orchestrate ingestion and transformation pipelines, with a bias towards metadata driven approaches that scale beyond a single project.
- Lead migration and modernisation work, moving workloads from platforms such as Teradata and on premises SQL Server into Fabric and Azure.
- Deliver end to end Fabric implementations across Lakehouse, Warehouse, Data Factory, OneLake and Real Time Intelligence.
- Build and tune Power BI semantic models, including DAX, row level and object level security, and deployment pipelines.
- Establish CI/CD for data platforms, including source control, branching strategy, automated deployment and environment promotion.
- Apply AI native engineering practices to accelerate delivery, including agentic workflows and the Model Context Protocol.
- Set technical standards and review the work of other engineers. At Lead level, this includes owning the technical direction of an engagement and mentoring the delivery team.
Core Skills
- Microsoft Fabric, end to end Lakehouse, Warehouse, Data Factory, OneLake and Real Time Intelligence.
- Power BI Semantic models, DAX, row level security and object level security, deployment pipelines, and performance tuning.
- Data architecture Medallion patterns, domain driven design, and governance frameworks.

- Open-minded collaborator, always seeking the best solution, not holding onto dogmatic approaches.
- Favours teamwork and collaboration over individual delivery.
- Self-motivated and expects the same from others on their team.
- Spots learning opportunities and actively shares their knowledge.
- Recognizes when team members are in a comfort zone and look for ways to challenge more junior team members.

Nice to have
- Experience designing and delivering training, whether formal client enablement sessions, internal upskilling, or structured handover to a client team at the end of an engagement. This carries real weight for us, because a large part of the value we leave behind is a client team that can operate the platform without us.
- Relevant Microsoft certifications in the Fabric, Azure data or Power BI tracks.
- Experience in a consulting or client facing delivery environment.
- Exposure to data governance tooling such as Microsoft Purview.
What we look for beyond the technology
- Clear written communication. Much of the role is remote, and decisions need to survive being read rather than explained in person.
- Comfort with ambiguity at the start of an engagement, and the discipline to reduce it quickly.
- A willingness to be challenged on architectural decisions, and to challenge others in turn.
Location and ways of working
The role is fully remote. Candidates based in Cape Town are favoured, because the role involves occasional in person meetings with colleagues and clients. Applicants outside Cape Town will be considered where the rest of the profile is a strong match, and should be willing to travel for those sessions on occasion.
Remuneration
The range spans the Senior and Lead levels. Placement within it depends on demonstrated experience, depth of hands on
Fabric delivery, and the degree of architectural and client ownership the appointee takes on
