• Design and ship per-merchant payment volume forecasting systems (time-series decomposition, Africa-specific event calendars, quantile regression).

• Build and maintain fraud/anomaly detection across the payment stack with tiered alerting logic.

• Own dynamic merchant segmentation systems (rule-based + data-driven hybrid).

• Instrument and monitor deployed models (drift detection, retraining triggers, evaluation pipelines via Vertex AI).

• Contribute to product and strategic decision-making.

• Solid grasp of the ML lifecycle.

• Ability to design for batch infrastructure.

• High ownership mentality and proactive problem-solving.

• Ability to identify gaps in data-driven business processes.

Strong Plus:

• Familiarity with Vertex AI (custom training jobs, pipelines, monitoring).

• Experience in payments, fintech, or domains with real-world operational constraints.

• Exposure to African market dynamics.

• Experience with automation/workflow tooling (e.g., n8n).

What We Value in ML Engineers
