Job Description
As part of our ML team, you will design, build, and deploy models that directly impact merchant-facing intelligence. This includes forecasting, anomaly detection, segmentation, automation, and product-layer ML.
You’ll work with high ownership, building practical systems that matter in real-world payments, a context most ML engineers rarely experience.
What You’ll Work On
-
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).
-
Build automation tooling alongside ML pipelines (Airflow DAGs, pipeline scaffolding).
-
Contribute to product and strategic decision-making.
Our Tech Stack
-
Apache Spark & Airflow
-
Google Vertex AI

Python

Requirements
-
3+ years as an ML engineer in production environments.
-
Strong Python skills and comfort with Spark for large-scale data processing.
-

-
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

Clear reasoning behind design decisions.
-
Systems that are maintainable and understandable.
-
Honesty about model limitations in production.
-
Closing the loop between model outputs and business outcomes.
