Test Architect/ Test Lead

ML Engineer — Test & Learn Platform (3+ Years Experience)

About the Role

We're looking for an ML Engineer to join our Test & Learn Platform team. You'll build

and scale our experimentation and causal inference services — from statistical engines

to API integrations and cloud pipelines — empowering business teams globally to make

data-driven decisions.

What You'll Do

 Develop and maintain statistical/ML modules (DID, Synthetic Control, A/B

Testing, Multi-Treatment Effects) in Python

 Build and extend FastAPI services and integrate them with our web application

via SDK wrappers

 Design and optimize large-scale data pipelines using PySpark, Delta Lake, and

Azure Data Lake

 Profile and resolve OOM issues in PySpark jobs — optimize memory allocation,

partitioning, broadcast joins, caching strategies, and Spark configurations

 Deploy and manage workloads on Databricks, including job clusters, notebooks,

and Delta Lake tables

 Containerize and deploy services using Docker, Kubernetes, and CI/CD pipelines

 Ensure code quality and security via SonarCloud, Snyk, and pytest

 Collaborate with data scientists and product teams to translate research into

production-ready modules

Must-Have Skills

 Python (3.9+) — 3+ years of production experience

 PySpark & Spark Internals — strong experience with Spark memory model,

executor tuning, shuffle optimization, and diagnosing/resolving OOM errors

(broadcast thresholds, partition skew, spill-to-disk, GC tuning)

 Databricks — hands-on with job orchestration, cluster configuration, notebook

workflows, and Delta Lake optimization (Z-ordering, compaction, caching)

 Causal Inference & Experimentation — DID, synthetic control, A/B testing,

hypothesis testing, panel data methods

 Statistics/ML Libraries — statsmodels, scikit-learn, scipy, pandas, numpy

 API Development — building RESTful services with FastAPI (or similar)

 Cloud (Azure) — Azure Storage, Azure ML, Data Lake

 Docker & Kubernetes — containerization and orchestration for ML workloads

 Testing — writing robust unit/integration tests with pytest

Nice-to-Have

 Experience with Celery/Redis for async task orchestration

 Familiarity with Polars, PyArrow, or SQLAlchemy

 Background in econometrics or experimental design

 Spark UI profiling and performance benchmarking

 CI/CD tooling (SonarCloud, Snyk, GitHub Actions)

What Sets You Apart

 You can look at a Spark execution plan and pinpoint why a job is OOM-ing

 You think in modules — clean separation of data processing, inference, and post-

processing

 You can go from a Jupyter notebook prototype to a production-grade, testable

service

 You're comfortable with both statistical rigor and software engineering best

practices
