• Familiar with or have worked with these technologies (or alternatives):
• Data Processing & Streaming: Apache Spark, DBT, Airflow, Airbyte, Kafka
• Data Storage: Data Lakehouse architectures, Apache Iceberg, Vector Databases, RDS
• Backend & APIs: FastAPI, micro-service architecture
• Cloud Infrastructure: AWS stack (S3, Firehose, Lambda, Athena, etc.), Kubernetes (K8s)
• Nice-to-Have ML/AI Experience: LiteLLM, Hugging Face, XGBoost, etc.
• Proven ability to optimize performance, cost, and scalability of data systems.
• Strong foundation in data governance, quality, security, and observability.
• Collaborative and proactive in cross-functional settings, particularly when enabling AI/ML initiatives.

We have:

• A product that positively impacts people's lives every single day.
• A team of amazing people with a shared vision and the infinite drive to make it happen
