You'll lead the design, build, and optimization of our data infrastructure, from real-time ingestion to supporting machine learning operations. Every choice you make will be data-driven and cost-conscious, ensuring efficiency and impact across the company.
Beyond engineering, you'll be a strategic partner and problem-solver, sometimes diving into advanced analysis or data science tasks. Your work will directly shape how we deliver innovative solutions and support our growth at scale.
Responsibilities:
- Design and Build Data Pipelines
: Architect, build, and maintain our end-to-end data pipeline infrastructure to ensure it is scalable, reliable, and efficient. - Optimize Data Infrastructure
: Manage and improve the performance and cost-effectiveness of our data systems, with a specific focus on optimizing pipelines and usage within our Snowflake data warehouse. This includes implementing FinOps best practices to monitor, analyze, and control our data-related cloud costs. - Enable Machine Learning Operations (MLOps)
: Develop the foundational infrastructure to streamline the deployment, management, and monitoring of our machine learning models. - Support Data Quality
: Optimize ETL processes to handle large volumes of data while ensuring data quality and integrity across all our data sources. - Collaborate and Support
: Work closely with data analysts and data scientists to support complex analysis, build robust data models, and contribute to the development of data governance policies.
Qualifications:
- Bachelor's degree in Computer Science, Engineering, or a related field.
- Experience: 5+ years of hands-on experience as a Data Engineer or in a similar role.
- Data Expertise: Strong understanding of data warehousing concepts, including a deep familiarity with Snowflake.
Technical Skills:
- Proficiency in Python and SQL.
- Hands-on experience with workflow orchestration tools like Airflow.
- Experience with real-time data streaming technologies like Kafka.
- Familiarity with container orchestration using Kubernetes (K8s) and dependency management with Poetry.
- Cloud Infrastructure: Proven experience with AWS cloud services (e.g., EC2, S3, RDS).
Bonus Points:
- Experience implementing FinOps principles, especially in a Snowflake environment.
- Background in MLOps and a passion for deploying machine learning models at scale.
- Knowledge or personal interest in nutrition, metabolism, or health.
- Experience with data visualization tools (e.g., Tableau, Looker).
- Experience with MongoDB or other NoSQL databases.
