Data Engineer

Job Description: Data Engineer

As a Data Engineer, you will own the end-to-end lifecycle of our data infrastructure. You will

design and implement robust, scalable data pipelines and architect modern data solutions

using a best-in-class technology stack. Your work will transform raw, messy data into clean,

reliable, and actionable data products that power decision-making across the business.

You’ll collaborate cross-functionally with product managers, data analysts, data scientists,

and software engineers to understand data needs and deliver high-performance data

solutions. Your impact will be measured by how effectively data is delivered, modeled, and

leveraged to drive business outcomes.

Key Responsibilities:

● Architect & Build: Design, implement and manage cloud-based data platform using a

modern ELT (Extract, Load, Transform) approach.

● Data Ingestion: Develop and maintain robust data ingestion pipelines from a variety of sources, including operational databases (MongoDB, RDS), real-time IoT streams, and

third-party APIs using services like AWS Kinesis/Lambda or Azure Event Hubs/Functions.

● Data Lake Management: Build and manage a scalable and cost-effective data lake on

AWS S3 or Azure Data Lake Storage (ADLS Gen2), using open table formats like Apache

Iceberg or Delta Lake.

● Data Transformation: Develop, test, and maintain complex data transformation models using dbt. Champion a software engineering mindset by applying principles of version control (Git), CI/CD, and automated testing to all data logic.

● Orchestration: Implement and manage data pipeline orchestration using modern tools like Dagster, Apache Airflow, or Azure Data Factory.

● Data Quality & Governance: Establish and enforce data quality standards. Implement automated testing and monitoring to ensure the reliability and integrity of all data assets.

● Performance & Cost Optimization: Continuously monitor and optimize the performance and cost of the data platform, ensuring our serverless query engines and storage layers are used efficiently.

● Collaboration: Work closely with data analysts and business stakeholders to

understand their needs, model data effectively, and deliver datasets that power our BI

tools (Metabase, Power BI).

Required Skills & Experience (Must-Haves):

● 3+ years of professional experience in a data engineering role.

● Expert-level proficiency in SQL and the ability to write complex, highly-performant queries.

● Proficient in Python based data cleaning packages and tools. Experience in python is a must.

● Hands-on experience building data solutions on a major cloud provider (AWS or Azure), utilizing core services like AWS S3/Glue/Athena or Azure ADLS/Data Factory/Synapse.

● Proven experience building and maintaining data pipelines in Python.

● Experience with NoSQL databases like MongoDB, including an understanding of its data modeling, aggregation framework, and query patterns.

● Deep understanding of data warehousing concepts, including dimensional modeling, star/snowflake schemas, and data modeling best practices.

● Hands-on experience with modern data transformation tools, specifically dbt.

● Familiarity with data orchestration tools like Apache Airflow, Dagster, or Prefect.

● Proficiency with Git and experience working with CI/CD pipelines for data projects.

Preferred Skills & Experience (Nice-to-Haves):

● Experience with real-time data streaming technologies, specifically AWS Kinesis or Azure Event Hubs.

● Experience with data cataloging and governance tools (e.g., OpenMetadata, DataHub, Microsoft Purview).

● Knowledge of infrastructure-as-code tools like Terraform or CloudFormation.

● Experience with containerization technologies (Docker, Kubernetes).
