Required Skills & Qualifications:
● 1+ years of professional experience in data engineering or backend systems with a focus on scalable systems.
● Strong hands-on experience with Python or Scala, and writing efficient, production- grade code.
● Deep understanding of data engineering concepts: data modeling, data warehousing, data lakes, streaming vs. batch processing, and metadata management.
● Solid experience with AWS (S3, Redshift, EMR, Glue, Lambda) or equivalent cloud platforms.
● Experience working with orchestration tools like Apache Airflow (preferred) or similar (Azkaban, Luigi).
● Proven expertise in working with big data tools such as Apache Spark, and managing Kubernetes clusters.
● Proficient in SQL and working with both relational (Postgres, Redshift) and NoSQL (MongoDB) databases.
● Ability to understand API-driven architecture and integrate with backend services as part of data pipelines.
● Strong problem-solving skills, with a proactive attitude towards ownership and continuous improvement.
