Role & Responsibilities – What You’ll Actually Do

Designing & Building Production Data Pipelines: Your core responsibility involves architecting and implementing batch and real-time data pipelines moving data from various sources (application databases, third-party APIs, event streams, file uploads) into Cornerstone’s analytics infrastructure. This means writing Python/SQL code defining extraction logic, transformation rules, and loading procedures; configuring Fivetran connectors for automated data ingestion; building dbt models transforming raw data into business-ready dimensions and facts; and orchestrating entire workflows through Apache Airflow DAGs ensuring pipelines run reliably on schedule.

Data Infrastructure Maintenance & Optimization: Beyond building new pipelines, you maintain existing data infrastructure ensuring accuracy, performance, and scalability. This involves monitoring Snowflake query performance identifying slow queries needing optimization, managing data warehouse costs by implementing clustering/partitioning strategies reducing compute consumption, troubleshooting failed pipeline runs investigating root causes (schema changes, API rate limits, data quality issues), and implementing data quality checks validating completeness and correctness before downstream consumption.

ETL Process Development: Extract-Transform-Load remains fundamental to data engineering. You develop ETL processes extracting data from MySQL/PostgreSQL databases powering Cornerstone applications, SaaS tools like Salesforce/Zendesk storing customer data, flat files uploaded by clients, and REST APIs providing real-time events. Transformation logic cleanses dirty data (handling nulls, deduplicating records, standardizing formats), enriches datasets joining multiple sources, aggregates granular transactions into summary metrics, and structures data following dimensional modeling principles optimizing analytical queries.

Workflow Automation: Manual data processes don’t scale. You automate everything – data ingestion pipelines triggered automatically when new files land in S3 buckets, aggregation jobs running nightly computing yesterday’s metrics, ETL processes self-healing when minor failures occur (retrying failed API calls, skipping corrupted records with alerts), and dependency management ensuring downstream jobs only run after upstream data arrives successfully. Apache Airflow becomes your orchestration tool defining these complex workflows as code.

Data Product Development for Analytics Teams: Data scientists and business analysts need curated, trustworthy datasets optimized for their tools (Tableau, Looker, Python notebooks). You build data products – dimensional models enabling self-service reporting, aggregated tables speeding dashboard load times, feature stores providing ML-ready data for model training, and APIs exposing data programmatically for advanced analytics use cases. This requires understanding stakeholder needs translating vague requests like “we need customer success metrics” into concrete data structures with clear definitions.

Machine Learning Model Deployment: Unlike typical data engineers who just “prepare data for data scientists,” Cornerstone expects you partnering with ML teams deploying models into production. This means building inference pipelines scoring new data through trained models, creating feedback loops capturing model predictions and actual outcomes for retraining, implementing A/B testing infrastructure comparing model variants, monitoring model performance detecting drift when predictions degrade, and automating retraining pipelines keeping models current as data distributions change.

Data Governance & Compliance: With 180+ countries and strict regulations like GDPR, CCPA, and industry-specific compliance, you implement data controls ensuring privacy, security, and regulatory adherence. This involves masking personally identifiable information (PII) in non-production environments, implementing row-level security restricting data access based on user roles, maintaining audit logs tracking who accessed what data when, encrypting sensitive fields, and documenting data lineage showing exactly how raw inputs transform into final outputs for regulatory audits.

Performance Monitoring & Optimization: Data systems require constant tuning. You monitor Snowflake warehouse utilization identifying over/under-provisioned resources, analyze query patterns finding frequently-run expensive queries benefiting from materialized views, implement incremental loading strategies reducing full-table scans, optimize dbt model dependencies eliminating unnecessary computation, and configure caching layers accelerating repetitive analytical queries.

Must-Have Technical Skills

Advanced SQL & Database Design (Non-Negotiable): You need expert-level SQL – complex joins across multiple tables, window functions for advanced analytics, CTEs organizing logic readably, query optimization using EXPLAIN plans, and database design understanding normalization, indexing strategies, and when to denormalize for performance. This isn’t “I can write SELECT * FROM table” SQL; this is “I can debug a 500-line SQL script and optimize it from 10 minutes to 30 seconds” proficiency.

Cloud Data Warehouse Expertise: Snowflake experience highly preferred (mentioned twice in job description), but exposure to Databricks, Apache Spark, Redshift, or BigQuery also valuable. You should understand cloud data warehouse architectures (separation of storage/compute), cost optimization strategies, semi-structured data handling (JSON/Parquet), and integration with cloud ecosystems.

Data Ingestion Tools: Hands-on experience with Fivetran, Stitch, or Matillion automating ELT from SaaS applications and databases into data warehouses. Understanding connector configuration, handling schema changes, monitoring sync health, and troubleshooting failures.

Cloud Platform Knowledge: Working knowledge of AWS (S3, Lambda, Redshift, Glue), Azure (Data Factory, Synapse, Blob Storage), or GCP (BigQuery, Cloud Functions, Cloud Storage). You don’t need cloud architect-level expertise but should navigate cloud consoles, understand IAM permissions, configure basic resources, and leverage cloud services for data workflows.

Programming Proficiency: Python mastery essential – pandas for data manipulation, requests for API interactions, unit testing frameworks (pytest), OOP design patterns, and writing production-quality code following best practices. Java, C++, or Scala knowledge adds value. Bash scripting for automation, deployment scripts, and infrastructure management.

Data Pipeline & Workflow Tools: Apache Airflow experience critical (explicitly mentioned) – writing DAGs, managing dependencies, monitoring execution, handling failures, and implementing best practices. Familiarity with dbt for transformation logic, version control (Git), CI/CD pipelines, and orchestration patterns.

Machine Learning Deployment: Experience taking trained models and putting them into production environments – creating inference endpoints, handling real-time/batch scoring, monitoring predictions, and building retraining pipelines. This separates data engineers from ETL developers.

Bonus Skills (Nice-to-Have):

NoSQL Databases: MongoDB, Redis, Cassandra, Neo4j, CrateDB for handling document stores, caching layers, graph databases, or time-series data.

Big Data Technologies: Hive, Hadoop, Spark, Presto, MapReduce for distributed computing on massive datasets exceeding single-machine processing capabilities.

Required Skills Summary (Single Line): Advanced SQL and relational database design expertise, hands-on experience with Snowflake/Databricks/Spark cloud data warehouses, proficiency in data ingestion tools (Fivetran/Stitch/Matillion), working knowledge of cloud platforms (AWS/Azure/GCP), strong Python/Java/C++/Scala programming with OOP principles, Bash scripting abilities, proven experience with Airflow pipeline orchestration, machine learning model deployment in production, excellent problem-solving and communication skills, and ability to work independently and collaboratively with cross-functional teams.
