Opportunity

We’re seeking a Senior Data Engineer who is equal parts builder, teacher, and problem solver. You will architect and deliver modern, cloud-first data platforms; mentor teammates; and drive standards that improve reliability, performance, and developer experience. You’ll work across batch and streaming patterns, structured and semi-structured data, and collaborate closely with analysts, product, and engineering teams to turn requirements into scalable, maintainable solutions.

What you'll do:

Design and evolve our data architecture leveraging Apache Iceberg on S3 and Snowflake, balancing performance, reliability, and cost.
Lead continuous improvement of schemas, data models, pipelines, and engineering standards, own design docs and review forums.
Plan and coordinate data migrations with zero/low downtime patterns, including backfills, cutovers, and data validation.
Standardize data contracts and enforce quality checks throughout pipelines and transformations.
Implement and operate Iceberg tables: catalog strategy (AWS Glue), partition transforms, schema evolution, and time-travel/snapshot management.
Optimize data layout (partitioning, clustering, file sizing, compaction) to improve read/write performance and control costs across engines.
Build and maintain batch and streaming pipelines using Airflow, AWS Glue, Step Functions, Lambda, Kinesis, and Snowflake.
Design normalized and dimensional models; apply partitioning and clustering strategies appropriate to Iceberg and target engines.
Own SQL and Spark performance tuning, job optimization, and cost governance (e.g., Snowflake warehouse sizing, query profile analysis).
Establish SLAs, lineage, tests, alerts, and runtime metrics; integrate data quality checks into CI/CD and orchestration.
Mentor and pair program; elevate craftsmanship, testing, reliability, and operational excellence.
Promote security best practices, governance, and compliance-by-default patterns for sensitive data.
Provide documentation, code examples, and training that enable partners to self-serve; champion code reviews and design best practices.

Who you are:

4+ years of professional data engineering experience delivering production-grade pipelines and data platforms.
Strong problem-solving and analytical skills; track record of decomposing complex problems and shipping pragmatic solutions.
Excellent communication and documentation; teacher/mentor who raises the bar for the team.
Proficiency in Python and SQL; experience with Java or Scala a plus.
Solid software engineering practices: Git/GitHub, branching, code review, testing (Pytest/JUnit), and CI/CD.
Hands-on experience operating Apache Iceberg on AWS (S3 + Glue); deep familiarity with Parquet/ORC.
Operating Iceberg with Spark (PySpark/Spark SQL); exposure to Snowflake Iceberg Tables and/or Trino/Presto is a plus.
Practical knowledge of Iceberg concepts: metadata/manifest layers, partition transforms, schema evolution, snapshots/time-travel/branching, row-level deletes/merges, compaction, and vacuum/snapshot expiration.
AWS expertise: S3, Lambda, EventBridge, Glue, Athena, EMR, Kinesis, Step Functions, SQS; cost/performance governance across services.
Snowflake proficiency; experience exposing Iceberg data via Snowflake external or Iceberg tables; Redshift/BigQuery a plus.
Strong SQL performance tuning across at least one engine (Snowflake, PostgreSQL/RDS, MySQL).
Observability with Datadog and/or CloudWatch; strong log analysis, performance profiling, and incident response.
Practical use of AI coding assistants (GitHub Copilot, Amazon Q Developer, ChatGPT, Claude) (nice to have
