Senior/Middle Data Engineer
About the job
- Use Python as a working language for data engineering, not only scripting.
- Use SQL fluently, including window functions, complex joins, and reading and reasoning about execution plans.
- Work with Spark or PySpark transformations, aggregations, window functions, and user-defined functions, and understand shuffle, skew, and partitioning sufficiently to diagnose slow jobs with the Spark UI.
- Have equivalent depth in the AWS data stack, including S3, Glue, Athena, Lambda, Step Functions, and IAM; equivalent experience with GCP or Azure is acceptable.
- Understand lakehouse fundamentals including Parquet, Iceberg or Delta or Hudi, partitioning, compaction, schema evolution, and snapshots.
- Use Airflow, Dagster, Prefect, or Step Functions for orchestration.
- Use Docker and be comfortable running workloads on Kubernetes.
- Use Git and CI/CD and have exposure to infrastructure as code with Terraform or Terragrunt.
- Understand streaming and CDC concepts, including Kafka, delivery semantics, late and out-of-order data, and idempotent writes.
- Debug using logs and metrics, investigate failed jobs, and explain root causes.
- Read and write technical documentation in English.
- For the middle level, have at least 2 years of dedicated data engineering experience, be solid across most of the listed technologies, and be genuinely strong in two or three areas.
- For the senior level, have at least 5 years of experience designing, building, and operating Data Lake or data warehouse solutions; design systems other engineers build on, mentor, and carry technical decisions across team boundaries.
- Have hands-on experience using coding agents such as Claude Code or Codex on production work, including decomposing tasks, supplying context, and iterating to an approvable result.
- Critically review generated code and be able to explain it line by line; retain responsibility for correctness, cost, and compliance.
- Be willing to work outside your strongest area and use AI to become productive with unfamiliar tools.
- A second programming language beyond Python, such as Scala, Java, Go, or Rust, is listed as a bonus.
- Own infrastructure as code by creating Terraform or Terragrunt modules, rather than only editing existing ones, is listed as a nice-to-have.
- Experience with dbt or SQLMesh, data contracts, lineage, and data catalog tools is listed as a nice-to-have.
- Experience with analytical databases such as ClickHouse, Redshift, BigQuery, or Snowflake is listed as a nice-to-have.
- Experience with data modeling such as Kimball or Data Vault, and with regulated or audited data environments, is listed as a nice-to-have.
- Experience building complex analytical systems end-to-end is listed as a nice-to-have.
- Design and build end-to-end data pipelines, from ingestion from heterogeneous sources through cleaning, transformation, enrichment, normalization or denormalization, and publication, including tests, monitoring, and production ownership.
- Make and defend architectural decisions for the assigned area, including file or table formats, partitioning, incremental versus full reloads, latency and cost trade-offs, and failure semantics.
- Translate business cases into requirements, architecture, and code, and challenge requirements when appropriate.
- Identify both a fast path for experimentation and a stable path for production, and choose appropriately between them.
- Continuously identify processing that should be simplified, automated, or removed.
- Experience with RAG, embeddings, MCP servers, agent workflows, or evaluations is a bonus; these technologies are used for metadata search, SQL generation over the data lake, data classification, and quality checks.
