About the Role

We are looking for a Big Data Engineer to design, build, and operate large-scale data pipelines and analytical infrastructure that transform high-volume raw data into reliable, query-ready datasets for analytics, reporting, and data-driven products.

Our data platform ingests and processes data from multiple sources and serves analytics, data science, product, and downstream applications. In this role, you will own data pipelines end-to-end-from ingestion and transformation to warehousing, orchestration, data quality, and observability.

A key part of the role is owning ClickHouse as our primary analytical data store . You will be responsible for designing scalable data models, optimizing query performance, and ensuring the platform remains reliable and cost-efficient as data volumes and workloads grow.

You will work closely with data scientists, analysts, product engineers, and other engineering teams to build a modern, cloud-native data platform.

What Youll Do

Design, build, and maintain robust batch and streaming data pipelines that ingest data from multiple sources into analytical data stores.
Build and operate Apache Airflow DAGs , including scheduling, dependencies, retries, backfills, idempotency, concurrency, and failure handling.
Develop analytics-ready datasets using dbt , following well-structured staging, intermediate, and mart layers with appropriate tests, documentation, and incremental models.
Own ClickHouse as the primary analytical store, including:
- Schema and table design using the MergeTree family of engines
- Partitioning and sorting/primary key strategies
- Materialized views
- Distributed and replicated table architectures
- Query and memory optimization
- High-volume data ingestion and performance tuning
Work with BigQuery where cloud data-warehouse patterns are appropriate, including data modeling and query/cost optimization.
Design and operate NoSQL and key-value data stores , including Bigtable, DynamoDB, and Redis, based on specific access patterns and performance requirements.
Build and maintain data-quality frameworks covering validation, testing, freshness, completeness, reconciliation, and anomaly detection.
Implement monitoring, alerting, structured logging, and observability for data pipelines and services.
Own pipeline SLAs, incident response, troubleshooting, and root-cause analysis.
Manage backfills, safe re-runs, schema evolution, and data migrations while minimizing downstream impact.
Build reproducible, containerized environments using Docker and contribute to CI/CD and Infrastructure as Code practices.
Partner with analysts, data scientists, product managers, and product engineers to translate business and technical requirements into scalable data models and pipelines.
Continuously improve pipeline reliability, scalability, performance, and infrastructure cost efficiency.

Must-Have Requirements

4-6 years of experience in data engineering or a closely related field, with strong hands-on production experience.
Expert-level SQL and strong Python skills, with experience writing production-grade, maintainable, and well-tested code.
Strong hands-on experience with Apache Airflow or a comparable workflow orchestration platform, including DAG design, scheduling, retries, backfills, dependency management, idempotency, and concurrency.
Hands-on experience with dbt or a comparable transformation/ELT framework, including modular models, testing, source management, documentation, and incremental processing.
Expert-level production experience with ClickHouse . This is a core requirement and should include:
- MergeTree engine family
- Partitioning and primary/sorting keys
- Materialized views
- Distributed and replicated tables
- Query and memory optimization
- High-volume ingestion and performance tuning
Production experience with a cloud-based columnar/OLAP warehouse , such as BigQuery, including data modeling and performance/cost optimization.
Hands-on experience with NoSQL and key-value databases , such as Bigtable, DynamoDB, and Redis, including data modeling, partition/key design, access patterns, and caching strategies.
Strong understanding of ETL/ELT and dimensional/layered data modeling principles.
Experience with GCP and/or AWS and familiarity with Docker, Git, and CI/CD .
Strong focus on data quality, reliability, observability, and correctness .
Strong ownership, problem-solving, and communication skills, with the ability to collaborate effectively across engineering, analytics, data science, and product teams.

Nice-to-Have

Experience with search platforms such as Elasticsearch, OpenSearch, Apache Solr, or Vespa, including indexing pipelines, schema design, and relevance/performance tuning.
Experience with Aerospike or other high-performance, low-latency distributed key-value/NoSQL systems.
Experience building streaming and event-driven pipelines using Kafka, Pub/Sub, or similar technologies.
Experience with Change Data Capture (CDC) patterns and technologies.
Experience with Apache Spark and data-lake architectures using object storage such as GCS or S3.
Experience with Terraform or other Infrastructure as Code tools and Kubernetes .
Experience with data-quality and observability tools such as Great Expectations, Soda, Monte Carlo, or advanced dbt testing .
Understanding of data platform cost optimization / FinOps practices.
Experience handling high-volume e-commerce, product catalog, behavioral, or event data .
Familiarity with a second backend programming language, particularly Go .

What Success Looks Like

Data pipelines are reliable, well-tested, observable, and consistently meet freshness and completeness SLAs .
Data models are clean, scalable, documented, and trusted by analytics, data science, and product teams.
Data-quality issues are identified before they impact downstream consumers .
Pipeline failures are diagnosed and resolved quickly, with clear root-cause analysis and preventive actions.
ClickHouse and the broader analytical platform scale smoothly with growing data volumes and query workloads .
Data infrastructure remains performant and cost-efficient as usage grows.
Downstream teams can confidently rely on the platform for analytics, reporting, experimentation, and data-driven product experiences .
