Why This Role Exists

This role exists to scale and stabilize the core data infrastructure powering our real-time analytics and decision systems. You’ll help us deliver accurate, zero-latency business insights by designing robust ingestion pipelines, building clean semantic models, and maintaining rock-solid data governance across the platform.

What You’ll Drive

Architecture & Data Modeling

- Design and implement scalable data transformation layers, organizing raw data into validated, production-grade data marts.
- Build and optimize semantic layer models, ensuring consistent metrics and definitions across all reporting surfaces.
- Establish data modeling standards utilizing optimal storage formats (Parquet, ORC, AVRO) and storage engines (PostgreSQL, ClickHouse, Redshift/BigQuery).

Pipeline Delivery & Execution

- Ship and maintain end-to-end data ingestion pipelines integrating internal services and third-party event streams (Kafka, Kinesis, external APIs).
- Automate data quality and integrity testing to catch pipeline breaks and silent schema drifts before they reach downstream consumers.
- Tune query performance and pipeline bottlenecks, actively managing indexing, data partitioning,



and job scheduling.

Platform Operations & Integration

- Expose data-centric services by building and managing performant REST APIs using modern frameworks (FastAPI, Flask, or Aiohttp).
- Enforce granular access control across our data layers via RBAC, row-level security (RLS), and column-level masking.
- Automate CI/CD workflows and deployments using Docker, GitLab CI, and Terraform across our cloud infrastructure.

Engineering Quality & Cross-Team Alignment

- Partner with product managers, software engineers, and analysts to translate business logic into maintainable technical requirements.
- Participate in thorough code and architecture reviews, upholding strict testing standards (unit, integration, TDD/BDD).
- Document system designs and data catalog schemas, making data discoverable and self-serve across the organization.

What Makes You a GR8 Fit

Must-have

- 3+ years of production experience in Data Engineering, Software Engineering, or related distributed data systems.
- Proven SQL & Database expertise: Strong hands-on work with relational databases (PostgreSQL) and modern analytical/columnar data warehouses (ClickHouse, BigQuery, or Redshift).
- Demonstrated pipeline & distributed compute skills: Practical experience orchestrating distributed jobs (Spark, Trino, Flink)



and handling event streaming engines (Kafka, RabbitMQ, or Kinesis).
- Solid software engineering foundations: Proficient in writing clean, modular Python for data applications, pipeline orchestration, and REST APIs.
- Linux, Container, & CI/CD literacy: Comfortable writing Dockerfiles, configuring CI/CD pipelines (GitLab CI, GitHub Actions), and utilizing Git version control.
- Data quality discipline: Direct experience implementing automated data testing, schema validation, and pipeline observability.

Nice-to-have

- Hands-on experience with Infrastructure as Code (Terraform) and AWS cloud services.
- Practical exposure to metadata management tools (DataHub, OpenMetadata).
- Understanding of resilience patterns in distributed systems (circuit breakers, rate limiting, connection pooling).
- Degree in Computer Science, Software Engineering, or equivalent practical experience.
