About the Role

We are seeking an experienced Data Engineer to help design, build, and scale our next-generation event-driven data platforms. In this role, you will be instrumental in bridging high-throughput distributed streaming with complex, fault-tolerant workflow orchestration and strict data governance.

You will work extensively with Apache Kafka for real-time event streaming and Temporal for durable workflow orchestration, building resilient, distributed, stateful workflows and data pipelines. A key focus will be designing data schemas and implementing automated validation to enforce reliable data contracts across distributed systems. You will also develop batch and streaming ETL/ELT pipelines using Python, Apache Spark, and modern cloud data warehouses and Lakehouse platforms.

You will also develop batch and streaming ETL/ELT pipelines using Python, Apache Spark, and modern cloud data warehouses and Lakehouse platforms.

Key Responsibilities

• Stream Processing & Messaging: Architect, deploy, and maintain high-volume distributed data streams using Apache Kafka (producers, consumers, Kafka Connect, Schema Registry).

• Data Schema Design & Validation: Establish and enforce schema design standards, versioning strategies, and automated schema validation (e.g., Avro, Protobuf, JSON Schema) to maintain strict data contracts across microservices, streaming consumers, and Lakehouse storage.

• Resilient Workflow Orchestration: Design and implement durable execution workflows using Temporal to coordinate long-running distributed pipelines, compensate transactions (Saga pattern), and manage cross-system ETL tasks.

• Pipeline Development: Build end-to-end batch and near-real-time pipelines using Python, SQL, and Apache Spark / PySpark.

• Data Modeling & Warehousing: Design and optimize analytical data models (dimensional/star schema) in modern cloud data warehouses / Lakehouse (e.g., Snowflake, BigQuery, Databricks, Redshift).

• Reliability & Data Quality: Implement automated testing, continuous schema validation, data drift detection, and observability across streaming and batch workflows.

• Cross-Functional Collaboration: Partner with software engineers, machine learning engineers, and analysts to define standard schema definitions, data contracts, and production-grade CI/CD release patterns.

Required Experience

• 4+ years of professional experience in data engineering, backend distributed systems, or software engineering.

• Hands-on experience with Temporal (or Cadence): Proven understanding of durable workflows, activities, retries, signals, queries, and long-running distributed task orchestration.

• Deep expertise with Apache Kafka: Practical experience with message partitioning, consumer groups, offset management, and topic design.

• Strong background in Data Schema Design & Validation:

  • Demonstrated proficiency with schema definition frameworks (Apache Avro, Protocol Buffers/gRPC, or JSON Schema).

  • Practical experience managing schema evolution, compatibility modes (backward/forward/full), and schema registries (e.g., Confluent Schema Registry, AWS Glue Schema Registry).

  • Experience enforcing data validation rules, contract testing, and data quality checks (e.g., Great Expectations, Pandera, Pydantic, dbt tests).

• Strong programming proficiency in Python (Go or Java is a plus) with clean code, design patterns, and unit/integration testing standards.

• Distributed computing experience: Hands-on development with Apache Spark (PySpark/Spark SQL) processing large-scale datasets.

• Advanced SQL & Data Modeling: Strong experience with relational databases, dimensional data modeling, and query performance tuning.
