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.

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.
