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 (the open-source, durable execution engine originating from Uber/Cadence) to build resilient, distributed stateful workflows and data pipelines. A core focus of this position is establishing robust data schema design and automated validation to ensure strong data contracts across distributed systems. Alongside these technologies, you will design robust batch and streaming ETL/ELT pipelines leveraging Python, Apache Spark, and modern cloud data warehouses/lakehouses.Key ResponsibilitiesStream 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 storageResilient 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 tasksPipeline Development: Build end-to-end batch and near-real-time pipelines using Python, SQL, and Apache Spark / PySparkData Modeling & Warehousing: Design and optimize analytical data models (dimensional/star schema) in modern cloud data warehouses/lakehouses (e.g., Snowflake, BigQuery, Databricks, Redshift)Reliability & Data Quality: Implement automated testing, continuous schema validation, data drift detection, and observability across streaming and batch workflowsCross-Functional Collaboration: Partner with software engineers, machine learning engineers, and analysts to define standard schema definitions, data contracts, and production-grade CI/CD release patternsRequired Experience4+ years of professional experience in data engineering, backend distributed systems, or software engineeringHands-on experience with Temporal (or Cadence): Proven understanding of durable workflows, activities, retries, signals, queries, and long-running distributed task orchestrationDeep expertise with Apache Kafka: Practical experience with message partitioning, consumer groups, offset management, and topic designStrong 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 standardsDistributed computing experience: Hands-on development with Apache Spark (PySpark/Spark SQL) processing large-scale datasetsAdvanced SQL & Data Modeling: Strong experience with relational databases, dimensional data modeling, and query performance tuningInfinitive is required by law in some jurisdictions to include a reasonable estimate of the compensation range for this role.
