Streaming Data Platform Engineer

Streaming Data Platform Engineer

W2 Contract

Pay Rate: $55 - $65 per hour

Location: Cupertino, CA - Remote Role

Job Summary:

We are seeking an experienced software engineer to help design and build large-scale, cloud-native data platform capabilities with a strong emphasis on real-time streaming. This is a platform engineering role, not a conventional ETL or analytics development position. The engineer will create reusable services, SDKs, frameworks, and self-service capabilities that enable internal consumers - including machine learning practitioners - to process, manage, and access high-volume data reliably.

Duties and Responsibilities:

• Design, build, and operate distributed streaming systems using Apache Flink and/or Apache Spark Structured Streaming for high-throughput, low-latency workloads.


• Develop production-grade platform services, APIs, reusable frameworks, and SDKs using Python and/or Java (Spring Boot).


• Contribute to control-plane and data-plane architecture, including workload orchestration, configuration, lifecycle management, and operational reliability.


• Enable scalable data management for ML consumers: dataset organization, efficient access and retrieval, indexing patterns, and repeatable training-data workflows.


• Engineer observability, fault tolerance, checkpointing, recovery, scaling, performance optimization, and automated testing for distributed processing systems.


• Partner with platform teams, application engineers, and ML practitioners to translate use cases into self-service capabilities and well-supported developer interfaces.


• Apply security and governance practices, including authentication, authorization, data protection, and appropriate handling of sensitive datasets.

Requirements and Qualifications:

• Strong hands-on real-time streaming experience with Apache Flink or Apache Spark Structured Streaming in production; able to explain design tradeoffs and incidents.


• Deep understanding of distributed data processing, partitioning, state management, event-time processing, backpressure, and failure recovery.


• Strong software engineering proficiency in Python or Java, including API/service design, automated tests, and maintainable code.


• Experience building data platform capabilities, internal developer platforms, reusable libraries/SDKs, or large-scale backend systems - beyond individual pipelines.


• Experience with microservices, containers, cloud-native deployment, CI/CD, monitoring, and production operations.


• Ability to work across requirements ambiguity, evaluate architecture options, and communicate tradeoffs with engineering stakeholders.


• Hands-on knowledge of both Flink and Spark, plus Databricks or comparable managed distributed-data platforms.


• Experience with Java/Spring Boot and Python in the same platform ecosystem.


• Experience supporting ML practitioners through training-data access, feature/dataset management, data quality, indexing, or governed data interfaces.


• Familiarity with Kafka or comparable event-streaming infrastructure; schema evolution and exactly-once/at-least-once delivery tradeoffs.


• Experience with Kubernetes, service orchestration, cloud object storage, data access governance, and RBAC/ABAC patterns.
