Description
We are seeking a talented Senior Data Engineer to join our dynamic team. In this hybrid data engineering and backend development role, you will collaborate across functions to design, build, and deploy end-to-end solutions for data acquisition, processing, analytics, and visualization. You'll continuously identify opportunities to extract deeper insights from existing data, source new data streams, and rigorously validate data quality and processing pipelines. You'll also build custom, interactive visualizations and partner with product teams to integrate analytics and reporting directly into web applications. If you bring deep expertise in Python, SQL, and event-driven messaging, strong backend skills in Go, and hands-on experience with D3.js visualization, this is a unique opportunity to drive meaningful impact atone of the most innovative companies in the world.
Responsibilities:
Design, develop, and maintain scalable data pipelines and backend micro services using Python and Go.
Manage structured and unstructured data flowing through PostgreSQL, Snowflake, S3, and NATS messaging infrastructure.
Build custom, interactive data visualizations using D3.js to power internal dashboards and user-facing analytics features.
Write highly optimized SQL queries and administer PostgreSQL databases, including schema design, advanced data modeling, and query performance tuning.
Architect and integrate event-driven systems using NATS for real-time streaming, batch processing, and reliable inter-service communication.
Refactor and modernize legacy backend codebases to improve performance, security, and long-term maintainability.
Own features end-to-end: from technical design and development to testing, deployment, and monitoring.
Collaborate with cross-functional teams on REST/async API design, debugging, and system performance optimization.
Actively participate in code reviews, technical architecture discussions, and engineering best practices.
Stay current with emerging data engineering and backend technologies, proposing and implementing improvements to our development workflows.
Preferred Qualifications
Experience translating ambiguous business requirements into clear, scalable technical solutions.
Familiarity with OpenAPI/Swagger for REST APIs and AsyncAPI for event-driven services.
Experience implementing observability stacks using Prometheus metrics and OpenTelemetry/Jaeger distributed tracing.
Deep understanding of message brokers (NATS, Kafka, Redis Streams) and stream processing patterns.
Experience with cloud object storage (S3-compatible) and caching layers (Redis-compatible).
Proficiency with CI/CD pipelines, containerization (Docker), and infrastructure-as-code concepts.
