– Write clean, maintainable, well-tested code across the stack
– Troubleshoot performance bottlenecks across data ingestion, storage, and visualization layers

– Strong proficiency in at least one backend language such as Python, Go, or Node.js/TypeScript
– Front-end development experience with React, Next.js, and TypeScript
– Experience building or working with data pipelines, ETL processes, or web scraping/crawler infrastructure
– Comfortable working in a high-growth, early-stage engineering environment with evolving priorities
– Must be authorized to work in the United States without sponsorship
Preferred Qualifications:
-Experience with data visualization libraries such as D3, Cytoscape, Sigma.js, vis.js, or Recharts, particularly for graph/network visualizations
– Experience with social listening, social media data, or large-scale web data platforms
– Familiarity with Elasticsearch, OpenSearch, Redis, or Airflow
– Prior experience at a seed-to-Series B startup
– Experience with AWS, GCP, Docker, or Kubernetes
Tools & Technology:
– Graph database platforms (Neo4j, TigerGraph, Dgraph, ArangoDB, or similar)
– Streaming/data pipeline tools (Kafka, Spark, Flink, or similar)
