Hi there! If you’re looking for a high-impact position in an ambitious software house, we’ve got a match for you!

We are looking for a Node.js Engineer to work with a leading consumer purchase insights company that leverages AI and fully permissioned data from 100M+ consumers to transform purchase signals into actionable business and marketing insights.


You will join our core engineering team and work closely with the Lead Engineer. You’ll help expand and future-proof a mission-critical RESTful API that powers insights from massive-scale credit card transaction data. This is not a standard CRUD environment, because our client processes 200+ billion rows. We are looking for someone who writes high-performance SQL, and understands distributed systems.

The current stack includes Node.js, Apigee, AWS (Redshift, RDS Postgres, S3). You’ll maintain this high-performance environment while helping drive a migration toward a modern, serverless, Snowflake-based architecture.

Working hours: up to a maximum of 6:30 PM CET, with particular importance placed on availability during the final hours of the workday.

What will be your responsibilities?

  • Build and maintain scalable RESTful APIs using Node.js.
  • API Development.
  • Define and maintain Swagger / OpenAPI specifications.
  • Write complex, highly optimized SQL for datasets exceeding 200B+ rows.
  • Partner with the Lead Engineer to migrate legacy services into a Snowflake-centric, serverless ecosystem.
  • Data Pipeline Integration.
  • Work across AWS S3, Redshift, and RDS Postgres to ensure high data integrity and efficient data flows.
  • Performance Tuning.
  • Monitor and improve performance across both the Node.js layer and database layer.

Requirements

  • Production-level Node.js backend experience (high-traffic APIs).
  • Expert SQL skills: indexing, query planning, and performance tuning at massive scale.
  • Experience working with data warehouses and large-scale analytics.
  • Experience designing APIs with Swagger/OpenAPI.
Nice to have:
  • Familiarity with Apigee.
  • Experience with Snowflake or other cloud native data warehouses.
  • Strong experience with AWS (S3, RDS/Postgres, Redshift).
