Engineering at Zinc

Engineering team and processes

Our culture is very engineering driven. Our engineers work with our founders, customer support leads, and sales leads to architect new features. Features are largely based on requests from our biggest customers and biggest leads. We deploy early and often, and we've built a robust set of devops tools for continuous deployment and monitoring.

Technical Challenges
  • Ownership over a product that makes $2M ARR and literally pays the bills for thousands of online entrepreneurs (large eBay and Amazon sellers).
  • Scraping sites like Amazon hundreds of times a second for our ultra-high-frequency repricing
Projects you might work on
  • Example project: Implement an onboarding flow for PriceYak based on feedback from users and data we've collected on their usage patterns

  • Example project: Integrate Amazon.de into PriceYak in such a way that makes it easy for us to integrate other European Amazon marketplaces in the future.
