Costco needs a Quality Engineer in Hialeah, FL who can context-switch between C# and Kafka without losing the plot or their patience. At Costco the $94,000 - $134,000 matters, sure, but so does owning the technology outcome with 5 years of Written Communication behind it.

Key Responsibilities

• Prototype proof-of-concept solutions for emerging technology requirements
• Guard the Agile codebase quality through reviews that teach as much as they catch
• Sketch Selenium sequence diagrams that make the technology flow obvious to everyone
• Scale data pipelines processing millions of events with Kafka
• Investigate, diagnose, and fix bugs reported by users and monitoring tools
• Develop and maintain RESTful APIs powering core Costco products
• Ship GraphQL experiments fast, kill the losers, and double down on what sticks

What You'll Bring

• Comfortable owning projects from concept through delivery
• Critical thinking skills and sound, independent judgment
• Real Kafka chops, plus the GraphQL curiosity to keep growing
• Demonstrated ability to manage competing priorities under tight deadlines

From a Hialeah loft, Costco has built an experiment-friendly reputation for solving technology problems others quietly gave up on. Disagreement is welcome here, but once we decide, the whole Costco team rows in the same direction.

We trade fair $94,000 - $134,000 for your talent and throw in mentorship, benefits, and a flexibility policy people actually use.

Just updated, just confirmed, just waiting on the right applicant.
