How to Apply for Quality Assurance Engineer (PL)

at Chooose

🏢 About Chooose

Chooose is a mission-driven software company focused on enabling the lower carbon fuel value chain, meaning you'll work on technology that directly contributes to reducing carbon emissions. The remote-first culture and emphasis on solving complex, impactful problems make it an attractive place for engineers who want their work to matter.

About This Role

As a Quality Assurance Engineer at Chooose, you'll be the gatekeeper of quality for software that powers the carbon fuel value chain. Your work ensures that complex systems handling NoSQL databases, APIs, and UIs are reliable, which is critical for customers relying on accurate carbon accounting and fuel logistics.

💡 A Day in the Life

You'll start by reviewing new requirements and test cases, then run manual UI and API tests, logging bugs and verifying fixes. Later, you might dive into a production issue reported by a customer, using scripts to query the NoSQL database to trace data flow. You'll also participate in standups and collaborate with developers to improve test coverage.
