The Opportunity

As a Senior Test Automation Engineer, you will be responsible for taking on a leading role in the QA automation of multiple Kargo products and will be integral in mentoring and guiding others. Your focus will be in our internal and self-serve web apps for buying and managing advertising campaigns.

You should be comfortable working alongside Engineering, Product, and Design teams to develop clean code. Ultimately, you will help shape and define our creative and collaborative processes and will follow a best practice approach to producing high-performing products.

The Daily To-Do:

• You will work to improve and build the automation tools of our internal and self-service web apps to improve upon the reliability of the platforms.

• You will help decide the right tool and/or testing framework that will best fit the problem at hand.
• You will help define guidelines and best practices that the QA team will follow in order to improve test coverage and reliability.
• You will recognize when patterns of bugs point to necessary refactors and work to implement tests and monitoring to prevent similar issues in the future.
• You will participate in architecture planning, code reviews, and learning sessions to help spread knowledge, and you will be responsible for managing/upgrading the deployment processes of the products you work with.
• You are expected to be a mentor to others on your team - both by fielding questions as well as by proactively identifying situations where more junior developers may need your help. You are the go-to engineer for advice and help from your peers.
• You will identify and initiate investigations into new technologies, prototype and test solutions for product features, and design and validate production designs that deliver exceptional user experiences
