Credit Karma is a company that helps people understand their credit. Today’s guest, Mason Jones, was brought onto the Credit Karma team to move the company from a monolith to microservices. The company has grown almost four-fold since he joined, and Mason is now a senior staff engineer whose role swings from engineering to project management to technical writing, depending on the project he is working on. Prior to working at Credit Karma, Mason was involved in a number of small start-ups, and he explains how these experiences have translated into very useful skills in his current job. He also explains how he shares these skills with other engineers in the company, and some of the challenges that have arisen during mentoring sessions. Security, velocity and reliability are core values at Credit Karma and Mason shares how he, as a leader, upholds them, and how he continually expands his knowledge in order to have the maximum positive impact on the company.
