Staff Software Engineer - Credit Karma

Overview

The Portals team sits at the heart of how Intuit Credit Karma delivers personalized experiences to its members. As a Senior Software Engineer on this team, you'll own the system that decides — in real time — what each member sees when they open the app. That means working on problems that directly impact millions of people and the financial decisions they make every day. This is a high-leverage role where your work touches nearly every product team at Credit Karma. If a member gets shown the right offer at the right moment, there's a good chance the Portals platform made that happen.

• Drive AI-Native Innovation: Champion the integration of GenAI and machine learning into the platform for smarter content selection and advanced personalization patterns
• Orchestrate Complex Initiatives: Drive high-impact tech initiatives end-to-end, sequencing complex dependencies and managing risks across multiple systems and layers of architecture
• Empower & Velocity-Proof Teams: Build reusable tools, testing infrastructure, and workflows that allow other product and marketing teams across the company to deploy changes faster and safer
• Elevate Engineering Talent: Provide clear goals, facilitate technical design reviews, and give actionable feedback to senior engineers so they can lead projects independently
