Principal Software Engineer

MediaAlpha is a customer acquisition solutions provider powered by technology and data science. The company provides industry-leading solutions designed to reach consumers shopping within high-consideration categories such as property and casualty insurance, health insurance, life insurance, and more. Hybrid role: 3 days/week in office Role Overview As a Principal Software Engineer at MediaAlpha, you will be a technical leader accountable at the ecosystem level. You own the architecture, health, and strategic technical direction across large and complex systems that span multiple teams—ensuring sound design, operational excellence, and alignment with business needs across the ecosystem. You will shape broad architecture, partner with engineering and business leaders to define roadmaps, and drive technical standards that the organization builds on. Principal Engineers are hands-on technical leaders. You write code, make architectural decisions, and solve the hardest technical problems in the ecosystem. Your work sets the standard for engineering quality and shapes how systems evolve. The difference at this level is that your technical contributions have ecosystem-wide impact—you define the patterns, frameworks, and architectural direction that other engineers build within. Everything we build, decide, and deliver is measured against four pillars: Fast, Flexible, Robust, and Transparent. Principal Engineers serve these pillars through architectural clarity that eliminates wasted motion, systems designed for change and adaptability, patterns and standards that ensure long-term health, and active ambassadorship that makes technical direction visible across the organization. The ideal candidate is a masterful engineer who operates at ecosystem scope—driving technical strategy across teams and groups, shaping architecture that spans organizational boundaries, and developing senior technical leaders. You operate effectively across organizational boundaries, mentor and lead engineers throughout the organization, and drive technical excellence at ecosystem scale. We are an intentionally small organization, designed for agility, speed, collaboration, and workability, where Principal Engineers serve as the technical authorities and go-to leaders across multiple teams and groups.
