Senior Software Engineer, Kajabi

• The right candidate will move with urgency and focus, obsess over product metrics, and be comfortable running frequent A/B tests to move key business outcomes
• If you're excited to write production-ready code one day (and sometimes IN one day) and analyze experiment results the next, this role is for you
• You’re product- and growth-minded—constantly thinking about the “why” behind every interaction and eager to improve it
• You disagree and commit to move forward, execute, and get results, recognizing that data holds power over anecdotal opinions
• You have a proven track record of shipping impactful experiments and features that directly influenced user behavior and business metrics
• You understand A/B testing best practices and are comfortable evaluating experiment design and results
• You think in loops: ship → learn → iterate → scale
• You take a pragmatic approach to engineering—balancing speed and quality to deliver impact without compromising maintainability
• You are confident working across the stack—especially with React, JavaScript, Ruby on Rails, and Postgres—and are comfortable diving into both backend and frontend code
• You thrive in collaborative environments, partnering with product managers, analysts, and designers to solve complex growth challenges. We’re not a delivery team, we’re a growth team all aligned on the same mission and expect everyone to be an owner
• You are comfortable querying data (SQL, dashboards, analytics tools) and advocating for better instrumentation where needed
• You demonstrate resilience and curiosity: most experiments fail, but you find the insights and keep pushing forward
• You communicate clearly and thoughtfully, whether you’re articulating tradeoffs or mentoring teammates
• You design production-aware features and experiments, ensuring safe database rollouts and minimal impact on a high-traffic Postgres system
• You provide technical leadership, feedback, and mentorship to mid-level and junior developers, helping the whole team raise their bar.”
• You use automation and AI-assisted tools to increase delivery speed while preserving quality and maintainability
