About The Position

Kajabi is hiring an Engineer to join our Commerce team and help build the systems that power payments, checkout, subscriptions, and monetization at Kajabi. You'll work across product reliability, financial compliance, and user experience — owning systems that are core to how our creators run their businesses.This role requires solid skills in Ruby on Rails, React, and Postgres, combined with hands-on experience using AI tooling, including agents, to drive smarter workflows and user-facing features.

Requirements

You're product-minded and curious about how users buy, sell, and manage revenue, and you care about building trustworthy financial experiences.
You've shipped production features in commerce, payments, or adjacent domains and understand how changes can impact conversion, churn, or revenue.
You have hands-on experience working with Stripe APIs or similar payment providers and are motivated to keep deepening that expertise.
You take ownership of the systems you work in. You know how they're built, why they're built that way, and how they behave in production.
You balance speed and quality, valuing clear code, testing, and safe, incremental changes — especially in systems that handle money.
You're comfortable working across the stack in Ruby on Rails, React, and Postgres.
You have clear opinions on what makes you effective, and you're actively working to refine those opinions through collaboration with your team.
You're comfortable investigating issues, querying data, and asking thoughtful questions to understand system behavior and user impact.
You communicate clearly in code, pull requests, and team discussions, and you engage with your team about how to improve how you all work together.
