If you want to be part of a company moving fast, raising the bar, and building something that actually matters - welcome in.

Kajabi is hiring an Engineer to join our Commerce team and help build the systems that power payments, checkout, subscriptions, and monetization '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.

• Own and contribute code across the commerce systems your team is responsible for, including checkout flows, subscriptions, invoicing, and tax-related logic, using Ruby on Rails.
• Build and improve React-based user interfaces that make payment and monetization workflows clear, intuitive, and reliable for our creators.
• Integrate and use AI tooling and agents to improve development workflows and support user-facing product features.
• Collaborate with Product, Design, QA, and Data partners to deliver features that meet user needs and performance goals.
• Communicate clearly about what's needed when working with teammates on shared parts of the system — whether that's defining API contracts, explaining UI states, or making sure test coverage is solid.
• Write clean, testable, and maintainable code, and contribute thoughtful, constructive feedback in code reviews.
• Support the reliability and security of payment systems by following PCI compliance and fraud prevention best practices.
• Contribute to monitoring and observability efforts using Datadog, helping identify, troubleshoot, and resolve production issues.
• Understand how the systems you own are deployed and monitored, and participate in incident response and triage when issues arise.

• 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.

• International payments and currency support.
• Contributions to open-source Rails or React projects.
• Building tools for content creators.
• Product analytics tools (e.g., Amplitude, Looker, Hex, Rudderstack).
• Deploying on cloud-based infrastructure and monitoring via Datadog.
