About The Position

We are looking for a Senior Software Engineer to join us at Kajabi. The people who use Kajabi are building real businesses. They're creating transformative learning experiences. Showing up for their customers and communities every day. What we ship becomes part of how they do that work. That's the weight of this job, and it's what makes it worth doing. Our founders just came back to lead the company. The energy is different now. An ambition to take big swings, ship fast, and build something that matters to real people. That's the moment you'd be walking into. We're obsessed with getting it right. The interaction that feels just right. The moment that makes someone stop and say "wow." Experiences that feel obvious in use. Clear, stable, and thoughtfully composed. Here's what that actually looks like. Kajabi is hiring a Senior Software Engineer to join our engineering team in Irvine, Ca. This is a full time, in-person role at our headquarters. You'll work on a cross-functional product team, owning systems and features that directly impact how thousands of creators build their businesses. This isn't a heads-down coding role. Senior Software Engineers here are expected to think like product owners, ship like engineers, and use AI tools to do both faster. You'll bring technical judgment into product conversations, shape what gets built and why, and help the team deliver solutions that customers actually value.

Requirements

Strong, hands-on experience with Ruby on Rails, React, and Postgres. Comfortable across the full stack.
Use AI tools as a real part of your workflow, not just occasionally. Know how to get the most out of them and review AI-generated output with the same rigor you'd apply to any other code.
Think about what you're building, not just how. Care whether the product actually solves a real problem for real users.
Make pragmatic decisions. Not afraid to push back, but once the team is aligned, commit and execute.
Shipped and operated features in a high-traffic SaaS environment and understand what it takes to keep systems running well.
Experienced with cloud deployment on AWS, and comfortable with supporting infrastructure like Sidekiq, and Redis.
Know when to move fast and when to slow down. Understand that bugs in production have real consequences for real people.
Can get yourself unstuck most of the time and recognize when it's time to ask for help.
Communicate clearly; in code reviews, design discussions, and conversations with non-engineers alike.
Curious and keep learning, especially as AI tools and best practices continue to evolve quickly.

Responsibilities

Design, build, and maintain scalable systems and APIs in Ruby on Rails and React.
Take ownership of systems end to end including reliability, observability, and long-term maintainability.
Use AI coding tools as a core part of how you work, accelerating delivery, prototyping solutions, and writing better code faster.
Bring genuine product thinking to the table: engage in discovery, ask questions about user behavior, and help the team make smart trade-offs between customer value and technical complexity.
Use data and customer research to inform your technical decisions and advocate for the right solutions.
Collaborate closely with Product, and Design; not just during implementation, but during planning and discovery.
Lead system design conversations and contribute to architecture decisions that affect your team's long-term direction.
Write clean, testable, maintainable code and bring that same standard to your code reviews.
Mentor other engineers by sharing context, giving thoughtful feedback, and helping them grow.
