Kit is an email-first operating system for creators who mean business. We help creators grow and monetize their audience with ease. For coaches, YouTubers, authors, podcasters, and other creatives, there isn't a better marketing hub to rely on to grow audiences, automate email marketing, and sell digital products — all within one platform.

More importantly, there isn't a team more committed to helping creators earn a living. We're on a mission to help creators earn $1 billion using our creator marketing platform. We have always been 100% independent and 100% remote.

We are proud to have built a product that our customers love, and we look for people who have enthusiasm and belief in our mission, vision, and values to join our team. We're also embracing AI thoughtfully — both in how we build and how we hire to ensure our team is adaptable, innovative, and ready for what's next.

The role

We’re looking for a Senior Software Engineer II to build Kit’s core publishing platform and creator growth experiences.

You will be joining the Builders team, which builds the suite of publishing tools creators use to create emails, landing pages, and newsletters. Our team is responsible for creators' first experiences in the app, from onboarding, to activation, and conversion. And we steward Kit’s core application experience and design system.

You're a frontend expert who thinks full-stack. Modern frontend React development should be your superpower. You're obsessed with crafting exceptional user experiences and have shaped React architectures at scale. But you don't stop at the browser: you architect end-to-end features from database to deployment. You'll help us raise the bar for how creators experience our publishing platform by combining your frontend mastery with full-stack execution.

You combine technical depth with leadership and extreme ownership. You partner closely with Product and Design to shape the “what” as well as the “how.” You thrive in ambiguity, take initiative, and elevate the people around you.

Your support system

You'll report to the Engineering Manager who leads the Builders team, a cross-functional product team at Kit. You'll collaborate closely with a Product Manager, Product Designer, and peer Software Engineers.

You’ll also have access to a group of Engineers across Kit for support and mentorship, and will start with a peer onboarding buddy who will help you navigate our systems and codebase.

What you'll do

As a Senior Software Engineer II, you will:

• First Week: Dive into our codebase and publishing platform architecture. Set up your local environment and merge your first production code. Take part in Get To Know You's to meet our distributed team.

• First Month: Work through your personal onboarding plan. Begin understanding how our publishing tools support creators from onboarding to conversion, and identify opportunities for improvement. Join team activities for planning, building, and measuring the experiences we ship to creators. Actively participate in code reviews, and contribute PRs weekly.

• First Six Months: Lead and architect at least one major feature from ambiguous idea to launch. Transform our legacy codebase through strategic refactoring while applying systems thinking to enhance scalability and maintainability. Drive adoption of patterns and conventions that elevate team-wide technical standards. Ensure service reliability by participating in on-call rotations. Present at least one Lunch & Learn session. Actively mentor peers, and champion quality across our codebase.
