Job description

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 Kit culture is one where emotional intelligence is valued, radical candor is encouraged, and where everyone works together to uphold a set of shared team principles.

The deadline to apply is 11:59 PM Pacific Time on Monday, June 9th.

This is a hands-on role for a product-minded engineer who thrives collaborating with Product and Design to craft beautiful and impactful user experiences. You’re a technical leader who can architect extensible systems end-to-end across the stack, with particular strength on the frontend.

• 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. 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.
