Senior Software Engineer II - Product Growth

About this role

Kit https://kit.com/ 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

Kit recently formed a dedicated Product Growth team, and we need a Senior Software Engineer II to build the in-product experiences that connect creator needs to realized value, increasing the number of creators who succeed through the product while driving Kit's growth. We're looking for a Senior Software Engineer II to own the technical execution of high-leverage improvements across the full funnel: acquisition, activation, retention, and monetization.

This is a full-time IC role best suited for someone who loves being close to the business, cares about measuring and iterating on what they ship, and combines technical knowledge with leadership and extreme ownership. This is a newly formed team that’s still taking shape, so there isn’t a fully built-out structure yet. You’ll have a high degree of autonomy, with the opportunity to step in, identify what needs to be done, and drive work forward.

YOUR SUPPORT SYSTEM

You'll report to Megan Mullin https://www.linkedin.com/in/megan-talbot/, and collaborate closely with two engineers, our Senior Product Manager, product designers on different squads, and a data analyst on the growth team. You'll also work cross-functionally with engineers across Kit's product squads, tapping into shared infrastructure, coordinating on funnel-adjacent work, and contributing back to the broader engineering community.

This is a newly formed team, so you'll have real influence over how it takes shape.

WHAT YOU'LL DO

- First Week: Get oriented in our onboarding curriculum in Notion and get access to key tools — Linear, Figma, Slack, Looker, Omni and our experimentation infrastructure. Start meeting your teammates and cross-functional partners through GTKYs. Get a feel for our codebase, our current funnel metrics, and where the biggest opportunities live.

- First Month: Dig into the data and current growth opportunities. Understand where creators are dropping off and why, and you have a clear point of view on what's driving disengagement and where the highest-leverage retention opportunities are. Start contributing to active experiments or funnel improvements while you build context. Ship your first changes, to get a real feel for how we move and contribute to our growth strategy. You'll also start getting familiar with our billing domain — a large, legacy codebase that the growth team now owns.

- First Six Months: Own the end-to-end execution of multiple growth initiatives across the funnel. You're not waiting for a spec, you're helping identify the highest-leverage bets, scoping them with the team, building them, measuring the outcome, and sharing what you learned. You've shipped experiments and owned complex projects that moved meaningful metrics and can speak clearly to what worked and what didn't.

- First Year: You've established the technical patterns and measurement practices the growth team relies on. You’re a leader on the Growth squad and a strong, trusted partner to Product. You have a clear point of view on what the funnel needs, and you're coaching others toward more analytical, outcome-driven ways of working. You're a core reason the team ships with both speed and confidence.

WHAT WILL S.E.T. YOU UP FOR SUCCESS

Skills

- Full-stack engineering. Our stack is primarily Ruby on Rails and React, and you are ideally comfortable with both.

- Product judgment. You think about the experience, not just the implementation. You have opinions about what's worth building and collaborate with product and design.

- Data-informed decision-making. You're comfortable in SQL, know your way around analytics tooling like Omni and Mixpanel, and can connect product metrics to business outcomes.

- Funnel thinking. You understand acquisition, activation, retention, and monetization as a system, not a checklist. You can identify where the real leverage is, and where it isn't.

- Building reusable infrastructure. You think beyond the immediate experiment. When you build something, you consider whether it can accelerate the next thing too.

- Comfort with legacy systems. We own a complex billing domain, you don't need to be a billing expert, but you should be someone who isn't intimidated by large legacy codebases and can context-switch between fast experimentation and slower, more deliberate technical work.

Experiences

- Software engineering experience on product-led initiatives at a SaaS company

- Worked on a product where the customer relationship involves recurring revenue, trials, or conversion milestones

- Led experiments end-to-end, and can speak to what you learned, including the ones that didn't work and why

- Shipped improvements across more than one part of the funnel, not just the part that was assigned to you

- Worked on a remote-first or distributed team with minimal process overhead 

Traits

- You think like a product person. You bring your own point of view on what the funnel needs, what the experiment should test, and whether the proposed solution is actually the right one.

- You have high agency and abil
