The role
Kit is forming a dedicated Product Growth team for the first time, and we need an Senior Software Engineer II who can help us figure out how to grow. 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, and collaborate closely with our Senior Product Managers, 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.
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.
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 ability to work independently while collaborating closely with teammates.
You work in public to share progress, post results (even disappointing ones), and document decisions clearly enough that others can build on your work.
You're analytical. You want to measure what you ship, but you also know when enough data exists to make a call and when over-indexing on analysis is just delay with extra steps.
You believe that creator success is our success, always thinking about what it means for a creator to get value from Kit through growth and monetization.
You're comfortable in early-stage team conditions. The growth team is new and the playbook isn't written yet. You're energized by that, not unsettled by it.
You have a strong interest in AI and an eagerness to experiment to make our work more efficient and effective.
What won't set you up for success
Preferring to work from a detailed spec rather than helping shape what gets built and why.
Discomfort with ambiguity and lack of structure
Optimizing for shipping over learning; if you don't care what the experiment result was, this probably isn't the right fit.
Wanting extensive approval loops before moving. We trust people to make calls, share their thinking, and move quickly
A strong preference for deep specialization. You won’t be doing feature engineering; you’ll be experimenting across the full product-led journey, acquisition through expansion.
