Senior Software Engineer II - Product Growth

About the role

The Kit Product Growth team is seeking 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.

Responsibilities

• Own the end-to-end execution of multiple growth initiatives across the funnel.
• Identify the highest-leverage bets, scope them with the team, build them, measure the outcome, and share what you learned.
• Ship improvements across more than one part of the funnel, not just the part that was assigned to you.
• Think like a product person, bringing 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.
• Work in public to share progress, post results (even disappointing ones), and document decisions clearly enough that others can build on your work.

Requirements

• Full-stack engineering experience on product-led initiatives at a SaaS company.
• Experience working on a product where the customer relationship involves recurring revenue, trials, or conversion milestones.
• Experience leading experiments end-to-end and speaking to what you learned, including the ones that didn't work and why.
• Experience shipping improvements across more than one part of the funnel, not just the part that was assigned to you.
• Experience working on a remote-first or distributed team with minimal process overhead.

Qualifications

• Comfortable with legacy systems and context-switching between fast experimentation and slower, more deliberate technical work.
• Strong interest in AI and eagerness to experiment to make our work more efficient and effective.

Skills

• Full-stack engineering, primarily Ruby on Rails and React.
• Data-informed decision-making, including familiarity with SQL and analytics tooling like Omni and Mixpanel.
• Funnel thinking, understanding acquisition, activation, retention, and monetization as a system.
• Building reusable infrastructure, considering how something can accelerate the next thing.

What will SET you up for success

• Thinking like a product person, bringing 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.
• Having high agency and ability to work independently while collaborating closely with teammates.
• Working in public to share progress, post results (even disappointing ones), and document decisions clearly enough that others can build on your work.
• Being analytical, wanting to measure what you ship, but knowing when enough data exists to make a call and when over-indexing on analysis is just delay with extra steps.
• Believing that creator success is our success, always thinking about what it means for a creator to get value from Kit through growth and monetization.
• Being comfortable in early-stage team conditions, energized by that, not unsettled by it.
• Having 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.
• Wanting extensive approval loops before moving.
