Requirements

Dealbreaker

Work Experience:

Must have

Full-stack ownership of features shipping end-to-end PLG features (onboarding, activation, upgrade prompts) that measurably moved a metric.

Hard Skills

Must have

• Proficiency with React, TypeScript, Next.js, and Node.js
• A/B testing and experimentation frameworks

Basline:

Seniority:

Required:

5 - 12 years of experience as a full-stack engineer with hands-on growth work as an IC at an early- or growth-stage startup.

Work Experience

Required:

Ran growth experiments / A-B tests and analyzed funnels (event tracking, SQL/product analytics) to find growth levers.

Hard Skills

Required

AI-native workflow: fluent using AI coding tools (Cursor, Copilot, Claude Code) to ship faster.

Soft Skills

Required

Trusted IC who shapes the growth roadmap and can partner with leadership to ship product.

Nice-to-have

Work Experience

Nice to have

Built internal tooling that growth/product teams adopted.

Traits to Avoid

Avoid

• Pure frontend-only or backend-only specialists
• Growth marketers, SEO or content, lifecycle or CRM, or GTM ops profiles
• Pure research or platform engineers without product instincts
• Treats AI tools as a novelty rather than daily infrastructure

What You'll Do

• Own the growth surfaces end to end: signup, activation, onboarding, and conversion
• Instrument the funnel, run experiments, and ship the changes that move real metrics
• Build full-stack, from the frontend a developer first touches to the backend that powers it
• Treat conversion and activation as your number, you own it, measure it, and move it
• Work close to the data, form hypotheses, test them, and iterate fast on what works.

What We're Looking For

• You're a strong full-stack engineer who's worked on growth or PLG products
• You've personally owned a conversion, activation, or funnel metric, and moved it, not just shipped features someone else measured
• You think like a scientist: hypothesis, experiment, measure, iterate, and you've run real A/B tests you can talk about, including what you learned when they didn't go as planned
• Bonus if you've shipped in-product growth surfaces at a dev-tools or SaaS company (onboarding, activation, upgrade flows, in-product guidance) or built conversion pages that measurably moved signup, not just static pages that shipped
• Bonus for experience with our stack (Next.js, React, Tailwind, TypeScript, Vercel, PostgreSQL, and the Anthropic Claude API) or for having built with LLMs in production: prompt engineering, tool use, inference pipelines
• You've worked on developer-facing products, SDKs, playgrounds, docs surfaces, APIs, and understand how developers actually adopt tools
• You have a track record of staying with your work long enough to see it through (we look for real tenure, not a trail of short stints)
• You move fast and close the loop - you'd rather ship, measure, and iterate than perfect on paper

What We're NOT Looking For

• A growth marketer, this is an engineering role that writes production code
• A backend engineer with no interest in the product surface or the metrics
• Someone who's only ever shipped features without owning an outcome
• A pattern of short stints, we want someone who commits
