You'll write the code that turns developers discovering the company into developers who can't live without it. This is a full-stack engineering role pointed entirely at growth: you'll own the signup, activation, onboarding, and conversion experience, and you'll be measured on the funnel metrics you move, not just the features you ship. You'll instrument, experiment, build, and iterate on the product surfaces that drive our PLG motion. You'll report to our VP of Revenue and Success and own real conversion outcomes from day one.

• 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

• 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

• 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

We operate at an absurd level of urgency because the window for what we're building won't stay open forever. If you've felt what "scaling chaos" is like at a company growing fast from early revenue to real scale, you'll feel right at home. If that excites you, keep reading. If it doesn't, no hard feelings — but this role probably isn't for you.

Must have:

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

Must have:

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

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.

Required:

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

Required:

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

Required:

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

Nice to have:

Built internal tooling that growth/product teams adopted.
