Growth Engineer (Full Stack)

OpenArt AI•San Francisco, CA

About The Position

We're looking for a Growth Engineer to be the engineering counterpart to our Growth PM — the person who actually ships the onboarding flows, paywalls, experiments, instrumentation, and lifecycle integrations that move our most important numbers. You'll write production code across our full stack, but your unit of work isn't "tickets" — it's user activation, free-to-paid conversion, retention, and channel-level efficiency. This is a high-leverage moment to join. We grew revenue 7x last year, we're launching OpenArt Director (our new "vibe directing" category), and we're expanding into Brazil, India, and Europe. The growth surface area is enormous and almost none of it has been seriously engineered yet. You'll sit with the Growth PM, the Growth Designer, and our marketing and lifecycle leads — in person, in the Bay Area — and report into the founders. OpenArt is a leading AI Creative Platform for visual storytelling, used by millions worldwide. We're building the next generation of creative tools powered by cutting-edge AI, enabling anyone to create videos, images, visuals, characters, and stories with unprecedented speed and imagination. We believe the future of creativity is AI-native, and we're shaping that future.

Requirements

4+ years of full-stack product engineering at a consumer or pro-sumer company, with at least some of that time embedded with a growth, monetization, or onboarding team
Strong with our stack or close adjacents: TypeScript, Next.js, React, Node, Postgres, running on a major cloud (we're on Google Cloud Platform)
You've shipped paywalls, pricing experiments, onboarding flows, or lifecycle integrations that moved a real number — and you can walk through the implementation choices and what you learned
Comfortable owning a feature end to end: schema, backend, frontend, instrumentation, experiment setup, rollout, and post-launch iteration
Solid instrumentation instincts. You know how to design events that survive contact with a real funnel analysis six months later, and you've worked with tools like Amplitude, Stripe, Meta Pixel, Meta Conversions API (CAPI), and Google Analytics 4 (GA4)
Comfortable in data analysis — you can pull your own numbers and don't wait for someone else to confirm whether your experiment moved the metric
Strong product instincts. You can look at a funnel, talk to a few users, and form your own view on what to build next — and push back when the spec is wrong
Bias to speed. You'd rather ship a clean V1 behind a flag today than a perfect V3 in three weeks
Demonstrate an AI-native approach to daily workflows by effectively leveraging AI tools to improve productivity, creativity, and decision-making.

Nice To Haves

Experience with experimentation platforms (such as LaunchDarkly)
Stripe depth — subscriptions, webhooks, invoicing, customer portal, Adaptive Pricing, and the joys of off-cycle charges
Attribution work — Meta CAPI with deduplication, server-side events, post-purchase surveys, position-bias-aware survey design
Lifecycle tooling — Customer.io , Iterable, Braze, or similar, and the data-pipeline work behind them
Programmatic Search Engine Optimization (SEO) — generating large numbers of high-quality landing pages from structured data, and the headless content management system (CMS) work that goes with it (Strapi or similar)
Internationalization (i18n), regional payment integrations (Pix, UPI, KOMOJU, TapPay, ECPay), and the realities of shipping to non-English markets
Background in consumer AI or generative AI products
Creative tools / design software background (Adobe, Canva, Figma, or adjacent)
You've been an early growth engineering hire before and know how to build the function as you go

Responsibilities

Make onboarding the strongest part of the funnel. Build per-channel onboarding where it matters — different flows for paid, organic, viral, and partnership traffic. Diagnose drop-off, ship variants, and meaningfully lift activation.
Build the paywall and pricing surface area. Paywall design, packaging experiments, plan changes, upsell flows, dunning, regional pricing. Own the engineering side of our free-to-paid engine.
Build the experimentation engine. Set up the infrastructure for well-powered experiments with clean readouts: flag system, assignment, exposure logging, guardrails, and the analysis layer behind it.
Own growth instrumentation. Event schemas, server-side tracking, Stripe webhook flows, Meta CAPI with deduplication, GA4, attribution. The stuff every growth decision depends on.
Ship lifecycle and retention. Email, push, in-app messaging, and resurrection campaigns — the integrations, the triggers, and the experiments inside them.
Power category-defining launches. OpenArt Director, invite-code programs, new market launches — you'll own the growth-side engineering: funnel design, flag rollouts, regional payment methods, and reporting from day one.
Be a great partner to PM, design, and go-to-market. You're in the same room. You give honest feedback on specs, propose alternatives, and own the engineering quality of what ships.
