Description

A profitable AI music video generator with over $5M in annualized revenue is hiring its first product engineer focused on growth. The hire owns marketing pages, free tools, signup, onboarding, paywalls, and pricing, while also shipping on the core product. The role blends daily production engineering with conversion experiments, programmatic SEO, lifecycle experiments, and growth analytics across PostHog, Google Analytics, and payment data.

Responsibilities

Own and continuously improve marketing pages and site experiences that stay fast, high-converting, and visible in search, Google AI Overviews, and AI assistants
Turn free tools into real product entry points where users keep their song, lyrics, artwork, or progress
Run conversion experiments across the whole funnel: landing pages, calls to action, signup, onboarding, paywalls, packaging, and pricing
Ship on the core product where the growth lever is, especially product-native loops: shareable creations, templates, embeds, referrals, and public pages
Run programmatic SEO experiments without creating low-quality pages, index bloat, or content that exists only for search engines
Build lifecycle experiments tied to real product behavior: activation, abandoned projects, paywall recovery, feature discovery, re-engagement
Make sure conversion tracking is set up correctly
Own growth measurement and data quality across PostHog, Google Search Console, Google Analytics, and backend payment data, building funnels and dashboards you can trust

Requirements

Independently ship production experiences with React, Next.js, and TypeScript, sweating the details that make pages convert: speed, layout, copy, polish
Comfortable moving into backend and data work when necessary, with Python, APIs, SQL, event data, and attribution logic
Think like a marketer as much as an engineer, with real opinions about headlines, page structure, and pricing pages
Think through the complete funnel so visitors activate, pay, and stick around
Understand experimentation: hypothesis, primary metric, guardrails, and a decision threshold defined before the test goes live
Strong product and editorial judgment, building useful experiences for humans rather than generic AI-generated pages
Use AI tools as a genuine extension of how you work, with a high bar for accuracy, originality, and brand quality
High agency: identify the bottleneck, gather evidence, ship a solution, and communicate results without waiting for a perfectly specified ticket
Bonus: personally built something that produced meaningful organic or product-led growth, such as a startup, free tool, or programmatic SEO engine
Bonus: know technical SEO well: crawling, indexing, structured data, internal linking, canonicalization, and safe migrations

Conditions

Full-time employment
VSOPs and profit sharing
Bi-weekly team lunches and regular team events
Annual summer offsite and learning and development support
One-time headphone budget, Deutschlandticket, and productivity tools
EUR 5,000 referral bonus
