We’re looking for a Chief Executive Officer (CEO) to take full ownership of one of AIBY’s core product groups — a 20M-install, $10M ARR consumer subscription business — and scale it into its next phase of profitable growth.

Your mission – maximize the Net Profit and Long-Term Value (LTV) of your multi-platform portfolio of apps across iOS, Android, and web by aligning product innovation with data-driven performance marketing.

Unlike a solo founder, you aren’t starting from zero. As a Business Unit CEO, you have:

• immediate access to AIBY’s historical data from 70+ apps to see what works
• centralized Legal, Finance, and HR so you can focus 100% on the product and the users
• significant UA budgets and infrastructure already in place

What you will do:

• P&L Ownership: you’re 100% accountable for the revenue, marketing spend, and operational costs of your unit
• Strategic Roadmap: define the “Why” and the “When”. You decide which features to build based on their projected impact on retention and monetization
• Growth & Monetization: work hand-in-hand with your UA Lead to optimize ROAS (Return on Ad Spend) and Payback Periods. You’ll oversee the subscription funnel, A/B testing, and paywall optimizations
• Cross-Functional Leadership: build, structure, and scale a high-performing team across Product, Growth, Marketing, Engineering, and Design
• Resource/ Capital Allocation Strategy: you have the autonomy to decide where to “bet” your resources. If a specific app in your unit is scaling, you pivot the team’s focus there immediately
• Partnership with the Board and Founders: you’re involved in strategic decision-making at the C-level, with direct impact on business metrics, financial results, and the product ecosystem

What you should have:

• 7+ years of experience in product-based B2C businesses (subscription, mobile/web)
• 3+ years in leadership roles with direct P&L ownership (CPO, CMO, GM, CEO, Product Director, Head of Product, Head of Marketing, etc.)
• Product-Marketing Hybrid expertise: you can speak “Engineering” to the devs and “ROAS” to the marketers. You understand how a product change affects ad performance and vice versa
• Proven 0→1 and scale-stage experience: launching new units, restructuring businesses, scaling early-stage products to meaningful revenue, or founding a startup
• Strong financial acumen: you live in the dashboards. You understand the nuances of cohorts, LTV/CAC ratios, and churn rates in a subscription-based model
• Mentality: ownership, clarity, decisiveness, speed, and persistence
• Entrepreneurial mindset

What we offer:

• Full strategic and operational ownership of a multi-million ARR business unit
• Competitive fixed compensation + performance-based bonus + long-term incentive structure
• The opportunity to scale a category-leading product portfolio into a global market-defining player
• Results-oriented colleagues committed to scaling impactful products. Your team will help you achieve the most ambitious goals

We’re looking for a QA who owns backend quality: payments, subscriptions, and critical flows.
Not a checklist tester. You should understand where things break and catch issues early, ideally before they happen.
 

What you’ll be doing

• Test mobile apps (iOS) and web2app funnels
• Validate checkout flows and payments (end-to-end)
• Test backend APIs (payments, subscriptions, auth)
• Verify core functionality (UI, buttons, user flows)
• Work with webhooks and async processes
• Cover edge cases (failed payments, duplicates, delays, sync issues)
• Analyze logs and debug backend-related issues
• Write test cases and bug reports
• Perform regression testing before releases
• Write automated tests where needed

Requirements

• 4+ years QA experience 
• Mobile (iOS) and/or web testing experience
• Strong experience with payments, checkout flows, subscriptions
• Backend / API testing (Postman, Swagger)
• Experience with:
  • webhooks / async flows
  • logs analysis & debugging
  • payment edge cases
• Understanding of:
  • client-server architecture
  • interaction between frontend, backend, and payments
• Ability to test end-to-end flows (user → payment → access)
• Automation experience (JS / Python / Java)
• Experience with Stripe or similar systems
• Basic SQL, CI/CD, event-driven systems

What we expect

• You think in funnels and user flows, not just screens
• You understand that QA impacts revenue
• You focus on edge cases, not only happy path
• You can work independently, solo and dig into systems
• You take ownership of product quality

What we offer

• Work on a real product with direct impact on revenue
• Ownership of backend and payment systems
• Remote work and flexible schedule
• Fast product iterations without unnecessary bureaucracy
• Strong product team and engineering culture
