Job description
- Implement A/B testing frameworks and feature flags
- Build systems that allow rapid UI and copy variation
- Ensure statistical validity and clean experiment instrumentation
- Maintain experiment guardrails to prevent revenue cannibalization
- Reduce load times and improve Core Web Vitals
- Optimize API response times under traffic spikes
- Introduce caching strategies (Redis/CDN/edge-aware logic)
- Ensure mobile-first responsiveness and SEO integrity
- Implement pricing experiments and upsell triggers
- Build event-driven communication triggers
- Integrate payment systems (Stripe or similar)
- Design eligibility logic for subscription offers
We aim for 80-90% AI-assisted development.
You will:
- Maintain and improve CLAUDE.md / AGENTS.md documentation
- Write test-first specifications for AI agents
- Review AI-generated PRs for architectural integrity
- Improve module boundaries for AI legibility
- Use AI to accelerate experimentation - not replace thinking
Your leverage comes from system design and review - not typing speed.
Requirements
- 5+ years in frontend-driven fullstack product environments
- Backend experience (Node.js, Symfony, or equivalent)
- Experience building conversion funnels or subscription flows
- Strong understanding of analytics instrumentation (GA4, Amplitude, Segment, Mixpanel)

- Comfortable working with AI coding tools (Cursor, Claude Code, Copilot, etc.)
- Fluent English and comfortable in distributed teams
- Experience in freemium or subscription-based products
- Experience in high-traffic consumer platforms
- Experience with SEO-sensitive landing page systems
- Familiarity with Redis / caching strategies
- Experience with CI/CD (GitLab or GitHub Actions)
- Exposure to growth experimentation culture
- Your ability to quantify impact (conversion, retention, revenue)
- Your system thinking, not just UI implementation
- Your comfort with AI-assisted workflows
- Your ability to balance experimentation speed with maintainability
Benefits & conditions
- Clean, maintainable funnel architecture
- Clear ownership of funnel KPIs
- Small autonomous squad
- Direct collaboration with product, marketing, and analytics
- Outcome > output
- High experimentation tolerance
- AI as force multiplier, not shortcut
Why Join the Acquisition Squad?
