• Build customer-facing features, internal tools, and standalone prototypes/MVPs
• Execute A/B tests, feature flag deployments, and landing page experiments
• Instrument tracking and analytics to measure experiment outcomes
• Analyze experiment results and provide data-driven recommendations (scale, iterate, or terminate)

Technical Development

• Write and deploy production code for web applications using existing tech stack (Vercel, Post Hog, Loops, N8N)
• Utilize AI-powered development tools to accelerate build cycles
• Collaborate with full-stack developers to integrate validated experiments into core product
• Maintain version control practices (Git) and follow deployment workflows
• Build feedback mechanisms to gather user insights and inform future experiments

Performance Measurement & Reporting

• Track key growth metrics and experiment performance using Post Hog analytics platforms
• Report experiment outcomes to wider Tech team with clear next steps
• Maintain documentation of experiments, learnings, and technical implementations
• Identify and prioritize new growth opportunities based on data analysis
• Work cross-functionally with developers, designers, and marketing team members
• Communicate technical decisions and experiment results to non-technical stakeholders
• Participate in rapid priority shifts based on business needs and data insights
