Join a part-time contract design role focused on evaluating and scoring design treatments for growth and experimentation work. This opportunity is ideal for someone with direct experience on growth teams who has helped run or analyze A/B tests and can bring a thoughtful, metrics-driven perspective to incremental product optimization.

Responsibilities

• Review and grade design treatments with a focus on incremental growth and experimentation outcomes
• Evaluate creative variations against defined criteria and surface clear, consistent judgments
• Assess experiments using real performance metrics and observed results
• Work on repetitive review tasks with accuracy, consistency, and attention to detail
• Contribute practical feedback grounded in hands-on growth or experimentation experience
• Communicate your availability, time zone, and contracting status clearly during the screening process

Skills

• Direct experience on a growth or experimentation team
• Hands-on involvement in running or analyzing A/B tests
• Ability to describe experiments with specific metrics, results, and learnings
• Strong understanding of incremental optimization and iterative product design
• Comfort working on repetitive evaluation tasks at a steady pace
• Clear, honest communication about work style, experience, and availability
• Ability to contract with a U.S.-based company

Preferred Skills

• Background in product design, especially within growth-focused product surfaces
• Experience with experimentation principles and what makes a treatment effective
• Ability to articulate core principles of strong incremental growth product design
• Examples of both successful and unsuccessful experiments, with thoughtful takeaways
• Portfolio or work samples that support relevant experience
• Availability for part-time contract work and flexibility to align with project needs
