  • Deep experience with A/B testing, feature flagging, and user cohorting tools and methodologies

  • Strong programming skills in modern web technologies (e.g., JavaScript/TypeScript, React, Python, or Node.js) and cloud infrastructure (AWS/GCP); hands-on ability to guide architectural decisions

  • Experience working cross-functionally with Marketing, Product, Design, and Data Science teams

  • Deep understanding of conversion rate optimization (CRO), SEO, and performance engineering

  • Passion for rapid iteration, experimentation, and growth-driven development

  • Excellent leadership, communication, collaboration, and stakeholder management skills

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
