Full Job Description
Avis Budget Group is seeking a Lead Engineer to lead the technical effort for our CRO & Experimentation team - build and QA alike - across Web and App for Avis.com and Budget.com. Reporting to the Director, Global CRO & Experimentation, this role owns getting every experiment built and validated correctly, whether that means doing the work directly or coordinating with whoever else is building it - internal IT, the IT/QA team, or 3rd-party delivery partners. This is a lead role: you're accountable for the outcome even when you're not the one at the keyboard.

You will work closely with CRO Managers, designers, analysts, Product Management, and IT/QA - bringing a test-and-learn mindset and strong technical rigor to everything the team builds.

What You'll Do:
  • Experimentation & Testing
    • Lead the build and QA of A/B and multivariate tests across our regions globally
    • Build experiment variants based on approved designs across web and app
    • Ensure experiments are implemented accurately and tracked correctly from launch, regardless of who executed the work
  • Technical Oversight & Coordination
    • Build both simple front-end variations and more complex, multi-page or personalization-driven experiences
    • Direct and coordinate 3rd-party delivery partners for additional build capacity, ensuring their work meets the same tracking and QA standards as internal builds
    • Coordinate with internal IT resources on more complex technical builds as needed
    • Troubleshoot and resolve technical issues with live experiments
  • QA Leadership
    • Own QA for every experiment - implementing and validating tracking/tagging prior to launch
    • Coordinate with the IT/QA team on regression and cross-site testing, leaning on their broader coverage across the full site
    • Monitor active experiments for conflicts across concurrent tests
  • Cross-Functional Collaboration
    • Work closely with CRO Managers to align on build priorities and timelines, and on tracking and measurement setup
    • Partner with UX and Design to ensure experiments are built to spec
    • Support the handoff of successful tests to Product Management for permanent, production-grade implementation
  • Continuous Improvement
    • Stay up to date with testing platform capabilities, tools, and best practices
    • Proactively suggest process or tooling improvements to increase build efficiency and quality


Perks You'll Get:

  • Access to Medical, Dental, Vision, Life and Disability insurance
  • Eligible to elect other voluntary benefits including: Group Auto Insurance, Group Home Insurance, Pet Insurance, Legal Assistance, Identity Theft Protection, FSA, Accident Insurance, Critical Illness Insurance, and additional life insurance coverages
  • 401(k) Retirement Plan with company matched contributions
  • Full training to learn the business and enhance professional skills
  • Employee discounts, including discounted prices on the purchase of Avis/Budget cars
  • Access to an Employee Assistance Program for services including counseling, financial and legal consultation, referrals for care service and more


What We're Looking For:
  • Hands-on experience building A/B and multivariate tests in Adobe Target, Optimizely, or a comparable web testing platform
  • Working knowledge of HTML, CSS, and JavaScript sufficient to build and troubleshoot front-end experiment variations
  • Familiarity with experimentation across both web and app platforms, or strong aptitude to pick up app-based testing approaches
  • Experience directing or coordinating the work of other engineers or delivery partners, not just executing solo
  • Familiarity with tagging and analytics implementation (e.g., GA4, Adobe Analytics, tag management systems)
  • Highly detail-oriented with a strong QA mindset - comfortable owning QA outcomes even when someone else executes the testing or the build
  • Comfortable coordinating work across internal teams, Product engineering, and external delivery partners
  • Strong organizational skills to manage multiple concurrent experiment builds across regions and platforms


The annual starting salary for this position is between $115,000 - $125,000 annually. Factors that may affect starting pay within this range include geography/market, skills, education, experience, and other qualifications of the successful candidate.
