Job description

Job Description

Aquent is seeking a visionary and hands-on Experimentation Specialist to partner with a leading organization at the forefront of its industry, renowned for operating one of the world’s largest premium platforms. This is a pivotal moment as the organization embarks on a significant brand evolution, and you will be instrumental in shaping the future of user experience. In this role, your expertise will directly impact key business metrics, influence strategic decisions across the entire organization, unlock new insights, optimize user journeys, and accelerate the mission to deliver unparalleled value to a global audience. You will be the architect of insights, translating complex data into clear, actionable recommendations that directly fuel growth initiatives and brand transformation, fostering a data-driven culture of continuous learning and innovation.

About the Role

Are you a seasoned experimentation professional ready to make a monumental impact? We are looking for a dynamic individual to take ownership of our day-to-day testing program. This is an incredible opportunity to build, execute, and refine a robust experimentation framework across diverse channels, including digital advertising, email and lifecycle marketing, landing pages, user onboarding flows, and creative assets. This role is designed for a hands-on operator who thrives in a fast-paced environment. From day one, you’ll dive into our existing testing infrastructure, swiftly auditing current experiments, identifying areas for improvement, and launching more rigorously instrumented tests. You’ll be a central figure in our growth ecosystem, collaborating closely with teams across digital advertising, lifecycle marketing, search engine optimization, creative, data and analytics, product development, and brand strategy.

What You’ll Drive and Own

• Develop and maintain a dynamic testing roadmap and hypothesis backlog spanning digital advertising, email/lifecycle marketing, landing pages, onboarding flows, monetization strategies, and creative assets. You will prioritize experiments using a clear framework, ensuring the highest-impact, highest-confidence initiatives run first.
• Provide weekly, up-to-date views of ongoing tests, key learnings, and upcoming experiments to leadership and channel owners. You will establish and maintain optimal testing velocity, ensuring a steady stream of concurrent, non-interfering experiments.
• Design and launch robust A/B, multivariate, and, where appropriate, holdout and geo-based experiments. This includes meticulous attention to proper control groups, adequate sample sizes, and clearly pre-defined success metrics. You will personally set up and quality assurance tests within various industry-standard experimentation platforms.
• Partner closely with Data & Analytics and Engineering teams to ensure precise tracking, event instrumentation, and attribution prior to every launch. You will define primary, secondary, and crucial guardrail metrics for each test, articulated in plain, business-relevant terms.
• Conduct thorough analysis of test results utilizing analytics platforms, experimentation dashboards, and data warehouse cuts. You will skillfully distinguish between statistical significance and business significance, holding a high bar for both. For every completed test, you will deliver a structured recommendation—whether to ship, iterate, or kill—complete with clear rationale and the next experiment queued for deployment.
• Translate winning results into concrete, channel-specific actions: refining campaign strategies for digital advertising, optimizing flow logic for lifecycle marketing, collaborating with Product for landing page and onboarding updates, and providing creative direction to the Creative team.
• Present complex findings to cross-functional stakeholders through clear, non-technical narratives that effectively connect test outcomes to broader business objectives.
• Connect the dots across all channels, surfacing patterns from digital advertising tests that inform lifecycle messaging and vice versa. You will build shared creative and messaging frameworks derived from comprehensive testing insights.
• Partner with digital advertising, lifecycle marketing, search engine optimization, and content teams to align on learnings, coordinate overlapping tests, and prevent duplicate or conflicting work.
• Maintain a simple, searchable repository of test results to ensure that learnings compound over time, rather than being re-learned. You will champion a robust test-and-learn culture through regular readouts, workshops, and the establishment of clear testing standards.

Must-Have Qualifications

• 2 to 8 years of hands-on experience in conversion rate optimization, growth marketing, experimentation, or analytical marketing, with a preference for experience at a consumer subscription, marketplace, mobile-first, or social platform.
• A practical track record of designing and shipping tests across at least one of the following: digital advertising, email/lifecycle, landing pages, or onboarding, with measurable results you can articulate. Senior candidates will have proven experience across two or more channels, demonstrating measurable business impact.
• In-the-tool fluency with at least one industry-standard experimentation or A/B testing platform, with the ability to set up and quality assurance tests independently.
• A strong working understanding of experimental design principles, including control/treatment setup, sample sizing, statistical significance, and common validity threats (e.g., novelty, seasonality, sample ratio mismatch, interaction effects). You instinctively know when to call a test and when to let it run.
• Robust analytical fluency, comfortable navigating analytics platforms, experimentation dashboards, and spreadsheet tools. You can pull your own data reads and critically evaluate analyses provided by data teams. Senior candidates will be comfortable with SQL or direct data warehouse access to build audiences, validate segments, and conduct independent analysis.
• A proven ability to quickly audit an existing testing program, identify design flaws, and ship a better-instrumented experiment within your first week.
• Exceptional written and verbal communication skills, capable of crafting crisp test briefs and presenting nuanced results to both technical and non-technical audiences with confidence.
• Proficiency with artificial intelligence tools in your daily workflow for tasks such as drafting test plans, generating variant copy and creative, analyzing results, and automating manual processes.
• Demonstrated operator’s discipline: consistently shipping on time, executing with tight quality assurance, maintaining clean naming conventions, and thoroughly documenting every result.
• For senior candidates, ownership of both execution and strategic direction, setting testing standards, driving the roadmap, and confidently defending prioritization decisions to leadership, along with a natural mentorship ability.

Nice-to-Have Qualifications

• Experience within a consumer subscription, marketplace, or social platform environment where activation, retention, and customer lifetime value are primary growth levers.
• Familiarity with advanced statistical methods such as Bayesian methods, multi-armed bandit approaches, or adaptive experimentation, with a clear understanding of their appropriate application.
• A background in behavioral economics or consumer psychology, providing deeper insights into user behavior for sharper hypothesis generation.
• Experience contributing to a company-wide experimentation program, including governance, tooling, standards development, or team training initiatives.
• Experience designing experiments specifically around artificial intelligence-driven personalization or recommendation systems.
• A Bachelor’s degree in Marketing, Business, Statistics, Economics, Mathematics, Computer Science, or a related analytical field, or an equivalent track record of shipping rigorous tests.
