Lead Data Analyst, Growth – Experimentation

This is a fully remote position, open to applicants in Brazil.

📋 Description

• Take ownership of the experimentation program across web funnels, SMS/drip communications, sales-driven tests, and SEO evaluations.

• Design experiments, determine power and sample sizes, set significance and readout standards, and identify underpowered tests and false positives.

• Expand Growth tests into continuous monitoring and ensure early decisions adhere to crossed statistical boundaries.

• Develop and maintain the self-service experimentation layer, incorporating automated Growth metrics in Lightdash, Python-supported statistical-significance tools, and AI capabilities for pre-test power assessments and live-test health evaluations.

• Create and sustain a reliable, instrumented acquisition-to-conversion funnel from visitor to lead to customer across all brands and channels.

• Provide analyses for CAC, LTV, and conversion rates to inform Growth investment prioritization.

• Establish the standards and playbook for the Growth analytics function by the end of Year 1.

• Recommend whether to buy or build the experimentation stack.

• Collaborate directly with the Director of CRO, performance marketing, and Growth PMs.

• Deliver insights that influence decisions, challenge misconceptions, and quantify conversion improvements.

• Operate as an individual contributor without responsibilities for managing people.

⛳️ Requirements

• Regular use of AI for SQL, dbt, and analysis pressure-testing; eagerness to enhance existing AI experimentation skills.

• Strong expertise in statistics related to experiment design, power, significance, novelty effects, interaction effects, and the appropriateness of testing.

• Ability to communicate broken experiments and statistical concepts in straightforward language.

• Experience with Segment events and Flagsmith randomization, including experiment instrumentation and tracking validation.

• Knowledge of CAC, LTV, channel economics, attribution challenges, seasonality, and channel mix.

• Proficient SQL skills.

• Sufficient Python skills to automate statistical-significance calculations.

• Familiarity with dbt and Lightdash.

• Capability to independently build data models without relying on data engineering.

• Ability to influence PMs and marketers without formal authority.

• Capacity to work with US-facing partners and manage overlapping hours.

• Eligibility as a Brazil-based independent contractor.

🏝️ Benefits

• Contractor engagement: Arrangement as a Brazil-based independent contractor, standard for our Brazil-based team. No equity offered.

• The scope is the attraction: Be the first analyst exclusively dedicated to Growth and Experimentation, leaving your mark on the company’s decision-making processes.

• AI tools provided: Utilize the Claude routines already integrated into our experimentation workflow, which you are encouraged to expand, rather than treating it as a side project.

• Fully remote (Brazil): Engage in deep-focus analytical work with US-facing partners. We prioritize hiring the best analyst regardless of their location, trusting you to manage your workspace and overlapping hours effectively.

• Flexible PTO: Evaluated based on outcomes rather than hours logged.
