We are dedicated to creating and operating cutting-edge products across the health, education, and entertainment industries, shaping the future of consumer-led experiences. Our culture is built on passion, ambition, and a relentless drive for growth, and we are seeking a highly experienced Senior Data Analyst to become an integral part of our rapidly expanding team.
  • • In this pivotal role, you will be instrumental in shaping our data-driven decision-making processes. Your primary focus will be on the meticulous creation of new reports and the continuous enhancement of existing ones, ensuring the accuracy, integrity, and optimal modeling of our data assets. You will collaborate closely with a diverse range of stakeholders, including Product Owners and internal Data Teams, to architect and build robust data environments that empower informed strategic choices.
  • • A key aspect of your responsibility will involve in-depth user behavior analysis, including the critical "aha moment" analysis, to understand user engagement and identify key drivers of product adoption and retention. You will dive deep into complex datasets to uncover actionable insights, identify emerging trends, and detect subtle patterns that can be leveraged to maximize key performance indicators (KPIs).
  • • Your analytical prowess will be crucial in monitoring essential business metrics, providing timely updates, and proactively identifying areas for improvement or potential risks. You will be responsible for designing and constructing sophisticated, well-modeled data structures using advanced SQL, ensuring scalability and efficiency for future analytical needs.
  • • This role demands a proactive and collaborative approach. You will be expected to provide and receive constructive, actionable feedback from your peers and the Leadership Team, fostering a culture of continuous learning and improvement. Your ability to translate complex data findings into clear, concise, and compelling narratives will be essential for influencing product strategy and business direction.
  • • You will play a critical role in defining and refining product analytics strategies, working closely with Product Owners to understand their needs and translate them into data requirements. This includes setting up and interpreting experiments, analyzing A/B test results, and providing recommendations for product enhancements based on user data.
  • • The ideal candidate will possess a strong understanding of the subscription business model, enabling them to analyze churn, retention, and lifetime value metrics effectively. You will contribute to strategic discussions around customer acquisition, engagement, and monetization, using data to validate hypotheses and guide strategy.
  • • Beyond technical skills, you will demonstrate a strategic mindset, capable of thinking critically about business objectives and aligning data analysis efforts to achieve them. Your ability to adapt quickly to new tools, methodologies, and evolving business needs in a high-pressure, fast-changing environment will be paramount to your success.
  • • This is an opportunity to make a significant impact within a fast-growing company, contributing directly to the success of innovative consumer products. You will be empowered to take ownership of your work, drive initiatives, and grow your career at the speed of your ambition, supported by a team that values high performance and rewards results.
