đź“‹ Description

  • • Ruby Labs is seeking a highly motivated Senior User Acquisition Manager to spearhead and scale paid acquisition efforts across Meta and TikTok for their innovative subscription-based consumer products. This pivotal role is designed for an individual who is passionate about driving measurable growth through performance marketing, with a keen eye for experimentation and a commitment to scalable expansion. You will be instrumental in building, refining, and growing robust acquisition systems, fostering close collaboration with creative, product, and analytics teams to achieve ambitious targets.
  • • In this hands-on position, your day-to-day responsibilities will encompass the full spectrum of paid user acquisition. You will be tasked with owning and scaling campaigns across Meta and TikTok, relentlessly focusing on improving key performance indicators such as Cost Per Acquisition (CPA), Return on Ad Spend (ROAS), and Return on Marketing Investment (ROMI). A significant part of your role will involve identifying successful campaigns and creatives, and then strategically scaling them while meticulously maintaining efficiency and profitability. You will be responsible for constructing and managing campaign structures that are meticulously aligned with overarching scaling objectives, ensuring that every element of the campaign architecture supports growth. Continuous testing and optimization of creatives will be paramount, alongside the execution of structured A/B tests. These tests must be underpinned by clear hypotheses and well-defined learning agendas, ensuring that experimentation leads to actionable insights and tangible improvements.
  • • A core component of this role involves deep data analysis and informed decision-making. You will analyze performance data across the entire user acquisition funnel, from initial ad impression to final conversion and beyond, identifying critical bottlenecks that hinder growth and uncovering hidden opportunities for expansion. Your ability to translate complex data into clear, actionable insights will be crucial for guiding strategic decisions. A thorough understanding of various attribution models and platform-specific nuances, particularly in the evolving landscape of iOS 14+, will be essential for accurate performance evaluation and effective campaign management. Furthermore, you will actively collaborate with creative teams, providing clear, data-driven feedback on ad hooks, angles, and formats to ensure maximum impact. This collaboration extends to helping define and scale repeatable creative frameworks that can be leveraged for sustained campaign success. You will also be tasked with identifying new scaling levers within existing channels, exploring innovative ways to maximize reach and efficiency. This includes testing new audiences, experimenting with novel ad formats, and evaluating different campaign types to uncover untapped potential. When relevant, you will contribute to the strategic exploration and testing of new acquisition channels, broadening the company's marketing reach.
  • • Effective cross-functional collaboration is key to success in this role. You will work closely with product, analytics, and other growth teams to ensure alignment on key performance indicators (KPIs), tracking mechanisms, and reporting standards. Maintaining data accuracy and ensuring proper event tracking are critical responsibilities that underpin all performance analysis and decision-making. This role offers a unique opportunity to significantly impact the growth trajectory of innovative consumer products, gain extensive experience in managing substantial advertising budgets, and develop advanced skills in performance marketing, data analysis, and cross-functional team leadership within a fast-paced, results-oriented environment.
  • • The team at Ruby Labs is driven by a shared ambition to build, grow, and win. They operate with a philosophy of moving fast, aiming high, and expecting the best from their team members. This is a dynamic environment for individuals who are motivated by impact, thrive under pressure, and are eager to embrace challenges as opportunities. If you are hungry to achieve, driven by the desire to make a significant impact, and aspire to grow at the speed of your own ambition, Ruby Labs provides the platform to realize these goals. The company culture values and rewards high effort and exceptional results, creating ample space for individuals who seek more responsibility, accelerated growth, and greater success. This role is an excellent opportunity to contribute to a fast-growing company and to achieve significant personal and professional development.
  • • In this role, you will gain invaluable experience in managing and scaling paid acquisition for subscription-based products, a highly sought-after skill set in the digital marketing landscape. You will hone your analytical abilities by working with complex datasets and advanced attribution models, becoming adept at extracting actionable insights that drive business decisions. The opportunity to collaborate directly with creative and product teams will enhance your understanding of the full marketing funnel and product development lifecycle. Furthermore, you will develop a deep expertise in the nuances of Meta and TikTok advertising platforms, including navigating the complexities of privacy changes like iOS 14+. This position offers a clear path for career advancement within a rapidly expanding tech company, providing the chance to take on increasing responsibility and contribute to high-impact growth strategies.
