Labhouse is a fast-growing startup that builds, launches, and scales its own AI & Productivity Apps, operating under a subscription-based business model. Based in Barcelona, Labhouse was founded by Andrés Bou and Horacio Martos (Co-Founders of SocialPoint). We operate at the intersection of mobile technology, AI, and product-driven growth, with a strong focus on experimentation and performance. Would you like to make an impact as part of a company that builds the best mobile apps used by millions of users worldwide? If so, discover your next challenge below. ABOUT THE ROLE: At Labhouse we're looking to bring onto our Growth team someone who has deep mastery of one acquisition channel and can prove it with real numbers: how much they invested, over what period, and what growth that investment drove. We're not looking for a generalist who "touches a bit of everything." We're looking for specialists — in Apple Search Ads (ASA), Google (Ads Search, Display, Programmatic), Meta, AppLovin, YouTube, Unity, TikTok, UGC, or Influencer Marketing — who have pushed a channel to its maximum performance and can talk about concrete results, not theory. If your strength is one channel and you know it better than anyone, this role is for you. RESPONSIBILITIES: - Manage and scale investment in your channel of expertise, with direct ownership over budget and results. - Define and execute the acquisition strategy for that channel: segmentation, creatives, testing, bid and budget optimization. - Report on performance rigorously (CAC, ROAS, LTV, incrementality) and make data-driven decisions. - Collaborate with Product, Creative, and Data to continuously improve channel performance. - Identify opportunities to expand into adjacent channels when the business needs it, without losing focus on your core area of expertise. ABOUT YOU: Academic background: - Degree in Marketing, Business Administration, Economics, Statistics, or a related field. Equivalent hands-on experience is equally valued. Technical expertise: - Demonstrable experience managing your own budget in one of these channels: Apple Search Ads (ASA), Google Ads Search, Google Display, Programmatic Marketing, Meta, AppLovin, YouTube, Unity Ads, TikTok, UGC, or Influencer Marketing. - Ability to show, with concrete data, how much you invested and what growth that investment produced (figures, timeframes, results — not just "I managed campaigns on X"). - Hands-on experience with the tracking, attribution, and analytics stack tied to your channel (e.g. MMPs, GA4, ad platform dashboards, BI tools). Problem-solving and product focus: - Excellent problem-solving and analytical skills, with the ability to resolve complex technical challenges. - Eye for detail and a product-first mindset, with a passion for creating exceptional user experiences. - Self-driven, entrepreneurial attitude with the ability to work autonomously and take ownership of projects. Communication: - Excelletn level of spoken and written English. - Ability to collaborate effectively with cross-functional teams, including engineering, product, and marketing. NICE TO HAVE: Pluses that are needed occasionally: - Experience in a second acquisition channel beyond your main one. - Background in digital product / apps / e-commerce environments with a growth focus. - Familiarity with creative testing and UGC/influencer content production WHAT WE OFFER: - Remote work from anywhere in Spain. If you are based in Barcelona, we would love for you to join us at the office (Barcelona Tech City) at least two days a week. - Flexible working hours. - High-end equipment for your development. - Permanent contract with competitive compensation. - A young and top entrepreneurial team in a dynamic startup environment. - Opportunity to lead, grow, and take on big challenges. - Work with cutting-edge technologies, including the chance to integrate AI models into new apps.
