• Manage and mentor a multidisciplinary growth team across paid UA, CRM and more
• Build and optimize reporting systems for daily/weekly visibility across paid marketing, CRM, funnel performance, and product usage
• Collaborate with product, brand, and central growth teams to align roadmaps with local market opportunities
• Contribute to Korea's brand positioning and comms strategy in service of broader market growth

What We're Looking For

• Proven growth leadership : 7+ years in high-growth tech or consumer startups, with ownership of $10M+ annual marketing budgets across both web and app
• Full-stack growth expertise : Deep hands-on experience in performance marketing, funnel optimization, and experimentation
• Builder mentality : Comfortable building systems, dashboards, and processes from scratch—while operating at both strategic and executional levels
• Strong operator : Ability to synthesize performance signals and drive cross-functional execution across marketing, product, and brand
• Team leader & coach : Track record of building, mentoring, and managing high-performing growth and marketing teams
• Local fluency, global mindset : Deep understanding of Korean consumer behavior with the ability to adapt and apply global best practices

Why Work at Speak

1. Join a fantastic, tight-knit team at the right time: we're growing very quickly, we've most recently raised our Series C from some of the top investors in the valley, and we've achieved product-market fit in our initial markets. You'd join at a magical time when a single person could significantly change the course of the company.
2. Do your life's work with people you'll love working with: we care strongly about our craft and want every person at Speak to feel like they're growing every day. We believe in the idea that working with people you both enjoy and have respect for makes everything better. We hire thoughtfully and only work with people we admire deeply.
3. Global in nature: We're live in over 40 countries and launching in a number of new markets soon. We have dedicated offices in San Francisco, Ljubljana, Seoul, and Tokyo, and you'll have the opportunity to talk to users in each of these regions on a regular basis as well as travel.
4. Impact people's lives in a major way: Learning a language is one of the single most life-changing skills one can learn, and right now 99% of people never achieve their goal because the process is broken. We're helping millions of people achieve their goals and improve their lives.
