Marketing Copywriter

Job Description

About KAST KAST is redefining what it means to bank with stablecoins - think Revolut, rebuilt from scratch on Web3. Backed by top-tier VCs, we’ve grown from 0 to 1 million users in under a year. We’re building the next-gen global bank based entirely on stablecoins. Design is at the heart of everything we do - it’s how we simplify the complex, make money feel easy, and turn crypto skeptics into brand ambassadors. KAST is a fast-growing force in the financial technology and startup landscape. We are building the future of financial services with a focus on innovation and speed. Our culture thrives on bridging product excellence with aggressive growth, and we are looking for a key player to join our mission-driven team. The Role The Marketing Copywriter will own voice and narrative across growth surfaces—landing pages, paid ads, lifecycle (email/push/in-app), and product UI. You’ll turn complex fintech/Web3 ideas into crisp, high-converting copy that performs in Brazil, MENA, and beyond. What You’ll Be Doing Conversion Copy: Ship A/B-tested copy for landing pages, ad creatives, app store, and paywalls that move CTR, CVR, and CPA in the right direction. Lifecycle + CRM: Partner with Growth to write Braze campaigns (onboarding, KYC, deposit, first spend, referral). Product/UI Microcopy: Craft tooltips, error states, and empty states that reduce confusion and drop-off. Messaging Frameworks: Build positioning, value props, and tone guidelines for country launches (e.g., PIX Brazil). Compliance Friendly: Write clearly within fintech/legal guardrails without sounding like a robot. What You'll Bring 3–6 years in copy for fintech/consumer tech or performance-driven brands. Proven portfolio with measurable lift (CTR/CVR/LTV). Fluency in A/B testing and using data (GA4, Mixpanel, AppsFlyer) to iterate. Excellent short-form chops; long-form range a plus. Preferred Crypto/Web3 exposure; understands stablecoins and on/off-ramp basics. Why KAST? Build and own KAST’s community presence in your city from the ground up. Host events, connect founders and VCs, and shape how our brand lives locally. High autonomy, creative freedom, and the chance to directly influence our global growth. Join a no-BS, high-energy team on track to be the next unicorn. How To Apply? We hire through referrals, networks, and a proven ability to execute.
