Kast is hiring a

Web3 Marketing Copywriter

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 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.

• 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.

• 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.

• 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.

We hire through referrals, networks, and a proven ability to execute.
