Marketing Lead, KAST Business

Department: Growth

Employment Type: Full Time

Location: New York

Description

KAST is redefining stablecoin banking for global citizens, crypto professionals, Web3-native businesses, and high-inflation markets that want USD-backed banking. Backed by top-tier global investors and led by the former APAC CEO of Circle, our leadership team spans Circle, Airwallex, Revolut, Wise, Grab, Zoom, AWS, and leading OTC desks. We scaled from zero to nearly a million users at speed.

One account lets a business hold USD and stablecoins, spend on cards worldwide, and pay contractors and vendors in 170+ countries over local rails, SWIFT, SEPA, and stablecoins. Businesses incorporated in the US, UK, UAE, Brazil, and Australia onboard under one program.

We came out of beta in August. Monthly card volume is up more than 10x since then, and hundreds of active businesses run on KAST Business today. Our fastest-growing customers are performance marketers: agencies, media buyers, and e-commerce brands funding ad spend across Meta, Google, and TikTok.

About the role

KAST Business is hiring its first marketing lead. You will be a generalist who builds the function from the first campaign forward. You will run events, write the product marketing that sales and customers rely on, support top-of-funnel demand, and take on whatever else the business needs to grow. You report to the US General Manager and work every day with Sales, Product, Compliance, and Operations.

Key Responsibilities

Plan and run events across the year. Own booth strategy, speaking submissions, side events, and post-event follow-up with sales.
Write and maintain product positioning, one-pagers, sales decks, competitive comparisons, and objection handling.
Support top-of-funnel demand: website copy, landing pages, email and LinkedIn programs, webinars, and content for media buyers, agency owners, and finance leads.
Build the case study pipeline. Interview customers, write their stories, and turn them into assets sales can use.
Run launches. Coordinate feature announcements, release notes, and customer messaging with Product.
Set up the marketing stack and measure results. Own tracking, attribution, and a weekly report on pipeline sourced by channel.
Turn sales and customer feedback into messages that Product and leadership act on each week.
Build the function as it grows. Write the first playbooks, manage vendors, and make the case for every dollar spent.

Skills, Knowledge and Expertise

3 to 6 years in marketing at an early-stage startup, a fintech or payments company, or an agency.
Product marketing experience. You have written positioning, sales decks, or launch materials that sales teams used every week.
Event experience, including booth execution, sponsorships, and partner programs.
Working knowledge of performance marketing. You understand how media buyers run campaigns across Meta, Google, and TikTok.
Payments fundamentals: cards, FX, cross-border payouts, and stablecoins. You explain them in plain language.
Strong writing. You write clear copy for founders, finance leads, and operators.
Scrappy execution. You ship a campaign in a week, measure it, and change course.
Comfort with ambiguity. You build the first version of each program and keep the work moving.
Data sense. You build dashboards in a CRM and spreadsheets and read them without help.
Coachability. You take direct feedback and apply it on the next project.

Nice to have:

Experience as the first marketer or an early team member at a startup.
Experience marketing to media buyers, agencies, or e-commerce brands.
Hands-on crypto experience: wallets, exchanges, or on-chain payments.
Portuguese or Spanish fluency.
A network in the events circuit or in performance marketing communities.
