Senior Growth Marketing Lead

Ostium is on a mission to revolutionize trading by providing a transparent, permissionless trading stack built onchain. The Senior Growth Marketing Lead will own user acquisition, identify new growth channels, and execute marketing experiments to drive user engagement and retention.

Responsibilities:

• Net new user acquisition. Own the top of the funnel, including traffic, signups, funded accounts, and first trades
• Channel discovery and arbitrage. Identify, test, and scale acquisition channels we aren't running today, including SEO, lifecycle email, paid social, TikTok, YouTube creators and finance influencers, Reddit, Telegram communities, podcast sponsorships, referral and affiliate programs, retargeting, regional channels in LATAM, SEA, and MENA, and any asymmetric growth opportunities you discover
• Influencer and creator strategy. Build a trader-focused creator program. Source, negotiate with, brief, and measure YouTube, TikTok, and Instagram creators whose audiences resemble our next cohort of traders
• SEO and content. Build our SEO program from scratch, including keyword strategy, programmatic pages, comparison and "vs." content, educational hubs, and link building. Partner with content writers and engineers to execute
• Lifecycle marketing. Own the email, push notification, and in-app user journey from waitlist to first deposit through long-term retention, including segmentation, automated triggers, win-back campaigns, and deposit flows
• Paid acquisition. Launch and optimize paid acquisition channels where regulation and CAC allow, including programmatic, paid social, search, and native advertising. Quickly shut down what doesn't work
• Funnel analytics. Define growth metrics, build dashboards, and drive a rigorous experimentation cadence. Track CAC by channel, funded account conversion, LTV, and payback period

Requirements:

• 2+ years of experience in growth or performance marketing, ideally within crypto, consumer fintech, or trading platforms
• Deep expertise in at least two growth channels. For example, you've successfully scaled paid search or paid social campaigns, or built a UGC program from scratch
• A true zero-to-one operator. You've built a growth function from the ground up by selecting channels, implementing tools, running experiments, and delivering measurable results
• High agency with full ownership. You don't wait for direction. You identify opportunities and are excited to execute experiments yourself
• Highly analytical and comfortable using tools such as GA4, Amplitude, Mixpanel, and attribution platforms
• A strong writer who can create ad copy, landing pages, creator briefs, and email campaigns without relying on a copywriter
• Both an operator and a builder, capable of executing independently today while growing a team over time
• Crypto native or an active trader. You either actively trade on traditional or crypto platforms, or you deeply understand crypto culture and are excited to immerse yourself in the perpetual DEX and onchain trading ecosystem
• Experience growing products in regulated or semi-regulated industries where paid acquisition is constrained, such as crypto, iGaming, CFDs, or similar markets
• Experience building affiliate or introducing broker (IB) programs
• Active participation in Telegram trading communities with an established network
• Experience scaling modern distribution tactics such as clipping, TikTok, or YouTube creator programs
• Hands-on experience with attribution platforms and AI tools for marketing and growth
• You are an active trader yourself

You understand how traders are acquired and what motivates them to fund their accounts
