10arx HR
Marketing Manager in 10 arx
Full time
Remote
Your north star metric is one thing: active traders on the platform generating volume. Not followers. Not Discord members. Not impressions. Traders who deposit and trade.
About 10arx
10arx is an AI-native trading terminal for prediction markets. We aggregate Polymarket, Kalshi, and other exchanges into one professional-grade interface - smart market discovery, AI analytics, agentic automation, advanced execution, and a fully customizable dashboard.
We are building for serious traders - people who trade systematically and want a real edge. This is not a product for casual users. The technical team is in place. Now we are building product and growth.
The role
You are the first person responsible for all of growth. There are no existing processes. No team that already figured it out. You build everything from zero - strategy, channels, agency management, influencer partnerships, and the team itself.
This is not a support role. This is not a social media manager role. You own the entire growth function with full accountability.
What you will own
Go-to-market strategy. Build the full pre-launch and launch plan. Own the budget, justify every line of spend, and report results. Structure and accountability - not guesswork and vibes.
Influencer and KOL partnerships. Identify the right people in the prediction markets and crypto trading community. Build real long-term relationships - not one-off paid posts. We want people who actually trade on platforms like ours and talk about it authentically.
Agency management. Set briefs, control results, don't let agencies run in "report-for-show" mode. Know what you are paying for and defend every decision to the founder in two sentences.
Hiring and building the marketing team. Close the SMM role yourself - write the JD, run interviews, onboard, and build a working system. You define how the team operates.
Community and content. Own the brand voice across Twitter/X, Telegram, and Discord. Build a genuine community around prediction markets - not just manage accounts. In the early days you post yourself, daily. You engage. You make 10arx impossible to ignore in the prediction markets space.
Pre-launch activation. Build the waitlist, create pre-launch momentum, and get the first 1K traders into the product before public release. The core audience needs to exist from day one.
AI-powered marketing systems. Build and run AI agent workflows for growth: automated prospect research, influencer pipeline tracking, content generation pipelines, performance monitoring. If something can be delegated to an AI agent - it should be. This is a core part of the role, not a bonus.
Analytics and retention. Track CAC, funnel conversion, influencer ROI. Own email and Telegram retention flows. Traders leave fast if they don't see value - keeping them is your job too.
Partnerships and BD. Build integrations and co-marketing with projects in the Polymarket and prediction markets ecosystem. Access to existing audiences - not ads.
What we are looking for
You actively trade or closely follow prediction markets and know the trading community from the inside - Polymarket, Kalshi, or similar
You have built or grown a crypto Twitter/X account or Telegram community with measurable results you can show us - not just assisted, but owned it
You have real experience with crypto, Web3, or fintech influencers - not just sending pitches, but building real long-term relationships or a proven method for doing it fast
You have managed or allocated a marketing budget before and can defend every line of spend with data
You have managed agencies: you know what to ask, how to measure results, and where they tend to waste money
You have built a marketing function or team from zero - and you can do it again
You think in systems: you see the full funnel, not individual posts and campaigns
You actively use AI tools - you automate research, build agent workflows, and delegate routine systematically
You can work independently without being managed - we are a small founding team and you will own this function completely
You are proactive, fast, and comfortable operating in a space that moves every hour
Nice to have
You trade on Polymarket or other prediction markets yourself
You have an existing network of crypto traders, KOLs, or analysts
You have launched products in Web3 or fintech from zero
You understand the Polymarket Builders program and builder rewards mechanics
You have grown an audience of serious traders - not mass retail
You have hands-on experience building AI agent pipelines for marketing or growth
Not a fit if
You don't know what a prediction market is and have never traded - this is not a space where you can figure it out later
Your entire influencer experience is e-commerce or lifestyle - crypto and trading audiences work completely differently
You are used to receiving briefs and executing - here you create the strategy yourself
Your growth metrics are follower counts and impressions - we care about traders in the product, not numbers in a report
You think AI tools are for writing captions - we expect full agent workflows, not prompts in ChatGPT
What we offer
Competitive compensation based on experience - discussed individually
Performance bonuses tied directly to active trader growth and platform volume milestones
Full ownership of the growth function from day one - no bureaucracy, no approvals chain
Small founding team, direct line to the founder, decisions made fast
You are building in a market that is genuinely growing
