• Understanding of forecasting fundamentals (e.g., how LTV/churn/conversion forecasts are built).

Why join:

Hooks & claims: problem → proof → outcome; compliance-safe.
Formats & specs: Reels/Stories/Feed, aspect ratios, first-frame rules.
Copy system: primary text, headlines, CTAs; variations for cold/warm/hot.
Own the schedule: track briefs → production → review → launch; enforce deadlines and QA (creative and tracking).
Run structured experiments (hooks, formats, copy, offers, LPs) and log outcomes.

Optimization & Scale
Diagnose with CPM, CTR, CPC, CVR, CPA/CAC, ROAS/MER, AOV/LTV, payback.
Trigger scale events with guardrails (budget steps, audience breadth, geo expansion, bidding shifts).
Define stop-loss and refresh rules; manage learning phases and ASC/ABO/CBO mix.

Reporting & Communication
Deliver weekly client reports (KPI deltas, creative learnings, funnel insights, 14–30 day plan).
Keep shared dashboards current; flag risks early with mitigation paths; coordinate CRO/retention asks.

Compliance & Brand Safety
Enforce Meta policy, claims substantiation, and FTC/ASA guidance; protect page feedback score.

KPIs You'll Be Measured On
MER/ROAS at/above target while scaling spend
CAC & payback within agreed windows
Creative hit rate (new winners/week) & time-to-winner
Pacing accuracy vs daily/weekly budgets; minimal wasted spend
Report quality & on-time delivery (weekly standard)
On-schedule test execution (brief → asset → launch)

Requirements
4–6+ years hands-on Meta buying with documented profitable scale; comfort managing $200k+/mo portfolios.
Operator mindset with unit-economics fluency (AOV, CM, CAC, LTV, payback) and forecasting.
Attribution chops: CAPI, AEM, GA4/GTM, post-purchase surveys; Triple Whale/Northbeam familiarity a plus.
Proven ability to guide creative strategy from data (briefs, hooks, claims) and to own schedules/QA.
Excellent written/verbal English; crisp stakeholder comms; async discipline (Slack, ClickUp).
Proactive, growth-oriented - you set the plan, align the squad, and own the number.

Nice to have: Shopify/Replo/Webflow CRO familiarity; TikTok/Google experience; multi-country buying.

What We Offer
Performance-based compensation (competitive base + ROI/MER-tied upside).
In-house creative resources with a clear pipeline; testing budgets and fast approvals.
Standardized ops: weekly reporting templates, angle bank, hypothesis tracker.
Fully remote, async-friendly culture; high autonomy, zero micromanagement.

Our Junior Marketing Manager is a key player in analyzing, strategizing, and executing our growth. You won't just be posting; you'll be digging into competitor research, helping build our SEO strategy, and contributing real ideas to our marketing campaigns. We need someone who lives in crypto, understands the culture, and is looking for a place to accelerate their career, take on challenges, and see their results in numbers. If you have a solid foundation in crypto marketing and are hungry to learn and take on more responsibility, this role is for you.

What we offer:

1) Learning and applying your knowledge to real business tasks

2) Work in a team with practical experience and results on the market: we launched our own product with 150,000+ monthly traffic and brought clients to the top

3) Personal growth plan for you to become a marketer who brings results

4) Flexible schedule (office/remote)

5) Salary in USDT at the market level

What you will do: 

• Conduct in-depth competitor and market research to identify new opportunities and strategies
• Participate in brainstorming sessions and contribute to the development and refinement of new marketing strategies
• Assist in keyword research and new website pages development to guide our content strategy and drive organic traffic
• Actively monitor the crypto market and social media for breaking news, emerging narratives, and "alpha" to report key insights to the team.
• Track, analyze, and report on key marketing metrics (ER, CR, Traffic, CTR, etc.), providing insights to the team on campaign performance
• Support other marketing activities as needed (such as email marketing and PR) to gain a broad understanding of the full marketing function.

What we are expecting from you:

• At least 6 months of marketing experience in the crypto/Web3 industry, with a portfolio or examples of your work
• Deep, "crypto-native" understanding of the Web3 ecosystem is a must. You should be familiar with DeFi, L1/L2s, and the airdrop, testnet, and token sale landscape
• A solid understanding of core marketing principles and tactics, including social media, content, and basic SEO concepts
• A proactive, highly curious, and eager-to-learn attitude. You are a self-starter who isn't afraid to ask questions and take ownership of your learning and assigned tasks

• Familiarity with marketing metrics (ER, CTR, etc.) and a desire to learn how to use this data to make strategic decisions
• English Proficiency: B1-B2 (Intermediate to Upper-Intermediate). You must have a strong foundation for reading and writing about complex topics without reliance on AI tools. We support using AI tools to enhance productivity, but a strong, independent grasp of English is essential for your growth.

Nice to Haves:

• Personal, active experience as a crypto community member (e.g., you are an "airdrop hunter" yourself, a community moderator, an ambassador, or a DeFi user).
• Experience of using AI tools for marketing tasks

What you can expect from us:

• Opportunity to learn and acquire practical skills
• Personal growth plan
