Yanarchy is a Los Angeles–based talent agency that partners with unique, driven talents, helping them reach new heights and fulfill their dreams. We focus on cultivating individuality and providing full support so our talents can maximize their potential and achieve their goals. Yanarchy is not just an agency — we are building a future ecosystem of services and monetization tools, developed as independent projects based on our expertise.

Mission

Build, manage, and scale a resilient, high-volume organic lead-generation infrastructure that serves as the primary high-margin revenue driver for the company’s talent portfolio, ensuring total operational control over traffic velocity and asset security.

Goal

Maximise the company’s profitability and revenue growth by engineering, managing, and scaling a high-volume, resilient organic traffic ecosystem that systematically converts media presence into immediate, predictable monetization.

Direct ROI & Revenue Generation: Turn organic distribution into the primary, high-margin revenue driver for the company’s talent portfolio, shifting from chaotic views to predictable cash flow.

Infrastructure-Backed Profitability: Build and operationalize a high-output distribution department from scratch, establishing scalable workflows (automated uniqueization, mass-posting) that lower acquisition costs and maximize profit margins.

Volume & Velocity Leverage: Establish full control over daily lead-generation volumes, using strict performance metrics as direct levers to intentionally scale and manipulate traffic according to business targets.

Operational Resilience (Anti-Ban Stability): Secure the company’s financial growth by building a bulletproof, policy-compliant account infrastructure that eliminates revenue drops caused by platform bans or restrictions

Key Responsibilities

• Crisis Management & Account Infrastructure Resiliency

• A/B test creatives, optimizing retention strategies, and conversion funnels.
• Analyze and systematically improve distribution channels based on performance metrics.

Ideal Candidate

We need a Performance Content expert, not just a creative. You must know how to scale automated content uniqueization while maintaining the critical product metrics (CTR /Retention/engagement) that trigger viral distribution.

Must-haves:

• 2-3+ years of experience as an Organic Growth Lead, Creative Lead, or Marketing Lead in the creator economy or digital media.
• An analytical mindset: understanding how to track and interpret key content performance metrics using tools like TikTok, Meta, Snap, and YouTube Analytics.
• Hands-on experience launching and scaling organic traffic through TikTok, Instagram, Facebook, YouTube, Snap, and Reddit.
• Experience in performance marketing to support organic results and initial growth.
• A deep understanding of the specifics of video distribution: algorithms, formats, platforms, policies, and trends.
• Experience building and managing creative teams (scriptwriters, editors, producers, designers).
• A portfolio with successful case studies: viral campaigns, scaled content strategies, subscriber growth, and increased views/revenue.
• Fluent in English, understanding of trends and pop culture in tier-1 countries.

Will be a plus:

• Understanding of the NSFW industry: content, restrictions, and audience behavior

What We Offer

• Fully remote work with a creative, ambitious, and globally distributed team.
• Competitive, executive-level compensation with performance-based bonuses/equity options.
• Paid vacation, sick leave, and personal days off.
• Fast feedback loop, high autonomy, and minimal bureaucracy.
• A unique opportunity to shape the future ecosystem of services and tools for top-tier global talent.

2. Expert level e-commerce domain and e-commerce platforms knowledge. You should have a deep understanding of e-commerce field, including major platforms, their functionality and capabilities. We primarily work with Magento (Adobe Commerce), but experience with other platforms is also valuable.

3. A strong work ethic and results-driven mindset. Successful project delivery can be challenging, but it is also highly rewarding - both professionally and financially.

    

We offer:
A highly skilled team, challenging projects, remote work with flexible hours, professional equipment, company-sponsored certifications, training, and opportunities for continuous learning and development.
Our benefits package includes 18 days of paid vacation, 5 paid sick days, and additional days off for important life events.

• Event-driven architecture: Kafka for async messaging, BullMQ for background job processing.
• Cloud & infrastructure: AWS SDK (S3, Bedrock), Docker/Docker Compose, Prometheus metrics, GitLab CI/CD

Nice-to-have

• Experience with Go or .NET.
