Fit4Me is looking for a Head of Payments who will drive revenue growth through payment infrastructure, billing logic, and optimization of the payment experience.

In this role, you will define the payment strategy, lead the development of the billing system, and make decisions that directly impact revenue, retention, and scalable growth across Tier 1–2 markets.
This role is for a leader who combines strategic thinking with a hands-on approach: someone who both defines the direction and drives execution.

 

This role is a great fit if you:

• Want to own the payments domain and drive revenue, not just manage processes.

• Think in terms of growth and understand how payments impact conversion, LTV, and product scalability.

• Can prioritize and cut through noise, making decisions where the balance between approval, cost, and risk delivers the best business outcome.

• Feel comfortable in a player-coach role: shaping strategy while staying hands-on with key initiatives.

Impact Areas

1. Payment Strategy & Revenue Growth
• Define the payment strategy as part of the overall growth approach, driving impact on revenue, LTV, and product scalability.
• Own key payment metrics (payment success rate, renewal rate, recovery rate) and continuously improve them through data-driven solutions.
• Build and optimize billing logic (retry, dunning, renewal flows) to maximize conversion and user retention.
• Prioritize initiatives by balancing conversion, cost, and risk based on business needs and growth stage.
• Optimize the payment experience in close collaboration with the Product team.
2. Payment Infrastructure & Scaling
• Build and scale the payment infrastructure: multi-PSP setup, routing, orchestration.
• Select and launch new payment providers, payment methods, and markets (Tier 1/Tier 2).
• Ensure stable payment processing while scaling traffic and revenue.

• Lead negotiations with payment providers and improve partnership terms.
• Own payment margin as part of the product’s unit economics.
4. Risk & Stability Control
• Monitor chargeback rate, fraud, and other risk metrics as key constraints for growth.
• Build approaches that enable scaling without exceeding risk benchmarks.
5. Team Leadership & Execution
• Lead Payment Operations and develop the team.
• Set priorities and ensure the right balance between strategic initiatives and operational execution.
• Work directly with the CEO, Product, and Marketing teams to drive growth initiatives.


 

What we expect from you

• 4–6+ years in payments / billing / subscription-based products, with direct impact on payment conversion, retention, or revenue.

• Experience working with high-volume payments ($3–5M+ monthly) and understanding how scale affects performance metrics.

• Building end-to-end payment flows: from payment methods (cards, PayPal, Apple Pay, Google Pay) that impact conversion, to subscription billing (recurring payments, retry / dunning logic, renewal flows, and declined payment handling).

• Strong understanding of unit economics (LTV, CAC, margins) and the role of payments within it, combined with the ability to analyze metrics, form hypotheses, and make decisions that impact revenue and scalability.

• Experience working with Tier 1 / Tier 2 markets and localizing payment methods.

• Building and optimizing payment infrastructure: PSPs (Stripe, Adyen, Braintree), routing, integrations, and launching new payment methods.

• Experience leading a payment function or team, building processes, and setting priorities.

• Upper-Intermediate (B2+) English for working with providers, negotiations, and optimizing partnership terms.

What success looks like in this role

• Payment infrastructure runs reliably at scale: high approval rates, controlled risk levels, and no critical revenue loss.

• Payments become a growth driver: increased payment conversion, improved renewal rates, and higher recovery of failed payments.

• A clear and effective payment strategy is in place: defined priorities, a strong balance between cost / conversion / risk, and a roadmap that supports product scaling.

• Payment processing costs are optimized without compromising performance: improved provider terms and efficient routing setup.

• Payment Operations runs as a well-structured system: stable processes, no operational bottlenecks, allowing you to focus on scaling and developing the function.

About Yanarchy

Yanarchy is a Los Angeles–based talent management agency working with media creators and digital talents as scalable businesses. We focus on sustainable growth, strong monetization models, and long-term value by combining creativity with disciplined financial and operational execution.

Content is one of our core growth engines. We're building a high-performance content operation where creativity is supported by data, clear processes, and continuous experimentation.

The Role

We're looking for a Head of Content who can build and lead a scalable content production system for Tier-1 markets (US, UK, Canada, Australia).

This is not a traditional creative leadership role focused only on ideas and content calendars.

Your mission is to transform content production into a predictable, high-performing operational system that consistently generates organic reach across major social platforms.

You'll work at the intersection of content strategy, production operations, audience psychology, and performance analytics—building workflows that allow creative teams to move fast while continuously improving content quality and distribution performance.

What You Will Do

Content Operations

Build and optimize the entire content production pipeline—from research and creative briefs to filming, editing, quality assurance, and handoff to the distribution team.

Create clear production workflows, ownership, and SLAs across every stage of the content lifecycle.

Continuously improve operational efficiency as production volume grows.

Content Strategy

Develop content frameworks tailored to Tier-1 audiences.

Translate platform trends, audience behavior, and performance insights into actionable creative briefs.

Ensure content is designed to maximize engagement, retention, and organic distribution.

Production Management

Coordinate collaboration between scriptwriters, creators, video editors, designers, and other creative contributors.

Establish structured filming requirements and content standards for talent.

Improve production consistency while maintaining creative quality.

Performance Optimization

Monitor key performance metrics, including:

• Hook Rate
• Watch Time
• Audience Retention
• CTR
• Engagement
• Shares

Work closely with the distribution team to analyze results, validate hypotheses, and continuously improve future content.

Use data—not assumptions—to guide creative decisions.

Content Scaling

Develop scalable approaches to content production through reusable formats, localization, AI-assisted workflows, and efficient repurposing strategies.

Increase output while maintaining platform quality standards and production efficiency.

Who We're Looking For

We're looking for someone who enjoys building systems as much as creating content.

You probably have:

• 3+ years of experience as a Head of Content, Content Operations Lead, Senior Content Manager, or similar leadership role
• experience managing high-volume content production for international or Tier-1 audiences
• deep understanding of Instagram, TikTok, YouTube Shorts, Facebook, and X algorithms
• strong knowledge of audience psychology, retention mechanics, and viral content patterns
• experience building production processes, SOPs, and scalable operational workflows
• experience leading cross-functional creative teams
• strong analytical mindset—you naturally connect creative decisions with performance metrics
• Upper-Intermediate (B2+) English or higher

Nice to Have

• Experience working in creator economy, media companies, or digital publishing
• Experience implementing AI tools into content production workflows
• Experience with localization and multi-market content strategies
• Understanding of performance-driven organic distribution
• Background in growth marketing or audience development

Success in This Role

After your first months, we expect you to:

• Build a structured, predictable content production pipeline.
• Improve collaboration across creative and distribution teams.
• Increase production speed without sacrificing quality.
• Continuously optimize content based on performance insights.
• Create repeatable systems that allow content output to scale efficiently.
• Help transform content into one of the company's strongest organic growth channels.

What We Offer

• Fully remote work
• High ownership and autonomy
