We are looking for a highly skilled Compliance and Risk Resolution Specialist to join our team. This role is designed for a professional who thrives in high-stakes environments and possesses deep expertise in payment infrastructure, risk mitigation, and provider relations.

As the primary lead for risk resolution, you will be responsible for ensuring the operational stability of our payment flows, navigating complex regulatory landscapes, and managing high-level provider partnerships.

 Key Responsibilities

• Incident & Restriction Management: Lead the resolution of account restrictions and service interruptions from major providers (Stripe, Payoneer, etc.).
• Dispute & Chargeback Defense: Develop and implement robust strategies for dispute representation to minimize losses and maintain healthy merchant standing.
• Strategic Risk Monitoring: Analyze key performance indicators (dispute rates, refund ratios, approval rates) to identify and mitigate systemic risks proactively.
• Anti-Fraud Optimization: Fine-tune 3DS protocols and internal risk filters to achieve an optimal balance between security and transaction throughput.

• Provider & Banking Relations: Serve as the technical point of contact for banks and gateways to resolve infrastructure bottlenecks and ensure compliance.

   

Professional Requirements

• Proven Expertise: Significant experience in Fintech or High-Risk payment processing.
• Analytical Proficiency: Ability to interpret complex data sets and translate them into actionable risk-mitigation strategies.
• Operational Independence: Capability to work without established manuals, creating new protocols and frameworks as the business scales.

• Language Skills: English Proficiency (C1/Advanced) is mandatory for high-level negotiations and professional correspondence with international partners.

   

🚫 This role may not be a fit if:

• You prefer working within strictly defined corporate playbooks or pre-set instructions.
• You are uncomfortable making autonomous, high-stakes financial decisions.

• You lack practical experience in handling merchant-level bans or provider audits.

   

✅ What We Offer

• Full Autonomy: You will lead the risk strategy with a high degree of trust and minimal micromanagement.
• High-Impact Role: Your decisions directly influence the company’s financial stability and growth trajectory.
• Professional Environment: A culture focused on logic, efficiency, and measurable results over bureaucracy.
• Direct Growth: Opportunities to scale your role and compensation alongside the success of our payment infrastructure.

We’re not looking for someone who just "finished a course." We’re looking for a Solo Player - a data-driven specialist who has managed campaigns end-to-end and knows how to scale based on cold, hard numbers.

The catch? We don’t have a massive buying department. You’ll be the sole owner of our traffic strategy and the ultimate decision-maker. No endless meetings, no "approval for the sake of approval." You run the show.

  What’s the mission?

• Full-Cycle Management: Launch and manage ads across Meta, TikTok, and beyond.
• Rapid Testing: Burn through creative/offer/landing page hypotheses faster than anyone else.
• Scale or Kill: Aggressively scale winning combos and cut losing campaigns without hesitation.
• System Hacks: Navigate bans, policy flags, and payment hurdles like a pro.

• Creative Synergy: Work closely with SMM to brainstorm high-converting hooks and concepts.

   

  It’s all about the numbers

We don’t care about "gut feelings." You need to speak the language of metrics to tell us exactly why a campaign is performing the way it is.

Your toolkit: CPC, CPM, CTR, CPA, ROI/ROAS, CR, and a solid grasp of LTV. You should be able to spot the bottleneck instantly: is it the creative, the traffic source, the lander, or the checkout?

🚫 This is NOT for you if:

• You’re used to working "by the book" and waiting for instructions.
• You can’t interpret metrics or turn data into an action plan.
• You’ve only worked as an assistant or handled "just one part of the process."

• Your English is "London is the capital of Great Britain" level. You need to be fluent enough to navigate global platforms, research trends, and communicate effectively.

   

✅ You’re our match if:

• You’ve independently managed and scaled high-budget campaigns.
• High-risk and Fintech are your natural habitat.
• You’re a self-starter who takes full responsibility for the budget and the outcome.
• English is your tool: You can easily read documentation, follow global ad trends, and communicate with the team.

 Why join us?

• Total Autonomy: You are your own Team Lead. We trust your expertise.
• Resource Access: Real budgets for testing and zero friction for launching new hypotheses.
• Direct Impact: No corporate layers. You work directly with the core team.
• Growth: Your income and role scale directly with your results.

📩 How to apply?

Skip the generic cover letter. Tell us:

1. Which traffic sources are you a beast at?
2. What have you launched and managed personally?
3. The Proof (Case Study): Goal → What you tested → The Stats (CPC / CPA / ROI) → Your conclusions.

Applications without data will be ignored. Let’s see what you’ve got!
