• Strong qualitative research skills, including session recording analysis, heatmap interpretation, user interviews, and usability testing, with the ability to translate observations into actionable design hypotheses
• Proficiency in building user flow maps and user journey maps to visualize and communicate complex flows
• Experience creating app store creatives (screenshots, feature graphics, listing assets) for App Store and Google Play, with familiarity with ASO visual best practices
• Practical experience designing for both WordPress (page builders like Elementor or Gutenberg, reusable block patterns, dynamic content) and custom frontend hand-off, with basic knowledge of HTML, CSS, and JavaScript for effective collaboration with developers across both stacks
• Proficiency in designing responsive user interfaces for web and mobile applications, grounded in user-centered design principles and information architecture
• Strong visual design skills (typography, color theory, layout, hierarchy)
• Experience working within established design systems (components, tokens, guidelines) and proficiency in Figma for prototyping and rapid iteration
• Experience designing for multi-language and multi-regional products, with understanding of how localization affects layout, typography, content density, and visual hierarchy
• Proficient English skills (B2+ level) both written and spoken, with strong communication, teamwork, and a user-focused mindset with attention to detail

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!
