Our mission is to build a true alternative to traditional app stores - fueled by rewards and data - and create a new, performance-first growth engine for mobile app advertisers.

About the Role
We are looking for a skilled React Native Engineer to help build and scale Scrambly's mobile app for iOS and Android. In this role, you will own the end-to-end implementation of key features for a high-traffic platform serving millions of users globally. You will be responsible for translating product requirements into robust software, ensuring that our mobile experience remains user-centric and competitive.

Your primary focus will be on writing performant TypeScript code within a modern React Native stack. You will play a crucial role in maintaining app stability, keeping the application fast, reliable, and easy to maintain. This position offers a strategic opportunity to impact business metrics directly by reducing technical debt and optimizing application performance.

Success in this role requires active cross-functional collaboration. You will work directly with Backend, QA, and Product teams to clarify requirements, solve complex engineering challenges, and deliver a seamless UX. Additionally, you will contribute to architectural discussions, helping to shape the technical direction of the product alongside senior engineers.

Key Responsibilities

• Design & Implementation:
  • Develop and maintain high-quality cross-platform applications using React Native and TypeScript
  • Build reusable UI components and highly performant lists (utilizing tools like FlashList or FlatList) that strictly adhere to design specifications
  • Integrate mobile apps with backend services via RESTful APIs and WebSockets to ensure real-time data synchronization
  • Debug platform-specific issues using Xcode and Android Studio, and write or modify native modules (Swift/Kotlin) when standard libraries are insufficient
• Engineering Standards & Quality:
  • Champion code quality by writing clean, testable TypeScript code and actively participating in peer code reviews to ensure standards for readability and maintainability are met
  • Contribute to the long-term health of the codebase by identifying and fixing technical debt and improving overall test coverage
  • Participate in architectural discussions, offering input on state management (e.g., Redux Toolkit, Zustand) and navigation patterns to improve scalability
• Performance, Reliability & Collaboration:
  • Monitor production stability using tools like Sentry or Crashlytics, proactively identifying and fixing crashes or errors
  • Optimize app performance by focusing on specific metrics such as frame rates, memory usage, app size, and battery consumption
  • Assist in maintaining CI/CD pipelines to ensure smooth and reliable releases to the App Store and Google Play
  • collaborate effectively with non-technical stakeholders to explain technical constraints and propose viable solutions

Requirements

• 3+ years of professional software engineering experience, with at least 2 years strictly focused on React Native development
• Strong proficiency in TypeScript and the React Native ecosystem (CLI, Hermes, debugging tools)
• Solid understanding of iOS and Android build systems (Gradle, Pods, signing/provisioning). You must have the ability to read native code (Swift/Kotlin) to debug platform-specific issues

Our mission is to build a true alternative to traditional app stores - fueled by rewards and data - and create a new, performance-first growth engine for mobile app advertisers.

About the Role
As a Senior PPC Manager (Google) at Scrambly, you will own and scale our paid search acquisition across Google and Microsoft, turning it into a stable, profitable and automation-driven growth engine. Google Ads is the primary channel, and you will also develop and expand additional search-based acquisition sources, including Microsoft Ads.

This is a hands-on, performance-focused role. You will be responsible for end-to-end campaign performance, scalability, and long-term channel stability - not campaign maintenance. You will design and own the campaign architecture, conversion structure, and value logic that drives sustainable budget growth while maintaining profitability.

You will work closely with the Head of User Acquisition, acting as the strategic owner of paid search as a core revenue channel. Your goal is to build systems and processes that make performance explainable, repeatable, and scalable - not dependent on short-term spikes or one-off wins.

If you thrive on building durable growth engines with meaningful ownership and autonomy, this role is for you.

Key Responsibilities

• Paid Search Strategy & Execution
  • Own end-to-end performance of Google Ads (Search, PMax, Display, YouTube) and Microsoft Ads for our app portfolio
  • Define and execute the paid search acquisition strategy across platforms, aligned with business goals and profitability targets
  • Build and maintain stable, structured campaign architectures with clear conversion windows, value weighting, and signal strategy
  • Drive sustainable budget growth while maintaining or improving efficiency - scaling budgets from high five-figure to high six-figure monthly ranges
  • Develop a documented scaling and testing roadmap with clear milestones and success criteria
• Automation & Systems
  • Design and implement automation systems (scripts, rules, monitoring workflows) that significantly reduce manual optimization effort
  • Build scalable processes for bid management, budget allocation, and performance monitoring
  • Continuously identify opportunities to replace manual work with systematic, repeatable solutions
• Performance Analysis & Reporting
  • Own performance reporting tied directly to business outcomes, using tools such as GA4, Mixpanel/Amplitude, and Looker/Looker Studio
  • Maintain a clear understanding of value signals, cohort health, and attribution nuances across channels
  • Ensure channel performance is predictable, defensible, and clearly explainable to stakeholders
  • Operate comfortably with imperfect attribution and delayed revenue signals, making sound decisions despite incomplete data
• Collaboration & Communication
  • Work closely with the Head of User Acquisition to align on strategy, priorities, and growth targets
  • Clearly communicate performance drivers, scaling mechanics, and strategic trade-offs to the wider team
  • Proactively surface issues, flag risks, and propose solutions before they impact performance

Requirements

• 3+ years of hands-on Google Ads experience with a strong focus on Search and Performance Max campaigns
• Proven experience scaling paid search budgets in the high six-figure range with maintained or improved efficiency
• Experience in performance-driven verticals such as gaming (preferably web), fintech, utilities, or health
• Strong understanding of value-based bidding (ROAS/revenue optimization), including conversion windows, value weighting, and signal strategy
• Track record of designing and implementing automation: scripts, rules, monitoring systems, and workflows that reduce manual optimization
• Strong analytical fluency across advertising and product analytics platforms (GA4, Mixpanel or Amplitude, Looker/Looker Studio, Google Ads, Microsoft Ads)
• Comfortable operating with imperfect attribution and delayed revenue signals, with the ability to make sound decisions despite incomplete data
• Ability to clearly explain performance drivers and scaling mechanics to both technical and non-technical stakeholders
• Ownership-driven mindset: analytical, structured, systems-oriented, and focused on long-term profitability over vanity metrics
• Transparent and proactive: comfortable surfacing issues, making decisions without perfect data, and being accountable for outcomes
• Fluency in English (B2+)

Nice to Have

• Experience with Microsoft Ads at scale, beyond basic campaign mirroring
• Experience in mobile apps, rewards, or marketplace products
• Familiarity with building or contributing to internal BI dashboards and reporting infrastructure

What We Offer

• Direct ownership of a core revenue channel with visible business impact
• Close collaboration with the Head of User Acquisition and company leadership
• High autonomy in execution - a lean, low-bureaucracy environment where strong ideas are heard, tested, and implemented quickly
• The opportunity to build scalable systems and processes from the ground up
• Full-time & fully remote position
• 15 days of paid vacation days
• 5 days of paid days off
• 5 days of paid sick leave
• Maternity/Paternity leave
• National holidays based on the country of your stay
