• Lead mobile and web UI development, integrating advertising experiences (Google Ad Manager, AdMob, MoPub, AppLovin, ironSource, Unity Ads, Meta Audience Network) that balance exceptional UX, optimal performance, and revenue generation.
• Design and build scalable backend services, APIs, and data pipelines supporting ad delivery, analytics, and reporting while optimizing for low-latency, high-throughput workloads.
• Own full-stack features from requirements through deployment, making architectural decisions around scalability, reliability, and security while building and maintaining CI/CD pipelines and cloud infrastructure.
• Collaborate across teams (product, design, data, monetization) and conduct code reviews to mentor engineers, raise engineering standards, and deliver innovative solutions that drive business outcomes.
• Solve hard problems with creative solutions and have a good time along the way!

Qualifications

• 7+ years of professional software development experience with proven delivery of production mobile and web applications at scale, including strong expertise in mobile front-end development (Swift, Kotlin, React Native, Flutter) and modern Web UI development with React, JavaScript/TypeScript, state management, and performance optimization.
• Required hands-on Ad Tech experience with mobile advertising SDKs, mediation platforms, and ad lifecycle management, plus direct experience with one or more ad platforms such as Google Ad Manager (GAM), AdMob, MoPub, AppLovin, ironSource, Unity Ads, or Meta Audience Network.
• Demonstrated full-stack engineering expertise including backend development (Node.js, Java, Python, Go), API design (REST/GraphQL), databases (SQL and NoSQL such as PostgreSQL, MongoDB), event tracking, analytics pipelines, and microservices architecture.
• Strong system design and cloud platform experience (AWS, GCP, or Azure) with ability to architect scalable, low-latency solutions that handle high volume and large-scale data, plus understanding of Agile development methodologies.
• Bachelor's degree in Computer Science, Engineering, IT or related field (equivalent experience/training will be considered) and excellent communication skills to clearly describe complex technical issues to both technical and non-technical stakeholders.

While the above are core requirements, the follow specialized experience is highly desirable:

• Experience with monetization strategy, yield optimization, or revenue analytics including familiarity with ad performance metrics (eCPM, fill rate, ARPDAU, CTR, viewability) and exposure to programmatic advertising or RTB.
• Infrastructure-as-code experience (Terraform, CloudFormation, AWS CDK) and prior technical leadership or mentorship experience with track record of guiding and developing engineering talent.
• Experience with A/B testing frameworks, web application security (XSS, SQL injection), understanding of malware/malvertising threats, or knowledge of privacy regulations (GDPR, CCPA) and their impact on mobile advertising.
