Tapjoy is a leading mobile advertising and monetization platform that empowers game developers to maximize revenue and engage users through innovative rewarded experiences. For over a decade, we've been at the forefront of mobile app monetization, connecting millions of users with engaging offers that provide tangible in-app value. Our Offerwall product is a cornerstone of this success, driving significant revenue for game developers and delivering a delightful, value-driven experience for users worldwide. We're a team of passionate innovators, dedicated to pushing the boundaries of what's possible in mobile advertising.

We're seeking an experienced Staff Software Developer who is passionate about building high-scale, resilient systems that drive real business impact. If you thrive on solving complex, real-time problems—from optimizing third-party integrations and sophisticated fraud detection to ensuring seamless user experiences—this position is for you.

As a technical leader on our Offerwall team, you will play a critical role in evolving our core monetization product, designing and implementing its next generation of technology. This is an exciting opportunity to lead impactful initiatives, architect robust solutions, and directly contribute to the financial success of countless mobile app developers and the engagement of millions of users globally. You will work at the intersection of rewarded advertising, advanced fraud prevention, and large-scale data processing, driving innovation that directly impacts our bottom line and industry leadership.

Your solutions will foster stronger collaboration and integration with other Ads products at Unity. You will mentor and guide engineers as they design, build, and deploy web applications and services. You will also play a key role in designing technical solutions that focus on system performance, reliability, and delivering business value at scale.

What you'll be doing

  • Architect & Design: Lead the technical design and architecture for Offerwall products, features, and critical strategic initiatives, collaborating closely with senior engineers and managers.
  • Develop & Innovate: Design, build, test, and maintain robust web applications, APIs, and datastores that power our core monetization platform.
  • Mentor & Drive Excellence: Mentor and guide engineers, fostering a culture of technical excellence and establishing effective engineering standards across the team.
  • Cross-functional Collaboration: Ensure seamless communication and collaboration with product, frontend, SDK, DevOps, security, and legal teams in a distributed environment.
  • Operate & Maintain: Ensure the high availability and reliability of our production services, including participation in on-call rotations and proactive system monitoring.

What we're looking for

  • High-Scale System Design: Demonstrated ability to design, build, and deliver large-scale, highly available web applications and REST APIs, including distributed cloud systems with complex business logic.
  • Core Technologies: Strong proficiency in backend development using any modern programming language (e.g., Java, Python, Go, C++, Ruby, etc.) with a willingness to adapt to the best tool for the job.
  • Observability & Data Streaming: Practical experience with observability platforms (logging, metrics, monitoring/tracing) and message bus technologies (e.g., SQS, Pub/Sub, Kafka) for managing complex data streams.
  • System Modernization: Proven track record of refactoring and redesigning legacy systems to meet evolving product requirements and enhance performance.
  • Operational Excellence & Mentorship: Experience running high-availability production services with on-call responsibilities, coupled with a commitment to mentoring engineers and fostering their skill development.

You might also have

  • Experience with advanced fraud detection techniques and systems.
  • Familiarity with advertising technology ecosystems and monetization strategies.
  • Hands-on experience with specific GCP services relevant to large-scale data processing or real-time systems.

Additional information

  • Relocation support is available for this position.
