  • 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 developing with Ruby on Rails, JavaScript (TypeScript), Golang, MySQL, and NoSQL databases.
  • 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.
