• Contribute to modernization efforts involving service architecture, shared libraries, and platform independence
• Support CI/CD pipeline adoption and improvements to engineering and deployment processes
• Participate in system design, architecture discussions, code reviews, and technical decision-making
• Troubleshoot production issues and provide operational support across multiple services
• Collaborate with engineers, product partners, and other stakeholders on cross-service initiatives
• Help improve and modernize an established advertising platform while reducing manual processes for internal users

• Approximately 3-5+ years of professional software engineering experience
• Strong experience with Java
• Hands-on experience developing applications with Spring Boot
• Experience with React
• Experience developing and integrating REST APIs
• Experience working with relational databases such as MySQL
• Strong understanding of full-stack application development

• Experience modernizing or decoupling legacy services
• Experience working with advertising technology, campaign management, or digital media platforms
• Experience supporting production systems and troubleshooting issues across multiple interconnected services

The team owns more than ten services and components supporting the advertising ecosystem. Current initiatives include improving campaign trafficking and filtering capabilities, modernizing event infrastructure, migrating functionality to GraphQL, improving CI/CD processes, and enhancing the overall user experience.

You’ll join a full-stack engineering environment where engineers share responsibility across frontend and backend development. The workload is approximately balanced between the two areas, although there is currently a slightly greater need for strong backend Java expertise.
