  • 6-10 years of professional software development experience.
  • Strong proficiency in Java, Spring Boot, and Microservices design.
  • Solid understanding of data structures, multithreading, and design patterns.
  • Experience with message queues (Kafka/RabbitMQ) and databases (MySQL, PostgreSQL, MongoDB).
  • Familiarity with CI/CD pipelines, Docker, Kubernetes, and cloud platforms (AWS/GCP).
  • Excellent problem-solving and communication skills.

Nice-to-Have
  • Exposure to distributed systems, billing platforms, or large-scale data processing.
  • Knowledge of Python/Go for microservices scripting or automation.
  • Knowledge of ML, Big Data and AI.
  • Open-source contributions or technical blogging.

Why Join Us
  • Work on modern, high-impact systems used by global enterprises.
  • Competitive compensation with performance bonuses.
  • Flexible work environment and opportunities for career advancement.
  • Collaborative culture with a focus on engineering excellence.

Benefits
Zuora offers a comprehensive total rewards package designed to support ZEOs' wellbeing, growth, and flexibility. While specific offerings may vary by country, we typically provide:

  • Paid parental leave (including fully paid leave for eligible ZEOs, subject to local policy)
  • Learning & development stipend to support ongoing growth
  • Opportunities to volunteer and give back, including charitable donation matching where available
  • Mental wellbeing resources and support
