Knowledge and Experience
  • Bachelor's degree in Computer Science, or equivalent practical experience.
  • 10+ years of software development experience with strong foundations in data structures, algorithms, and distributed systems.
  • 7+ years of backend experience building, deploying, and operating large-scale distributed systems in production.
  • Deep expertise in system design, API design, scalability, and performance tuning, with strong SQL proficiency and an understanding of analytical query patterns.
  • Proficiency in at least one modern backend programming language (Java preferred).
  • Hands-on experience with cloud-native architectures, containerization, orchestration, and CI/CD pipelines.

  • Experience building enterprise-grade analytics infrastructure or data platforms that handle high-volume, low-latency analytical workloads.
  • Proven ability to influence architecture and technical strategy across multiple teams.
  • A track record of mentoring engineers and scaling engineering organizations.
