  • 8+ years of professional software engineering experience, including a proven track record designing, building, and operating large-scale backend systems in production.
  • Strong proficiency in one or more backend languages (such as Java, Go, Python, or similar) and deep experience with distributed systems, microservices, and cloud-native development.
  • Hands-on expertise with databases (SQL and/or NoSQL), messaging systems, API design, and modern cloud platforms (for example AWS, GCP, or Azure) including container orchestration with Kubernetes.
  • Demonstrated strength in system design, debugging, and performance optimization, with the ability to make thoughtful trade-offs between speed, quality, and long-term scalability.
  • Proven ability to influence technical direction without direct authority, collaborating effectively with engineering, product, and business partners and communicating clearly with technical and non-technical audiences.
