• Design and optimize data pipelines and backend systems leveraging distributed technologies like Apache Kafka and Cassandra
• Drive platform modernization through Kubernetes-based deployments and configuration management using tools like Puppe
• Champion best practices in CI/CD, observability, security, and cloud-native architecture
• Collaborate with product and engineering teams to understand their needs and deliver reusable, scalable solutions
• Mentor other engineers, review design documents and code, and provide leadership in solving complex technical challenges
• Own the operational health of platform services, including reliability, uptime, and on-call rotations.

What you bring to the team

• 10+ years of experience in software engineering, with significant time spent on infrastructure or platform teams
• Proven track record of designing and operating petabyte-scale systems in production environments
• Deep experience with Java and working knowledge of other programming languages such as Python, Go or Scala
• Strong understanding and hands-on experience with RESTful service design and implementation
• Solid background in distributed systems and experience with technologies like Kafka, Cassandra, or equivalents
• Proficiency with Kubernetes (K8s), Terraform and Puppet, or similar deployment and configuration management tools
• Familiarity with AWS, Azure (preferred) or other public cloud ecosystems; understanding of cloud-native patterns and cost-aware design
• Experience with system monitoring, logging, and alerting tools (e.g., Prometheus, Grafana, ELK)
• Excellent problem-solving, communication, and collaboration skills with the ability to influence at multiple levels.

Nice to Have

• Experience building internal developer platforms or platform-as-a-service (PaaS) offerings
• Contributions to open-source tools and frameworks in the infrastructure or backend ecosystem. * Exposure to security best practices and compliance considerations in large-scale environments
