• Develop and enhance tools, frameworks, and CI/CD pipelines that enable continuous delivery.
• Mentor and coach engineers across the organization, inspiring technical excellence and growth.
• Collaborate cross-functionally with product, design, and business teams to translate business requirements into elegant technical solutions.
• Represent the organization in the technical community through contributions to open-source projects, technical publications, and industry forums.

Must Have Skills

• 8+ years of experience designing, building, and operating high-scale, mission-critical cloud-based production systems.
• Proven expertise in architectural patterns for distributed and federated microservices.
• Mastery of at least one of these platforms: GoLang, Python, or Java.
• Extensive experience in high-level service design with modular, composable, and extensible patterns.
• Demonstrated success with data models, data stores, and data lake architectures (e.g., MongoDB, ClickHouse, Spark).
• Experience developing and operating large-scale distributed systems with Kubernetes and Docker.
• Track record implementing real-time and low-latency high-availability applications (using technologies like Kafka or gRPC).
• Bachelor's or Master's degree in Engineering, Computer Science, or equivalent experience.
• Strong leadership capabilities with the ability to influence, partner, and collaborate across engineering organizations.
• Strategic thinking with the ability to balance technical leadership and business judgment when making technology decisions.

Nice to Have Skills

• Experience with AI infrastructure and technologies.
• Knowledge of RAG (Retrieve, Augment, Generate) models and their practical applications in business systems.
• Experience with agentic platforms and orchestrating multiple specialized agents for complex task management.
• Expertise in speech technologies and natural language processing.
