Key Responsibilities • System Design & Architecture: Design and implement complex modules/services that meet functional, performance, and scalability requirements. Participate in Architecture Decision Records (ADRs) and contribute to cross-team architectural proposals. • Product Development: Build and evolve user-facing product features with a product mindset—understand user impact, measure outcomes, and iterate based on feedback. Deliver features on schedule and within budget. • GraphQL API Development: Design, implement, and optimize federated GraphQL APIs using Apollo Federation, ensuring schema integrity across subgraphs and cross-team collaboration via the GraphQL gateway. • Event-Driven Architecture: Build and maintain event-driven data pipelines using Apache Kafka (producers/consumers, Avro serialization, Confluent Schema Registry) to enable real-time data flows across microservices. • Observability & Reliability: Instrument services with OpenTelemetry for distributed tracing, metrics, and logging. Proactively identify and resolve performance bottlenecks. Champion system reliability through monitoring, alerting, and incident response. • Code Quality & Testing: Write comprehensive unit and integration tests (JUnit 5, Mockito). Maintain high code coverage (Jacoco, Codacy). Participate in design and code reviews with a focus on maintainability and security. • Mentoring & Leadership: Mentor, train, and serve as a knowledge resource for less experienced engineers. Lead technical discussions, drive adoption of best practices, and contribute to engineering culture. • Agile Collaboration: Participate in backlog grooming, sprint planning, and cross-functional collaboration with Product Management, Architecture Coalition, and peer engineering teams. • Documentation: Write and maintain technical documentation including ADRs, API schemas, runbooks, and design proposals following MADR-based templates. Preferred Qualification • Bachelor's degree in Computer Science, Computer Engineering, or equivalent. • 5–8 years of hands-on software development experience in a product-based or SaaS environment. • Advanced competency in object-oriented design, data structures, complexity analysis, and distributed systems. • Experience building and operating production microservices at scale. • Strong product mindset—ability to reason about user impact and make tradeoffs between speed, quality, and scope. • Experience leading or mentoring a team of developers; proven technical leadership and collaboration skills. • Experience working in Agile/Scrum teams with a focus on iterative delivery.
