• Design, develop, and maintain robust, scalable, and high-performance object oriented code in our backend services. • Develop public REST APIs using Java and internal gRPC APIs for inter-service and inter-system communication. • Craft systems designs, lead design decisions, and drive alignment with other senior engineers. • Write automated unit tests, integration tests, end-to-end tests, concurrency tests, load/performance tests. • Analyze existing systems to identify bottlenecks, tech debt, and implement scalability, and stability improvements. • Implement automation for testing, monitoring, healing, and scaling applications, continuous integration and deployment to reduce time to market. • Collaborate with cross-functional teams, including product managers, designers, and other engineers, to define and implement new features. • Conduct code reviews (comment, approve, seek revisions, merge), mentor junior and mid-level engineers, and actively promote engineering best practices. • Dive deep and troubleshoot complex issues, devise fixes, author root cause analysis documents, and ensure lasting performance and reliability. • Conduct objective and comparative analyses of competing technologies to advise the team of pros and cons of a technology solution. • Maintain robust documentation (design docs, run books, change management docs, and readiness plans). • Provide live-site support for production applications by monitoring systems, ensuring rapid incident resolution, and driving continuous improvement. • Drive cross-team projects as a single-threaded-owner (STO) or tech lead, and actively unblock other engineers to make progress.
