In this role, you will be solving complex, large-scale distributed systems problems serving millions of end users. If you thrive in fast-paced environments, love building systems from the ground up to handle massive scale, and possess strong computer science fundamentals, this role is for you.\nResponsibilities:\nArchitecture and Design: Architect, build, and maintain low-latency, high-concurrency microservices, data pipelines, and APIs.\nScalability and Performance: Optimize real-time data handling systems, ensuring high availability, fault tolerance, and efficiency in high-scale production environments.\nCode Excellence: Write clean, modular, maintainable, and highly optimized code adhering to SOLID principles and core data structures and algorithms.\nSystem Operations: Solve complex engineering bottlenecks across distributed caching, message queues, and persistent storage layers.\nTechnical Leadership (SDE 3): Mentor junior engineers, drive architectural discussions, conduct code reviews, and own critical modules end-to-end.\nRequirements:\nSDE 2 3 to 5 years of software development experience.\nSDE 3 4 to 7 years of software development experience.\nDomain Focus: Strong experience building high-scale internet systems in B2C, e-commerce, fintech, or ride-sharing companies with real-time user-handling requirements.\nCore Technical Expertise:\nProficiency in Golang (goroutines, channels, memory layout, and concurrency models).\nNote: Candidates with exceptional backgrounds in Java or C++ who demonstrate the ability to quickly adapt to Golang will also be considered.\nDeep expertise in Low-Level Design (LLD), High-Level Design (HLD), and core Data Structures and Algorithms.\nDistributed Systems: Hands-on experience with microservices architectures, event-driven messaging systems (e. g., Kafka, RabbitMQ), distributed caching (e. g., Redis, Aerospike), and relational/NoSQL databases.\nProblem Solving: Analytical, structured mindset with a proven track record of solving non-trivial engineering problems.","description_format":"text","description_chars":2183,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-19T11:28:18Z"}],"visa":[],"liveness":{"score":9,"band":"cold","label":"Long
