Job DescriptionSenior Backend DeveloperWe are looking for aSenior Backend Developerwho loves writing clean code and solving complex data challenges. In this role, you wont just be maintainingsystems; you will be actively building high-performance APIs, refining data pipelines, and optimizing how our applications handle massive, parallel workloads.Key Responsibilities
• Feature Development:Build and ship production-grade APIs, working primarily in Java with some functional logic in Scala.
• Code Craftsmanship:Drive the development lifecycle by reviewing peer code and translating complex technical requirements into scalable software.
• Performance Engineering:Write highly optimized code for parallelism and concurrency, ensuring our applications can handle heavy data loads without bottlenecks.
• Distributed Systems Architecture:Design, build, and maintain highly scalable distributed systems that process millions of events per day with low latency and high availability.
• Data Pipeline Development:Build and optimize real-time and batch data pipelines using Apache Spark and/or Apache Flink to process large-scale datasets efficiently.
• Observability:Use Splunk and Grafana to monitor application health and write PromQL queries to troubleshoot and optimize performance.
Required Skills & Experience
• The Stack:Deep expertise in Java
• Distributed Systems:Hands-on experience designing and operating highly scalable distributed systems, including understanding of CAP theorem, eventual consistency, and distributed consensus protocols.
• Data Processing Frameworks:Production experience building data pipelines with Apache Spark and/or Apache Flink for both batch and stream processing workloads.
• Storage Systems:Practical experience with distributed storage systems such as Apache Cassandra (or similar NoSQL databases) and PostgreSQL, including schema design, query optimization, and operational management.
• Data Structures:Advanced knowledge of data structures and experience building robust data pipelines.
• Containerization:Familiarity with Docker and Kubernetes for daily development and deployment.
Required Skills & Experience
• 5 yearsbackend engineering experience with advanced Java knowledge (JVM internals, concurrency, multithreading).
