Role Overview
Design, build, and operate the server-side systems that power our screen recording platform. This role focuses on developing scalable, reliable backend services and APIs that support recording session orchestration, large file ingestion, and secure data handling. You will be a core contributor to a Java-based, cloud-native microservices architecture that supports real-time and asynchronous workloads at scale.
Key Responsibilities
Service & API Development
- Develop and maintain backend services using Java and Spring Boot for well-defined modules.
- Build and enhance RESTful APIs for platform features such as session lifecycle, uploads, and user management.
- Implement file and chunk upload workflows with basic retry and error handling mechanisms (following existing patterns).
- Work with cloud-managed databases to ensure efficient data storage and retrieval.
- Integrate authentication and authorization mechanisms using established frameworks and guidelines.
Architecture, Quality & Reliability
- Develop a solid understanding of the existing microservices architecture and service interactions.
- Contribute to low-to-medium complexity design discussions within the team.
- Write clean, modular, and testable code with appropriate unit and integration tests.
- Actively participate in code reviews, both giving and incorporating feedback.
- Implement basic logging, metrics, and monitoring hooks as per team standards.
- Identify and fix performance bottlenecks in owned components.
Data Handling & Reliability
- Implement reliable data handling logic (e.g., retries, validation, error handling) using established patterns.
- Ensure data consistency and correctness within owned services.
- Handle moderate-scale data flows with guidance on edge cases (e.g., partial failures, duplication).
Collaboration & Execution
- Collaborate closely with frontend, desktop, and backend engineers to deliver features end-to-end.
- Participate in sprint planning, task breakdown, and estimation.
- Communicate progress, blockers, and risks clearly and proactively.
- Work with QA and product teams to ensure feature completeness and quality.
Incident Handling & Debugging
- Assist in incident response and root cause analysis for production issues.
- Fix bugs and ensure proper regression coverage.
- Escalate complex issues appropriately with sufficient context.
