- Develop event-driven components including producers, consumers, and event processors.
- Optimize I/O-heavy operations to maximize concurrency and throughput.
4. Data Storage, Pipelines & Caching
- Design relational schemas, write optimized SQL queries, and work with PostgreSQL performance tuning (indexes, partitions, query planning).
- Implement caching strategies, rate limiting, distributed locks, and session storage using Redis.
- Build data validation pipelines and compliance-driven data flows ensuring data correctness and auditability.
5. Security, Reliability & Observability
- Implement authentication, authorization, encryption, and secure API practices.
- Build monitoring, alerting, metrics, and tracing systems using modern observability tools.
- Diagnose production issues, identify bottlenecks, and drive long-term fixes and improvements.
6. Code Quality & Technical Leadership
- Conduct detailed code reviews and ensure engineering best practices across the team.
- Participate in technical roadmap planning, architectural discussions, and system design decisions.
- Mentor junior and mid-level engineers; drive a culture of technical excellence and ownership.
Required Qualifications
- 6+ years backend engineering experience.
- 3+ years building microservices or distributed systems.
