Microservices
We are looking for a Senior Backend Engineer with a strong background in building distributed, scalable, and high-performance backend systems. The ideal candidate has 6+ years of backend engineering experience, including 3+ years in microservices or distributed architecture, and deep expertise in Python, FastAPI, PostgreSQL, Redis, and async I/O patterns.
The candidate will own backend services end-to-end — from architecture and design to implementation, optimization, and production support — while working closely with cross-functional teams to deliver mission-critical systems.
Key Responsibilities
1\. Backend Architecture & Development
– Architect, design, and implement backend services using Python (preferably FastAPI) with clean, maintainable, and scalable code.
– Develop microservice components, service communication layers, and distributed workflows.
– Build APIs and backend modules optimized for performance, fault tolerance, and low latency.
2\. Distributed Systems & Scalability
– Design and maintain distributed systems capable of handling high throughput and large-scale operations.
– Implement inter-service communication patterns (REST, event-driven, message queues, pub/sub).
– Ensure system resiliency through redundancy, graceful degradation, and autoscaling strategies.
3\. Asynchronous & Event-Driven Architecture
– Build async workflows, background tasks, and pipeline services leveraging asyncio or async frameworks.
– 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.
– Strong expertise in Python and frameworks like FastAPI (or Flask/Django with async exposure).
– Deep understanding of async I/O, concurrency models, and asynchronous programming in Python.
– Strong experience with PostgreSQL (schema design, advanced queries, optimization).
– Hands-on experience with Redis for caching, queues, session management, and distributed patterns.
– Experience with event-driven architectures, message processing, or streaming systems.
– Solid understanding of system design, scalability principles, and API lifecycle management.
– Experience working with CI/CD pipelines, containerization (Docker), and cloud environments.
