RESPONSIBILITIES

Backend Architecture and API Development

• Design and implement highly available microservices using Spring Boot, Spring WebFlux, and FastAPI.
• Build clean API interfaces, efficient data flows, and resilient backend architectures.

Event-Driven and Real-Time Systems

• Develop and maintain event-driven systems using Apache Kafka for async processing and platform-wide data synchronization.

Caching and High-Performance Systems

• Leverage Redis for caching, queuing, and real-time operations to reduce latency and increase throughput.

AWS Engineering

• Deploy and maintain cloud-native services using AWS technologies including EC2, Lambda, API Gateway, SQS, SNS, DynamoDB, and CloudWatch.
• Serverless is considered a nice-to-have skill.

Full-Stack Collaboration

• Work with frontend teams using TypeScript frameworks like React or Next.js, ensuring seamless integration between UI and backend services.

Automation and Workflow Enablement

• Integrate and extend automation workflows using n8n, enhancing APIs and supporting operational efficiencies.

Security, Observability, and Reliability

• Implement best practices for authentication, permissions, API security, error handling, monitoring, tracing, and alerting.
• Ensure fintech-grade engineering standards such as idempotency, audit logging, retriable flows, and compliance-aligned design.

Cross-Functional Collaboration

• Partner with Product, AI, Data, and Operations teams to define requirements and deliver end-to-end features aligned with business goals.

Technical Leadership

• Lead code reviews, mentor junior engineers, establish best practices for CI/CD and DevOps.
• Drive architectural decisions and contribute to long-term technical vision.

THINGS YOU WILL DO

• Build new backend services from scratch using Spring Boot/WebFlux, FastAPI, or AWS components.
• Design and maintain Kafka-based event-streaming pipelines for payments, notifications, and AI-driven workflows.
• Implement high-performance caching layers using Redis.
• Own and evolve core platform components with strong architectural thinking.
• Write clean, testable, maintainable production-grade code.
• Implement observability patterns across services, including logs, metrics, and tracing.
• Collaborate on frontend integrations with TypeScript and modern UI frameworks.
• Contribute to automation workflows in n8n backed by secure backend logic.
• Build production-ready systems with proper handling of retries, circuit breakers, and security hardening.
