Role Summary

We are looking for a Senior Backend Engineer with strong hands-on expertise in Node.js, TypeScript, distributed systems, microservices, and AWS cloud technologies. The engineer will be responsible for designing, developing, scaling, and supporting highly available backend services and APIs for customer-facing applications. The role requires strong ownership of backend architecture, application performance, production reliability, security, observability, and cloud-native engineering practices. Experience with React frontend development and/or Java/Spring Boot is beneficial but not mandatory.

Responsibilities

• Design, develop, and maintain scalable backend services and RESTful APIs using Node.js and TypeScript.
• Build reliable, secure, and highly available microservice-based and distributed applications.
• Design and implement efficient data models and access patterns using Amazon DynamoDB.
• Build cloud-native and event-driven backend solutions using AWS services such as ECS, Lambda, S3, SQS, API Gateway, and CloudWatch.
• Develop asynchronous processing workflows, background jobs, integrations, and messaging-based architectures.
• Define backend architecture, service boundaries, API contracts, data flows, and relationships between distributed components.
• Troubleshoot and resolve complex customer-facing and production issues across backend services and cloud infrastructure.
• Proactively identify and address issues related to performance, scalability, stability, security, availability, and extensibility.
• Participate actively in architecture discussions, technical design reviews, and code reviews.
• Ensure backend services meet defined standards for performance, reliability, security, maintainability, and quality.
• Write automated unit, integration, API, and service-level tests.
• Monitor and troubleshoot production applications using logs, metrics, traces, dashboards, and alerts.
• Maintain high availability and demonstrate strong ownership of customer trust and production reliability.
• Support and improve CI/CD pipelines, automated testing, containerization, and deployment processes.
• Collaborate with product managers, quality engineers, architects, and globally distributed engineering teams.
• Work in an Agile/Scrum development environment.
• Take end-to-end ownership of backend features throughout the complete software development lifecycle, from technical design and implementation through deployment and production support.
• Mentor engineers and contribute to backend engineering standards, development practices, and architectural guidelines.

Minimum Qualifications

• 7+ years of overall software engineering experience, with at least 5 years of strong backend development experience.
• Strong hands-on programming experience with Node.js, TypeScript, and JavaScript.
• Strong experience designing and developing RESTful APIs, backend services, and microservice-based applications.
• Solid understanding of data structures, algorithms, object-oriented principles, software design patterns, and architectural principles.
• Experience designing scalable and maintainable distributed backend systems.
• Hands-on experience with Amazon DynamoDB, including:
  Partition key and sort key design
  Global and local secondary indexes
  Query and access-pattern-based data modelling
  Performance and scalability considerations
• Strong experience developing cloud-native applications using AWS services such as:
  ECS
  Lambda
  S3
  SQS
  API Gateway
  CloudWatch
• Experience building asynchronous, queue-based, and event-driven processing workflows.
• Experience developing scalable, secure, resilient, and highly available applications.
• Experience with automated testing frameworks such as Jest, Mocha, or equivalent backend testing frameworks.
• Experience with Docker, CI/CD pipelines, and Jenkins or equivalent CI/CD platforms.
• Experience using Git-based source control and development workflows.
• Strong understanding of application monitoring, debugging, observability, incident troubleshooting, and production-support practices.
• Good understanding of API security, authentication/authorization, error handling, resiliency, and backend performance optimisation.
• Strong analytical, problem-solving, communication, and collaboration skills.
