Senior Node.js Developer

You'll be building a new cloud-native announcements management system that handles vehicle condition codes, supporting both internal and customer-facing APIs with complex authorization rules and event publishing requirements. While this is a greenfield project, you'll need to analyze existing Ruby on Rails applications to understand business requirements and ensure the new system provides equivalent functionality. The ideal candidate will efficiently use AI tools to extract requirements from legacy code and build modern, scalable solutions using TypeScript and AWS serverless technologies.

Feel free to work remotely from anywhere across Lithuania or connect with colleagues at our Vilnius and Kaunas offices.

• Implement event-driven architectures using EventBridge, SNS/SQS, and DynamoDB Streams
• Design optimized data models for DynamoDB with proper partition strategies
• Build authentication and authorization systems for multi-tenant applications
• Create reusable Lambda layers and shared libraries
• Mentor junior developers on serverless best practices
• Establish CI/CD pipelines and automated testing strategies

Requirements

• Strong TypeScript and Node.js development experience (4+ years)
• Proven experience with AWS services (Lambda, API Gateway, DynamoDB, EventBridge, S3)
• Hands-on experience with AWS CDK or similar IaC tools
• Experience building microservices and distributed systems from scratch
• Strong understanding of serverless patterns and best practices
• Experience with event-driven architectures and asynchronous processing
• Proficiency with GitHub Copilot for accelerated development
