Collaborate with DevOps on AWS, Kubernetes (EKS), and CI/CD pipelines
Influence observability standards using OpenTelemetry, logs, metrics, and traces
Actively use and promote AI developer tools such as GitHub Copilot, Claude, ChatGPT and more
Define best practices for AI-assisted code generation, refactoring, testing, and documentation
Requirements:
8+ years of software engineering experience with 3+ years in architecture or senior technical leadership roles
Expert-level proficiency in Node.js, Express, TypeScript, and microservices architecture
Strong hands-on experience with Sequelize, PostgreSQL, MongoDB, Redis, and RabbitMQ
