Senior Node.js Developer

About the Position

We are seeking a Senior Node.js Developer with 7+ years of experience to join our team and build scalable back-end services using Node.js, NestJS, and MongoDB. This role is ideal for engineers with a deep understanding of service architecture and production operations, as well as a consultative mindset and strong problem-solving skills.

Responsibilities

• Design and implement distributed back-end services using Node.js, NestJS, and MongoDB within a microservices architecture.
• Deliver secure, production-ready APIs (REST and GraphQL) that meet SLAs for performance and availability.
• Leverage Azure platform services including Azure Service Bus, Event Hub, and Functions to build resilient systems.
• Participate in planning and refinement sessions - understand the 'why' behind the requirements and shape the 'how'.
• Apply GenAI tools effectively across the SDLC for documentation, testing, code generation, and analysis.
• Write automated tests and ensure strong test coverage using modern testing libraries and frameworks.
• Ensure proper instrumentation and monitoring is in place via tools like DataDog, and lead post-deployment support readiness.
• Collaborate closely with front-end engineers, product owners, and QA to ensure end-to-end quality and alignment.
• Contribute to pull requests and design reviews; mentor less experienced engineers by modeling best practices.

Requirements

• 7+ years of back-end development experience.
• Expertise in building distributed systems at scale using microservices and event-driven architectures.
• Experience with NextJs and back-end integration patterns (API routes, server-side logic).
• Knowledge of MongoDB (Document DB) including schema design, indexing, and performance optimization.
• Deep familiarity with RESTful APIs and GraphQL, including security and query performance tuning.
• Hands-on experience with Azure cloud services, especially Azure Service Bus and Event Hub.
• Experience with GenAI tools integrated into SDLC workflows (e.g., code assist, documentation, analysis).
• Strong understanding of non-functional requirements (NFRs) such as performance, reliability, and observability.
• Proficient with CI/CD pipelines, GitHub workflows, and Trunk-Based Development in a monorepo setup (e.g., Nx).
• Demonstrated ability to participate in agile ceremonies and technical discussions in scaled environments.

We Expect You to Have

• A consultative mindset and strong problem-solving skills.
• Ability to think holistically about performance, observability, testability, and supportability throughout the software delivery lifecycle (SDLC).

We Offer

• Opportunity to work with cutting-edge technologies and contribute to a successful product.
• Collaborative and innovative work environment.
• Potential for professional growth and development.
