Senior Node.js Developer

For our client, we are enriching our existing development team which will be responsible for the further development of one of our most successful products. The product is an integrated delivery platform that leverages the depth and breadth of real-world engagements’ experience. It also enables cross-team collaboration, real-time transparency, and insightful decision-making. We’re looking for a Senior Back-End Engineer to join our growing platform team and build highly scalable, distributed systems using Node. js, NestJS, MongoDB, Azure, and messaging platforms such as Azure Service Bus.

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. You’ll be expected to think holistically — about performance, observability, testability, and supportability — throughout the software delivery lifecycle (SDLC), including the effective use of GenAI tools. Key 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. Required Skills & Experience: 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.
