Software Engineer- Backend

Job Role: Software Engineer — Backend & AI Infrastructure Location: Hybrid / Remote (India-based, U.S. overlap preferred) Experience: 4–6 years Type: Full-time Salary Range: 12 to18 Lakhs About Nexoar.ai Nexoar.ai is building the next generation of intelligent, autonomous enterprise systems. Our mission is to make data, automation, and intelligence work together seamlessly — powering decision-making and productivity at scale. We’re at the early build stage of our product journey, assembling a lean and ambitious engineering team that will architect and deliver a platform blending backend excellence with applied AI innovation. If you’re a software engineer with strong backend fundamentals, curiosity for modern technologies, and a desire to grow into AI and data infrastructure, this is your opportunity to be part of our founding build phase. What You’ll Do • Design and develop scalable backend services and APIs using Node.js (Express.js / NestJS). • Architect and maintain microservices for data-intensive and AI-integrated systems. • Build and optimize RESTful, GraphQL, and gRPC APIs for cross-platform use. • Collaborate with AI, frontend, and DevOps teams to deliver end-to-end product features. • Work with databases (PostgreSQL, MongoDB, Redis) and design efficient data models. • Implement containerized deployments using Docker and Kubernetes. • Develop or assist in building internal tools / dashboards using modern frontend frameworks (React, Vue, Angular, or Svelte). • Set up CI/CD pipelines and automate deployment processes. • Learn and contribute to AI/ML integrations — connecting with APIs and SDKs such as OpenAI, Hugging Face, AWS Bedrock, or LangChain. • Participate in architecture discussions, code reviews, and performance tuning. What You Should Bring • 3–6 years of hands-on backend development experience using Node.js (TypeScript / JavaScript). • Familiarity with at least one modern frontend framework (React, Vue, Angular, or Svelte) and frontend tooling (TypeScript, Webpack, Vite, etc.). • Solid understanding of server-side development and microservices architecture. • Hands-on experience with databases (PostgreSQL, MySQL, MongoDB, Redis) and data modeling. • Experience defining and consuming APIs (REST, GraphQL, gRPC). • Familiarity with cloud platforms (AWS, Azure, GCP) and their compute, storage, or serverless services. • Working knowledge of containerization (Docker, Kubernetes) and Infrastructure as Code (Terraform, CloudFormation). • Strong grounding in software engineering principles, design patterns, and testing frameworks (Jest, Mocha, Cypress). • Excellent problem-solving and debugging skills. • A strong desire to learn and evolve into AI, ML, and cloud infrastructure domains. Nice to Have • Exposure to AI/ML APIs and SDKs (OpenAI, Hugging Face, LangChain, TensorFlow.js, PyTorch). • Familiarity with vector databases (Pinecone, Weaviate, FAISS) and retrieval-augmented generation (RAG). • Experience with workflow orchestration, data visualization, or AI pipeline tools. • Prior experience in a startup or cloud-native environment. Why Join Us • Join the founding engineering team of a visionary AI startup. • Gain hands-on training and mentorship in AI, ML, and data-driven backend systems. • Work directly with architects and product leaders shaping enterprise-scale AI infrastructure. • Opportunity to grow into AI Platform Engineer / Tech Lead roles as we scale. • Competitive compensation and ESOP potential for early contributors. We’re Looking For • Curious, adaptable engineers who love solving complex problems and want to grow beyond backend development into the next generation of AI infrastructure engineering. • If you’re excited to build systems that blend data, AI, and automation, Nexoar.ai is where you’ll make it happen
