Job Description
We are seeking a high-caliber Senior Full-Stack Engineer to lead the design, development, and deployment of our next-generation intelligent applications. In this role, you will bridge the gap between robust full-stack architecture and smart artificial intelligence integrations. You will be responsible for building scalable Node.js microservices, crafting intuitive React interfaces, and embedding AI capabilities (such as LLM APIs, autonomous agents, and smart workflows) to solve complex user problems. As a senior member of the team, you will champion technical excellence, mentor junior developers, and influence our product roadmap. The core responsibilities for the job include the following: AI Integration and Engineering: - Architect and implement backend systems that interface with Large Language Models (LLMs) and other AI services via APIs (e. g., OpenAI, Anthropic, or custom internal model endpoints). - Build middleware to handle prompt engineering, context orchestration, and structural parsing of AI responses into application logic. - Implement guardrails, caching layers, rate-limiting, and evaluation metrics for AI model outputs to ensure reliability, security, and cost-efficiency. - Stay up-to-date with emerging generative AI patterns, model capabilities, and integration techniques to drive product innovation. Full-Stack Development: - Backend: Build, scale, and maintain highly performant, secure, and production-ready RESTful APIs and GraphQL services using Node.js (TypeScript/Express). - Frontend: Develop responsive, state-managed, and visually seamless user interfaces using React.js and modern state management libraries (e. g., Redux Toolkit, Zustand, React Query). - Optimize application performance across the stack from database query optimization to frontend rendering bottlenecks. Architecture and Leadership: - Lead architectural decisions, promoting modular design, code reusability, and scalable system infrastructure. - Enforce high engineering standards through rigorous code reviews, automated testing (unit, integration, E2E), and comprehensive documentation. - Mentor and coach junior and mid-level engineers, fostering a culture of continuous learning and technical growth. - Work closely with Product Managers, UX Designers, and stakeholders to translate ambitious product visions into concrete technical execution. Requirements: - Experience: 7+ years of professional software development experience, with a proven track record of shipping production-grade SaaS applications. - Node.js Ecosystem: Deep expertise in backend development using Node.js and TypeScript, including asynchronous programming, event-driven architecture, and microservices. - React Ecosystem: Advanced proficiency in React, hooks, state management, and modern build tools (Vite, Webpack). - AI Practice: 1-2+ years of practical experience integrating LLM APIs and cognitive workflows into customer-facing applications. - Databases: Strong proficiency with relational databases (PostgreSQL, MySQL) and NoSQL databases (MongoDB). - Cloud and DevOps: Familiarity with cloud platforms (AWS, GCP, or Azure), Docker, and CI/CD pipelines. Soft Skills: - Exceptional problem-solving skills and a proactive ownership mindset. - Strong communication skills, with the ability to explain complex technical or AI concepts to non-technical stakeholders. - Proven ability to thrive in a fast-paced, iterative environment. Company Summary Zenskar is building new-age billing and pricing infrastructure for SaaS companies. As SaaS pricing evolves from vanilla subscription-based models to more granular usage-based models, billing and pricing infrastructure needs to be completely reimagined. Zenskar is founded by Apurv Bansal and Saurabh Agrawal, who sold their previous startups to Snapdeal and Gaana respectively. They have experience at organizations such as Google, Basepair, Elevation Capital, IIT Bombay, IIT Delhi, and Harvard Business School. We are building our founding team, and are looking for folks who are excited about learning and meaningfully shaping the trajectory of an early-stage startup from Day 0 in its journey. We enable SaaS companies to seamlessly generate bills and monitor usage for their customers. Over time, we will offer an entire bouquet of products related to billing, usage monitoring, pricing, forecasting, accounting, and related analytics. Why Join Us We don't take ourselves too seriously and know how to have fun. We're building an institution for the long term and believe in forging deep relationships. The health of our team is most important to us. We have closed an angel round of funding, and have commitments for our seed round, which ensure that we're well-capitalized for the next 2.5 years!
