Zenskar is an AI‑native financial‑technology startup that is rapidly reshaping how enterprises handle billing automation, revenue recognition, collections, usage metering and end‑to‑end financial workflows. Headquartered in Indiranagar, Bengaluru, the company combines deep domain expertise in finance with cutting‑edge machine‑learning models to deliver products that reduce manual effort, improve accuracy and accelerate cash flow for its B2B customers. Since its inception, Zenskar has raised multiple rounds of funding, expanded its client base across fintech, SaaS and enterprise segments, and built a culture that values curiosity, rapid experimentation and ownership. The SDE‑1 role is designed for early‑career engineers who are eager to work on a full‑stack product that touches both the user interface and the backend services. As a member of the core engineering team, you will be responsible for turning product ideas into production‑ready features, collaborating closely with product managers, designers and senior engineers. You will get hands‑on exposure to everything from API design and database schema modelling to UI development with modern JavaScript frameworks, and you will see your code run in a live, high‑traffic environment. Key Responsibilities: 1. Design, develop, and ship full‑stack product features from concept to production. 2. Build and maintain robust backend APIs and micro‑services using Python. 3. Create responsive user interfaces with React or similar TypeScript frameworks. 4. Model data and write efficient SQL queries for PostgreSQL databases. 5. Integrate third‑party CRM, ERP and payment gateways, handling retries and partial failures. 6. Implement validation, error handling and logging across the stack. 7. Debug performance bottlenecks and optimise both frontend and backend components. 8. Write unit and integration tests to ensure code quality and reliability. 9. Participate in code reviews, share knowledge and mentor peers. 10. Deploy features using Docker, CI/CD pipelines on AWS and monitor them in production. Tech Stack: Python, FastAPI/Flask, PostgreSQL, SQL, JavaScript/TypeScript, React, REST APIs, AWS (EC2, S3, Lambda), Docker, Git, CI/CD (GitHub Actions/Jenkins), unit testing frameworks (pytest, Jest). Growth Path: Starting as an SDE‑1, high performers can progress to SDE‑2, then to senior engineering roles, and eventually to technical lead or product engineering manager positions. Zenskar encourages continuous learning; you will have access to internal AI research, mentorship programs and the chance to contribute to AI‑driven automation projects. Why Join Zenskar?
