Zenskar, an AI-native billing and revenue automation platform, is hiring an SDE-1 for its Bengaluru office (Indiranagar, hybrid, 3 days a week in office). This is a full-stack role across product UI, backend services, data models and integrations. The backend uses Python and Postgres on AWS; the frontend uses modern JavaScript/TypeScript. Early projects may include building end-to-end workflows, making API errors clear in the UI, improving CRM/ERP/payment integrations, speeding up slow screens, and writing AI agents for customer use cases. Requirements: 1-3 years of software development experience (substantial internships and strong projects count), comfort in one mainstream language and willingness to work in Python, and a solid grasp of HTTP, APIs and databases. Billing or accounting knowledge is not required.
