About the Role

Zime AI is building an AI-native behaviour and revenue intelligence platform powering real-time sales playbooks, conversation intelligence, call intelligence, and workflow automation used by revenue teams at scale. We’re looking for a strong

SDE-2

to build and own high-impact product features and backend systems. You’ll work on AI-powered application workflows, scalable APIs, modern frontend experiences, and mission-critical external integrations that power enterprise customer use cases. This is a high-ownership role where you will design, build, and ship production-grade systems end-to-end. Key Responsibilities

Design and build scalable product features using

Node.js / NestJS, TypeScript, and modern frontend frameworks (React.js / Next.js) Develop AI-enabled workflows using Python services and modern AI libraries Build and optimize REST APIs powering core product capabilities Implement async systems (queues, workers, background jobs) for real-time processing Develop third-party integrations (CRM, Call Recording, Calendar, Auth providers, SaaS APIs) Implement secure OAuth / SSO-based external authentication integrations Design robust SQL-backed data models and ingestion pipelines Improve system reliability, observability, and performance in production Own features end-to-end—from design to deployment and monitoring

What You Will Do Day-to-Day

Build backend services primarily using

Node.js / NestJS and TypeScript Develop product-facing APIs and AI-powered workflows Contribute to React / Next.js-based UI features using modern UI tools Build Python-based services for AI-enabled capabilities where needed Implement and maintain async processing systems and job queues Develop and maintain integrations with CRM, call recording, and other SaaS platforms Debug production issues across application and integration layers Participate in code reviews, sprint planning, and architectural discussions Ship production-ready features with strong ownership
