About the Company
Doorpost Innovations is an Ahmedabad-based AI-first startup that delivers enterprise-grade platforms, microservices architectures, AI integrations, and data engineering solutions.
About the Role
We're looking for a Full Stack Engineer who can own features end to end, from the browser to the session layer to the integration, and who uses AI tools as part of how they work every day.
This is a hybrid role, and we're looking for self-driven professionals with 4-5 years of experience, based in Ahmedabad.
What you'll work on
SSO and identity flows (OAuth/OIDC, sessions, secure login and logout)
A Node.js backend-for-frontend: middleware, proxies, audit logging
Third-party API integrations, data sync, rules engines and multi-channel messaging
AI-assisted development, plus AI-powered features built with guardrails
What you bring
4–5 years of professional full stack experience
Strong Node.js (Express or similar), REST API design, and middleware patterns
Solid experience with Angular (or React with a willingness to work in Angular)
Hands-on experience with authentication: OAuth 2.0/OIDC, SSO, session and cookie security, CSRF, and preventing open redirects
Experience integrating third-party APIs and handling sync, retries, timeouts and failure cases
Comfort with SQL and/or NoSQL databases, query performance (no N+1s), and data consistency
Docker, CI/CD, environment-specific configuration, and cloud basics (AWS preferred)
Daily, practical use of AI dev tools such as Claude Code or Cursor, plus the judgement to review what they produce
Nice to have
AWS Cognito, Lambda/serverless, or API gateways
Multi-tenant SaaS and role-based access control
Messaging APIs (WhatsApp Cloud API, SMS/email providers)
Experience building LLM-powered features with guardrails
Writing automated tests for production readiness and release gating
Why join us
Real ownership of production systems, not just ticket work
An AI-first engineering culture
Close collaboration with a global product and engineering team
Compensation no bar for the right candidate.
