Full Stack Engineer

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.
