Designation: Full stack Developer

Location: Noida / Delhi NCR (Hybrid)

Experience: 4-7 Years

Notice Period: Immediate to 30 Days Preferred

Role summaryWe are seeking a Senior Full-Stack Developer to own the web application layer of a new B2B platform being delivered to a client. Client and project details are confidential and will be disclosed at onboarding under a confidentiality agreement.

The role covers the full application layer: internal dashboards and workflow tools, a gated customer portal with secure document upload, user registration and authentication, subscription and credit-based billing, and integration with a third-party CMS via REST APIs. The developer works within a small senior delivery team - a Solution Architect who owns the technical design, and an AI Engineer whose LLM-backed APIs the application consumes - and demonstrates completed work in fortnightly sprint reviews with client stakeholders present.

EolasFlow is an AI-native engineering team: AI-assisted development (Claude Code, Cursor, GitHub Copilot or equivalent) is the standard working method, and candidates are expected to already work this way.

Key Responsibilities

- Build responsive web applications in TypeScript/React from agreed designs and API contracts
- Implement user registration, authentication and role-based access control (OAuth2/JWT, multi-tenant patterns)
- Build a gated customer portal including secure document upload and content approval workflows
- Integrate subscription and credit-based billing (Stripe or equivalent), including webhook handling and a transaction ledger
- Integrate third-party platforms via REST APIs, including a CMS/publishing system
- Own application infrastructure: Docker, CI/CD pipelines, environments,



cloud deployment and monitoring
- Consume LLM-backed APIs, handling streaming, latency and failure states appropriately in the user experience
- Deliver tested, documented, production-quality code; AI-generated code is subject to the same review standard as hand-written code
- Present completed work in fortnightly sprint reviews

Required Skills and Experience

- Minimum 4 years of professional full-stack development
- Solid TypeScript and React (Next.js preferred)
- Node.js or Python backend development (Express/FastAPI or similar); sound REST API design
- OAuth2/JWT authentication, role-based access control and multi-tenant application patterns
- Payments integration with Stripe or equivalent: subscriptions, metered/credit billing, webhooks
- PostgreSQL, including schema design for transactional systems
- Docker, CI/CD (GitHub Actions or similar) and one major cloud platform (AWS, Azure or GCP)
- Demonstrable experience integrating third-party REST APIs into production applications
- At least one shipped production feature built on an LLM API (OpenAI, Anthropic or similar)
- Daily, fluent use of AI-assisted development tools (Claude Code, Cursor, GitHub Copilot or equivalent), with sound judgement on accepting, rewriting or rejecting AI-generated code; this will be assessed through a live practical exercise during selection
- Fluent written and spoken English; able to present work to non-technical stakeholders

Desirable

- Vector database exposure from the application side (pgvector, Qdrant, Pinecone)
- Marketplace or two-sided platform features: listings, matching, notifications
- WordPress REST API or other publishing-platform integration experience
- Transactional email at scale (SES, SendGrid)
