Full job description

Job Description: Backend Engineer (Blockchain Integration / REST API)Position Overview

We are hiring a Backend Engineer for a time-bound, private blockchain MVP. You will design and build the REST API layer that sits between web clients and a Hyperledger Fabric network: authentication, authorization, input validation, SDK-based chaincode invocation, and stable APIs for internal dashboards and public read-only endpoints.

This is a contract / project-based role with phased delivery. Project domain, client, and detailed specifications will be shared after NDA.

Role Summary

You will own the server-side application layer for a permissioned blockchain system. A separate Fabric engineer builds the network and chaincode; you integrate with it via the Fabric SDK, expose clean REST endpoints, enforce roles at the API level, and support frontend and QA during integration and release.

Strong API design, security discipline, and experience calling external systems (here: Fabric peers/orderers) are essential.

Key ResponsibilitiesAPI Design & Implementation

Build a REST API in Node.js (Express/Fastify) or Go (Gin or similar)
Implement endpoints for create, read, update/query, and transaction flows defined in project specifications
Integrate with Hyperledger Fabric using the Node SDK or Go SDK (invoke writes, evaluate reads)
Map API users to Fabric identities (certificates, MSP, or JWT claims → ledger identity)
Provide a public read-only API for verification-style queries (unauthenticated, rate-limited)
Produce OpenAPI (or equivalent) documentation for frontend and QA

Security & Authorization

Implement authentication for protected routes (JWT, sessions, or agreed IdP pattern)
Enforce role-based access control at the API layer (aligned with on-chain ACL rules)
Validate and sanitize all inputs (IDs, UUIDs, dates, enums) before SDK calls
Use HTTPS only; never store secrets or private keys in source control
Integrate with a secrets vault pattern for certificates and credentials (AWS Secrets Manager, Azure Key Vault, or equivalent)

Integration & Reliability

Work closely with the Fabric engineer on connection profiles, endorsement behavior, and error handling
Implement consistent API error responses (400 invalid input, 403 unauthorized, 404 not found, 5xx with safe messages)
Add logging (request ID, user/role, action, outcome — without sensitive payloads)
Optional: caching for high-volume read/query endpoints where appropriate
Support rate limiting on public endpoints

Testing & Delivery

Write unit and integration tests for API routes and SDK integration
Support end-to-end testing with frontend, chaincode, and QA
Assist with performance validation (read/write latency targets per NFR spec)
Contribute to deployment config (Docker, env vars, health checks) with DevOps
Document setup, environment variables, and runbooks for handover

Required Qualifications

3+ years backend development experience
Strong REST API design and implementation
Production experience with Node.js or Go (state one primary stack in your application)
Experience integrating with external services/SDKs (message queues, third-party APIs, or blockchain SDKs)
Solid authentication & authorization implementation (JWT, sessions, RBAC)
Strong input validation and API security practices
Experience writing automated tests (unit + integration)
Clear technical documentation and English communication for a distributed team
Comfortable working from written specs (PRD, data model, API requirements) under NDA

Preferred Qualifications

Direct experience with Hyperledger Fabric SDK (Node or Go) — invoke, query, wallet/identity management
Experience on blockchain, supply chain, asset tracking, or regulated systems (details under NDA)
AWS or Azure deployment (containers, API gateway, load balancers)
Docker and basic CI/CD familiarity
OpenAPI/Swagger for API contracts
Familiarity with structured logging and observability (metrics, tracing, health endpoints)
Understanding of permissioned blockchain concepts (channels, MSP, endorsement, commit flow)

Technical Environment (High Level)AreaStack / ExpectationAPIREST — Node.js or GoBlockchain integrationHyperledger Fabric via official SDKAuthJWT or session-based; role mapping to ledger identitiesFrontendWeb app (separate engineer) — consumes your APIBlockchain layerFabric network + chaincode (separate engineer)CloudMajor cloud provider (confirmed at kickoff)SecurityTLS, vault for secrets, API RBAC, rate limiting on public routes

Detailed endpoints, data models, and business rules are provided under NDA.

What You Will Deliver

By the end of the engagement:

Production-quality REST API with documented endpoints
Fabric SDK integration for all required invoke and query operations
Authentication and role enforcement on protected routes
Public read-only endpoints with rate limiting where specified
Test coverage for critical API paths and error cases
Deployment-ready service (containerized or as agreed) with configuration documentation
Successful E2E flows through API → Fabric → response in staging/production-like environment

Milestones and acceptance criteria are defined in the statement of work.

What We Are Looking For

Engineer who has shipped APIs used by real clients or internal products
Comfortable owning integration complexity (SDK errors, timeouts, idempotency considerations)
Security-minded: validation, authz, and secrets handled correctly by default
Works well alongside a blockchain specialist without blocking on every ledger detail
Pragmatic about MVP scope — core flows first, polish and hardening in later phases

Pay: ₹40,000.00 per month

Work Location: In person
