• PostgreSQL
• REST APIs

The platform is already functional and includes author, reviewer, editorial and admin workflows.

We are looking for an experienced Senior Next.js Developer / Frontend Tech Lead to work on an existing production application.

The primary requirement is to redesign and rebuild the frontend while reusing the existing backend, APIs, database and business logic wherever technically feasible.

This is not a greenfield project and we do not want unnecessary rewriting of the existing backend.

• Develop a completely redesigned, professional academic/publishing frontend.
• Convert Figma designs into clean, responsive Next.js interfaces.
• Integrate the new frontend with existing Node.js APIs.
• Maintain existing workflows and functionality.
• Work on author, reviewer, editor and admin dashboards.
• Develop responsive interfaces for desktop, tablet and mobile.
• Improve frontend performance, usability and maintainability.
• Ensure proper authentication and role-based access handling.
• Identify frontend/backend dependencies that may require minor backend changes.
• Follow clean coding standards and reusable component architecture.
• Work through Git with proper commits, branches and code reviews.
• Coordinate with UI/UX designer and QA during development.
• Ensure the redesigned application is production-ready.

Existing Modules

The existing platform includes functionality such as:

• Author registration/login
• Manuscript submission
• Manuscript tracking
• Peer-review workflow
• Reviewer dashboard
• Editorial workflow
• Publication processing
• Payment-related workflows
• Article/publication management
• Journal management
• Certificates
• Referral/credit functionality
• Admin dashboard
• Reports and operational dashboards

The exact modules and workflows will be provided during the project.

Required Skills

Must Have

• 4+ years of professional React/Next.js experience
• Strong Next.js knowledge
• React + TypeScript
• JavaScript/TypeScript
• REST API integration
• HTML/CSS
• Responsive design
• Git/GitHub/GitLab
• Experience working with existing production codebases
• Good understanding of authentication and authorization
• Ability to understand backend APIs and database relationships

Good to Have

• Node.js
• PostgreSQL
• Tailwind CSS
• Next.js App Router
• Dashboard/SaaS application development
• Experience with complex multi-role applications
• Experience with academic, publishing, research or workflow-based platforms

What We Are Looking For

We are looking for someone who can understand an existing application before changing it.

You should be comfortable working with an existing codebase rather than expecting to rebuild everything from scratch.

Strong attention to:

• UI quality
• UX
• Performance
• Clean architecture
• Reusable components
• Security
• Cross-browser compatibility
• Maintainability

is required.

Important

• Existing backend and database should be reused wherever possible.
• Do not rewrite existing functionality without approval.
• Existing production data must not be modified or exposed.
• Development will be performed in a staging environment.
• Git-based development is mandatory.
• NDA and confidentiality agreement will be required.
• Ownership of the developed code and project deliverables will belong to the company.

Selection Process

Shortlisted candidates will first be asked to:

1. Review the existing application architecture.
2. Understand the existing APIs and workflows.
3. Identify what can be reused and what needs modification.
4. Complete a small paid technical task.
5. Discuss the proposed development approach and timeline.

Candidates who demonstrate strong understanding of the existing system will be preferred.

Through the platform we believe that these professionals can be empowered to deliver better care to patients (like our families) throughout the globe.

In its current (and evolving) form, it is a live learning and engagement platform seeing tremendous week-on-week growth through stellar speakers and a very active early community. The product is in the growth stages and you will be playing a key role in steering the tech to create a scalable and lovable product experience.

We are backed by startup, VC and PE veterans including Kunal Shah (CEO, Cred), Raghunandan G (Zolve, ex-TFS), Avnish Mehra (Everstone) and more.

Medflix is a platform by PlexusMD (www.plexusmd.com/app), a network trusted and loved (4.4 stars on Playstore and 4.4 on Appstore) by more than 3 lakh doctors in India and working closely with leading healthcare providers and companies like AIIMS, Jaslok, Hinduja, Apollo, HCG, Elsevier, Association of Physicians of India, Indian Association of Cardio-thoracic surgeons, Society of Nuclear Medicine, Govt of Gujarat (HFW Dept), Govt of Haryana (SIFHW), McKinsey and company, Takeda, Mankind and others.

About the Role

Tech stack (expertise in all is not required, experience in some will be sufficient):

• React / Next.js (required, at least 1 year of experience)
• Express.js (required, at least 1 year of experience)
• Familiarity with cloud services (gcp / azure / aws)
• PostgreSQL (or expertise in any relational database)

Full-Stack Engineer (AI-Native) | 2-4 Years Experience

About the Role

We're hiring a Full-Stack Engineer who is equally comfortable building a polished Next.js interface and a reliable NestJS API behind it. You'll build customer-facing products, including AI-powered features like chat interfaces, streaming responses, and agent-driven workflows. You'll own features end to end, from database schema to UI, and use AI tools daily to ship faster without lowering the quality bar.

What You'll Do

Frontend

• Build responsive, accessible, high-performance UIs with React, Next.js (App Router, RSC) and TypeScript
• Build AI-facing interfaces: streaming chat UIs, tool-call/agent-status displays, and loading, error, and retry states for non-deterministic outputs
• Monitor web vitals and fix performance regressions

Backend

• Design and build scalable REST/GraphQL APIs and services with Node.js and NestJS
• Model, query, and optimize data in PostgreSQL (schema design, indexing, migrations) using an ORM like Prisma or Drizzle
• Implement auth, authorization, validation, background jobs, queues, and caching (Redis)
• Integrate LLM APIs (OpenAI, Anthropic, Gemini), including streaming (SSE/WebSockets), tool calling, retries, rate limits, and cost/latency control

AI-Assisted Engineering

• Use AI coding tools (Cursor, Claude Code, Copilot, etc.) for scaffolding, refactoring, debugging, and test writing
• Write and maintain project context for AI tools (rules files, AGENTS.md/CLAUDE.md, reusable prompts) so the whole team gets better output
• Review AI-generated code critically for correctness, security, performance, and maintainability

Team and Delivery

• Write unit, integration, and E2E tests, using AI to speed them up rather than skip them
• Take part in code reviews, sprint planning, architecture discussions, and on-call/incident follow-ups
• Document APIs, decisions, and runbooks clearly

Must-Have (Non-Negotiable)

Frontend

• Strong JavaScript (ES6+) and TypeScript
• React (hooks, state management, rendering behavior) and Next.js (App Router, SSR/SSG/RSC)
• HTML/CSS fundamentals, Tailwind or similar, responsive design, and accessibility basics

Backend

• Production experience with Node.js and a structured framework (NestJS preferred; Express/Fastify with good architecture is fine)
• Solid PostgreSQL skills: relational modeling, joins, indexes, transactions, query optimization
• API design: REST principles, pagination, versioning, error handling, input validation
• Authentication and authorization (JWT, OAuth2, sessions, RBAC)

Engineering Fundamentals

• Git, PR workflows, and code review habits
• Testing across layers (Jest/Vitest, React Testing Library, API/integration tests; Playwright/Cypress is a plus)
• Basic security awareness (OWASP top 10, secrets management, input sanitization)

AI-Assisted Development

• Daily, hands-on use of at least one AI coding tool (Cursor, Claude Code, Copilot, Windsurf, or similar)
• Ability to write clear prompts, give useful context, and break big tasks into steps an AI can handle
• Habit of reviewing, testing, and understanding AI output before committing it
• Basic understanding of how LLMs work: context windows, hallucinations, token cost, and why outputs vary

Nice to Have

• Redis, message queues (BullMQ, SQS, Kafka), or event-driven architecture
• Monorepo tooling (Turborepo, pnpm workspaces, Nx)
• Design system or component library work (shadcn/ui, Radix, Storybook)
• tRPC, GraphQL, or OpenAPI-driven type-safe clients
• Multi-tenant SaaS, payments (Stripe/Razorpay), or real-time features
• Open-source contributions, a side project, or shipped AI features you can demo

What We Expect From You

• Ownership: take a feature from schema to UI to production, and flag risks early
• Judgment over speed: AI makes you faster, and you're still accountable for every line you ship
• Security awareness: no secrets in prompts, no blind copy-paste of AI code, and sensitive data stays out of third-party tools
• Systems thinking: consider scale, failure modes, and cost, not just the happy path
• Learning speed: the AI tooling landscape changes every few months, and you keep up and share what works
• Clear communication: PRs, docs, and async updates that others can follow
