Associate Full Stack Engineer

Flatworld Solutions

Bangalore North, Karnataka, IndiaFull-timePosted Oct 5, 2026

Job description

Key Responsibilities

A. Rapid Prototyping

  • Build functional prototypes for multiple solution concepts in parallel — typically 2 to 4 week build cycles per idea.
  • Translate solution blueprints and wireframes from the AI Solutioning team into working, clickable applications.
  • Make pragmatic technical trade-offs: choose speed-to-demo over premature optimisation, while keeping the code clean enough to extend.
  • Rapidly evaluate and integrate third-party APIs, SDKs, and open-source components to avoid building from scratch. B. MVP Development & Deployment
  • Take one or two selected prototypes per cycle to production-grade MVP: authentication, data persistence, error handling, and responsive UI.
  • Own end-to-end deployment — containerise, configure environments, and deploy to cloud platforms (AWS, Azure, GCP).
  • Set up and maintain CI/CD pipelines so every MVP has a repeatable, one-command deploy path.
  • Ensure MVPs are demo-stable: seeded data, reliable uptime during pitch windows, and failure handling.
  • Instrument basic logging and monitoring so issues surfacing during a client demo can be diagnosed quickly. C. Client-Pitch Enablement (Build Support)
  • Prepare demo environments and walkthrough-ready builds ahead of client pitches; the AI Solutions Lead presents; you make sure it works.
  • Produce short technical notes and architecture diagrams the Lead can use to answer client questions during pitches.
  • Turn client feedback captured in pitch sessions into prioritised build tickets and rapid iterations.
  • Maintain a reusable component and boilerplate library so each new prototype starts further along. D. Engineering Practice & Collaboration
  • Maintain disciplined version control: feature branching, meaningful commit history, pull requests, and code review participation.
  • Write concise technical documentation — setup instructions, environment variables, API contracts, and deployment runbooks.
  • Collaborate closely with business analysts, designers, and the AI Solutions Lead in short, iterative cycles.
  • Contribute to internal accelerators and shared tooling that shorten the path from idea to demo.

Requirements

Mandatory Technical Requirements The following are non-negotiable for this role:

  • JavaScript / TypeScript: Strong proficiency with modern JS/TS. Hands-on production experience with React and at least one of Next.js or Express.js. [MANDATORY]
  • Databases: Working experience with MongoDB and PostgreSQL — schema design, indexing, query optimisation, and migrations. [MANDATORY]
  • Application Deployment: Demonstrated experience deploying and running applications in a live environment — containerisation (Docker), environment configuration, and cloud or PaaS deployment. [MANDATORY]
  • Version Control: Proficiency with Git and GitHub (or GitLab / Bitbucket) — branching strategies, pull requests, merge conflict resolution, and CI/CD integration. [MANDATORY]
  • REST API Development: Ability to design, build, document, and secure RESTful APIs. [MANDATORY] Strongly Preferred
  • Vector Databases: Hands-on experience with Pinecone, Qdrant, Chroma, or pgvector — embedding storage, similarity search, and retrieval tuning.
  • Frontend Depth: Tailwind CSS, state management (Redux Toolkit, or React Query), and component-driven development.
  • Backend Patterns: Asynchronous processing, job queues, caching (Redis), and webhook handling.
  • Cloud Services: Familiarity with AWS (EC2, S3, Lambda), Azure, or GCP core services. Advantageous (ML / AI Exposure) Not required, but a clear differentiator for this role:
  • Working knowledge of LLM APIs (OpenAI, Anthropic, Google) — prompt construction, streaming responses, token and cost management.
  • Experience building RAG pipelines: document chunking, embedding generation, and retrieval-augmented response flows.
  • Familiarity with orchestration frameworks such as Lang. Chain, Llama. Index, or agentic patterns.
  • Exposure to Python for ML workflows, or integrating Python ML services into a Node.js application.
  • Understanding of core ML concepts: model evaluation, embeddings, fine-tuning trade-offs, and inference cost. What We Look For (Beyond the Stack)
  • Bias toward shipping — you would rather have something working and imperfect than perfect and unbuilt.
  • Comfort with ambiguity: specifications will sometimes be a wireframe and a conversation.
  • Breadth over narrow specialisation; genuine curiosity about unfamiliar tools.
  • Ability to estimate honestly and flag scope risk early rather than late.
  • A public portfolio, GitHub profile, or side projects that show what you build when nobody assigns it.

Qualifications

  • Bachelor’s degree in Computer Science, Information Technology, Engineering, or equivalent practical experience.
  • 3 – 5 years of hands-on full stack development experience with at least one application taken from zero to live deployment.
  • Prior experience in a startup, product studio, innovation lab, or fast-paced consulting environment is a plus.

Benefits

What We Offer

  • Variety — you will build across multiple domains and problem spaces rather than one product forever.
  • Direct line of sight from your code to a real client decision.
  • Freedom to pick the right tools for each prototype, within sensible guardrails.
  • Mentorship from the AI Solutions Lead and exposure to enterprise solutioning practice.
  • Learning budget for AI/ML upskilling and cloud certifications.
  • Competitive compensation with a clear path toward Senior Engineer or Solution Engineer tracks.
