Position: Associate TechSpecialist / Tech Specialist- Fullstack with AI

Experience- 5 to 8 Years

Location- Pune (Hybrid)/Remote

ROLE OVERVIEW

Client builds products thatcombine a modern component-based front end, a large and mature server-sideJavaScript backend, and a growing suite of AI agent services. We're looking foran Associate Tech Specialist / Tech Specialist with 5+ years of experience whocan move comfortably across this stack: building responsive, component-drivenUIs, extending backend services and data models, and contributing toLangGraph-based agent workflows that call Claude models through AWS Bedrock.

This role suits specialistwho thinks in components and state, is equally at home in older prototype-basedJavaScript as in modern TypeScript, and has genuine hands-on experiencebuilding agentic AI features not just calling a model API. You'll also beexpected to use AI coding agents (like Claude Code) as part of your ownworkflow, while still owning, reviewing, and defending every line you ship.

KEY RESPONSIBILITIES

- Design, build, and maintain responsive front-end components using Lit (or equivalent modern component frameworks), including work that crosses Shadow DOM boundaries.
- Develop and extend backend services written in server-side ES5 JavaScript, alongside newer TypeScript and Python services.
- Build and consume REST APIs, including authentication and role-based access control (Basic Auth, OAuth, JWT).
- Model and query relational data, with attention to schema design, joins, and query performance.
- Contribute to AI agent services built on LangGraph, including graph design, state management, and checkpointing.
- Extend and debug Python/FastAPI services with typed, async code and Pydantic models.
- Write and maintain end-to-end and API tests with Playwright (or Cypress/Selenium),



including per-role permission checks.
- Participate in code review, Git branching/rebasing at team scale, and diagnosing GitHub Actions workflow failures.
- Bring up, debug, and operate local environments using Docker Compose.
- Use AI coding agents (e.g., Claude Code) responsibly scoping tasks clearly, reviewing generated output critically, and owning the final result.

REQUIRED SKILLS EXPERIENCE

FRONTEND

- JavaScript (ES6+) and TypeScript solid in both.
- HTML and CSS/SCSS, including responsive layout and how styling crosses a Shadow DOM boundary.
- A modern component framework Lit ideally, or solid React experience; what matters most is thinking in components, props, and state.
- Web components custom elements, Shadow DOM, reactive properties (direct experience is a plus, not a gate).
- Browser fundamentals ES modules, fetch, DevTools, and basic CSP debugging.

BACKEND

- Server-side JavaScript in ES5 prototype-based classes, no async/await; this is the largest body of code in the codebase.
- REST APIs building and consuming them, with authentication.
- Relational data modelling tables, references, joins, and query performance.
- Access control roles and permissions, Basic Auth / OAuth / JWT; a first-class concern in these applications.

AI AGENT SERVICES

- LangGraph our agent services are built on it: graphs, state, and checkpointing.



LangChain or a comparable orchestration library transfers; what matters is having built something agentic, not just called a model.
- Python with FastAPI typed, async, Pydantic models; enough to extend and debug a service, not necessarily own the whole stack.
- LLM application basics prompts, tool calling, structured output, and handling cases where the model returns something unusable.
- AWS Bedrock we call Claude models through it; Anthropic or OpenAI API experience transfers.

TESTING DELIVERY

- Playwright (or Cypress / Selenium) writing both API and end-to-end tests, including per-role permission checks.
- Git at team scale branches, rebasing, PR review, and resolving real conflicts.
- GitHub Actions enough to read a workflow and diagnose a failure.
- Docker Compose bring up and debug a local stack (up, logs, exec); no Dockerfile authoring needed.

WORKING WITH CLAUDE

- Has used an AI coding agent on real work Claude Code or similar.
- Reviews what it writes can describe a time it was confidently wrong and how they caught it.
- Scopes and contextualizes tasks rather than asking for whole features in one go.
- Owns the output can explain and defend every line they submit.

NICE TO HAVE

- AngularJS 1.x our Lit components mount inside AngularJS portal widgets; optional, but rare and hard to teach, so a real bonus. (Not the same as modern Angular.)
- ServiceNow scoped apps, Service Portal, Glide APIs, Fluent SDK.
- Python for deployment and provisioning scripts.
- Postgres, Redis, OpenSearch; RAG or agent-evaluation experience.
