Fullstack Engineer — Agentic Finance Solution
Job Title: Fullstack Engineer — Agentic Platform
Location: Noida( hybrid)
Experience: 7+ Years
Band: C1
Tech Stack: React / Angular · Node.js / Python · DynamoDB · AWS
Job Summary
We are looking for a skilled Fullstack Engineer to join our Digital and AI Solutions Engineering team, focused on building the user-facing layer and supporting backend APIs of a next-generation agentic platform for Finance and Accounting operations. You will design and deliver the interfaces and services that make complex AI-driven workflows accessible and actionable for human users — including human-in-the-loop worklists, exception management dashboards, tenant configuration tools, visual field mappers, and platform reporting.
This role sits at the intersection of enterprise UX and platform engineering. The screens you build are not cosmetic — they are where human reviewers approve payments, resolve invoice exceptions, configure ERP connectors, and track STP performance across clients. You will work in React or Angular on the frontend, Node.js or Python for backend APIs, and DynamoDB for data storage — all hosted on AWS. You will collaborate closely with AI engineers, backend platform engineers, and finance domain SMEs to deliver a product that is both technically solid and genuinely usable by finance operations teams.
Key Responsibilities
Build and maintain the Human-in-the-Loop (HITL) worklist UI — enabling finance reviewers to view queued tasks, inspect AI recommendations with supporting context, take approval or rejection decisions, add notes, and trigger escalations.
Develop the exception management dashboard — displaying real-time exception queues by type, aging bucket, and priority, with drill-down into individual exception detail, resolution history, and lifecycle status.
Design and implement RESTful APIs in Node.js or Python that serve the frontend, connecting UI interactions to the underlying platform services — orchestration, exception routing, approval workflows, audit trail, and notifications.
Design DynamoDB table schemas and access patterns for workflow state, tenant configuration, exception lifecycle records, and audit events — applying single-table design and GSI strategies for efficient querying.
Implement real-time UI updates using WebSockets or Server-Sent Events (SSE) to keep worklists, exception queues, and workflow status indicators live without full-page refreshes.
Integrate with AWS Cognito or equivalent for authentication and role-based access control — ensuring that tenant isolation, approver role restrictions, and audit trail requirements are enforced at the API layer.
Collaborate with AI and backend engineers to surface LLM-generated recommendations, confidence scores, and agent reasoning in the UI in a way that helps human reviewers make faster, better-informed decisions.
Ensure frontend observability — client-side error tracking, performance monitoring, and usage analytics — to support continuous improvement of the user experience across clients.
Required Skills
5+ years of fullstack engineering experience with strong proficiency in React or Angular and Node.js or Python.
Strong TypeScript skills across both frontend and backend.
Hands-on experience with AWS services — Lambda, API Gateway, DynamoDB, S3, CloudFront, Cognito, SQS, and SNS.
Experience building and consuming RESTful APIs — including API design, versioning, error handling, and pagination.
Proficiency with state management libraries — Redux or Redux Toolkit (React), NgRx (Angular), or equivalent.
Experience building form-heavy, data-intensive enterprise UIs — multi-step forms, configurable tables, inline editing, and complex validation.
Understanding of authentication and authorisation patterns — OAuth 2.0, JWT, session management, and role-based access control.
Strong grasp of web performance fundamentals — lazy loading, code splitting, caching strategies, and optimistic UI updates.
Experience building approval workflow or task management UIs where human decisions are a core interaction pattern — not just CRUD screens.
Preferred Qualifications
Solid experience with DynamoDB — data modelling, single-table design, Global Secondary Indexes (GSIs), and query optimisation for high-throughput read/write patterns.
Experience with data visualisation libraries (Recharts, Chart.js, D3, Highcharts, or Angular equivalents) for building operational dashboards with filtering and drill-down.
Experience with CI/CD pipelines and containerised deployments (Docker, AWS ECS or Lambda).
Prior experience building UIs for Finance and Accounting operations — invoice processing, payments, reconciliation, or similar workflows.
Exposure to drag-and-drop or visual mapping interfaces — field mappers, flow builders, or rule configurators — relevant to the integration layer configuration UI.
Familiarity with audit trail and compliance requirements in regulated environments — understanding how user actions in the UI must be logged and traceable.
Experience integrating frontend applications with LLM or AI services — surfacing model outputs, confidence indicators, and explanations in a user-friendly way.
Knowledge of accessibility standards (WCAG 2.1) for enterprise application UIs.
Familiarity with micro-frontend architecture for large-scale platform applications.
Experience with AWS Amplify or similar frameworks for accelerating frontend-to-AWS service connectivity.
Understanding of Finance and Accounting KPIs — STP rate, first-pass match rate, exception aging — and how operational teams use these metrics to manage performance.
