About the Company
Oleovista Solutions Private Limited is a technology-focused company developing solutions across finance, trading, and Energy
Trading & Risk Management (ETRM). Our platforms support trading, financial operations, analytics, risk management,
integrations, and transaction processing.

Role Overview
We are looking for a Lead Frontend Developer / Technical Lead to take ownership of the frontend architecture and development of
a next-generation Treasury Management System within our ETRM platform.
This is a hands-on leadership role requiring strong expertise in React, TypeScript, JavaScript, frontend architecture, enterprise
data-intensive applications, API integration, security, performance, testing, and modern frontend engineering.
The successful candidate will lead technical design and implementation, establish development standards, mentor developers,
and take ownership of frontend delivery from requirements through production.
Experience in banking, fintech, payments, trading, brokerage, treasury, or other transaction-heavy financial systems is
strongly preferred. Direct ETRM/Treasury experience is not mandatory.

Key Responsibilities
• Frontend Architecture & Leadership: Own frontend architecture, component design, coding standards, design patterns,
technical decisions, code reviews, estimation, task planning, mentoring, and delivery; work closely with Product, UI/UX,
Backend, QA, DevOps, and Business teams.
• React Application Development: Build scalable, reusable, maintainable applications using React, TypeScript, and
JavaScript; develop reusable components, complex forms, dashboards, reports, transaction screens, and workflow
driven interfaces.
• Enterprise Data & Grids: Develop large, data-intensive enterprise interfaces with advanced data grids, server-side
filtering, sorting, pagination, searching, virtualization, inline/editable grids, bulk actions, row selection, validation,
and high-volume data handling.
• Treasury & Transaction Workflows: Build interfaces for transaction entry, approvals, workflow/state transitions,
exception handling, reconciliation, status tracking, and reporting, with appropriate frontend validation and user
controls.
• API, State & Real-Time Integration: Integrate with REST APIs and manage client/server state using Redux Toolkit,
Zustand, TanStack Query/React Query, or equivalent technologies; implement WebSockets/SSE for real-time data and
application updates where required.
• Security: Implement secure frontend practices covering authentication, authorization, RBAC, OAuth2/OIDC, JWT,
session/token management, secure API communication, XSS/CSRF protection, data handling, and OWASP
principles.
• Performance & User Experience: Optimize data-heavy applications through code splitting, lazy loading, caching,
memoization, virtualization, bundle optimization, rendering optimization, and efficient API usage; maintain strong
Core Web Vitals, responsiveness, accessibility, and browser compatibility.
• Testing & Quality: Establish automated unit, integration, and end-to-end testing using tools such as Jest/Vitest, React
Testing Library, and Playwright/Cypress; maintain high standards for code quality and reliability.
• Cloud, CI/CD & Production: Work with Git, Docker, CI/CD, GitHub Actions/Azure DevOps, and Azure/AWS; support
frontend monitoring, error tracking, logging, production troubleshooting, releases, and operational stability.
