Role Overview :

As Senior QA Engineering Lead Frontend & Middleware , you will own the quality architecture, automation strategy, and testing standards for our React-based frontend platform and Node.js middle layer services.

This is a technical leadership role, not manual testing. You will design scalable test frameworks, automation pipelines, and workflow validation strategies while leading and mentoring a team of QA engineers.

You will partner closely with Frontend (React), Backend (Node.js), Data, and AI teams to ensure quality is built into the platform, not inspected after delivery.

What You Will Own :

- Quality strategy for React frontend and Node.js APIs

- Automation frameworks for UI, API, and workflow testing

- Frontend and middleware quality standards and best practices

- CI/CD quality gates and release readiness

- Technical leadership and growth of the QA engineering team

Key Responsibilities :

Quality Architecture & Strategy (Frontend & Middleware) :

- Define and own the quality engineering architecture for React and Node.js layers

- Establish standards for UI testing, API testing, and integration testing

- Design quality strategies aligned with modular frontend frameworks and service-based APIs

- Define test coverage models across frontend components, APIs, and workflows

- Act as the technical authority for quality decisions related to frontend and middleware

Frontend (React) Quality Engineering :

- Design and implement frontend automation frameworks for React applications

- Validate modular UI components, shared libraries, and design systems

- Ensure correctness of global configurations (theming, permissions, feature flags)

- Test complex, data-driven UI workflows and state transitions

- Partner with the React Lead to improve testability and frontend reliability

Middleware & API Testing (Node.js) :

- Design and own API testing frameworks for Node.js services

- Validate REST/GraphQL APIs, request/response contracts, and error handling

- Implement contract testing and integration testing patterns

- Ensure correctness of orchestration, async flows, and service interactions

- Validate security, authorization, and role-based access behaviors at the API layer

Workflow & End-to-End Validation :

- Design tests for end-to-end business workflows spanning UI ? API ? backend

- Validate process flows, state transitions, and failure scenarios

- Ensure reliability of user journeys across complex, multi-step workflows

- Identify quality risks early and partner with engineering teams to mitigate them

Automation, CI/CD & DevOps Integration :

- Embed automated tests into CI/CD pipelines

- Define quality gates for builds, deployments, and releases

- Drive shift-left testing practices across frontend and middleware teams

- Improve feedback loops between developers and QA engineers

- Balance test coverage with execution speed and maintainability

Team Leadership & Mentorship :

- Lead, mentor, and grow a team of QA engineers and interns

- Set standards for test design, automation, and code quality

- Conduct test architecture and automation reviews

- Coach QA engineers to think in terms of systems, workflows, and platforms

- Promote a shared ownership model for quality across engineering teams

Required Experience & Skills :

Core QA & Automation Expertise :

- 8 to 10+ years of experience in QA or Quality Engineering

- Strong hands-on experience testing React-based frontend applications

- Proven expertise in API testing for Node.js services

- Strong experience with test automation frameworks (UI and API)

- Experience validating complex workflows and user journeys

Frontend & Middleware Understanding :

- Strong understanding of React architecture and component-based systems

- Experience testing modular frontend frameworks and shared UI libraries

- Solid understanding of Node.js backend services and API design

- Familiarity with microservices, async APIs, and event-driven patterns

Platform & Systems Thinking :

- Experience designing QA strategies for SaaS platforms, not just applications

- Ability to reason about end-to-end systems and failure scenarios

- Experience working in CI/CD-driven development environments

- Strong understanding of integration points between UI and APIs

Leadership & Collaboration :

- Proven experience leading or guiding QA teams

- Strong mentoring and coaching skills

- Ability to influence frontend and backend teams on quality practices

- Comfortable collaborating with Product, UX, and Engineering leaders

- Clear communicator across technical and non-technical audiences

Why This Role Is Critical :

- You ensure frontend and API quality as the platform scales

- You protect user trust across complex, data-driven workflows

- You elevate QA from execution to engineering leadership

- You enable faster delivery without sacrificing reliability

- You shape how quality is designed into the product

Ideal Candidate Profile :

This role is ideal for someone who :

- Has built frontend and API automation frameworks from scratch

- Understands React and Node.js deeply enough to influence design

- Thinks about quality at the workflow and platform level

- Enjoys mentoring teams and setting technical standards

- Wants to own quality as a core engineering capability
