The successful candidate will build production applications while establishing reusable engineering patterns, standards and platform capabilities that can be adopted across multiple project teams.\n\nThe individual will be expected to operate across the full application lifecycle, spanning React/TypeScript front-end engineering, Python backend services, API integration, enterprise authentication and authorization, Snowflake connectivity, automated testing, CI/CD, cloud deployment, security and production observability.\n\nThis is not a traditional people-management position or a pure front-end role. It requires a senior engineer who can remain hands-on while acting as a technical SME and design authority across multiple initiatives.\n\nKey Responsibilities\n\nFront-End Engineering\n\nDesign and build scalable, production-grade applications using React and TypeScript. \nEstablish component-driven UI architectures supporting reusable components, modular development and consistent user experiences. \nImplement robust approaches for routing, client and server state, asynchronous data retrieval, error/loading states and caching. \nBuild responsive, accessible applications supporting desktop and tablet experiences. \nDevelop data-intensive interfaces using visualization libraries such as Highcharts, ECharts, D3 or equivalent. \nOptimize application performance through appropriate use of lazy loading, code splitting, memoization, virtualization, pagination and caching. \nEstablish reusable design systems, component libraries, and Figma-to-code patterns across multiple applications. \nApply appropriate accessibility standards such as WCAG 2.1 AA. \n\nBackend & API Engineering\n\nDesign, develop and maintain backend services using Python with Flask and/or FastAPI. \nDesign well-structured REST APIs covering contracts, schema validation, versioning, pagination, standardized error handling and API documentation. \nOwn frontend/backend integration end to end, including API contracts, schema evolution and backward compatibility. \nIntegrate applications securely with enterprise platforms and cloud data services. \nDevelop performant data-access patterns for Snowflake and other cloud data platforms, with appropriate consideration for connection management, query performance and caching. \nMaintain appropriate separation between presentation, service/business logic and data-access layers. \n\nSecurity & Enterprise Engineering\n\nApply secure-by-design engineering principles throughout the application lifecycle. \nImplement enterprise authentication patterns utilizing SSO, OAuth2/OIDC and/or SAML. \nDesign application authorization using RBAC and entitlement-based access controls, ensuring protected resources and data permissions are enforced server-side or at the appropriate data/service layer. \nApply OWASP-aligned secure coding practices covering injection, XSS, CSRF, authentication/session risks and dependency vulnerabilities. \nEnsure credentials, tokens and secrets are managed securely and never exposed within client-side code. \nParticipate in SAST/SCA/DAST scanning, dependency management, vulnerability remediation and application-security reviews. \nImplement appropriate audit logging and access traceability for enterprise applications. \n\nCloud, DevOps & Production Engineering\n\nContainerize web applications and backend services using Docker. \nBuild and maintain automated CI/CD pipelines using GitHub Actions, GitLab CI, Azure DevOps or comparable platforms. \nDeploy and support applications on AWS/cloud-based container environments. \nImplement structured logging, application/API metrics, performance monitoring and operational dashboards. \nUse observability platforms such as Grafana, CloudWatch, AppDynamics, Datadog or equivalent. \nDiagnose production issues, perform root-cause analysis and implement preventative improvements. \nEstablish appropriate environment configuration, dependency management and release/versioning practices. \n\nQuality Engineering\n\nEstablish automated testing across unit, component, integration, API and end-to-end layers. \nUse modern test frameworks such as React Testing Library, Jest/Vitest and Playwright/Cypress or equivalent. \nEstablish API and frontend/backend contract-testing practices. \nDefine practical code-quality and test-coverage expectations. \nPromote automated quality checks within CI/CD pipelines. \n\nArchitecture, SME & Technical Leadership\n\nServe as the React and full-stack engineering SME across multiple analytics initiatives. \nDefine and maintain reusable reference architectures, application scaffolding, shared components and engineering standards. \nLead technical design and code reviews across internal and partner/vendor engineering teams. \nEvaluate architectural options and make pragmatic decisions covering scalability, maintainability, security, performance and delivery complexity. \nSet standards covering coding, branching, testing, security, accessibility, documentation and definition of done. \nGuide teams on technical feasibility, estimates, engineering trade-offs and build-versus-buy decisions. \nIdentify and manage technical debt, modernization opportunities and dependency/lifecycle risks. \nMentor engineers through design reviews, pairing, reference implementations and technical documentation. \nInfluence teams without direct reporting authority and drive adoption of common engineering standards. \nCommunicate technical decisions, risks and recommendations effectively to architecture, security, product and senior business stakeholders. \n\nRequired Qualifications\n\nBachelor's degree in Computer Science, Engineering or related field required\n9–12 years of professional software engineering experience. \nApproximately 5+ years of substantial hands-on experience with React and modern JavaScript/TypeScript development. \nStrong knowledge of React architecture, hooks, component design, routing, state/data management and frontend performance. \nDemonstrated experience designing and developing backend APIs, preferably using Python/FastAPI. \nProven ownership of end-to-end full-stack applications from architecture and development through testing, deployment and production support. \nStrong understanding of REST API architecture and frontend/backend integration patterns. \nStrong SQL skills and experience integrating applications with relational databases or cloud data platforms. \nExperience implementing authentication and authorization for enterprise applications. \nPractical understanding of application security and OWASP-aligned secure development practices. \nHands-on experience with Git, CI/CD, Docker and cloud deployment. \nStrong automated-testing discipline across frontend and backend services. \nDemonstrated ability to troubleshoot application performance and production issues. \nExperience conducting architecture/design and code reviews. \nProven ability to establish engineering standards and influence multiple engineering teams. \nStrong communication skills with the ability to translate complex technical topics for non-technical stakeholders. \nExperience working within Agile delivery environments. \n\nWork Location Assignment: Hybrid\n\nPfizer is an equal opportunity employer and complies with all applicable equal employment opportunity legislation in each jurisdiction in which it operates.\n\nTo learn more about acceptable and prohibited uses of AI
