Sr Manager, Full-Stack Engineering

Overview

Hands-on Full-Stack Engineering and React SME role providing technical leadership for modern web-based analytics applications across the Analytics Gateway portfolio, combining hands-on engineering, solution architecture, and technical leadership.

What you'll do

• Design and build scalable, production-grade applications using React and TypeScript.
• Establish component-driven UI architectures supporting reusable components, modular development and consistent user experiences.
• Implement robust approaches for routing, client and server state, asynchronous data retrieval, error/loading states and caching.
• Build responsive, accessible applications supporting desktop and tablet experiences.
• Develop data-intensive interfaces using visualization libraries such as Highcharts, ECharts, D3 or equivalent.
• Optimize application performance through appropriate use of lazy loading, code splitting, memoization, virtualization, pagination and caching.
• Establish reusable design systems, component libraries, and Figma-to-code patterns across multiple applications.
• Apply appropriate accessibility standards such as WCAG 2.1 AA.
• Design, develop and maintain backend services using Python with Flask and/or FastAPI.
• Design well-structured REST APIs covering contracts, schema validation, versioning, pagination, standardized error handling and API documentation.
• Own frontend/backend integration end to end, including API contracts, schema evolution and backward compatibility.
• Integrate applications securely with enterprise platforms and cloud data services.
• Develop performant data-access patterns for Snowflake and other cloud data platforms, with appropriate consideration for connection management, query performance and caching.
• Maintain appropriate separation between presentation, service/business logic and data-access layers.
• Apply secure-by-design engineering principles throughout the application lifecycle.
• Implement enterprise authentication patterns utilizing SSO, OAuth2/OIDC and/or SAML.
• Design 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.
• Apply OWASP-aligned secure coding practices covering injection, XSS, CSRF, authentication/session risks and dependency vulnerabilities.
• Ensure credentials, tokens and secrets are managed securely and never exposed within client-side code.
• Participate in SAST/SCA/DAST scanning, dependency management, vulnerability remediation and application-security reviews.
• Implement appropriate audit logging and access traceability for enterprise applications.
• Containerize web applications and backend services using Docker.
• Build and maintain automated CI/CD pipelines using GitHub Actions, GitLab CI, Azure DevOps or comparable platforms.
• Deploy and support applications on AWS/cloud-based container environments.
• Implement structured logging, application/API metrics, performance monitoring and operational dashboards.
• Use observability platforms such as Grafana, CloudWatch, AppDynamics, Datadog or equivalent.
• Diagnose production issues, perform root-cause analysis and implement preventative improvements.
• Establish appropriate environment configuration, dependency management and release/versioning practices.
• Establish automated testing across unit, component, integration, API and end-to-end layers.
• Use modern test frameworks such as React Testing Library, Jest/Vitest and Playwright/Cypress or equivalent.
• Establish API and frontend/backend contract-testing practices.
• Define practical code-quality and test-coverage expectations.
• Promote automated quality checks within CI/CD pipelines.
• Serve as the React and full-stack engineering SME across multiple analytics initiatives.
• Define and maintain reusable reference architectures, application scaffolding, shared components and engineering standards.
• Lead technical design and code reviews across internal and partner/vendor engineering teams.
• Evaluate architectural options and make pragmatic decisions covering scalability, maintainability, security, performance and delivery complexity.
• Set standards covering coding, branching, testing, security, accessibility, documentation and definition of done.
• Guide teams on technical feasibility, estimates, engineering trade-offs and build-versus-buy decisions.
• Identify and manage technical debt, modernization opportunities and dependency/lifecycle risks.
• Mentor engineers through design reviews, pairing, reference implementations and technical documentation.
• Influence teams without direct reporting authority and drive adoption of common engineering standards.
• Communicate technical decisions, risks and recommendations effectively to architecture, security, product and senior business stakeholders.

What you'll need

• Bachelor's degree in Computer Science, Engineering or related field.
• 9–12 years of professional software engineering experience.
• Approximately 5+ years of substantial hands-on experience with React and modern JavaScript/TypeScript development.
• Strong knowledge of React architecture, hooks, component design, routing, state/data management and frontend performance.
• Demonstrated experience designing and developing backend APIs, preferably using Python/FastAPI.
• Proven ownership of end-to-end full-stack applications from architecture and development through testing, deployment and production support.
• Strong understanding of REST API architecture and frontend/backend integration patterns.
• Strong SQL skills and experience integrating applications with relational databases or cloud data platforms.
• Experience implementing authentication and authorization for enterprise applications.
• Practical understanding of application security and OWASP-aligned secure development practices.
• Hands-on experience with Git, CI/CD, Docker and cloud deployment.
• Strong automated-testing discipline across frontend and backend services.
• Demonstrated ability to troubleshoot application performance and production issues.
• Experience conducting architecture/design and code reviews.
• Proven ability to establish engineering standards and influence multiple engineering teams.
• Strong communication skills with the ability to translate complex technical topics for non-technical stakeholders.
• Experience working within Agile delivery environments.
