The main difference between a Sr Frontend Developer and a Frontend Developer lies in experience, responsibilities, and leadership.

Both roles require strong JavaScript, HTML, and CSS skills, but senior roles demand more experience and strategic input.

What is a Sr Frontend Developer?

Sr Frontend Developers are experienced software engineers who specialize in building and optimizing the user interfaces of web applications. They are responsible for translating design mockups into interactive, responsive, and accessible web pages using technologies like HTML, CSS, and JavaScript frameworks (such as React, Angular, or Vue). In addition to coding, Sr Frontend Developers often lead technical decisions, mentor junior developers, and collaborate closely with designers and backend engineers to deliver high-quality user experiences. Their expertise ensures that web applications are visually appealing, performant, and user-friendly.

What are some common challenges faced by Sr Frontend Developers when working on cross-functional teams?

Sr Frontend Developers often collaborate closely with backend engineers, UX/UI designers, and product managers. A common challenge in these environments is ensuring clear communication of technical requirements and design expectations to avoid misunderstandings that can lead to rework. Balancing user experience with technical feasibility is another frequent hurdle, especially when negotiating priorities between design vision and performance constraints. Effective Sr Frontend Developers proactively bridge gaps through strong documentation, regular alignment meetings, and by advocating for best practices in both development and design.

What are the key skills and qualifications needed to thrive as a Sr Frontend Developer?

To thrive as a Sr Frontend Developer, you need deep expertise in HTML, CSS, JavaScript, and modern front-end frameworks like React or Angular, usually backed by a degree in computer science or equivalent experience. Advanced knowledge of tools such as Git, Webpack, RESTful APIs, and proficiency with testing frameworks is typically required. Outstanding problem-solving abilities, strong collaboration, and effective communication set top performers apart in this role. These skills ensure the delivery of high-quality, user-friendly interfaces and seamless teamwork in fast-paced development environments.

We are working to empower the workforces of the future; if you're as passionate about transforming workplaces with the power of Data & AI as we are, we'd love to hear from you!
About the Role
The onshore Senior Front-End Engineer leads React UI architecture and build quality for the platform, directing a pod of offshore front-end engineers while remaining hands-on in code review, component library ownership, and sprint delivery. In this role, you will serve as the technical authority on all frontend decisions, from design system implementation through role-based access control (RBAC) patterns, API integration, and CI/CD pipeline compliance. You will collaborate closely with the onshore Solution Architect, UX/Product Designer, and Sr. Back-End Engineer to ensure the frontend is production-ready and demo-ready every two weeks.
This role is work-from-home (remote) though must be able to commute to client offices in Falls Church, VA as needed (estimated every 2 weeks). This is a full-time W2 employment role with befits. Please note that this role is tied to a client contract and is structured as an initial 9-month position. Opportunities for extension or long-term placement are highly likely based on client renewal and project performance.
Responsibilities
As the Senior Front-End Engineer, you will set the technical direction for the frontend ecosystem, mentor engineering talent, and deliver robust software. Your key responsibilities include:
  • Architecture & Leadership: Lead React frontend architecture, defining component structure, state management patterns, and design system implementation across all process flow UIs. Direct and oversee a pod of offshore front-end engineers by assigning work, conducting code reviews, and ensuring production-ready output.
  • Component Systems & UI Development: Build and own the shared component library used across all role-based process flow UIs. Collaborate with the Lead UX/Product Designer to translate Figma wireframes into high-fidelity, accessible React implementations meeting WCAG 2.2 A standards.
  • API Integration & Access Control: Implement data reads and write operations from React to the backend REST API layer (via Azure APIM), ensuring the frontend does not call the database or ERP system directly. Implement RBAC in the UI aligned with SSO federation via Azure Entra ID.
  • Quality, Pipeline & Security Compliance: Own CI/CD pipeline compliance for frontend code, ensuring all commits pass Veracode SAST + SCA security scanning prior to merging. Resolve and triage frontend defects during SIT, UAT, and post-launch hypercare within agreed SLA windows.
  • Stakeholder Demos & Delivery: Lead bi-weekly sprint demos with stakeholders, ensuring all frontend work is demo-ready on schedule. Conduct knowledge transfer to the client team ahead of the support handoff.

Required Skills & Experience
  • 6-8+ years of front-end development experience, with at least 4 years focused in React (functional components, hooks, context API, performance optimization).
  • Demonstrable experience leading or directing offshore front-end engineering teams.
  • Proven experience working from Figma wireframes and collaborating closely with UX/UI designers.
  • Experience using AI coding assistants (e.g., Claude Code, GitHub Copilot, Cursor) for pair programming, code generation, architecture documentation, and code review (AI-assisted development is standard on this engagement).
  • Familiarity with RBAC patterns and SSO integration (Azure Entra ID / OAuth 2.0 preferred).
  • Experience with automated UI testing frameworks such as Storybook, Playwright, or similar.
  • Strong verbal and written communication skills with the proven ability to lead sprint demos, conduct code reviews with offshore teams, and articulate technical decisions to non-technical stakeholders.

Preferred Qualifications
  • Prior experience building enterprise financial or ERP applications.
  • Experience building and owning shared component libraries and design systems for enterprise web applications.
  • Experience consuming REST APIs via Azure APIM or equivalent API gateways.
  • Proficiency with Azure DevOps CI/CD pipelines and security-gated build processes (Veracode or similar SAST tools).
  • Familiarity with Azure App Service hosting and deployment patterns.
  • Familiarity with RTK Query, Material UI, and React Router.
