Summary

Capstone IT is helping our client find a Senior Front-End Developer who will design, build, and maintain enterprise-grade user interfaces for mission-critical applications. This person will own front-end development across the full SDLC — from architecture and component design to testing and deployment. They will work embedded on an Agile team, collaborate closely with back-end engineers, and be expected to produce clean, testable, and performant React code on day one.

 

Top 4 Skills

• React (5+ years professional experience)
• TypeScript & JavaScript (ES6+)
• HTML5 & CSS3 — semantic, accessible markup and styling
• MUI (Material UI) component library

 

Responsibilities

• Develop and maintain mission-critical front-end user interfaces using React and TypeScript
• Build modular, reusable components and shared libraries
• Write efficient, secure, and well-documented JavaScript/TypeScript code
• Investigate, debug, and resolve software defects
• Participate in Agile ceremonies and collaborate with cross-functional teams
• Prepare and execute releases of software components
• Establish and uphold front-end technical standards and best practices
• Stay current with evolving front-end technologies and contribute to continuous improvement

 

Qualifications

Required:

• BS or equivalent degree in Computer Science or related field
• 6+ years of professional UI/UX development experience
• 3+ years of professional React experience
• Working knowledge of Next.js
• Proficiency in TypeScript, JavaScript, HTML5, and CSS3
• Experience with MUI (Material UI) component library
• Ability to write efficient, secure, and maintainable JavaScript code
• Experience building reusable components and libraries
• Experience with Jest for unit testing
• Proficiency with Git for version control

 

Nice to Have:

• Experience with Spring Boot
• Familiarity with Kafka
• Knowledge of MongoDB
• Experience with Azure DevOps
• Familiarity with Domain-Driven Design (DDD) concepts
• Knowledge of microservices architecture
• Hands-on experience with Gradle

 

2. Role Context – This Company

Within this organization, the Senior Front-End Developer sits on an established software team building and maintaining mission-critical applications — likely internal platforms or customer-facing systems that must perform reliably under real operational load. The role operates across the full SDLC, meaning this person is not handed tickets in isolation; they are expected to contribute to design decisions, set technical standards, and guide quality.

 

The team follows Agile practices, so the developer will work in sprint cycles, participate in planning and retrospectives, and collaborate closely with back-end engineers (who may be working in Spring Boot given the nice-to-have requirements). The presence of Kafka and Microservices as preferred skills suggests a distributed, event-driven architecture — this is not a small CRUD app shop. The inclusion of Azure DevOps points to an established CI/CD pipeline, and the expectation of Gradle familiarity indicates a Java-adjacent build environment on the back end.

 

The hard on-site requirement (5 days/week, Glen Allen) and the emphasis on local candidates strongly suggests this team values in-person collaboration, likely due to the mission-critical nature of the systems or security and compliance requirements in their industry.

 

Please send your resume and salary requirements for immediate consideration!
