A Senior Full Stack Software Developer needs advanced proficiency in both front-end and back-end programming languages, strong problem-solving skills, and several years of relevant software development experience. Familiarity with frameworks like React or Angular, back-end technologies such as Node.js or Django, and experience with cloud platforms, CI/CD tools, and version control systems like Git are typically required. Excellent communication, teamwork, and leadership abilities help developers collaborate effectively and mentor junior team members. These skills are crucial for designing robust, scalable applications and leading complex projects to successful completion.

What types of projects and technologies can a Senior Full Stack Software Developer expect to work on, and how does the team typically collaborate?

As a Senior Full Stack Software Developer, you can expect to work on a diverse range of projects such as developing scalable web applications, integrating APIs, and optimizing system performance. The tech stack often includes front-end frameworks like React or Angular, back-end environments such as Node.js, Python, or Java, and databases like PostgreSQL or MongoDB. Collaboration is highly cross-functional—you’ll regularly coordinate with product managers, UX/UI designers, QA engineers, and other developers through agile methodologies, code reviews, and sprint planning sessions. This role offers opportunities to mentor junior developers, influence architectural decisions, and contribute to continuous process improvement.

What is a Senior Full Stack Software Developer?

A Senior Full Stack Software Developer is an experienced professional who designs, develops, and maintains both the front-end and back-end components of web applications. They are proficient in multiple programming languages and frameworks, enabling them to work on the entire technology stack, from databases and servers to user interfaces. In addition to coding, they often lead projects, mentor junior developers, and help architect scalable solutions that meet business needs. Their role requires strong problem-solving skills, a deep understanding of software development best practices, and the ability to collaborate with cross-functional teams.

While both roles involve software development, a Senior Full Stack Software Developer specializes in both front-end and back-end technologies, often taking on leadership responsibilities. A Software Engineer may focus on specific areas of software design and implementation, with less emphasis on full stack expertise. The roles overlap in skills and industry usage, but the senior developer typically has broader responsibilities and experience in full stack development.

Job Description
We are seeking a Senior Full Stack Developer (Frontend Emphasis, React.js) to build and sustain a mission critical command and control system for the Mobility Air Force. Your work will focus on developing modern single page applications using React.js and TypeScript, improving the user experience, and ensuring seamless integration with secure backend APIs. You will contribute across the stack, but your specialization will be front end architecture, UI performance, and maintainable component development.
You will collaborate closely with backend developers, guide UI design decisions, and mentor junior engineers within an Agile development environment.
What you will do
  • Design, implement, test, and deploy single page applications built with React.js and TypeScript.
  • Participate in front end architecture decisions, including state management, component structure, routing, and build configuration.
  • Develop reusable UI components, forms, and interactive views aligned with mission workflows.
  • Integrate React applications with Java and .NET backend services and RESTful APIs.
  • Build automated tests for the UI, including unit, integration, and end to end tests.
  • Ensure accessibility, responsiveness, and adherence to modern UI best practices.
  • Optimize performance through code splitting, lazy loading, and efficient rendering strategies.
  • Implement secure front end patterns, including dependency hygiene, API input validation, and token handling.
  • Review and refactor front end code to ensure maintainability and consistent patterns.
  • Mentor team members on React, TypeScript, testing strategies, and SPA architecture.

What we like to see
  • Strong proficiency with React.js, TypeScript, SPA architecture, and modern JavaScript tooling.
  • Experience with front end state management solutions such as Redux, Zustand, Recoil, or Context APIs.
  • Familiarity with build tools such as Webpack, Vite, Babel, or similar.
  • Experience consuming RESTful APIs and collaborating with backend developers to shape API contracts.
  • Understanding of accessibility and compliance standards common in government systems.
  • Experience deploying front end applications to AWS services such as S3, CloudFront, API Gateway, and Cognito.
  • Strong troubleshooting skills in UI performance, rendering, and cross browser compatibility.
  • Self directed with the ability to own features from concept to production.

You should be familiar with
  • HTML, CSS, JavaScript, and TypeScript.
  • React.js, React Router, and component-based architecture.
  • SPA security patterns for authenticated applications.
  • Modern front end testing frameworks such as Jest, React Testing Library, and Cypress.
  • RESTful API integration patterns.
  • Basic backend development in Java or .NET for full stack feature work.
  • Containerization concepts using Docker.
  • CI/CD practices for building, testing, and deploying front end assets.
  • Agile methodology.

Requirements
  • Minimum Experience: 5+ years of professional software development, including substantial front-end experience with React.js.
  • Experience owning front end architecture or major UI components in production SPA applications.
  • Bachelor's degree in Computer Science, Engineering, or related field, or equivalent experience.
  • Ability to obtain or maintain a government security clearance.
  • Prior DoD or federal experience is strongly preferred.

This position is eligible for remote work in the St. Louis area. However, the position requires a government security clearance, so candidates must be U.S. citizens and eligible for work without a visa sponsorship
