Full-Stack Developer
Brady Martz
The Full-Stack Developer is responsible for designing, developing, testing, and maintaining internal software applications across frontend and backend systems. This role turns business requirements and written tickets into working functionality, collaborating across the development lifecycle to deliver reliable, scalable solutions that support firm operations. Develop, test, and maintain full-stack software solutions across Angular frontends and Symfony/PHP APIs, carrying features from written requirements through implementation and release. Read requirements and tickets critically, clarify scope and assumptions, and identify edge cases or missing details before development begins. Design and implement data changes, including Doctrine entities, relationships, migrations, API payloads, services, controllers, and the interfaces that consume them. Work within established application patterns and conventions, extending existing modules and adapting appropriately as the codebase evolves. Verify functionality before review by testing features in the running application, validating resulting data, and addressing scenarios not explicitly identified in the original requirements. Debug issues across the full request path, including browser behavior, network requests, APIs, application logs, backend services, client-side state, and user interfaces. Write and maintain meaningful unit and end-to-end test coverage and partner with Quality Assurance to ensure features are tested against clear acceptance criteria. Use AI development tools as a primary part of the development process while independently reviewing, validating, and taking accountability for all generated code and recommendations. Create clear, reviewable pull requests and participate in code reviews, documenting changes, assumptions, and intentionally excluded scope. Bachelor’s degree in software engineering, computer science, or a related field, or equivalent relevant professional experience. Demonstrated experience carrying software features from written requirements through development, testing, review, and production release. Ability to read and work with TypeScript and PHP and to evaluate whether code, including AI-generated code, is correct and appropriate for the application. Strong understanding of how modern web applications work, including authentication and permissions, APIs, object-relational mapping (ORM), client-side state management, and the connections between frontend and backend systems. Experience with a component-based frontend framework such as Angular, React, or Vue and comfort working across both frontend and backend application layers. Comfort with relational data, including reading schemas, understanding relationships and foreign keys, and using SQL to interpret application data and ORM-generated queries. Working knowledge of Git, command-line tools, Docker-based development environments, automated testing, and CI/CD practices. Strong debugging and problem-solving skills, with a methodical approach to reproducing, isolating, testing, and resolving issues. Self-directed, adaptable, and comfortable working through ambiguity while collaborating effectively with developers, QA, Product, and business stakeholders. Working comfort with AI development tools, or demonstrated aptitude and interest in making them a primary part of the development process while recognizing their limitations. Preferred experience with Angular, NgRx, PrimeNG, Symfony, Doctrine, Vitest, Angular Testing Library, Playwright, PHPUnit, Bitbucket Pipelines, or similar technologies; familiarity with professional services, accounting, or advisory environments is also beneficial.
