Senior Full Stack Software Engineer

Requirements:

• At least six years of professional software engineering experience with increasing responsibility for production web applications; seven to ten or more years is preferred.
• Strong hands-on experience supporting, maintaining, and refactoring production applications built with PHP and MySQL.
• Strong JavaScript or TypeScript skills using React or a comparable frontend framework, plus solid HTML and CSS fundamentals.
• Strong relational database design and SQL skills.
• Experience designing or consuming APIs and integrating applications with external services.
• Experience with automated testing, Git-based delivery workflows, code review, and secure development fundamentals.
• Working knowledge of CI/CD practices, Linux-based application environments, and application security; this is not a dedicated DevOps, system administration, or cybersecurity role.
• Practical experience using AI-assisted development tools for code analysis, implementation, testing, documentation, or review, with effective human oversight.
• Ability to diagnose production issues across application, database, and integration layers, take technical ownership, and deliver with limited supervision.
• Strong collaboration, communication, and mentoring skills, including explaining technical decisions to nontechnical stakeholders.
• Preferred: Experience leading a PHP-to-Node.js migration, modernizing legacy applications, or completing a comparable platform transition.
• Preferred: Experience establishing unit, integration, end-to-end, or characterization tests for an existing application.
• Preferred: Experience with one or more of Next.js, Prisma, PostgreSQL, Tailwind CSS, or reusable component-based design systems.
• Preferred: Experience with delivery and operations capabilities such as GitHub Actions, containers, infrastructure as code, advanced observability, or security-scanning platforms.
• Preferred: Experience with authentication, authorization, multifactor authentication, multi-tenant application design, or regulated business data.
• Preferred: Experience with Antigravity or another AI coding assistant, agentic development tool, or automated code review platform.
• Preferred: Experience administering or developing WordPress websites.
• Preferred: Bachelors degree in computer science, software engineering, information systems, or a related field, or equivalent practical experience.

Responsibilities:

• Take ownership of maintaining and improving existing PHP and MySQL applications, including resolving defects, tuning performance, making controlled feature changes, and analyzing code, databases, integrations, scheduled processes, and user workflows.
• Modernize application capabilities incrementally using a React and TypeScript stack, including technologies such as Next.js, Prisma, PostgreSQL, and Tailwind CSS.
• Design maintainable application components, responsive and accessible interfaces, APIs, data models, migration routines, and integration patterns.
• Plan and carry out database changes and migrations, including suitable validation, reconciliation, backup, recovery, and rollback procedures.
• Develop automated tests for critical workflows and deliver small, testable changes using regression testing, feature flags, and production observability where appropriate.
• Improve CI/CD workflows with the development team by incorporating automated builds and tests, code-quality and security checks, pull-request reviews, release controls, and dependable deployment and rollback procedures.
• Investigate production issues using logs, monitoring data, and standard Linux command-line tools, coordinating with teammates on environment or infrastructure concerns.
• Use AI coding assistants and development agents to analyze legacy code, implement changes, generate tests and documentation, review code, and diagnose defects while applying human validation and appropriate data and security controls.
• Apply secure development practices for authentication, authorization, input validation, data protection, secrets, dependencies, audit logging, and common web application risks.
• Document architecture, setup, deployment, interfaces, database decisions, support procedures, and known technical debt.
• Work with business leaders and users to clarify needs, assess tradeoffs, estimate work, and deliver practical solutions.
• Collaborate with and mentor the broader development team on architecture, technical standards, release coordination, knowledge sharing, and complex application or production issues.
