Mid Level Full Stack Developer Role

Role Overview

As a Mid Level Full Stack Developer, you will be responsible for designing, coding, and maintaining both front-end and back-end components of web applications. Your day-to-day work directly impacts product functionality and business efficiency, ensuring that client deliverables meet high standards of performance and security.

Detailed Responsibilities

• Develop and maintain production web systems using TypeScript, React, and Node.js.
• Build and optimize database schemas using PostgreSQL.
• Integrate AI development tools like Codex or Claude Code into real-world codebases.
• Manage cloud infrastructure on AWS and configure CI/CD pipelines via GitHub Actions.
• Ensure applications meet security fundamentals and accessibility standards like WCAG.
• Migrate legacy applications to modern web platforms when required.

Day-to-Day Workflow

Your typical day begins with a team sync to review progress on current sprint goals. You will spend the majority of your time coding in a local environment, utilizing AI assistants to accelerate development tasks. Afternoon hours often involve code reviews, debugging database issues, and updating documentation. The workflow is agile, with regular participation in Scrum ceremonies to align on project milestones.

Tools and Technologies

The tech stack is modern and cloud-centric. You will primarily work with TypeScript, React, and Node.js for application logic. Database management relies on PostgreSQL, often hosted on AWS RDS. Infrastructure is managed through AWS, with deployment automation handled by GitHub Actions. AI literacy is a key requirement, with hands-on experience in tools like Codex and Claude Code expected.

Skills and Requirements

Technical Skills

Candidates must possess 3+ years of experience building production web systems. Proficiency in the core stack (TypeScript, React, Node.js, PostgreSQL) is non-negotiable. You should also demonstrate strong understanding of cloud infrastructure (AWS) and CI/CD pipelines. Familiarity with security fundamentals and accessibility depth (WCAG/508) is highly valued, even if not strictly required for entry.

Soft Skills

Instant Serve LLC prioritizes curiosity and initiative over perfection. Effective communication is critical for remote collaboration, especially when explaining complex technical concepts to non-technical stakeholders. Problem-solving skills must be robust, allowing you to troubleshoot schema, data, and deployment issues across environments independently.

Experience Expectations

A Bachelor’s degree in Computer Science or a related field is typically expected, though equivalent professional experience may substitute. You should have a portfolio showcasing 3+ years of full-stack development, with specific examples of modernizing legacy systems or working in regulated environments if possible. Agentic AI literacy—using AI tools on real codebases—is a distinct requirement for this role.

Salary and Benefits

Based on market data for similar Mid-Level Full Stack roles in the US remote sector, the estimated pay range is $110,000 to $135,000 per year. Some comparable roles in the region offer up to $125,000, depending on specific experience levels.
