Mid Level Full Stack Developer (MERN/React Native) Role

Role Overview

In this role, you will be responsible for building and maintaining both frontend and backend components of web and mobile applications using the MERN stack (MongoDB, Express.js, React.js, Node.js) and React Native for cross-platform mobile development. You will collaborate with product managers, designers, and other engineers to deliver features that directly impact client success and user experience.

Your work will have a direct business impact, as you’ll be tasked with optimizing performance, reducing latency, and ensuring seamless integration between mobile and web platforms. This role is not just about coding—it’s about solving real problems for clients and contributing to the long-term scalability of their digital products.

Detailed Responsibilities

• Lead development of scalable web applications using MongoDB, Express.js, React.js, and Node.js
• Build and maintain React Native mobile apps for iOS and Android platforms
• Design and implement RESTful APIs and integrate third-party services like Stripe, Twilio, and Google OAuth
• Optimize applications for maximum performance, scalability, and security
• Conduct code reviews and provide feedback to improve team coding standards
• Mentor junior developers and foster professional growth within the team
• Collaborate with cross-functional teams to define product requirements and deliver features
• Act as a point of contact for clients, ensuring clear communication and alignment with goals

Day-to-Day Workflow

Your typical day starts with a stand-up meeting to review progress, blockers, and priorities. You’ll then dive into coding new features, debugging issues, or optimizing existing code. Mid-day often includes collaboration sessions with designers or product managers to refine UI/UX decisions or clarify requirements.

Afternoon hours are dedicated to code reviews, testing, and deployment tasks. You may also spend time documenting APIs, updating technical specs, or preparing demos for client reviews. The workflow is iterative, with frequent feedback loops ensuring alignment with client expectations.

Tools and Technologies

The tech stack centers on the MERN ecosystem and React Native. Key tools include:

• Frontend: React.js, TypeScript, Redux, React Native
• Backend: Node.js, Express.js, REST/GraphQL APIs
• Database: MongoDB, Mongoose
• Cloud & DevOps: AWS (EC2, S3, Lambda, API Gateway), Docker, CI/CD pipelines
• Testing: Jest, React Testing Library, Cypress
• Collaboration: Git, GitHub, Jira, Slack

Skills and Requirements

Technical Skills

You must have 2–4 years of experience in full-stack development with a focus on the MERN stack. Proficiency in MongoDB, Express.js, React.js, and Node.js is essential. Experience with AWS services (EC2, S3, Lambda) and DevOps practices like Docker and CI/CD is highly valued.

React Native expertise is critical for mobile development, including knowledge of native modules, performance optimization, and cross-platform compatibility. Familiarity with AI platforms, APIs, or machine learning services is an added advantage.

Soft Skills

TopFlight Apps prioritizes curiosity over perfection. You should demonstrate strong problem-solving abilities, attention to detail, and the ability to communicate technical concepts to non-technical stakeholders. Leadership skills are important, as you’ll mentor juniors and guide team performance.

Team collaboration, stakeholder management, and client-facing communication are also key. You must be able to manage expectations, deliver on time, and adapt to fast-paced startup or scale-up environments.

Experience Expectations

A Bachelor’s degree in Computer Science, Software Engineering, or a related field is commonly preferred. However, practical project experience often weighs more heavily than certifications.

Your portfolio should include live projects showcasing MERN and React Native development. Highlight features you led, performance improvements you made, and any client-facing work. GPA is not a primary factor—TopFlight Apps values initiative and real-world impact.

Salary and Benefits

While TopFlight Apps does not publish exact figures, market data for similar Mid Level MERN/React Native roles in the US suggests an estimated range of $85,000–$115,000 annually for full-time positions. For internships or contract roles, stipends typically range from $3,000–$6,000 per month, depending on experience and project scope.

Benefits include fully remote work, flexible hours, a learning budget for courses or certifications, and access to top-tier tools. Full-time conversion opportunities are common for high-performing interns, with clear pathways to senior engineering roles.
