Node TS + React TS + LLM Agents | Full Stack Developer Role

Role Overview

In this role, you will develop full-stack applications using TypeScript for both Node.js backends and React frontends, while simultaneously designing and integrating LLM agents that perform autonomous tasks. Your day-to-day involves writing clean, modular code, debugging agent behaviors, and ensuring seamless communication between the UI and AI services. The impact of your work is direct: you enable clients to automate complex workflows, reducing manual effort and increasing operational efficiency.

Detailed Responsibilities

• Build and maintain RESTful APIs using Node.js and TypeScript
• Develop responsive, interactive user interfaces with React and TypeScript
• Design and implement LLM agents using frameworks like LangChain or LlamaIndex
• Integrate AI models with existing databases and external services
• Optimize agent performance for latency, accuracy, and cost efficiency
• Collaborate with product teams to define agent capabilities and user flows
• Write unit and integration tests for both frontend and backend components

Day-to-Day Workflow

Your typical day starts with reviewing agent logs to identify failures or inefficiencies in the previous night's runs. You then spend 2–3 hours coding new features, such as a React dashboard that visualizes agent decisions or a Node endpoint that triggers a specific AI task. Midday includes a team sync to discuss progress, followed by focused time on debugging complex agent interactions or refining TypeScript type definitions. The afternoon often involves testing new model integrations and documenting changes for the engineering team.

Tools and Technologies

The tech stack centers on TypeScript across the entire application, with Node.js for server logic and React for the frontend. You will use AI frameworks like LangChain, LlamaIndex, or custom agent wrappers to interact with models from providers like OpenAI, Anthropic, or local LLMs. Development tools include VS Code, Git for version control, Docker for containerization, and Postman or curl for API testing. Cloud infrastructure likely involves AWS or Vercel for deployment, with monitoring via tools like Datadog or Sentry.

Skills and Requirements

Technical Skills

Proficiency in TypeScript is non-negotiable, with deep knowledge of its type system, interfaces, and async patterns. You must be experienced in building APIs with Node.js and creating dynamic UIs with React, including hooks, context, and state management libraries like Redux or Zustand. Familiarity with LLM agent architecture, prompt engineering, and model evaluation is essential. Additional skills include SQL/NoSQL database design, REST/GraphQL API consumption, and basic cloud deployment practices.

Soft Skills

Recruiters value curiosity, initiative, and the ability to communicate complex technical concepts clearly. You must be comfortable working independently in a remote setting while collaborating effectively with cross-functional teams. Problem-solving agility is critical, as agent behaviors can be unpredictable and require iterative debugging. Strong time management ensures you deliver features without compromising code quality or system stability.

Experience Expectations

S.A.G.A Corp targets rising juniors to seniors, so a graduate degree is not required. Instead, they prioritize a strong portfolio showcasing TypeScript projects, especially those involving AI or automation. Relevant experience includes internships at tech firms, personal projects with LLM integrations, or contributions to open-source AI libraries. A GPA is less important than demonstrated practical skills and the ability to ship production-ready code.

Salary and Benefits

For this specialized role, the estimated stipend or salary ranges from $60,000 to $90,000 annually for full-time positions, with internships offering $3,000–$5,000 per month. Benefits include full remote work, a learning budget for AI courses or conferences, and access to premium cloud credits for experimentation. The company often offers full-time conversion opportunities for high-performing interns, with potential for equity or performance bonuses in later stages.

S.A.G.A Corp Hiring Process

Step-by-Step Hiring Stages

1. Application: Submit resume, portfolio, and a brief statement on AI interest via their careers portal.
2. Screening: ATS filters for keywords like "TypeScript," "Node," "React," and "LLM"; portfolio review by engineering leads.
3. Assignment: Complete a take-home project building a small React/Node app with an integrated LLM agent.
4. Interviews: Two rounds: a technical deep-dive on code and architecture, followed by a behavioral chat with the hiring manager.
5. Offer: Negotiation of stipend/salary, start date, and remote work terms.

Application Timeline

Since the deadline is not mentioned, apply immediately to avoid missing the window. The typical process lasts 2–4 weeks, from application to offer, depending on candidate volume and assignment complexity. Early applicants often receive faster feedback, as the team prioritizes filling roles quickly for upcoming product launches.

Screening Methods

The ATS scans for specific keywords: "Node TS," "React TS," "LLM Agents," and "Full Stack Developer." Your portfolio must include at least one project demonstrating TypeScript usage and another showing AI integration. Recruiters look for clean code structure, meaningful comments, and evidence of testing. A generic resume without AI or TypeScript focus will likely be rejected.

Interview Preparation

Example Interview Questions

• "How would you design a React dashboard that displays real-time LLM agent decisions?"
• "Explain how you would optimize a Node.js endpoint that triggers multiple AI model calls."
• "What challenges have you faced when integrating LLM agents, and how did you resolve them?"
• "Describe a TypeScript feature you used to improve code safety in a recent project."

How to Answer

Use the STAR method (Situation, Task, Action, Result) to structure your responses, focusing on concrete examples from your portfolio. For technical questions, walk through your thought process step-by-step, explaining trade-offs in architecture or performance. For behavioral questions, highlight your curiosity and ability to learn quickly from failures.

What Recruiters Evaluate

Hiring managers assess your technical depth in TypeScript, your understanding of AI agent patterns, and your ability to communicate clearly. They also evaluate your problem-solving approach, code quality, and alignment with the company's curiosity-driven culture. Candidates who demonstrate initiative, such as proposing improvements to their assignment, stand out significantly.

How to Get Selected

Practical Tips

• Build a portfolio project that integrates a React frontend with a Node backend and an LLM agent.
• Use TypeScript strictly in all projects to demonstrate mastery of its type system.
• Write clear documentation for your code, showing you value maintainability.
• Network with current S.A.G.A Corp engineers on LinkedIn to learn about team priorities.

Common Mistakes to Avoid

• Submitting a resume without "TypeScript," "Node," or "LLM" keywords.
• Using JavaScript instead of TypeScript in your portfolio projects.
• Failing to explain your AI integration choices in the assignment.
• Ignoring the company's focus on curiosity and initiative in your application statement.

How to Stand Out

To differentiate yourself, create a live demo of your agent project and share it in your application. Mention specific AI frameworks you've used and explain why you chose them. Tailor your resume to highlight remote work experience and any AI-related coursework or certifications. Reaching out to a recruiter with a thoughtful question about the role can also signal genuine interest.
