Job Description

Posted on: September 26, 2026

A short-term project-based opportunity is now available for experienced Python and Full-Stack JavaScript/TypeScript developers who want to work on cutting-edge AI projects.

If you have strong experience with Python, JavaScript, TypeScript, Node.js, React, Vue.js, Angular, or NestJS, this could be an opportunity worth checking immediately.

The project is designed for developers who can combine strong software engineering fundamentals with modern AI development, evaluation, and model improvement workflows.

The expected start date is next week, making this a time-sensitive opportunity for qualified developers.

Project Details

This is a 1-month remote project-based contractor assignment focused on software development and AI technology.

The selected developer will work with teams developing advanced AI solutions for commercial and research applications.

The role combines traditional full-stack engineering with activities related to AI model evaluation, supervised fine-tuning, reinforcement learning, and AI response quality improvement.

The project requires developers who can write clean, maintainable code while also understanding how software engineering contributes to modern AI systems.

Key Project Areas Include

  • Python development
  • JavaScript and TypeScript development
  • Full-stack web application development
  • AI model evaluation
  • AI response assessment
  • Supervised Fine-Tuning (SFT)
  • Reinforcement Learning with Human Feedback (RLHF)
  • Dataset development
  • Code quality evaluation
  • Technical reasoning
  • Software testing
  • AI-assisted development

Registration / Application: APPLY

This makes the assignment particularly suitable for experienced software engineers, full-stack developers, Python developers, and AI-focused engineers.

What Will You Do?

The day-to-day responsibilities go beyond simply writing application code.

The selected developer will contribute to the development and improvement of AI systems while applying strong software engineering practices.

Develop High-Quality Software

You will design, develop, and maintain efficient and reusable code.

The Work Requires Attention To

  • Code readability
  • Maintainability
  • Scalability
  • Security
  • Stability
  • Testing
  • Reusability
  • Clear documentation

Developers should be comfortable working with modular architectures and production-quality web applications.

Work With Python and JavaScript/TypeScript

Strong knowledge of both Python and JavaScript/TypeScript is expected.

Depending on the project requirements, the technology stack may include:

  • Python
  • JavaScript
  • TypeScript
  • Node.js
  • NestJS
  • React
  • Vue.js
  • Angular

Experience across both backend and frontend development can be particularly valuable.

Evaluate AI Models

An important part of this project involves AI model evaluation, commonly known as Evals.

Developers may evaluate model responses against predefined criteria and determine how effectively an AI system handles different types of requests.

This Can Involve

  • Reviewing AI-generated responses
  • Ranking model outputs
  • Identifying weaknesses
  • Providing technical explanations
  • Creating evaluation rationales
  • Improving response quality
  • Comparing model performance

Strong analytical and reasoning skills are therefore important.

Contribute to SFT and RLHF

The project also involves AI training workflows such as Supervised Fine-Tuning (SFT) and Reinforcement Learning with Human Feedback (RLHF).

Activities may include helping create high-quality datasets, reviewing examples, improving responses, and collaborating with researchers or annotators.

Developers who already have experience working with LLMs, AI evaluation, or prompt engineering may have an advantage.

Required Technical Skills

Candidates should have strong practical software development experience.

The Core Technology Requirements Include

Python

Strong Python programming skills and experience writing clean, maintainable code.

JavaScript / TypeScript

Solid understanding of modern JavaScript and TypeScript development.

Node.js or NestJS

Experience building backend services using Node.js or NestJS.

Frontend Framework

Experience With At Least One Of

  • React
  • Vue.js
  • Angular

Docker

Knowledge of Docker is mandatory for this opportunity.

Experience building, testing, and deploying applications in containerized environments is highly relevant.

Software Engineering Experience

The ideal candidate should understand how to build scalable web applications rather than simply write isolated scripts.

Experience Should Include Areas Such As

  • Modular software development
  • Scalable architectures
  • Automated testing
  • Code reviews
  • Application security
  • Software stability
  • Maintainable codebases
  • Technical documentation

Candidates should also be comfortable participating in code reviews and providing constructive technical feedback.

AI Experience Is a Plus

Previous experience with Large Language Models can be beneficial.

Knowledge of tools such as ChatGPT and other LLM platforms may help candidates understand the AI-related components of the project.

Experience With

  • Prompt engineering
  • LLM evaluation
  • AI-generated code
  • AI response analysis
  • Dataset creation
  • Model training workflows

can strengthen an application.

However, the core focus remains strong software engineering ability across Python and JavaScript/TypeScript.

Who Should Apply?

This Project Could Be a Strong Fit For

  • Python Developers
  • Full-Stack Developers
  • JavaScript Developers
  • TypeScript Developers
  • Node.js Developers
  • NestJS Developers
  • React Developers
  • Vue.js Developers
  • Angular Developers
  • Software Engineers
  • AI Software Engineers
  • Backend Engineers
  • Developers with LLM experience

It may also be attractive to developers who want to gain exposure to the intersection of software engineering and AI model development.

Project-Based Remote Work

Unlike a conventional permanent position, this opportunity is structured as a short-term contractor assignment.

That Makes It Potentially Useful For Developers Who Prefer

  • Short-term technical projects
  • Flexible weekly commitments
  • Remote work
  • AI-related development experience
  • Contract-based opportunities
  • Exposure to different AI projects

The Assignment Offers Three Possible Weekly Commitment Levels

20 hours/week, 30 hours/week, or 40 hours/week.

Developers must be available for at least 4 hours per day, with a required 4-hour overlap with PST.

Compensation and Contract Details

The project offers a contractor-based engagement with the following key details:

  • Contract duration: 1 month
  • Expected start: Next week
  • Weekly commitment: 20, 30, or 40 hours
  • Minimum daily commitment: 4 hours
  • Timezone overlap: 4 hours with PST
  • Work arrangement: Fully remote
