About SUpost:

SUpost is a friendly online marketplace for university students. Students use it to buy and sell textbooks and bikes, find housing and roommates, and connect with each other. Think of a university-only Facebook Marketplace that people actually trust. We've been running for more than ten years, we're profitable, and about 131,000 people use the site each year.

We're a small, relaxed team, and we're looking for junior developers who want to learn. You don't need to know everything already. You'll be learning alongside the founder, who will help you along the way.

What You'll Do:

  • Start small: get to know the codebase, fix little bugs, and tidy up pages
  • Build features in React and Next.js step by step as you get comfortable
  • Make pages look good and work well on phones
  • Ask lots of questions. That's part of the job!
  • Share ideas for making the site better for students

How We Work:

  • Training provided: we'll walk you through the code, the tools and how we ship
  • Patient code reviews: feedback is there to help you learn, not to judge you
  • No crunch: a steady pace, realistic tasks and flexible hours
  • Mistakes are okay: we'd rather you try something and learn than be afraid to touch the code
  • Fully remote: work from home, with some overlap with US time that we'll agree on together

You Might Be a Good Fit If You:

  • Have tried building something with React. A school project, a tutorial app or a personal project all count
  • Know some JavaScript, HTML and CSS
  • Are curious and enjoy figuring things out
  • Can communicate in English (it doesn't have to be perfect)

Bonus, but not required: Next.js, TypeScript, Tailwind CSS, Git, or an eye for design.

Fresh grads and self-taught developers are very welcome. Don't worry if you don't tick every box. If you're excited to learn, please apply!

What You Get:

  • Hands-on training and mentorship, with real experience on a live website
  • Your work used by thousands of students
  • A friendly team that has your back
  • Room to grow into a senior developer role over time

How to Apply:

Apply here on Kalibrr and include:

  1. A link to anything you've built (GitHub, a portfolio, or a live site). Small or unfinished projects are totally fine!
  2. A sentence or two about what you'd like to learn

We read every application and look forward to meeting you. 😊

  • Some experience with React from school, tutorials or personal projects
  • Basic JavaScript, HTML and CSS
  • Able to communicate in English
  • Eager to learn and happy to ask questions
  • Able to overlap a few hours a day with US Pacific time
