Engineering Job Challenge

Discord | Website | Docs

Welcome to the Engineering Job Challenge! 🚀

This is a practical exercise designed to give you a feel for the kind of problems we solve at JetKVM. Pick one or more challenges, implement your solution in the relevant repos, and send us your patch sets. Your submission should demonstrate not only that it works, but also clean code, thoughtful design, and a good developer experience.

Important

Deadline for this job challenge is 23 September, 2025 - 23:59 UTC.

How to Participate

1. Clone the repos you need for the challenge (e.g. kvm, api). Keep private until deadline.
2. Implement challenges using the pre-defined challenge branch name

Once you're ready with all the challenges you wanted to implement:

1. Create a patchset for each challenge & repo

git fetch --all --tags
git format-patch \
--base=challenge-base \
challenge-base...<your-challenge-branch> \
-o ~/jetkvm-challenges/<your-challenge-branch>/<repo-name>

2. Package your work

Zip the whole ~/jetkvm-challenges directory. It should looks something like:

jetkvm-challenges/
  automated-e2e-test-suite/
    kvm/
      0001-add-tests.patch
    api/
      0001-new-endpoint.patch
  h265/
    kvm/
      0001-add-h265-support.patch

3. Email us the challenges
   • To: jobs [at] jetkvm [dot] com
   • Subject: JetKVM Engineering Job Challenge
   • Body: Anything you’d like us to know about your solution (e.g. notes, assumptions, trade-offs).
   • Attachment: One zip of the jetkvm-challenges directory with all the folders & .patch files in it.

FAQ

What to expect after submission

After the deadline on 23 September, 2025 (23:59 UTC), we’ll begin reviewing all submissions. To keep the process fair, we don’t provide feedback before the deadline - this way, every challenge is considered under the same conditions.

Reviews are done by our team, not by an automated system. We look carefully at each submission, paying attention both to the solution itself and to how it was approached.

Once the review is complete, we’ll get back to you directly with the outcome - whether or not you move forward.

Use of AI Tools

You are welcome to use AI tools while working on this challenge. This reflects how we work day-to-day at JetKVM: AI can speed things up, but it’s not a substitute for thoughtful engineering. What matters is that you fully understand the code you submit and could explain it if asked.
