Join us for the Open Source Hackathon, an exciting in-person event where coders unite to build cool projects!
About this Event

Developer? Love open source? And, open to considering a new job? JOIN US for this OSS support hackathon!
Support open source projects of your choice, win prizes, enjoy an amazing 2-day hackathon ✨

And, if you're open to new opportunities, get a very warm intro to the HL hiring managers and tech team.
ONLY For Developers!
PLEASE NOTE that your registration here does NOT guarantee attendance - we will review each application and let you know the outcome based on your answers.

Non-developers, people who are not open to learn about new opportunities, or who cannot legally work in the UK will not be allowed to attend.

An exclusive evening for Software Engineers to build and support an open source project/repository (or multiple projects/repos) OF YOUR CHOICE - while meeting great people, enjoying amazing food, and winning really cool prizes!

We'll be handing out prizes in multiple categories, incl. for most approved/merged contributions during the hackathon.

(if you're not feeling competitive, that's cool too - join us, get in the zone, lock-in, and just work on your OSS project of choice for a weekend without being disturbed)

We are NOT selling any services or products. Rather, this is our way to support open-source makers and contributors, while getting the best people together.

The event is run by developers, for developers.

ON US: atmosphere, drinks, snacks, dinners, breakfast, lunch, entertainment, prizes, and some great swag.

ON YOU: attendance, and a good vibe.

PLEASE NOTE

We hand-pick all the participants based on the tech stack, LinkedIn profile, and interests - to ensure there's a great group of people.
