Low-Latency Developer for Upbit Announcement WebSocket Relay
Even Ford is a small cryptocurrency trading team focused on trading exchange listing announcements.
New exchange listings can cause significant and very rapid price movements. Our strategy depends on detecting these announcements as early as possible and reacting with very low latency.
On August 31, 2026, Upbit introduced a new Announcement WebSocket that delivers new and updated Upbit announcements in real time through its authenticated Private WebSocket API.
We are looking for an experienced low-latency software engineer based in Korea who has their own verified Upbit account and can build and operate a small relay service.
What you would do
You would:
- Create an Upbit API key with no trading, deposit, or withdrawal permissions.
- Keep the API credentials entirely within infrastructure controlled by you.
- Connect to Upbit's private WebSocket and subscribe to the
announcement stream. - Run a lightweight relay server on your own AWS instance or equivalent infrastructure.
- Forward newly received announcement events to our server with the lowest practical latency.
- Maintain the relay and connection reliability over time.
Because latency is important, the relay should be implemented using a high-performance compiled language, preferably C++ or Rust, with particular attention to network and processing latency.
Security
Your security is important, and the system is specifically designed so that you retain control of your Upbit account and credentials.
We will never ask you to:
- Send us your Upbit API Access Key or Secret Key.
- Give us access to your Upbit account.
- Enable trading, withdrawal, or deposit permissions.
- Give us SSH, AWS, or other infrastructure credentials.
- Run code supplied by us inside an environment containing your API credentials.
You implement and operate the relay yourself. We only receive the resulting Upbit announcement data.
Compensation
This is a paid, ongoing arrangement. Compensation is based on successfully receiving the announcement feed through your relay.
