The SOAX.COM team is looking for an engineer to join the Tech team, specializing in software product development in GoLang.

SOAX is one of the largest proxy providers for business worldwide, a Global IP Proxy Network (IPPN). Our main product is Rotating Backconnect Proxies. We have an exclusive pool of over 8M IP addresses worldwide. All IP addresses in our pool belong to real ISPs (Internet Service Providers), so they have the highest level of trust from web services. Our clients mainly use residential and mobile proxies for parsing and scraping data on the web.

The company aims to build a fast, stable, and high-quality proxy service for client requests to external resources.

We are building a geo-distributed system written in GoLang, using interaction protocols such as HTTP/HTTPS/SOCKS5/TCP/UDP.

GitLab for code change history storage
Redash for product metrics monitoring
Maxmind GeoIp for device identification
Slack + Zoom for team communication
Notion for product documentation management

5+ years of work experience

Knowledge of Go and understanding of how runtime works (goroutines, channels)
Knowledge of sync, atomic, io, net, flag libraries
