Azure Golang PHP React.js Ruby on Rails

BuySellAds ( | Fully REMOTE (US timezones strongly preferred)

We’re looking for an integration engineer with ad tech experience who wants to make ad tech a little less crappy

About us: BuySellAds operates the largest self-serve advertising marketplace on the web. We're an adtech company empowering publishers and advertisers to connect more efficiently. Don’t let the "adtech" part scare you away: our mission is to help publishers better monetize their sites so they can spend their time focusing on what they care about (their content!) rather than selling ads. We leverage tech to help broker these sales, and attempt to distance ourselves from the shady world of advertising that existed before.

Dribbble,, NPR, and The Atlantic are just some of the sites who we’re able to help make more money - connecting them with advertisers like Adobe, Microsoft Azure, Slack, Digital Ocean, and Atlassian who are all able to expand their reach through us.

We are a fully distributed/remote team, with 49 people spread out across 25 cities in 5 countries. We primarily use Rails and React, with a smattering of Go and PHP, but seek to hire developers who are language agnostic and are more interested in shipping quality code than bikeshedding it.

Interested? Send an email to Email is hidden (or ping me directly, firstname@) with some details on your background and what interests you about working with us.
