At eyeo, we’re passionate about user agency, personal privacy, sustainability and keeping the web an open, fair resource for everyone.

How we work

eyeo has colleagues based all over the world. We practice agile and work in distributed, cross-functional teams that span nearly every timezone. Many of our tech teams prefer to work asynchronously.

What you’ll do

The Adblock Plus core and the Web Extension SDK built on top of it enable browser extensions to integrate ad-filtering capabilities, to improve user experience by blocking ads that don’t meet the Acceptable Ads criteria, and supporting online content creators via monetization.

As the Engineering lead for the ABP Web Extension SDK, your primary responsibility is ensuring that the engineers you support have what they need to be successful at eyeo and grow professionally. You are also responsible for the delivery of business value in your team, frequently but always in a sustainable way. Finally, you aim to constantly improve our partners’ experience, and to position eyeo as a trusted advisor that provides technical expertise supported by objective facts and metrics.

As a lead for strong engineers, technical leadership and a solid background in software development is a must. You'll have the opportunity to influence the culture, and work with your team on strategy and execution.

  • Contribute to the overall technical strategy of the unit and of eyeo, translate it into projects and deliverables, and help engineers understand how their daily work contributes to it.
