Job Opening: Mobile Developer for OONI Probe

Are you a mobile developer interested in defending human rights on the internet? We have a job opening for you!

The OONI team (a non-profit fighting internet censorship, originally born out of the Tor Project) is looking for a dedicated mobile developer to work on OONI Probe: a free software app designed to measure internet censorship and network performance.

The application deadline is Sunday, 31st October 2021.

Job description

If you join our team, you will lead the development of the OONI Probe mobile app, supporting human rights defenders worldwide to investigate and fight internet censorship.

You will work on improving the OONI Probe mobile app and create new features to meet our global community’s needs. The Android app is currently written in Java, while the iOS app is written in Objective-C, but you are also welcome to use Kotlin or Swift.

Ideally, you would work on both the Android and iOS versions of OONI Probe. But as OONI Probe Android is run by most OONI Probe users around the world, we are primarily interested in contracting a developer with strong Android app development experience and expertise.

This is a full-time 12-month contract position, starting ASAP. The contract may be extended depending on the contractor’s performance and the availability of funds. The yearly contractor fee will range between 50,000-60,000 EUR depending on the contractor’s relevant experience and expertise.

This is a fully remote position. Even before the COVID-19 pandemic, the OONI team always worked remotely online. We communicate and coordinate through OONI Slack channels, we have video/voice meetings regularly, and we track our work on GitHub.

Our team members are currently based in Europe and North America, but we encourage applications from anywhere in the world.

The Open Observatory of Network Interference (OONI) is a free software project – born out of the Tor Project in 2011 – that aims to empower decentralized efforts in increasing transparency of internet censorship around the world.

We build free software (OONI Probe) that enables anyone to independently detect internet censorship on their network. To increase transparency of internet censorship, we publish censorship measurements as open data in near real-time. This data supports research and advocacy efforts investigating and fighting internet censorship worldwide.

More information about OONI is available in our Mission Statement and FAQ.

OONI Probe

Launched in 2017, the OONI Probe mobile app is run by tens of thousands of users in around 200 countries and territories every month.

OONI Probe provides human rights defenders a user-friendly way to detect and collect evidence of internet censorship, and to contribute it as open data.

Thanks to OONI Probe users worldwide, millions of network measurements collected from 240 countries and territories have contributed towards the world’s largest open dataset on internet censorship.
