​Dear Ukrainians!

We here, at ADDENDUM, stand with you and condemn the brutal and unforgivable actions of the Kremlin.

We believe, that it's not enough what the modern Western world has already done for you.

You are showing bravery and defending not only your country, your life, and freedom, but the all-democratic world, you're defending the whole European Union!


This is why we're opening all our job opportunities and urging our worldwide partner network to do the same: help war refugees acclimatize as soon as possible!

Tech people: Developers, Testers, POs and PMs, Business Analysts, no matter the tech stack or experience, onsite or remote, temporary, part-time... Reach out to us, and we will do our best to speed up the process.

We will review our and our partner's open positions, share your details with companies in our contact network and help to point you in the right direction. We will do everything possible to help you find a job as soon as possible!

Слава Україні!
Разом до перемоги!
