Description
Mobile Developer (Android & iOS) | Cyber Security Technology | Estonia - Tartu or Tallin location
Your code will help secure the integrity of national elections.
This company builds an end-to-end verifiable online voting platform trusted by governments and institutions across the world.
They sit at the intersection of cryptography, election integrity and software engineering, and every release they ship meets the highest standards of security, auditability and regulatory compliance.
They are a small, technically focused team based in Estonia.
Here, your work is never lost in the noise: every feature you build has a direct and visible impact on how elections are run.
The role
You will develop and maintain native mobile applications across their election technology portfolio, spanning voter registration, voter verification devices and individual verifiability mechanisms.
