PhD position at FU Berlin for embedded GNU Taler wallet

We are seeking a PhD student to create a Taler wallet that can run on an embedded system (not smartphone or browser).


    Key points:
  • checkmarkYour PhD advisor would be Prof. Matthias Wählisch, co-founder of RiotOS. Christian Grothoff (GNU Taler maintainer) is officially a co-advisor on the project.
  • checkmarkThe position is in Berlin, you will be expected to relocate there; the initial contract will be for 3 years, however, a typical PhD in Germany is expected to take 5 years (so plan for ~5 years). The earliest possible start date would be November 1, 2022.
  • checkmarkYour salary will be 100% TVL-13; the exact amount depends on years of experience and family status (and includes contributions to health insurance and retirement). See Summary for a "simple" calculation by experience.

    Requirements:
  • checkmarkYou will write Free Software only, collaborate with the GNU Taler core team and help the GNU project.
  • checkmarkThe working language of the group is English.
  • checkmarkYou need to have a Master's degree in computer science or a related field (mathematics, embedded systems). Our ideal candidate would have a background in embedded/microcontroller programming, and networking (TCP/IP).
  • checkmarkThe main project goal is to create a Taler wallet that can run on an "embedded" system (so not a smartphone or a browser) by eliminating the current wallet's dependency on NodeJS/JavaScript and allowing it to run on platforms like RiotOS. This should then (1) improve the security of the wallet (by reducing complexity), (2) allow citizens to use Taler without a smartphone (by buying some ideally much cheaper hardware), and (3) possibly set the stage to enable Taler to be used offline.
