Research Software Engineer

Mission

The Center for Digital Trust (C4DT), housed at EPFL, brings together businesses, research community, civil society, and policy actors to collaborate, share insight, shape the research agenda, and to gain early access to trust-­building technologies.

C4DT develops the expertise, methods, and software to enhance privacy, data protection, and transparency; notably by the use of cryptography, blockchains and smart contracts, machine learning, software verification, device and system security. Its research scope covers, among others, finance technologies, health-data security and privacy, technologies for trustworthy governance, democracy, and humanitarian needs.

An important mission of C4DT is to promote innovation and to facilitate technology transfer, by fostering projects between EPFL’s laboratories and our partners. It is where research meets industry requirements.

You will be working on a research grant from Innosuisse on the topic of "Self-recovery of end-to-end encrypted vaults". This work entails helping develop cryptographic algorithms in collaboration with the C4DT team, a laboratory (Professor, PhD students, Research Software Engineers, semester students) writing software libraries and applications, and evaluating them through user tests. The duration of the grant is 2 years.
