The team
The Donjon is the team in charge of the security of all the products built at Ledger.
As part of that role, we closely track the state of the art of the whole spectrum of attack techniques, and strive to push its boundaries.
We are looking for a Hardware Security Researcher intern to work in the lab on Integrated Circuits reverse engineering, from sample preparation (decapping and delayering) to imaging using a Scanning Electron Microscope.
The techniques and methodology you will help develop will enable novel attacks on security sensitive targets, and allow to form a precise, anchored understanding of how to best thwart them.
What you'll be doing:
Research cutting-edge offensive security techniques.
Develop reverse engineering techniques and tools for Integrated Circuits manufactured on modern process nodes.
Develop attacks for the chips you studied based on reverse engineered information.
Formalize and generalize the attacks you find, and propose systematic ways to mitigate them or altogether render them impossible.
If time permits, submit your findings for publication in academic journals or specialised conferences.
What we're looking for:
Experience with programming in Python or Rust.
Basic understanding of (or strong curiosity towards) semiconductor devices and Integrated Circuits stack up and layout.
Interest in working in a hands-on, experimental lab environment.
Ability to formalize your work and shape concepts at the relevant abstraction level.
Ability to develop and document methods, standards, and guidelines.
Ability to clearly articulate and communicate your ideas, in written and spoken English.
At Ledger, we are dedicated to continually investing in our employees which is why we offer more than just salaries; we provide comprehensive compensation packages that include a wide range of benefits.
Here are some of the benefits you can look forward to:
Social: Frequent social events, snacks and drinks
