Senior AI Compiler Engineer

About

Quarkslab is a French company specializing in information security R&D, consulting and software development. Our expertise is in combining offensive and defensive security to help organizations adopt a new security posture: Force the attackers, not the defender, to adapt constantly. Through our consulting services as well as our software we provide tailored solutions to organizations, helping them to protect their assets, sensitive data, and users against increasingly sophisticated attacks.

Quarkslab is an avid and active user of, and contributor to, Open Source Software and develops and maintains state-of-the-art security tools such as LIEF , QBDI, Triton,Irma, and several other projects.

We develop two commercial software products: Quarks Flow, a platform to automate and orchestrate security analysis of files at scale, and Quarks AppShield, advanced code and data protection software to disrupt code lifting, reverse engineering and tampering attacks.

What is Quarks AppShield?

At Quarkslab we develop Quarks AppShield, a software for application protection. Our solutions include a tool to protect Java/Kotlin programs and a C/C++ code-obfuscator based on LLVM, a white-box cryptography library, a RASP framework, a digital vault and remote attestation solutions. All these components help to increase the security of applications and firmware/middleware to protect IP, APIs, secrets and every sensitive information used or provided by software.

Your day to day work

The Quarks AppShield team is moving towards the protection of AI models deployed “at the edge” (e.g. mobile phones). We are building a solution that helps preventing the extraction of these AI models, even when the attacker controls the device running them. We’re focusing on a software-oriented approach, using methodologies inspired from data-flow aware obfuscating compilers.

The technological stack will be based on an already existing AI compiler (e.g. Glow/XLA).

If you like program analysis and compilation applied to security, machine learning technologies and building solutions from the ground up, you will love this job!

Who you are

The skills or knowledge we think you should have:

• Familiar with MLIR/LLVM, or other general-purpose compilation framework
• Knowledgeable in the usage of AI frameworks (e.g. Tensorflow, PyTorch), and associated compiler technologies (Glow/XLA)
• Development in C++
• Team player to exchange about your knowledge with others

But also, that would be nice if you knew:

• Reverse Engineering
• CMake, Git and Gitlab
• Python

Key Responsibilities:

• Your main task will be to design an architecture, build and develop this solution
• Write analyses to detect flaws in the design of the tool
• Ensure the quality of the delivered product in terms of security, performance and code size, and communicate your developments to the rest of the team.

Our recruitment process:

• Call with our talent acquisition manager.
• Video call with the Hiring Manager.

• Interview with C-Level, QAS business unit and HR Manager at Quarkslab’s Office (or remote due to Covid).
• HR debrief and job offer.

Why work at Quarkslab?

Work with an amazing team, eager to learn and play with new approaches and technologies, mixing various skills (security, compilation, program analysis, reverse engineering, software engineering). International environment with offices in Paris and Buenos Aires (team croissants vs. team asado), representations in Tokyo and Singapore.

• Attend conferences in your field, learn from many internal events (weekly conference, trainings, research activities).
• Contribute and support Open Source Software: Our own tools and other people’s projects.
• Flexible work hours, work from home.
