Openchip is building new RISC-V chips with security at heart, enabling safer and more privacy-respectful execution of data processing workloads like AI models.
As a Junior Security Software Engineer, you will design and implement security features across Openchip's software stack: from low-level platform firmware to integrations with AI and Cloud runtimes. You will also contribute to hardware/software co-design, providing requirements and identifying potential IPs, as well as engage with the wider security community.
In particular:
Develop and maintain security features for novel and existing hardware architectures (RISC-V and others).
Implement secure boot, confidential computing, cryptography, and other platform security features.
Define new interfaces and modify existing ones to expose security features to user applications. Interact with colleagues across projects to unblock issues, or to reach consensus on technical topics. In particular:
Work with firmware and operating systems teams, incorporating security features into low-level and platform software.
Work with middleware teams,



exposing security features to user applications and/or hardening frameworks.
Bachelor or Master’s degree in a relevant field.
Platform security features (kernel/firmware hardening, CHERI, CFI, pointer tagging, virtualization-based security, IOMMU).
Cryptograpy usage across networks (certificates, signatures, TLS/SSL, PKI remote attestation).
Cryptography, including experience with cryptography libraries (OpenSSL, libssl, wolfssl, mbedtls, libsodium).

Good understanding of pre-boot and boot process, and Linux kernel internals.
Solid knowledge of low-level development languages (C, Rust).
Experience with standard tools for source control (git), continuous integration, task management (Jira).
English level minimum B2
Experience with assembly language (of any architecture).
Experience with open source software development. In particular, engagement with OpenSSF or other Open Source secu
