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.

Key Responsibilities

- Make independent technical contributions to help their team deliver its commitments. 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. When possible, identify and leverage existing standard ones.
- 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.
- Collaborate with colleagues through code reviews, bug triaging, design documents, . .
- Contribute to shared team responsibilities (CI failure triaging, documentation, code fixits, rotations...).

Required Qualifications

- Bachelor or Master's degree in a relevant field.
- Experience in the relevant field (1-3yr).




- Solid knowledge about computer architecture (CPU, cache and memory hierarchy, buses, . . ).
- Knowledge about at least two of the following areas:
- Confidential computing technologies (RISC-V CoVE, Intel SGX, Intel TDX, AMD SEV, confidential containers).
- 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).
- Boot integrity technologies (UEFI Secure Boot, measured boot, TPM).
- 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

Preferred Qualifications

- Experience with assembly language (of any architecture).
- Experience with kernel and/or device driver development.
- Experience with hypervisor technology (KVM, Xen, Qemu).
- Experience with system boot technology (UEFI/EDK2, ACPI, u-boot, devicetree).
- Experience with open source software development. In particular, engagement with OpenSSF or other Open Source security organizations, and/or history of contributions to Open Source projects.




- Understanding of lifecycle management on firmware.
- Knowledge of JTAG debugging (including key generation and management).
- Experience working with hardware cryptography IPs.
