• 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, leveraging existing standards when possible.

• 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 hardening frameworks.
• Collaborate through code reviews, bug triaging, design documents, etc.
• Contribute to shared team responsibilities such as CI failure triaging, documentation, code fixits, rotations.

Required qualifications:

• Bachelor's or Master's degree in a relevant field.
• Experience in the relevant field (1-3 years).
• Solid knowledge of 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).
  • Cryptography usage across networks (certificates, signatures, TLS/SSL, PKI remote attestation).
• Knowledge of boot integrity technologies (UEFI Secure Boot, measured boot, TPM).
• 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 source control (git), continuous integration, task management (Jira).

Preferred qualifications:

• Experience with assembly language.
• 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 and contributions to security organizations or projects.
• Understanding of lifecycle management on firmware.
• Knowledge of JTAG debugging.
• Experience working with hardware cryptography IPs.

Soft skills:

• Team player, communicative and collaborative, focused on team outcomes.
• Curious about learning new technologies/stacks.
• Capable of within- and cross-team technical collaboration.
• Proactive, can-do attitude, self-motivated, and able to resolve obstacles.
