Product Security Engineer, Cryptography & PKI

About 1X

We’re an AI and robotics company based in Palo Alto, California, on a mission to build a truly abundant society through general‑purpose robots capable of performing any kind of work autonomously. We believe that to truly understand the world and grow in intelligence, humanoid robots must live and learn alongside us. That’s why we’re focused on developing friendly home robots designed to integrate seamlessly into everyday life. We’re looking for curious, driven, and passionate people who want to help shape the future of robotics and AI. If this mission excites you, we’d be thrilled to hear from you and explore how you might contribute to our journey.

Role Overview

As a Product Security Engineer specializing in cryptography and PKI, you will be responsible for designing, implementing, and scaling cryptographic infrastructure that underpins the security of our firmware, devices, and communications. You will drive work from root‑of‑trust with hardware security modules (HSMs), build secure pipelines for firmware and certificate management, and collaborate across teams to embed best practices in secure device provisioning, attestation, and lifecycle management. Your impact will help ensure the integrity and trustworthiness of our robot fleet at scale.

Responsibilities

• Design and manage end‑to‑end cryptographic services, including public key infrastructure (PKI) and key lifecycle manag
• ementEstablish HSM infrastructure as the root‑of‑trust for firmware signing and IoT endpoint authentic
• ationLead evaluation, procurement, installation, configuration, and integration of HSM vendor solu
• tionsArchitect key management systems that scale from hundreds of devices today to millions over
• timeDesign remote device attestation mechanisms (e.g. fTPM, OP‑TEE, or equivalent) tied to the HSM root‑of‑

• ctionSecure build/artifact pipelines and code‑signing work
• flowsDevelop factory provisioning architecture for mass key/certificate distrib
• utionSupport the development of secure communication prot
• ocolsCollaborate closely with Product Security, Cloud Infrastructure, Device Engineering, and SecOps teams as an individual contributor.

Job Requirements

• Strong experience with cryptography, PKI design, and key management
• Experience working with hardware security modules (HSMs), including vendor selection, integration, and root‑of‑trust establishment.
• Familiarity with remote device attestation frameworks (such as fTPM, OP‑TEE, or similar)
• Demonstrated ability to design and scale secure firmware signing and code signing pipelines
• Proven track record in defining and enforcing trust policies (key generation, rotation, destruction) and provisioning mechanisms
• Experience securing build/artifact pipelines and developing secure communication protocols
• Ability to work cross‑functionally with hardware, software, security operations, and infrastructureteams
• High attention to detail, strong problem solving, with a mindset of anticipating vulnerabilities and designing defendable systems

Nice to Have:

• Vendor-specific HSM credentials or labs (Thales, Utimaco, AWS CloudHSM)
• NVIDIA Orin or similar SoC platform experience
• Background in post-quantum crypto evaluation and migration planning
• Familiarity with large-scale factory provisioning tools (KMIP gateways, ACME/SCEP)
• ProdSec/supply-chain security expertise (SBOMs, CI/CD hardening)
• Experience in C/C++/Rust/GoLang (in addition to Python/ Bash)
• GoLang preferred
• Additional security certifications
