Your MissionJoin a high‑caliber embedded security software team alongside experienced architects and domain experts. You’ll lead the embedded secure element architecture in our multi‑core wireless IoT SoC platform. Your work ensures our silicon is secure‑by‑design, regulation‑ready, and optimized for ultra‑low power, high performance, and minimal footprint.

You’ll define technical specs, evaluate make‑vs‑buy decisions, and deliver practical, future‑proof solutions—ready not just for today’s threats but for the quantum era and beyond.Responsibilities

• Architect secure subsystems: secure boot, anti‑rollback, cryptographic services, firmware update, storage, key mgmt.
• Draft technical specifications: clearly define requirements and interfaces—for internal builds or third‑party components. Drive technical relations with our main IP provider.
• Make‑vs‑buy technical analysis: lead evaluations of IP and deep technical relation with vendor, crypto stacks, provisioning services, and third‑party tools.
• Regulatory alignment: embed NIST, CRA/PSA/SESIP frameworks into silicon architecture and follow certification.
• Optimize for constraints: own code‑size, timing, power KPIs; collaborate with systems/hardware/software teams.
• Enable cryptographic agility: include post‑quantum crypto, future‑proof update paths.
• Advocate lifecycle security with appropriate customer DX allowing high level features secure OTA, secure erase, live reporting, device decommissioning, ownership transfer….
• Stay ahead: champion side‑channel counter‑measures, tamper detection, and AI‑based anomaly detection for robust, future‑ready security.

QualificationsRequired:

• BS/MS in Electrical/Computer Engineering or related.
• 8+ years in embedded security, trusted execution, cryptographic firmware, or SoC security.
• Strong C/C++ skills, low-level embedded and secure coding practices.
• Familiarity with TrustZone‑M, RISC‑V PMP, secure enclaves, PUF, HSM, secure identity and attestation.
• Experience in SW SE and or crypto libraries for multi core SOC
• Experience drafting technical specs and vendor/IP evaluation.

Preferred:

• Wireless IoT protocols (Matter, BLE, Thread, Zigbee, Wi‑Fi).
• PQC, cryptographic engines, post‑quantum key exchange/signature.
• Side‑channel resistance, fault detection, tamper sensors.
• Hardware/software threat modeling, certification experience (PSA, FIPS, Common Criteria).
• Track record balancing security with strict code‑size, timing, and power budgets.

You Bring:

• Excellent English communication—able to articulate security architecture to customers, regulators, and partners.
• Strong collaborator—thrives in peer architect teams; able to influence and align across software, hardware, and systems.
• Passionate problem-solver—driven by measurable outcomes and real-world constraints.

Why Join Us?

• Impact: Architect foundational security IP that powers billions of connected devices.
• Growth: Work with teammates who live innovation—“find better ways,” “walk the talk,” “nurture greatness”.
• Future-ready: Help define the roadmap for secure enclaves, AI-based defenses, and quantum-resistant silicon beyond 2030.
• Culture: Built on flexibility, learning, integrity, and results
