Job Description
Silicon Labs is seeking a Security Architect to lead the embedded secure element architecture for their multi-core wireless IoT SoC platform. The role involves ensuring silicon security by design, regulatory readiness, and optimization for low power and high performance. Responsibilities include architecting secure subsystems, drafting technical specifications, evaluating make-vs-buy decisions, ensuring regulatory alignment with frameworks like NIST and CRA/PSA/SESIP, optimizing for code-size, timing, and power, enabling cryptographic agility, advocating lifecycle security with customer features, and championing advanced security measures like side-channel countermeasures and AI-based anomaly detection.
Good To Have:
- 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.
Must Have:
- 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.
- Excellent English communication.
- Strong collaborator.
- Passionate problem-solver.
Perks:
- Meal vouchers for lunch
- Employee Referral Program
- Employee Wellness Program
- Paid days for philanthropy/volunteering
- Partial home working possibility

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.
Qualifications
Required:
- 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

- 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
