Job description

Join one of the world’s largest industrial security teams — and build technology that protects real devices worldwide. At NXP’s Competence Center Crypto & Security, we design, build, and deliver end-to-end security — from early innovation to architecture to products in the field. If you're a security engineer who wants to create real-world impact, we’d love to hear from you. Ready to join the future of innovation in Crypto & Security at NXP? Become part of a highly talented and dynamic international team that develops and tests state‑of‑the‑art secure cryptographic libraries protected against physical and logical attacks which have applications across all different NXP domains and business lines (payment, identification, mobile, IoT, Automotive, Edge Processing, etc.).

The main challenge for an Embedded Senior Crypto Software Developer in this role is to find the required trade off to meet the challenging demands with respect to performance/memory footprint and particularly security for the entire NXP Security portfolio. Moreover, the Crypto Libraries have to meet various Certification Requirements up to the highest level (e.g. Common Criteria up to EAL 6+). In order to achieve this, this role requires a deep knowledge of various embedded architectures (in particular ARM/RiscV).

Responsibilities

• Specification and cross‑platform implementation of state‑of‑the‑art cryptographic algorithms (incl. Post‑Quantum Cryptography) and secure software based on functional requirements.
• Design and specification of software countermeasures against physical attacks such as Side‑Channel Analysis (SCA) and Fault Injection (FI).
• Implementation of designed software countermeasures.
• Collaboration with security architects and internal evaluation teams to enhance software countermeasures.
• Taking ownership of technical topics within cryptographic domains through design, implementation, code reviews, architectural contributions and technical planning.
• Collaboration with OS and firmware teams to ensure clean and secure integration of the cryptographic software into the final product.
• Working closely with the group’s test and platform support engineers to ensure maximum product quality.
• Supporting product certification activities and security evaluations.

Your Profile

• BSc, MSc or PhD in mathematics, cryptography, computer science, electronic/ electrical engineering, information technology or relevant discipline.
• 5+ years of relevant industry experience in cryptography and embedded security (or an equivalent combination of advanced degree and relevant experience), with strong understanding and implementation of cryptographic primitives (e.g., ECC, RSA, AES, SHA‑2/SHA‑3).
• Solid experience in embedded software development using C and Assembly, and good knowledge of microcontroller architecture (e.g., ARM Cortex‑M, RISC‑V).
• Knowledge of hardware and software countermeasures against side‑channel and fault‑injection attacks.
• Experience in Post‑Quantum Cryptography is a plus.
• Experience with Rust is a plus.
• Strong debugging and analysis skills.
• You are a proactive team player with a strong sense of ownership and a proven ability to deliver results.

We offer

• Work on state‑of‑the‑art cryptographic software, including traditional and post‑quantum cryptography, on ARM Cortex‑M and RISC‑V platforms.
• Develop innovative countermeasures against Side‑Channel Analysis (SCA) and Fault Injection (FI) attacks.
• Take ownership of key technical topics within cryptographic domains and work closely with cross‑functional teams.
• Collaborate with leading security experts across architecture, evaluation, firmware and certification domains.
• Contribute to solutions that safeguard applications across automotive, payment, identification, mobile, industrial, and IoT markets.

Benefits and Compensation

• For applications in Gratkorn: NXP provides market competitive compensation according to the benchmarking of the electronic and semiconductor industry.
• Due to the Austrian Equal Treatment Act we are obligated to state the employment group of our applicable collective bargaining agreement (CBA) “Kollektivvertrag für Angestellte Gewerbe und Handwerk und in der Dienstleistung”, this position (fulltime) is graded in Employment Group V.
• Individual experiences and expectations will be considered in the application process.
• Attractive benefits including home office, flexible working time, meal benefits and more.
• Online and offline learning opportunities to help develop core and professional skills.

Please note: The successful candidate may/will be responsible for security related tasks. The assignment may/will be in scope of security certifications, therefore a conscious and reliable way of working is necessary.
