Position Overview

We are seeking a highly motivated Cryptography Research Engineer / Scientist to join our Advanced Security team located in Santa Clara, CA. This can be a hybrid position.

The Cryptography Research Scientist will be working on next-generation cryptographic technologies, with a primary focus on Fully Homomorphic Encryption (FHE) and additional involvement in Post-Quantum Cryptography (PQC). This position is intended for early-career researchers, typically candidates with a PhD and 0–2 years of relevant research or industry experience.

This role is centered on the research, optimization, implementation, and deployment of privacy-enhancing technologies for real-world applications. The ideal candidate will have strong mathematical foundations in modern cryptography, hands-on software development skills, and a passion for translating advanced cryptographic concepts into practical systems and Proof-of-Concept (PoC) demonstrations.

The candidate will work on cutting-edge problems involving encrypted computation, privacy-preserving AI/analytics, and quantum-safe cryptographic systems.

Key Responsibilities

• Conduct advanced research and development in Fully Homomorphic Encryption (FHE) and related privacy-enhancing technologies.
• Design, optimize, and implement FHE algorithms and pipelines for practical applications and deployment scenarios.
• Develop high-performance implementations for specialized use cases, including:privacy-preserving AI/ML inference,secure analytics and recommendation systems,confidential cloud computation.
• Develop and demonstrate Proof-of-Concept (PoC) systems showcasing practical FHE applications.
• Evaluate and integrate modern FHE frameworks and libraries such as:OpenFHE,HEAAN/CKKS-based frameworks,TFHE,Microsoft SEAL,PALISADE,Concrete,or related technologies.
• Contribute to research and development efforts in Post-Quantum Cryptography (PQC), including lattice-based cryptography and quantum-safe migration technologies.
• Collaborate with cross-functional engineering and product teams to transition research into deployable technologies.
• Track emerging developments in cryptography, privacy-enhancing technologies, and quantum-safe security.

Required Qualifications

• PhD in Computer Science, Mathematics, Electrical Engineering, Cryptography, or a related field, with 0-2 years of relevant industry experience.
• Strong theoretical background in modern cryptography, particularly lattice-based cryptography and/or Fully Homomorphic Encryption.
• Hands-on experience implementing cryptographic algorithms and optimizing performance-critical systems.
• Strong programming skills in languages such as:C++,Python,CUDA,Rust,or similar.
• Familiarity with one or more FHE libraries/frameworks.
• Strong understanding of algorithm optimization, computational complexity, and memory-performance tradeoffs.
• Ability to independently drive research ideas into working prototypes and PoCs.
• Strong analytical, problem-solving, and communication skills.

Preferred Qualifications

• Experience with GPU acceleration and high-performance computing for cryptographic workloads.
• Familiarity with CKKS, TFHE, BFV, or BGV schemes.
• Experience with encrypted machine learning or privacy-preserving AI systems.
• Knowledge of Post-Quantum Cryptography standards and NIST PQC algorithms (e.g., ML-KEM/Kyber, ML-DSA/Dilithium).
• Publications or open-source contributions in cryptography, security, or privacy-enhancing technologies.
• Experience working in research labs or advanced technology development environments.
