LG Electronics North America is a global leader in technology dedicated to creating innovative solutions for a better life. They are seeking a highly motivated Cryptography Research Scientist to join their Advanced Security team, focusing on next-generation cryptographic technologies, particularly Fully Homomorphic Encryption (FHE) and Post-Quantum Cryptography (PQC). The role involves conducting research, optimizing implementations, and deploying privacy-enhancing technologies for real-world applications.

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

Skills

• 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
• 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
