Cryptography Research Scientist, FHE & PQC
About The Position
LG's Emerging Technology Lab (ETL) is seeking a highly motivated Cryptography Research Engineer / Scientist to join our Advanced Security team. This role focuses on next-generation cryptographic technologies, primarily Fully Homomorphic Encryption (FHE) and Post-Quantum Cryptography (PQC). It is designed for early-career researchers, typically with a PhD and 0-2 years of experience. The position involves research, optimization, implementation, and deployment of privacy-enhancing technologies for real-world applications. The ideal candidate will possess strong mathematical foundations in modern cryptography, practical software development skills, and a passion for translating advanced cryptographic concepts into functional systems and Proof-of-Concept (PoC) demonstrations. The role will tackle cutting-edge problems in encrypted computation, privacy-preserving AI/analytics, and quantum-safe cryptographic systems.
Requirements
- 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.
Nice To Haves
- 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.
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, and 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.
Benefits
- No-cost employee premiums for you and your eligible dependents for competitive medical, dental, vision and prescription benefits.
- Auto enrollment with immediate vesting of competitive company matching contributions in a 401(k) Retirement Savings Plan with several investment options.
- Generous Paid Time Off program that includes company holidays and a combined bank of paid sick and vacation time.
- Performance based Short-Term Incentives (varies by role).
- Access to confidential mental health resources to help you and your loved ones improve your quality of life.
- Personal fitness goal incentives.
- Family orientated benefits such as paid parental leave and support for families raising children with learning, social, behavioral challenges, or developmental disabilities.
- Group Rate Life and Disability Insurance.
