POSITION DESCRIPTION /

Niobium Microsystems is seeking a cryptographer with significant experience in secure computation techniques, with particular focus on modern fully homomorphic encryption (FHE) schemes and their underlying mathematics. 5 years of relevant industry experience preferred. Reporting to the Chief Technology Officer (CTO), the successful candidate will be responsible for optimizing Niobium’s FHE architecture and associated scheme optimizations to take maximum advantage of that architecture. Candidate will also be responsible for forward-looking additions to our FHE capabilities, including multi-key / multi-party FHE. Candidate will also shape our client-side application stack for automation in FHE parameter selection. The Niobium environment is fast-paced with overlapping priorities and requires the candidate to be highly flexible, able to juggle multiple tasks at once. This position is integral to the success and growth of Niobium Microsystems.

JOB RESPONSIBILITIES /

Overview of Primary Responsibilities:

• Extend beyond OpenFHE to optimize core algorithms (bootstrapping, key-switching, NTT) for high throughput and excellent locality of reference
• Extend capabilities to include multi-key / multi-party FHE
• Design concise network data transport client-to-server 
• Enhance on-chip acceleration such as key-switching key and NTT twiddle factor generation
• Mentor compiler and design team on FHE mathematics and optimizations

DESIRED SKILLS & EXPERIENCE /

Required:

• Deep expertise in modern fully homomorphic encryption (FHE) schemes and current research in FHE
• Demonstrated working knowledge of program optimization and memory hierarchy management
• Experience in application performance modeling using detailed processor execution models
• Experience in creating and characterizing performance using micro- and macro-benchmarks
• B.S. / M.S. in Computer Science or Cryptography
• Ability to multi-task and prioritize in a fast-paced environment; managing multiple complex, multidisciplinary tasks and projects
• Ability to work collaboratively across teams and communicate effectively
• Attention to detail and remarkable eye for accuracy
• Willingness to learn and develop new skills

Preferred:

• PhD focused on homomorphic encryption or lattice mathematics
• Experience in development of homomorphic encryption libraries and application development
