Lead Engineer - Advanced Cryptography

Job Description 

We are seeking an Advanced Cryptography Specialist with strong expertise in topics like multiparty computation (MPC), post-quantum cryptography (PQC) and zero-knowledge proofs (ZKPs). The ideal candidate will hold a PhD or MS in cryptography or a closely related field and have several years of hands-on experience applying advanced cryptographic techniques within the financial sector. The candidate will help leverage innovative cryptography at JPMorgan Chase.  As a member of the Emerging Technologies Security group within the Cybersecurity & Technology Controls organization, you will work alongside cryptographers and a group of passionate security engineers to solve complex security problems and support the deployment of cryptography-based solutions. 

The position requires software development experience and strong industry experience (5 years or more) in combining cryptography and security best-practices to secure complex IT infrastructure, customer-facing services, and sensitive customer and enterprise data. 

Key Responsibilities: 

• Research & Development: Lead the analysis and use of cryptographic protocols, with a focus on multiparty computation, quantum-safe cryptography and zero-knowledge proofs. 
• Solution Implementation: Architect and implement cryptographic solutions for privacy and confidentiality in financial and non-financial applications, including blockchain-based systems. 
• Collaboration: Work closely with other cryptographers, product, engineering, and compliance teams to integrate advanced cryptographic techniques into real-world financial products and services. 
• Security Assessment: Evaluate and enhance the security of existing and new cryptographic protocols, ensuring compliance with industry standards and regulatory requirements. 
• Thought Leadership: Stay abreast of the latest research in cryptography and privacy, and represent the organization in academic and industry forums. 
• Mentorship: Guide and mentor junior cryptographers and engineers in advanced cryptographic concepts and best practices. 
• Assess existing cryptographic libraries 
• Evaluate existing crypto-agile approaches and tools – help define and implement JPMC-centric solutions 
• Assist with performance impact assessment of post-quantum cryptography solutions and deployments 
• Communicate ongoing work with other teams or organizations 

Required Qualifications: 

• Education: PhD or MS in Cryptography, Computer Science, Mathematics, or a closely related field, with a dissertation or significant research in multiparty computation, quantum-safe cryptography or zero-knowledge proofs. 
• Experience: Minimum 5 years of post-PhD/MS experience applying advanced cryptographic techniques, preferably in the financial sector (e.g., banking, payments, digital assets, or related domains). 
• Proficiency in cryptographic protocol design, analysis, and implementation. 
• Experience with cryptographic libraries and tools (e.g., MP-SPDZ, FRESCO, SEAL, HElib, libsnark, Zokrates, Circom, or similar). 
• Proficiency in cryptography applied to network security protocols (e.g., TLS, IPsec etc.) 
• Industry Knowledge: Familiarity with regulatory and compliance considerations for privacy technologies in the financial sector. 
• Communication: Excellent written and verbal communication skills, with the ability to explain complex concepts to technical and non-technical audiences.
