Software Engineer

**Looking for experience in: ASSEMBLY, C, FIRMWARE, TPM, X86, EMBEDDED SOFTWARE,**AES, RSA, ECC, SHA, TLS, TLS/SSL, IPSec, SSH, PKI, e.g., FIPS 140-2, Common Criteria, ISO/IEC 27001

The EndoSec Cryptographic Software Engineer is responsible for designing, developing, and implementing cryptographic algorithms and protocols used in our products. The candidate will collaborate with other engineers and security experts to build secure and efficient systems, contributing to our products and services' ongoing security and privacy. This position requires the ability to apply for and maintain a U.S. Government Security Clearance. This is a remote position.

Key Responsibilities

Cryptographic Development: Design, implement, and optimize cryptographic algorithms and protocols, such as encryption, decryption, digital signatures, hashing, key exchange, and secure multi-party computation.

**Security Research:**Stay up-to-date with the latest developments in cryptography and cybersecurity and apply relevant research to improve product security and privacy.

Software Integration: Work with hardware engineers to integrate cryptographic solutions into software products, ensuring compliance with security best practices.

**Code Review and Testing:**Perform code reviews and contribute to security testing to identify vulnerabilities and ensure robust security measures.

**Performance Optimization:**Focus on optimizing cryptographic code for performance and security, balancing trade-offs where necessary.

**Documentation and Standards:**Create technical documentation for cryptographic implementations and adhere to industry standards (e.g., NIST, FIPS) and protocols.

**Collaboration:**Collaborate with other teams (e.g., backend, infrastructure, security, and product management) to ensure the cryptographic components meet the overall system requirements and security goals.

**Security Audits:**Participate in security audits and code reviews to identify weaknesses, recommend improvements, and ensure secure coding practices are followed.
