Cryptography & Platform Security Software Engineer

What you'll do

• Design and deliver cryptographic services and libraries for secure encryption, digital signatures, and key management.
• Build systems using public key cryptography like RSA, ECC, and DSA to support secure transactions and identity.
• Develop and improve PKI infrastructure including certificate lifecycle management and trust frameworks.
• Integrate cryptographic capabilities into Java-based services using JCA/JCE and hardware-backed security modules.
• Lead threat modeling, security reviews, and cryptographic design validation to mitigate risks.
• Optimize the performance, scalability, and resilience of cryptographic operations in high-throughput environments.

What we're looking for

• Bachelor’s degree, Master’s degree, or equivalent experience in Computer Science, Engineering, or a related field.
• Typically 7+ years of software engineering experience with a focus on security and cryptography.
• Proven hands-on experience with cryptographic algorithms and protocols including RSA, ECC, DSA, and digital signatures in production systems.
• Strong understanding of public key infrastructure (PKI), certificate management, and trust models in large-scale distributed environments.
• Proficiency in Java, including experience using JCA/JCE or building secure J2EE-based applications.
• Experience implementing or integrating with key management standards such as PKCS#11, KMIP, or similar protocols.
• Familiarity with secure coding practices and common cryptographic pitfalls.
