**Introduction** We are Firmware professional working on Z systems ( IBM Advanced Mainframes ) and we build the most secure systems for our customers to deploy their enterprise applications. IBM z Systems are deployed with workloads where intensive IO Operations are getting executed. IBM Lab works on IO enablement firmware as well as boot firmware for z Servers. Work area would be Initial program load that is Boot firmware which enables the z Systems to boot and load supported Operating systems( Linux, zOS, zVM ) on Logical partitions. **Your role and responsibilities** Crypto Express Adapter on z Systems allows companies to protect data and workloads from physical and logical attacks through cryptography. Cryptography is crucial for secure processing when applications must communicate with distributed elements or assess the validity of the data being processed. Candidate will be part of world class high-performance hardware security module (HSM) firmware team. The responsibility of the firmware team is to provide top-level security for processing and high-speed cryptographic offload **Required technical and professional expertise** Overall, 7+ years of IT experience Strong C++ programming is required to understand and implement HiMO modules and enhance the test suites. Develop HiMo modules (HW mimic) for Crypto cards response Develop HiMo modules (HW mimic) for TKE Should be bale to work with with senior technical members globally and the hardware team to make appropriate design decisions Experience in Functional Verification Test case development. Understanding test frameworks and hands-on experience with Robot automation framework would be an added advantage **Preferred technical and professional experience** Python programming and cryptography domain expertise
