The Opportunity

You will be part of a highly flexible development teamfor the Me TSHardware Security Moduleswith members in Brussels, Aachen and abroad, so good communication skills are essential.

The Software Architectand Project Managerfor the Me TSHSM isresponsiblefor designing theembedded applicationsoftwareofthe Hardware Security Module (HSM).

This role requires expertise in embedded programming, a strong background in C and experience withapplied cryptography and cryptographic primitives.

This roleisas another aspect alsoresponsible for the close management and coordination of an offshore development team from our German office, ensuring the quality, consistency and timely delivery of the system software for the Hardware Security Module (HSM).

This requires hands-on technical involvement — including systematic source code reviews, creation and validation of cryptographic test vectors, and architectural guidance — combined with strong project management discipline.

Day-to-Day Responsibilities

Managing and steering an offshore development team to deliver security products in embedded systems for financial transactions, smart grid, e Health and others.

Overseeing the definition, analysis, development and validation of security-related applications on a Hardware Security Module, with direct technical involvement in code quality, testing and architecture.

Help developing the architecture of security products in embedded systems for financial transactions, smart grid, e Health and others.

Defining, analyzing, developing and validating security-related applications on a Hardware Security Module.

Key Responsibilities

• System Design: Develop and maintain the architecture for the system software of the Me TS HSMs ADYTON and ASM.
• Technical and Project Leadership: Guide and support in-house and offshore development teams in best practices for implementing the HSM software.
• Agile Development: Collaborate with cross-functional teams in anagile environment, participating in sprint planning, reviews, and retrospectives.
• Stakeholder Collaboration: Work closely with the Product Owner and Product Manager to gather requirements, prioritize features, and translate them into technical specifications.
• Documentation: Create andmaintaincomprehensive documentation of interface designs, and security measures specific to the Me TSHSMs.
• Quality Assurance: Ensure that software solutions adhere to industry standards for security and performance.
• Problem Solving: Identify and resolve technical challenges related to Me TS HSM integration.
• You are a technical leader able to lead and guide off-shore and in-house teams in architecture, analysis and developments for made-to-measure customer solutions.
• You have a strong background in C, it would be apricated if you have a good knowledge in C++ and Java.

The team work in an agile environment with a high demand of independent, autonomously and pro-active way to structure tasks and solve issues.

• The ideal candidate should possess proficiency in C programming and embedded systems development, along with a strong understanding of cryptography.
• Experience with secure coding practices and security standards is essential.
