Principal Software Security Engineer

We need to output HTML fragment with sections: About the role? Actually we need to use headings for sections like About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. We must include only sections that have real specific content. We need to parse the posting. Key info: - Date posted, location, etc. Not needed as heading; we can put minor metadata in a short

or drop. - Position Role Type: Onsite. Not needed as heading; maybe include in a short p. - Requirements: Active and transferable U.S. government issued security clearance required prior to start date. U.S. citizenship required. Security clearance type: DoD Clearance: Secret. Security clearance status: Active and existing security clearance required on day 1. - About the company: paragraphs about RTX. - Role description: "We are currently seeking a Principal Software Security Engineer to join our Software Product Assurance team in McKinney, TX." - What You Will Do: bullet list of duties. - Qualifications You Must Have: list. - Qualifications We Prefer: list. - Benefits: mention benefits list. - Pay: salary range 107,500 USD - 204,500 USD. - Schedule: Not explicitly given; only Onsite role type. No schedule details. So we should not create Schedule section. - Also mention "Please consider the following role type definition as you apply for this role." Not needed. - Also mention application window etc. Not needed. We must not repeat job title as heading. So we will not have heading for Principal Software Security Engineer. We need to output only HTML fragment, no /, no markdown fences. We need to decide sections: - About the role? Could be the introductory paragraph about RTX and the role. Could be "About the role" heading containing description of role and company. - Responsibilities: the "What You Will Do" list. - Requirements: security clearance and citizenship. - Qualifications: could combine "Qualifications You Must Have" and "Qualifications We Prefer" maybe as two sub-sections? But we only have headings for Qualifications (maybe we can include both must and prefer under Qualifications). Could also have Skills heading for preferred? But we have Skills heading available. Could put must-have under Qualifications, preferred under Skills. However the instruction: "Use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)." So we can use those headings as appropriate. We need to preserve all substantive information. So we need to include both must-have and preferred qualifications. Could put must-have under Qualifications, preferred under Skills (since they are skills/experience). Or we could have two Qualifications sections? Not allowed duplicate headings? Probably okay to have one Qualifications heading and include both must and prefer as sublists with notes. But we need to preserve detail; we can include both. Better: Qualifications heading for must-have; Skills heading for preferred. Benefits heading for benefits list. Pay heading for salary range. We also need to include location and role type maybe in a short p after headings. We must not include boilerplate like EEO, privacy policy, etc. Let's extract content. Company description: Two paragraphs repeated: "At RTX, the world's largest aerospace and defense company, 185,000 great minds are united by purpose and inspired to make a difference solving the world’s most complex problems. With our three market leading businesses, world-class operations and investments in research and development, we offer capabilities and opportunity no one else can. Together, we push the boundaries of known science and find new ways to connect and protect our world. Raytheon brings the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today’s mission and stay ahead of tomorrow’s threat. We deliver solutions that help our nation and allies defend freedoms and deter aggression, creating a safer, more secure world. Join us and help shape the future of aerospace and defense." It appears twice; we should include only once. Then: "We are currently seeking a Principal Software Security Engineer to join our Software Product Assurance team in McKinney, TX." That's role intro. What You Will Do (Responsibilities): - Implement Software Security principles to embedded software design, development, integration, and testing of real-time sensor software. - Develop software applications using C and C++ languages on a variety of computing platforms - Ensure the SW Product Assurance processes are followed on our programs - Understand real-time software design and the performance implications associated with specific System Security implementations. - Work closely with cross functional Engineering teams to define and implement Test Driven Multidisciplinary Capability (TDMC) based execution development and deployment requirements. - Work in a common development environment to support and facilitate program ability to leverage specific capabilities. - Interface with customer community to review technical design and support verification of system maturity. Qualifications You Must Have: - Typically requires a Bachelor’s in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of 8 years of relevant software experience - Expertise with C / C++ - Experience with Static analysis concepts, methods & tools - Experience with Xilinx UltaScale+ MPSoC, Versal, or similar Embedded Processors - Experience with embedded OS like VxWorks, Embedded Linux, or similar - Experience using scripting languages like Python, Perl, or similar - Embedded Software Security experience - Active and transferable U.S. Government issued Secret clearance is required prior to start date. - U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance. Qualifications We Prefer: - Experience with Secure boot, containerization and software hardening - Experience with Cryptographic Algorithms - Experience in a technical leadership role to grow and lead a small technical team - Experience/knowledge of any of the following: - Designing, implementing, testing, or fielding real-time security-oriented solutions on Department of War (DoW) programs (embedded experience highly preferred) - Kernel or Device Driver development - Petalinux/Yocto operating systems - Agile/Scrum/Kanban frameworks and DevSecOps environments - Knowledge of modern computer architecture and hardware technologies including: - ARM Architecture - Interface protocols: PCIe, GPIO, I2C, SATA - Field Programmable Gate Arrays (FPGAs) - Application-Specific Integrated Circuits (ASICs) - Using software configuration management and bug tracking tools - Experience with validation and verification of software applications Benefits: list: medical, dental, vision, life insurance, short-term disability, long-term disability, 401(k) match, flexible spending accounts, flexible work schedules, employee assistance program, Employee Scholar Program, parental leave, paid time off, and holidays. Also mention annual short-term and/or long-term incentive compensation programs depending on level and collective bargaining; payments not guaranteed. Pay: salary range 107,500 USD - 204,500 USD. Schedule: Not given; we can omit. We also have role type Onsite; could include in a short p: "Role type: Onsite." We need to avoid repeating job title as heading. We'll output:
