Principal Software Engineer

As the Principal Software Engineer within the Product Engineering & Technology (PET) division, you serve as the

ultimate technical authority for our software development lifecycle.

You will aggressively champion the integration

of sovereign cryptography and post-quantum cryptographic (PQC) principles into our core CyProducts ecosystem,

ensuring unassailable compliance with NCA Essential Cybersecurity Controls (ECC).

This role demands a master level engineer capable of designing robust, high-assurance software that operates

flawlessly across advanced enterprise environments and highly sensitive, air-gapped sovereign infrastructures, and

of dictating the architectural runway for the entire division.

o Architect, engineer, and deploy highly resilient backend microservices using FastAPI, establishing

the definitive technical standard for backend development within the division.

o Embed advanced sovereign cryptography and post-quantum cryptographic concepts directly into the

application layer, ensuring all data in transit and at rest meets the highest national security

standards.

o Command the development of complex, reactive frontend architectures utilising Vue.js, ensuring a

seamless and highly performant user experience across the entire CyProducts ecosystem.

o Orchestrate the intricate integration of these frontends with high-assurance hardware appliances

deployed in sensitive industrial (OT) environments, guaranteeing flawless real-time synchronisation

and uncompromised data integrity.

o Provide battle-hardened technical leadership to the Dhahran-based engineering team, acting as the

definitive escalation point for complex codebase challenges.

o Enforce strict Secure Software Development Life Cycle (SSDLC) protocols from day zero, driving

zero-defect tolerance and embedding robust CI/CD pipelines in GitLab that automatically validate

code against uncompromising security thresholds before any deployment is authorised.

","requirements":" Bachelor's or master's degree (preferred) in Computer Science, Software Engineering, or a related highly technical discipline.

10+ years of hands-on software engineering experience, with a significant tenure operating explicitly at a principal or Lead Architect level.

You are a deeply technical, hands-on practitioner who writes elite-level code and architects

unassailable systems; this is emphatically not a role for administrative managers or those

who have stepped away from the command line.

You possess an exceptional track record of

designing, building, and operating complex distributed applications for high-stakes

environments.
