• Provide hands-on technical leadership across design, implementation, integration, release, and production operations. 

• Lead and challenge vendor engineering teams, ensuring compliance with Qiddiya Digital standards. 

• Review and approve architecture, APIs, data models, integrations, code quality, and major technical decisions. 

• Validate vendor deliverables using clear acceptance criteria and measurable technical evidence. 

• Ensure solutions are resilient, reliable, scalable, secure, observable, maintainable, and cost efficient. 

• Define and monitor technical KPIs, service-level objectives, availability, latency, recovery, and performance targets. 

• Ensure appropriate automated testing, CI/CD controls, monitoring, logging, tracing, and alerting are in place. 

• Validate release plans, rollout strategies, rollback procedures, capacity testing, disaster recovery, and production readiness. 

• Lead technical incident management, root-cause analysis, and permanent remediation. 

• Identify and manage technical debt, architectural risks, recurring incidents, and operational weaknesses. 

• Maintain architecture documentation, technical decisions, runbooks, and support procedures. 

• Drive knowledge transfer and ensure Qiddiya can independently operate and evolve the platform. 

• Promote reusable capabilities and common engineering practices across Qiddiya’s digital assets. 

Requirements

• Bachelor's degree in Computer Science, Software Engineering, Information Technology, or a related discipline.
• Extensive software-engineering experience in a Lead, Staff, Principal Engineer, Technical Lead, or senior architecture role. 

• Strong hands-on engineering capability and the ability to challenge implementation-level decisions. 

• Experience designing and operating large-scale, distributed, cloud-native, and highly available platforms. 

• Experience with customer-facing digital products, commerce, payments, loyalty, identity, ticketing, mobile, or similar platforms. 

• Strong knowledge of APIs, microservices, event-driven architecture, distributed systems, data consistency, and failure recovery. 

• Strong experience with resilience, observability, performance engineering, security, automated testing, CI/CD, and production operations. 

• Experience defining technical KPIs, service-level objectives, non-functional requirements, and acceptance criteria. 

• Proven experience overseeing vendors, system integrators, or outsourced engineering teams. 

• Strong incident-management, root-cause-analysis, and problem-management experience. 

• Strong communication, stakeholder-management, and technical decision-making skills
