SDUI Lead Architect

Role Overview:

We are seeking a highly skilled SDUI (Server-Driven UI) Architect / Lead to drive the transition of our Quick Service Restaurant (QSR) mobile ordering app from an existing vendor to Capgemini team. This role requires expertise in reverse engineering the existing solution, establishing a robust SDUI-driven architecture, and ensuring seamless integration with backend systems, menu management, and ordering workflows. The ideal candidate will play a key role in enhancing app agility, scalability, and maintainability while ensuring a smooth transition with minimal business disruption.

Key Responsibilities:

• Reverse Engineering & Vendor Transition
• Analyze and reverse engineer the existing vendor-provided SDUI solution to extract system architecture, UI rendering logic, and dependencies.
• Document current implementations, including API contracts, caching mechanisms, feature flags, and DSL structures.
• Lead knowledge transfer sessions and onboard internal teams with a structured transition roadmap.
• Establish ownership of SDUI components, ensuring a smooth migration to existing development teams.
• SDUI Architecture & Implementation
• Design and implement a scalable SDUI framework tailored for a high-volume QSR mobile appwith millions of active users.
• Optimize menu configurations, promotions, loyalty programs, and ordering flows using SDUI-driven dynamic UI updates.
• Work closely with backend teams to define DSL structures, API contracts, and caching strategiesfor efficient UI rendering.
• Implement market-based configurations, feature flagging, and A/B testing to enable rapid iteration and personalization.
• Performance, Scalability & NFR Compliance

Ensure solutions meet QSR-specific Non-Functional Requirements (NFRs), such as:

• Low-latency ordering for peak hours (e.g., lunch rush).
• High availability & real-time updates for menu changes.
• Offline caching strategies for seamless user experience.

Optimize API response times, network efficiency, and UI rendering performance to enhance user experience.

• Cross-Team Collaboration & Technical Leadership
• Partner with Product, UX, and Engineering teams to align SDUI-driven feature rollouts and roadmap execution.
• collaborate with backend services, CMS, and third-party integrations (e.g., loyalty platforms, POS systems, delivery aggregators).
• Provide technical guidance, mentorship, and enforce best practices for SDUI adoption and scalable mobile architecture.
• Post-Transition Support & Continuous Innovation
• Establish monitoring, observability, and CI/CD automation for SDUI updates without requiring app store releases.
• Conduct post-transition audits to identify gaps, optimizations, and future enhancements.
• Explore AI-driven UI personalization, real-time pricing strategies, and ML-based menu recommendations for enhanced user engagement.

Ideal Candidate Profile:

• Expertise in SDUI-driven mobile architectures for high-traffic QSR or consumer-facing apps.
• Strong knowledge of reverse engineering mobile app architectures, API structures, and rendering engines.
• deep experience in iOS (SwiftUI), Android (Jetpack Compose), and backend SDUI rendering engines.
• Proven track record in vendor transitions, large-scale app migrations, and technical due diligence.
• Understanding of QSR-specific technologies (e.g., order orchestration, menu management, loyalty, and payments).
• Strong skills in performance tuning, caching strategies, API optimizations, and observability tools.
• If you have any queried, do let us know.
