Job Background

Serving as the technical lead for the compliance portal, you will own and drive one of the company’s most challenging compliance-portal initiatives. The work involves multi-tenant architecture implementation and in-depth CI/CD customization. Beyond high technical complexity, this role demands strong cross-department orchestration capabilities.

Key Responsibilities

• Own multi-site core architecture. Lead end-to-end technical architecture design, technology selection and core development for the 'one-codebase, multi-site release' initiative. Resolve tough challenges including differentiated configuration across platforms/environments/tenants, dynamic UI-theming, and proper code isolation.
• Cross-functional technical alignment. Act as the central technical point-of-contact for this project, aligning Product, UI/UX, Backend Architecture, QA and DevOps teams. Define cross-platform interaction protocols, orchestrate resources, unblock technical bottlenecks across teams, and ensure high-quality on-time delivery.
• Build enterprise-grade DevOps & CI/CD. Design and implement fully-automated mobile build, test and release pipelines (e.g. Flavor / Target-based multi-target build solutions) to support frequent multi-site rollouts and significantly boost delivery efficiency.
• Technical deep-dive & performance optimization. Work deep within the Flutter Engine layer to resolve performance pain-points such as memory leaks and rendering jank under complex business scenarios. Establish and roll out mobile high-availability monitoring systems (Crash analytics, APM monitoring, etc.).

Requirements

• Strong ownership mindset. Take full accountability for business outcomes and engineering quality of the project. Proactively identify risks along the delivery chain and drive issues to closure with a strong bias for action.
• Excellent cross-functional collaboration. Possess solid communication, negotiation and conflict-resolution skills. Translate sophisticated technical concepts into business-friendly language, and drive consensus & tangible results amid conflicting priorities from multiple stakeholders.
• Demonstrated technical leadership. Influence and drive other teams through technical credibility - examples include pushing backend teams to refactor APIs or encouraging DevOps to upgrade pipelines. Comfortable making high-stakes technical decisions and taking corresponding risks.
• Education & baseline experience. Bachelor's degree or above in Computer Science or related fields. 5+ years of mobile (iOS / Android) engineering experience, with at least 3 years hands-on experience architecting and delivering complex production-grade Flutter projects.
• Multi-site / white-label architecture experience. Proven track record building large-scale variant apps, multi-tenant applications, unified multi-region releases, or heavily modularized systems. Deep expertise in Build Flavors / Targets, dynamic asset delivery and differential compilation.
• In-depth Flutter expertise. Solid understanding of Flutter rendering pipeline, Widget tree mechanics and Dart internals. Proficient in Flutter-Native hybrid development and communication patterns including MethodChannel.
• Engineering capability. Hands-on experience building sophisticated multi-flavor / multi-target CI/CD pipelines using Fastlane, Jenkins, GitHub Actions or equivalent tooling.

Nice-to-Have

• Led or played a core role in architecture evolution for mobile applications with millions of daily active users.
• Deep low-level development and performance-tuning experience in native platforms (iOS / Swift or Android / Kotlin).
• High-quality open-source Flutter contributions on GitHub, including PRs submitted to the official Flutter repository.
• Experience collaborating across multinational & cross-time-zone teams, or strong written & verbal English proficiency.
