Job description

Principal Software Engineer - Mobile SDK Tooling & On-Device Computer Vision (iOS/Android)

Established in 1927, SICPA is a Swiss private technology company that supports the effective governance and long-term prosperity of nations.

SICPA sets the pulse of sovereignty, enabling governments to protect their citizens, sovereign assets, and economies. Best known for securing the majority of the world’s banknotes, SICPA operates across five continents.Today, our platform for sovereignty delivers integrated solutions safeguarding revenue mobilisation, natural resources, health, and brand protection as well as digital sovereignty and secure public services.

ROLE

• Strengthen observability and diagnostics for SDKs and reference apps using Splunk and other tools (logs, metrics, crash signals, field diagnostics).
• Build and own engineering tooling and automation, and define a multi-quarter platform roadmap, to measurably reduce operational workload and increase developer productivity at scale across the team (~20 engineers), while reducing integration and support effort.
• Design, implement, and maintain Continuous Integration / Continuous Delivery pipelines and quality gates (Jenkins) for mobile SDKs (build, test, packaging, release validation, regression detection).
• Develop release qualification frameworks: automated functional tests, performance benchmarks, compatibility checks, and reproducible test environments.
• Deliver and evolve core components of mobile SDKs (iOS, Android): camera capture, image processing pipelines, API design, modularization, documentation, smartphone apps.
• Provide technical leadership as an Individual Contributor (no management): architecture decisions, design reviews, mentoring through code reviews, and raising engineering standards.
• Lead the integration of AI/ML into the mobile detection stack, from rapid prototyping to production-grade deployment on iOS/Android.
• Build an AI-driven validation and triage layer for SDK releases, including automated regression and anomaly detection.

PROFILE

• Principal Engineer with a strong track record of delivering production software.
• Proven experience building developer tooling / automation platforms that measurably improve team productivity (e.g., faster releases, fewer regressions, reduced support load).
• Strong iOS expertise: Swift, Xcode, SDK design and packaging, performance profiling (Instruments); Objective C is a plus.
• Solid Android foundations: Kotlin/Java, Gradle, CameraX/Camera2, instrumentation/testing; ability to support and debug across both platforms.
• Strong understanding of CI/CD concepts and implementation experience with Jenkins (pipelines, build/test orchestration, quality gates, artifacts, release processes).
• Strong knowledge of software architecture, API design, testing strategy, secure coding practices, and maintaining high-quality codebases.
• Hands-on experience building and optimizing computer vision / image processing pipelines on mobile devices and under real-world constraints (latency, memory, device variability).
• Strong problem-solving skills, translating customer needs into scalable solutions.
• Hands-on experience deploying AI/ML models to production on resource-constrained, heterogeneous devices.
• Solid expertise in the full ML lifecycle, including data quality, evaluation, robustness, and model release management.
• Practical experience with on-device ML toolchains and runtimes and performance engineering under real device constraints.
• Ability to define and enforce AI usage standards in an industrial environment.
• Strong communication and collaboration skills in multicultural environments; fluent English, French is a strong plus.
