Senior Mobile Software Engineer Android & iOS A senior mobile engineer who owns Picarro's mobile experience — field-facing companion apps that connect to physical instruments and the cloud/data platform. This role requires the same product-engineering-driven mindset as our other engineering roles: prototype fast, ship reliable software, and own it in production, with the added constraint of building for field conditions such as intermittent connectivity, outdoor/industrial use, and hardware pairing. Responsibilities Design and build native or cross-platform mobile applications for Android and iOS that pair with Picarro instruments and integrate with the cloud/data platform. Own offline-first and sync architecture for field use, where connectivity is not guaranteed and data integrity matters. Handle device-level integrations such as Bluetooth/BLE, sensor pairing, and background data collection where relevant. Use AI-assisted development tooling to prototype and iterate quickly on UI and integration work. Own mobile app reliability and performance in production, including crash rates, sync failures, battery/data usage, and root-cause fixes. Partner with backend/platform engineers to define APIs and contracts that work well under field constraints. Mentor other engineers on mobile architecture and platform-specific best practices. Qualifications 5+ years of mobile engineering experience, with production apps shipped on Android and/or iOS using native Swift/Kotlin or a cross-platform framework such as React Native or Flutter, with a clear rationale for the choice. Real experience with offline-first architecture and data sync patterns. Experience integrating with hardware/sensors via Bluetooth or similar protocols is a strong plus. Comfortable owning a mobile app's full lifecycle, including architecture, release process, monitoring, and production issues. Experience using AI coding assistants in a professional workflow.
