Senior Mobile Software Engineer

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.
• Background building software as a core product at a software product company, R&D lab, or technology-first organization, rather than internal IT, retail/e-commerce technology operations, or IT services/consulting shops that primarily implement or customize other companies' software.

Nice to Have

• A public GitHub or similar portfolio showcasing real project work is a strong plus.
• Experience building apps for field service, industrial, scientific, or instrumentation use cases.
• Familiarity with the same cloud/data platform stack used by the backend team, enabling smoother API collaboration.
• Cross-platform architecture experience, including shared business logic across Android and iOS.
