Senior Mobile Software Engineer

Picarro, Inc • Santa Clara, CA

8d • $150,000 - $170,000 • Onsite

About The Position

This role is for a Senior Mobile Software Engineer who will own Picarro's mobile experience, focusing on field-facing companion apps that connect to physical instruments and the cloud/data platform. The position requires a product-engineering-driven mindset, emphasizing rapid prototyping, reliable software delivery, and production ownership. Key challenges include building for field conditions such as intermittent connectivity, outdoor/industrial use, and hardware pairing.

Requirements

• 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 Haves

• 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.

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.

Benefits

• Medical, Dental, and Vision insurance
• Flexible Spending Account (FSA) and Health Savings Account (HSA) plans
• Life, Short-Term Disability, and Long-Term Disability Insurance
• Paid Time Off and Paid Holidays
• Employee Referral Program
• 401K
• Social events (summer picnic, holiday party, team lunches, etc.)
• On-site Health & Wellness programs (fitness challenges, outdoor bootcamp, flu-shots, etc.)
