Senior Mobile Software Engineer

Picarro, Inc • Santa Clara, CA

1d • $150,000 - $170,000

About The Position

Picarro is seeking a senior mobile engineer to own its field-facing mobile experience. The companion apps connect Picarro instruments with the cloud and data platform. The role calls for a product-engineering mindset: prototype quickly, ship reliable software, and take ownership in production while accounting for field conditions such as intermittent connectivity, outdoor and industrial use, and hardware pairing. The engineer will build for Android and iOS and collaborate with backend and platform engineers to support dependable mobile workflows.

Requirements

• At least 5 years of mobile engineering experience.
• Experience shipping production apps on Android and/or iOS using native Swift or Kotlin, or a cross-platform framework such as React Native or Flutter, with a clear rationale for the technology choice.
• Real-world experience with offline-first architecture and data synchronization patterns.
• Comfort 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; experience focused on internal IT, retail/e-commerce technology operations, or IT services and consulting primarily implementing or customizing other companies' software does not match the stated background.

Nice To Haves

• Experience integrating hardware or sensors through Bluetooth or similar protocols.
• A public GitHub or similar portfolio showcasing real project work.
• Experience building apps for field service, industrial, scientific, or instrumentation use cases.
• Familiarity with the cloud/data platform stack used by the backend team.
• 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 and data platform.
• Own offline-first architecture and data synchronization for field use, where connectivity is not guaranteed and data integrity is important.
• Implement device-level integrations, including Bluetooth/BLE, sensor pairing, and background data collection where relevant.
• Use AI-assisted development tools to prototype and iterate on user-interface and integration work.
• Own production reliability and performance, including crash rates, sync failures, battery and data usage, and root-cause fixes.
• Partner with backend and platform engineers to define APIs and contracts suited to field constraints.
• Mentor 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.
• 401(k).
• Social events, including a summer picnic, holiday party, and team lunches.
• On-site health and wellness programs, including fitness challenges, outdoor bootcamp, and flu shots.
• Bonus eligibility and equity as part of the total compensation package.
