Job Description

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.

The base salary range for this full-time position is $150K to $170K. Our total compensation package includes base salary, bonus eligibility, and equity. Your base salary range and title will be determined based on the location, experience, qualification, skills, knowledge, level, and pay of employees in similar positions.

• 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

• Social events (summer picnic, holiday party, team lunches, etc.)
• On-site Health & Wellness programs (fitness challenges, outdoor bootcamp, flu-shots, etc.)
