[Hiring] Lead Mobile Engineer @Hauler Hero Inc.

Role Description

We are hiring a Lead Mobile Engineer (Contractor) to be the most senior engineer on our mobile team. Today we have a native Kotlin Android app; you will help evaluate Kotlin Multiplatform and lead the build-out of our first iOS app (iPad first, phones later) while strengthening the offline-first foundation across both platforms. This is a hands-on role. You will write code daily, drive architectural decisions across iOS and Android, and mentor the mobile team. It requires strong technical judgment, comfort with ambiguity, and clear communication in a remote environment.

We are intentionally building an AI-assisted engineering organization. AI tools are part of the daily workflow, not optional. What this means in practice:

• Daily use of tools such as Claude, Claude Code, Cursor, and GitHub Copilot
• AI-assisted implementation, refactoring, test generation, and boilerplate
• You focus on architecture, edge cases, and quality
• You review all AI-generated output with a trust-but-verify mindset

This role is not a fit for engineers who are resistant to AI-assisted development or who rely on AI output without understanding the code being produced.

Qualifications

• 8+ years building production mobile applications, with deep iOS/Swift expertise
• Working proficiency in Kotlin, with the ability to contribute to and review a production Android codebase
• Hands-on Kotlin Multiplatform experience integrating shared code into native apps
• Experience building offline-first mobile apps with real-time, two-way data sync
• Experience with mapping SDKs and location-heavy applications
• Experience leading or mentoring mobile engineers
• Strong CI/CD experience for mobile, such as Fastlane, Bitrise, or GitHub Actions
• Clear written and verbal communication in English; comfortable working async across time zones

Requirements

• Lead the evaluation of Kotlin Multiplatform for sharing business logic across Android and iOS, and own the recommendation
• Architect and build our first iOS app, targeting iPads used by drivers in the field
• Contribute to and review work in our existing Kotlin Android app — shared architecture decisions serve both platforms
• Strengthen offline-first architecture: local persistence, background sync, conflict resolution, and reliable photo capture/upload under poor connectivity
• Work with maps, location, and in-app navigation in a location-heavy product
• Set mobile engineering standards across iOS and Android through code reviews, architectural guidance, and mentorship
• Collaborate closely with backend, design, product, and QA in a fast-moving startup environment

Nice to Have

• Deep Android production experience, including shipping and operating Android apps at scale
• Firebase/Firestore
• Camera, photo capture, or on-device vision/ML experience
• Logistics, field service, or B2B SaaS background

What We Look For

• Ownership: You take problems through to resolution and sweat the edge cases that matter in the field
• Judgment: You weigh new technology critically — adopting KMP or not is a decision you will help make, not inherit
• Communication: Proactive, clear, and async-friendly; missing context is surfaced, not assumed

Contractor and Location Notes

• This is a contractor role, not full-time employment
• Senior-level ownership and reliability are expected
• This role is open to candidates located in Eastern Europe or LATAM
• Consistent overlap with U.S. working hours is required
