Senior Software Engineer (Mobile Platform - Guest App)

• We’re looking for a senior engineer who gets excited about operating at real scale — not just shipping a single mobile app, but owning the platform and distribution system behind thousands of them
• Improve our mobile developer experience — from local setup to CI/CD — so engineers across the company can confidently contribute to the Guest App
• Build guardrails, tooling, and automation that make shipping changes to thousands of apps safe and reliable
• Increase release reliability and app freshness across Apple App Store and Google Play
• Strengthen observability, monitoring, and operational workflows to quickly diagnose and resolve issues
• Leverage AI tools to build automations at scale across our release and distribution workflows
• Partner closely with our internal launch team — power their workflows, hear feedback quickly, and iterate
• Contribute directly to the Guest App codebase when platform and product work intersect
• Take ownership of cross-cutting technical initiatives from design through production
• Provide thoughtful code reviews and technical leadership to raise the bar across the team
• Help us build a great team — interview candidates, refer great engineers, and shape engineering culture
• Our Tech Stack; Mobile: React Native (iOS + Android), Infrastructure & Tooling: Buildkite-driven mobile CI/CD and release automation at scale (iOS on MacStadium, Android on AWS), including store submission workflows and OTA updates. Backend & Services: Node.js, MongoDB, PostgreSQL. Language: TypeScript everywhere

Benefits

• Work from anywhere: Our flexible policy lets you work from wherever you want.
• Equity in Owner: All full-time employees in eligible countries receive pre-IPO equity in Owner.
• Benefits to support your success: We set you up for success where you are and where you’re going.
• Healthcare Coverage: We offer comprehensive health, dental and vision plans.
• Unlimited PTO: Your schedule, your choice. We give our team members full empowerment to choose the time they want to work, and don’t micro-manage working hours.
• Team retreats: We love building real friendships with everyone that we work with, so we do several retreats per year – to deepen our friendships, celebrate our wins, and plan our future.

Preferred experience

• Experience building and maintaining mobile applications (React Native experience is a strong plus)
• 4+ years of experience building and shipping production applications, including experience owning releases end-to-end
• Comfort navigating complex and sometimes opaque external systems (e.g., Apple/Google developer workflows, certificates, provisioning, store review processes, compliance requirements)
• Experience improving CI/CD pipelines and automating build and release processes
• Experience owning mobile app distribution — including shipping releases through the Apple App Store and/or Google Play, managing build pipelines, release workflows, versioning, and store compliance
• High degree of cross-functional collaboration — past colleagues in product, design, and business would speak highly of your teamwork
• Strong experience with TypeScript
• Experience at a product-focused startup, scale-up, or technology company
• Strong sense of ownership and drive, excellent communication, and a proactive approach to identifying and solving ambiguous, cross-cutting problems
• Track record of increasing release reliability and operational visibility (monitoring, alerting, debugging production issues)
