Senior App Engineer

Team Size: Small, high-impact product team

Location: Remote or Chattanooga, TN

Type: Full-time

We help families preserve the things that only exist once.

From VHS tapes and film reels to printed photos, negatives, slides, DVDs, camcorder cassettes, memory cards, and phones, we digitize the media that matters most so families can revisit and share those moments for generations to come.

But we believe the future of Legacybox is much larger than digitization alone.

We are building a long‑term family memory platform designed to help families preserve, organize, explore, and share their history together.

We are not in the digitization business. We are in the irreplaceable business.

We are hiring a Senior Mobile & TV Platform Engineer to help transform Legacybox from a web‑first product into a native, multi‑screen family memory experience.

This role sits at the intersection of product, engineering, platform architecture, video/media systems, and consumer experience.

You will lead the technical evolution of our customer experience across native iOS and companion TV platforms
, helping families engage with their memories in the places where they naturally relive them: on their phones, on the couch, and together as a household.

That means helping us build and scale experiences across:

• native iPhone and iPad apps
• Apple TV (tvOS)
• smart TV platforms (Roku, Android TV / Google TV, Fire TV, Samsung, or similar)
• media playback and long‑form video experiences
• photo browsing and memory viewing experiences
• account, family, and multi‑user experiences
• cross‑platform architecture and shared logic
• performance‑sensitive playback, storage, and sync systems

This is not a traditional app maintenance role.

We are looking for someone who understands that our product is not just software. It is how families experience irreplaceable memories together.

• Help translate our web application into a best‑in‑class native iOS experience
• Build and improve iPhone and iPad experiences that feel fast, intuitive, and deeply polished
• Define where native experiences should differ from web, rather than simply replicating screens
• Improve performance, offline resilience, responsiveness, and platform‑native behavior

• Architect and launch companion TV applications across priority platforms
• Create simple, elegant playback experiences for home videos, photos, and shared family memories
• Design for lean‑back, remote‑first interaction patterns
• Help make Legacybox a product families experience together, not just individually

• Partner with engineering leadership on long‑term architecture decisions
• Identify what should be shared across platforms vs. purpose‑built natively
• Improve reliability around APIs, authentication, media handling, caching, and sync
• Help establish scalable engineering patterns for mobile and TV products

• Improve long‑form video playback, chaptering, scrubbing, and discovery
• Build rich photo and memory browsing experiences
• Optimize performance for large media libraries and asset‑heavy experiences
• Ensure speed, reliability, and polish across lower‑bandwidth or constrained environments

• Partner closely with Product, Design, Backend, and Platform teams
• Contribute to engineering culture, code quality, testing, and release rigor
• Help us move fast without creating fragile systems
• Raise the bar for craftsmanship across all customer‑facing software

• 5+ years experience in iOS, mobile, connected‑device, or consumer platform engineering
• Strong experience building native iOS applications using Swift and modern Apple frameworks
• Experience shipping production‑grade apps to the App Store
• Experience with video, media playback, streaming, or large asset‑heavy interfaces
• Strong systems thinking around architecture, performance, and scalability
• Comfort working across frontend, API integration, and product decisions
• Ability to independently drive initiatives from concept through launch
• High craftsmanship and strong attention to UX detail
• Experience working in small, fast‑moving product…
