Why join koodos labs?

koodos labs is building personal intelligence that works for the person it represents.

Our mission is to put personal intelligence within your control: to help people bring together the context they choose, understand and refine what Shelf learns on their behalf, and decide how that context can be used.

We built Shelf to make that vision useful and fun in the real world.

What we’re building

Millions of people choose to connect Shelf to services like Spotify, Netflix, Amazon, YouTube, Goodreads, and more. Shelf aggregates that activity on their behalf, and every rating, comment, correction, or addition helps refine the picture.

Users and creators have already built hundreds of personal apps on Shelf powered by that context. Because Shelf asks people to encounter, trust, correct, and use software’s understanding of them, those moments cannot feel like generic AI output or a dashboard. They need to feel intentional, tactile, and trustworthy.

The Opportunity

Shelf is native iOS, built in Swift/SwiftUI. We moved off Capacitor specifically to chase the things that make iOS feel like iOS: gestures that read your intent, motion that anticipates the touch, widgets and Live Activities that do real work, and the frame-by-frame craft that separates apps people use from apps people love.

We have strong design taste and strong native architecture. What we’re looking for is someone who lives at the seam between them.

This role helps define what personal intelligence feels like in someone’s hands, by elevating the interaction quality and polish of Shelf’s most important native iOS surfaces.

The Work

  • Elevate Shelf’s most important native iOS surfaces, with particular attention to responsiveness, motion, gesture behavior, transitions, haptics, and tactile detail.
  • Partner closely with design and engineering to turn product directions into polished experiences.
  • Own the implementation quality of interaction-heavy surfaces across the app.
  • Help make personal intelligence feel legible and delightful, especially in the places where people see, refine, and control the context Shelf has assembled on their behalf.
  • Contribute to platform-native moments across iOS, including widgets, Live Activities, App Clips, transitions, and other surfaces where the platform itself becomes part of the product.
  • Work inside an evolving product and visual system without needing to reinvent the app from scratch.
  • Who We’re Looking For

    The kind of iOS engineer who has a TestFlight history, a personal app or two on the App Store, and strong opinions about haptics.

    You’re likely a good fit if you:

  • Have shipped Swift/SwiftUI work you’re proud of, whether indie apps, side projects, or polished features inside larger products.
  • Have a design engineer’s eye and can reason about motion, density, hierarchy, and interaction quality rather than just implementation correctness.
  • Are disciplined inside an existing system and can improve it without unnecessarily forking or refactoring it.
  • Have deep native iOS instincts across widgets, Live Activities, App Clips, gesture recognizers, custom transitions, and related surfaces.
  • Use AI tools heavily and thoughtfully to increase your throughput without lowering your judgment.
  • Work well asynchronously and communicate clearly through written updates, PRs, and critique.
  • Bonus signals include indie apps with a following, App Store features or awards, social/media product experience, public writing on iOS craft, animation work with Rive/Lottie/custom layers, or a portfolio site that itself feels designed.

    Logistics

    Remote. Part-time and project-shaped, with flexibility on weekly hours as long as throughput is consistent. We typically start with one well-scoped paid project so we can calibrate together. For the right person, we’re open to a longer engagement, equity, or eventually a full-time role in NYC.

    To Apply

    What we want most is the work itself: an App Store link, TestFlight build, video of an interaction you’re proud of, or a personal site. A short note on the most interesting iOS feature you’ve shipped, what made it hard, and what you’d do differently is helpful but not required if your portfolio already says it.
