What you'll do

The Kai app (most of your time)

• Work closely with the backend team to build new client-requested features and data collection methods

• Own the gaming layer: XP and level-ups, badges, daily quests and the rewards store

• Make the app feel alive with motion (Lottie, flutter_animate, confetti, custom transitions) without hurting performance on mid-range Android phones

• Build offline-first: an encrypted local SQLite database (Drift) that syncs with our API, so people can finish quests with low or no signal

• Work with device capabilities: location, Bluetooth, sensors, background tasks, push and local notifications, and permission flows that respect both users and App Store review

• Ship often. New builds go out to the App Store and Google Play about every week

The Management Dashboard

• Build admin and client screens in Next.js: project authoring, audience targeting on maps, submission review queues and analytics charts

• Keep the dashboard and app in step, so what a client configures on the web renders correctly on the phone

Design and UX

• Be the engineering counterpart to our design firm. Review Figma files early, flag edge cases (empty, error, loading, offline, small screens) and help grow a shared component library

• Turn designs into polished, animated, accessible screens, and push back when a design doesn't survive real users, real devices or patchy connectivity

• Improve the product with data: read PostHog funnels and replays, spot where people drop off, and propose fixes

What we're looking for

• 5+ years building and shipping mobile apps, with at least 3+ years of production Flutter

• Solid Riverpod (or a comparable reactive state pattern you can map onto it quickly) and a clean grasp of widget composition and rebuild performance

• A strong UX eye: you notice spacing, motion and copy, and you can explain why a flow works or doesn't

• Experience working with design agencies or in-house designers from Figma, including giving feedback before build starts and flagging edge-cases

• Experience with Figma Dev MCP

• Offline-first or local-database apps (Drift, SQLite, sync conflicts)

• Gamified, consumer or rewards products; animation-heavy UI with Lottie or Rive

• Accessibility and localization at scale

Nice to have

• React and Next.js experience (TypeScript, Tailwind) for dashboard work

• Native iOS (Swift) or Android (Kotlin) for plugin and platform-channel work

• Comfort with product analytics (PostHog, Amplitude, Mixpanel)

Tooling: Figma, GitLab (CI/CD), Linear, Xcode and Android Studio. We use AI coding assistants (Claude Code) daily and expect you to be comfortable reviewing and steering AI-written code.

How we work

• We build for the long term. Before we ship, we ask where it breaks, how long it lasts, and whether it can grow

• EQ matters as much as code here. We'll trade some raw skill for someone the team wants to build with

• We write simply. We're remote-friendly, and concise writing is how we think clearly

Probably not for you if

You'd rather leave the UX to someone else. Or you need a big team, a spec for everything and a dedicated QA crew before you ship. Here, you'll wear more than one hat.

Why now

Hard, valuable, fun. Making data collection feel like a game, on any phone, anywhere, hasn't been done well. Your first week, you'll build side by side with Maks, our CTO, in person if you like, and ship something real.

How we hire

No AI screens, coding challenges, etc. A couple of hours building with us instead.
