Sanity Check
This role is remote in Canada. Or in-person in San Francisco.
We can only sponsor a TN Visa if you come to the San Francisco office (you are a Canadian citizen moving to the US).
If you are remote in Canada, you must be a Canadian Citizen or a permanent resident; we will not sponsor your visa.
About The Role
This isn't a role where you'll be tweaking padding on someone else's components or shipping reskins of web flows wrapped in a WebView. You'll own our mobile app end-to-end — design and code — working directly with the founders to ship native experiences that move money in the real world.
Our app is a bare-workflow React Native build with native modules for NFC tap-to-pay, biometric auth, and deep integrations with our payments backend. No Expo. The bridge, TurboModules, and platform-specific build pipelines are part of your job, not someone else's. We build inside Cursor, manage work in Linear, and use AI tooling as a core part of how we write and ship — not as a gimmick.
If you can't show us apps you've personally designed and shipped, this isn't your role. We're not looking for a frontend engineer who "cares about design." We're looking for someone who would have been a designer in another life and learned to code so they could ship their own work without compromise.
What You'll Actually Do
Own the Truss mobile app — design and code, from Figma to App Store, from pixel decisions to native module work
Ship features that field workers actually use in the dirt and rain — tap-to-pay, card management, transaction flows, onboarding
Work in the native layer when you need to — Swift/Kotlin bridge code, TurboModules, Fabric, platform build tooling
Drive design system decisions for the mobile app and push them back into our broader product surface where it makes sense
Use Cursor and AI-assisted workflows daily, including for the parts of native mobile development where the tooling is genuinely behind (you'll help us push it forward)
Make technical and design decisions that matter — we're early enough that what you build now defines the mobile product for years
What We're Looking For
A personal website that demonstrates design prowess and showcases apps you have personally designed and shipped. This is non-negotiable. Link goes at the top of your application. If it's a Notion page with screenshots of work you "contributed to," save your time and ours.
5+ years building production mobile apps, with deep React Native experience — hooks, navigation architecture, performance profiling, list virtualization, gesture handling, animation (Reanimated, Skia)
Real bare-workflow experience. You've written native modules. You've debugged a Hermes crash. You've shipped a build through both stores without an Expo abstraction in the way.
Comfort in the native layer — Swift/SwiftUI or Kotlin, Xcode and Android Studio, code signing, provisioning, the build tooling that React Native engineers usually hand off
Strong product design sensibility — typography, spacing, motion, information hierarchy. You can hold your own in a Figma file and you have opinions about why things look the way they do.
Hands-on experience with Cursor as your development environment (non-negotiable)
Actively using AI tools in your development workflow — not just curious about them, actually shipping with them. Bonus if you've found ways to make AI tooling useful for native mobile work, where most engineers say it isn't.
Experience with Linear or similar modern project management tools for day-to-day work
Serious background in real-time strategy games — Warcraft 3, StarCraft, StarCraft 2, Age of Empires, or similar (non-negotiable). We believe the strategic thinking, resource management, multitasking under pressure, and rapid decision-making that RTS players develop translate directly to how great engineers operate. If you know what APM means and why it matters, we want to talk to you.
Must be legally authorized to work in Canada (or eligible for TN status to San Francisco)
Bonus Points
You've shipped a fintech or payments app and understand the domain — NFC, EMV, tokenization, secure enclaves, the works
You've designed and shipped your own indie app that you maintain in production
You have a strong opinion about React Native vs. Swift/Kotlin native and can defend it without resorting to memes
You've worked at a startup before and thrive in fast-moving, ambiguous environments
You were ranked Diamond, Master, or higher in any competitive RTS
What We Offer
Competitive salary and equity — you're joining early and your compensation reflects that
Remote/hybrid flexibility (Canada-based) or in-person in San Francisco
Professional development budget and conference attendance
A small, sharp team where you'll have real ownership and zero bureaucracy
The chance to be the design voice for our mobile product, not a function that ships tickets
About The Interview
15 minute phone call with founder
1 hour technical + design video interview (we'll look at your website together)
If hired, first 2 weeks onsite with the founder
