Mobile App Developer (Flutter / React Native) at Bolder Apps in BR
Skills
Job Description
We're hiring a mid-level mobile developer to build and ship cross-platform apps for our clients. You'll own features end to end, from spec to store release, using Claude Code and other coding agents as your default workflow rather than an occasional assist. This isn't a role where you get handed tickets and a Figma file. You'll make architecture calls, argue with App Store reviewers, and be responsible for what ships.
About Us
Bolder Apps is a product development studio that partners with US-based startups and established companies to build and scale innovative digital products. We specialize in AI-powered development, full-cycle product creation, and engineering team augmentation. Our mission is simple: build bolder, faster, and smarter.
Our Culture & Values (read before applying)
We move fast. We take ownership. We work with AI, not against it. And we expect everyone to bring ideas, not wait for instructions.
There are no daily checklists, no micromanagement, and no corporate politics. Instead, you'll have autonomy, trust, and a team that's always ready to help you grow. At Bolder Apps, impact matters more than titles, and curiosity matters more than seniority.
If you want a place where you can level up fast and actually see your work making a difference - welcome aboard.
Responsibilities
Build and ship cross-platform apps in Flutter and React Native, from spec through store release
Own the release pipeline: builds, signing, TestFlight, Play Console submissions, staged rollouts
Wire apps to real backends. Auth flows, REST and GraphQL, offline caching, background sync, push notifications
Drop into native code when the cross-platform layer runs out. Platform channels, native modules, Swift and Kotlin bridges
Use coding agents to do most of the typing, then review what they produced before it merges
Test on real devices, watch the crash reports, and close the loop on what you find
Wire apps to Supabase and Firebase. Auth, access rules, offline caching, push, and server routes in front of third-party suppliers
Keep performance honest. Cold start time, frame rates, bundle size, battery drain
Work directly with product owners and designers without a translation layer in between
3+ years intensive mobile development, 5+ apps shipped to the stores. Be ready to walk us through any of them and defend the architecture.
Agentic development as your practice, not a tool you've tried. A setup that produces consistent output and a clear account of where you've learned not to trust it.
You read what the agent wrote. The auth flow that's almost right, the query with no index, the state that survives a hot reload but not a cold start. Shipping unread output is the fastest way out of this role.
Fundamentals that predate the agents: software architecture, relational data modeling, app lifecycle and backgrounding, permission models, OS fragmentation.
APIs end to end. REST and GraphQL, auth and token refresh, pagination, retries and timeouts, webhooks, versioning. You've integrated a third-party API with bad docs and worked out the real behavior yourself.
Store submission and policy fluency. Provisioning, signing, package IDs, privacy declarations, review guidelines. You've had a rejection and cleared it on the second try.
Platform conventions. Apple's HIG and Material well enough to catch what a spec left out: left-edge swipe goes back, minimum tap targets, destructive actions confirm, loading states exist.
Security ownership. Anything compiled into an app is readable. You've moved supplier calls server-side to fix it, and written Supabase or Firebase access rules that were wrong in production.
Failure modes you catch before QA. Denied permissions, large text on small screens, hung uploads. You don't swallow a network error and return an empty list so the screen looks fine while the backend is down.
Work on products aimed at the US and global markets, not internal tools nobody outside the company will ever open
Real scale, fast. Some of what we ship goes from launch to hundreds of thousands of users in weeks
A shot at building the next unicorn. We partner with founders early, so the app you architect this quarter may be the one raising a Series A next year
Fully remote, async-friendly. Work where and when you do your best work
Real autonomy on the agent setup, architecture, and workflow. We don't dictate process
Tooling budget for model APIs, agent subscriptions, and anything else that makes you faster
Variety of products across client projects instead of one codebase for three years
